are the fumes dangerous?


Answer
no
Carbon monoxide is a lot like an elusive criminal -- it's highly dangerous and you can't see or smell it. In fact, it's often called "the silent killer."


You can protect your family from the dangers of this deadly gas by taking preventive measures and by learning to recognize the symptoms of carbon monoxide poisoning.

Check out the following safety tips to keep your home safe from the build up of dangerous carbon monoxide. If you need more information about carbon monoxide poisoning and prevention, call the Poison Control Center at 1-800-POISON-1 (1-800-764-7661).

Traditionally, few people have considered gas ovens to be a major source of carbon monoxide (CO), even though all their exhaust products are often vented directly into the indoor air of a residence. Yet unvented space heaters with a similar output of combustion gases have been banned in many states because of indoor air quality (IAQ) dangers inherent in their use.

CO poisoning in homes is generally the most serious of the wide variety of IAQ problems, in that people can die quickly from it, whereas most other such problems can be considered chronic. Weatherization personnel must perform a variety of combustion safety tests to determine if CO is being produced by any of the combustion appliances in a residence. If they find dangerously high levels, the crew should know how to fix the problem.


CO and Its Effects

Carbon monoxide is a colorless, odorless, nonirritating, but highly toxic, gas. It is flammable and slightly lighter than air. It is produced whenever there is incomplete combustion of hydrocarbon fuels--that is, when there is insufficient air to burn the fuel completely. The highest concentrations of CO typically occur at start-up of the appliance. This is especially true of ovens, because little or no air can flow through the oven until the air inside it heats and rises out of the exhaust vent.

High levels of CO cause headaches, nausea, shortness of breath, dizziness, confusion, brain damage, and, in severe cases, death. CO strangles the victim by reducing the amount of oxygen that can get to cells and impairing the body's usage of oxygen even if it reaches the cellular level. Victims should be removed from the exposure, though symptoms often persist well after removal from the source. That is because the so-called half life of CO in blood--the time for the peak concentration to decline to half its original value--is about four hours.

Often the symptoms are similar to those of flu. People who may have been exposed to CO should go to the hospital for a simple blood test. Another option is to check carboxyhemoglobin levels in the blood using a breath CO detector. A relatively inexpensive ($95) attachment is now available for Bacharach MONOXOR II carbon monoxide monitors, which are widely used for combustion safety testing.

Symptoms are related to the exposure level and time of exposure. The U.S. Environmental Protection Agency (EPA) recommends that a person should not breathe CO concentrations of 9 parts per million (ppm) or higher for any eight-hour period; 35 ppm or higher for any one-hour period; or 200 ppm or higher at any one time. Moreover, a person should not be exposed to any one of these three conditions more than once per year. The World Health Organization and Health Canada recommend a maximum exposure of 25 ppm for a one-hour period. ASHRAE Standard 62-1989 recommends an exposure limit of no more than 9 ppm in a living space, and Japan has an indoor standard that limits exposure to 10 ppm for any duration.

Recommended Oven CO Test Protocol

All gas and propane ovens should be tested for combustion safety, since they can be a major source of carbon monoxide (CO).
Test the oven in its as-found condition (do not clean or adjust) before starting any weatherization.
Use an electronic CO meter with a range of 0 ppm-2,000 ppm and a resolution of 1 ppm, such as the Bacharach MONOXOR II. Older nonelectronic meters or diffusion tubes are not suitable.
Zero the CO meter. This is typically done outdoors in a rural or unpolluted area. Do not rezero for individual houses. Calibrate the meter with 10 ppm and 500 ppm calibration gas about every six months (check zero at this time).
Turn the kitchen exhaust hood on, if one exists, to avoid exposing test personnel to potential CO.
Insert the CO meter probe tip well into the oven exhaust vent (typically an opening about 1 in high by 5 in wide centered in the back dial section on the top of the stove). The intent is to monitor the exhaust gases inside the oven exhaust before they are outside the oven and diluted with air.
Turn the meter on and then turn the oven on bake at 350deg.F with the oven door closed.
Watch the CO meter reading rise and record the peak or maximum reading. It should typically reach a peak within about 5 to 10 minutes and then begin to drop back down again to a steady value after a much longer time.
If the peak value is less than 100 ppm, the oven is not producing elevated levels of CO and need not be tuned or adjusted. Weatherization can continue.
If the peak value is greater than 100 ppm, turn the oven off. It is producing elevated levels of CO that could cause adverse health effects. It needs to be cleaned, tuned, or otherwise adjusted prior to or in conjunction with any air tightening of the dwelling.
If aluminum foil is lining the oven bottom, it needs to be removed or perforated along its edges so the secondary air holes in the oven bottom are not blocked. Such blockage is a major cause of high CO levels.
If the CO levels are still above 100 ppm after removing or fixing the foil, or if no foil is present, clean or tune the oven.
After the oven has completely cooled (at least 30 minutes with the oven off and the oven door open), turn the oven back on. Recheck the peak CO level in the oven exhaust gases.
Continue to adjust and recheck the peak exhaust CO level until it is below 100 ppm; only then continue with weatherization. Almost all ovens can be satisfactorily tuned in the field.
If, after repeated tuning attempts, the CO levels are still elevated, call the oven manufacturer. A few models cannot be satisfactorily tuned.
If the occupants complain of headaches, nausea, flulike symptoms, or worse, or if a home CO detector alarm has gone off recently, measure the occupants' CO blood levels with a breathalizer or recommend that the occupants get a blood test immediately at a hospital. Turn off all combustion appliances.
In extreme cases, it may be advisable to measure the maximum steady CO level in the kitchen air. After oven start-up it typically takes at least an hour to reach that level in loose dwellings and may take upwards of 8 to10 hours in very tight homes.
Consider giving any client whose dwelling has any type of CO combustion appliance, or at least those whose oven was not satisfactory, a home CO detector. Types with an LED readout are preferable (see "Conservation Clips: CO Detectors Not Created Equal" p. 63).
Two important caveats:

(1) This protocol does not apply to convection ovens, which have been known to blow hot air full of CO into the auditor's face. (2) A separate protocol needs to be developed for testing stove burners. In both cases, the indoor CO level should be tested.

Field Test Findings

Excessive carbon monoxide production from combustion appliances and CO poisoning are much more common than has previously been recognized. Among 25 homes with gas ovens tested in an ongoing survey by Montana Power Company's Low-Income Weatherization Program in Kalispell, Montana, CO concentration in the kitchen was found to be greater than 9 ppm in the cooking area in every case.

At Portland State University (PSU), my group measured IAQ in 23 low-income homes. One-third had ovens that caused levels in the cooking area to exceed the eight-hour 9 ppm standard after 20 minutes. However, 10 of the 23 cases showed CO levels increasing with time. (CO levels from the oven operation were monitored at 3, 10, and 20 minutes after turning on the oven.) That indicated the need to go back and continue testing over a longer time period. Most of the apartments or homes were fairly small and apparently leaky, demonstrating that leaky dwellings, as well as tight ones, are vulnerable.

In the few cases where CO released from stoves has been monitored, the stoves probably were not left on long enough to reach the maximum CO levels in the kitchen air. We conducted a follow-up study in Portland to determine just how long it takes to reach steady-state conditions (maximum indoor CO levels). Sixty ovens were monitored in two relatively leaky apartment buildings with the oven set on broil and the oven door closed. Half of the readings were over 9 ppm, and 15% were over the one-hour 35 ppm standard level.

The minimum time for an oven to reach maximum CO levels in the surrounding air was 20 minutes, but the average was 45 minutes to 60 minutes. Reaching equilibrium in that short a time implies that the apartments were very leaky, as was the case. Had they been much more airtight, it could have taken many hours to reach steady-state conditions, though the steady-state level would be higher than that in the leakier units. Tight homes also tend to have higher indoor CO levels from long-term oven operation.

The study also found that CO levels in the exhaust ports can indicate potential IAQ problems. In the field tests, about 40% of the ovens had CO production levels in excess of 50 ppm in their undiluted exhaust port at the time of the maximum CO reading in the kitchen air; the highest reading was over 2,000 ppm, and the average was 100 ppm. Ovens should be tuned if the steady-state CO levels in their undiluted exhaust gases is above about 25 ppm. Higher exhaust concentrations can produce indoor air readings above 9 ppm, with consequent adverse health effects.

Other field tests have corroborated the studies in Montana and Oregon. One low-income home I tested in Philadelphia had a CO level of 330 ppm in the kitchen air after only five minutes of oven operation! Similar problems were found with hundreds of homes in a study directed by Bruce Davis as part of low-income weatherization efforts in Arkansas. In almost every case the excess CO levels in the oven exhaust ports were reduced to below about 25 ppm after the oven was cleaned or adjusted.

It is particularly important to recognize that gas ovens are used as either the main or a supplemental space heating source in numerous U.S. homes, especially low-income homes. Two medical studies have indicated that 40%-50% of all urban low-income dwellings are heated with their ranges. It would seem reasonable that a similarly large fraction of nonurban low-income dwellings are heated in the same way. Given that about half of the ranges in the United States are gas or propane fired, and that about 20% of the U.S. population is classified as low-income, the potential problem is enormous.

The evidence suggests as much. In a recent study of the factors setting off CO detector alarms after their use was mandated in Chicago, stoves (either stove burners or ovens) were deemed responsible in 78% of the cases. At one Kentucky hospital, when patients coming into the emergency room with flulike symptoms were given blood tests, about 25% were found to have CO poisoning. These limited test results indicate that combustion appliance operation is often unacceptable. Monitoring for safety should be the first priority for weatherization crews.



Oven Repair

There is very little information readily available on how to adjust, clean, or otherwise tune an oven that is producing excessive levels of CO. However, experience in Arkansas with more than 300 ovens and in a PSU research project indicates that the following items should be checked:

Primary air adjustment--check the shutter opening. This is very important.
Fuel orifice size. The size will be different for liquified petroleum (LP) and natural gas.
Oven supply pressure. It is usually best to maintain the value stamped on the plate--usually 3.5-4.5 in of water (870-1,100 Pa) for natural gas and 9-11 in (2,200-2,700 Pa) for LP. Also check rated heat input on the plate and ensure that the orifice and pressure combination provides that input.
Secondary air path. Secondary air holes should be cleaned or cleared; pay special attention to the presence of aluminum foil lining the bottom of the oven and covering the secondary air holes.
Burner and pilot. These should be cleaned.
The good news is that most ovens can easily be repaired so that they emit little or no CO in the exhaust port, typically below 100 ppm peak or 25 ppm steady state. Ovens are basically simple devices, and repair tools cost little. A Dwyer, Ritchie, Bacharach, or other brand U-tube manometer to measure the gas pressure should cost between $10 and $40. A small brass wire brush, flair wrenches, and an asbestos glove are used for tuning as well.

Kitchen Exhaust Fans

Ventilating combustion products directly out of the kitchen eliminates the opportunity for them to affect occupants. This would get rid of CO and also oxides of nitrogen that are always present. These pollutants are a special concern in tight houses.

Kitchen fans are generally noisy, in part because they have relatively high flow rates. If they are too noisy, people will be reluctant to use them. Thus in selecting an exhaust fan to install in an existing home, look for one that is relatively quiet. It may require a fan with a somewhat lower capacity, but that is probably a good tradeoff. It's better to have a lower-power fan that is used than a high-power one that isn't. One fairly quiet option for retrofitting a fan into an existing home is remote installation: an axial fan that is rated for greasy air can be installed in an attic.

Finally, it is important to educate clients about the need to use their kitchen exhaust fan (if one exists) whenever the range is operating. Often people think that the only reason to use it is to get rid of cooking odors. Using fans can help reduce indoor pollutant concentrations by removing the pollutants at their source.

Whether or not an exhaust fan exists, safety tests should be performed in any home with combustion appliances, particularly before any weatherization efforts are undertaken. These simple tests have the potential to eliminate a serious safety problem.

vent free fireplace why do I get black soot?




robin oxfo


my vent free fireplace leaves a black smoke soot on my walls and ceiling what do I do to get read of it.Tired of washing walls all summer long to happen again HELP


Answer
Nice eh? And your breathing that crap too! That's why vent-free appliances are illegal in all of Canada and quite a few states. That's my rant for the day out of the way!

First of all, those appliances were never designed to be a primary heat source ( or a secondary one for that matter!). They were meant as a decorative applance that only sees a few hours of usage in a week. If it has always produced soot from the day it was first installed, you may very well have incorrect orifices for the fuel you are operating on. There should be a rating plate on the burner somewhere telling you what fuel it is set up for and how many btu the burner is. Confirm that the burner is set up for your fuel. If it is not, you need to contact the manufacturer for a proper conversion kit.

If this is a problem that has suddenly developed, I would suggest you have a certified technician come in and clean and service the appliance. There is a specific tool ( a monometer ) that is required to precisely adjust the fuel pressure to the appliance. This isn't something you want to try and repair yourself. If you get it wrong you could be producing harmful emmisions like carbon monoxide.

I sincerely hope you have carbon monoxide detectors in that home! If you don't, get some right away.

Good luck with it and be safe!

I have a Kidde Combo Smoke Alarm amd Carbon Monoxide Detector. Last night it was beeping every minute or so. I took batteries out tested for 1.18 volts , they're low. I put in brand new Energizer Max A A's each measure 1.57 volts digital meter. They were new out of the Wal Mart package. Still beeps once a minute. I double checked position/ polarity , they still beep once per minute?


Answer
most likely you need to press (or press and hold) the 'test' button.

What can I do about a smoke detector than uses batteries very frequently.?




Pikesville


Both ULI and Kidde detectors installed in my house seem to be eating batteries . The ULI detector was manufactured in 2009. The Kidde one in 2010. ULI says it is warranted for 5 years, Kidde for 10 years. Kidde one has suddenly been false alarming carbon monoxide detected when hard wired. Could the hard wiring need to be replaced? My house was built in 1986. Detectors have been replaced several times over the years. The combo carbon monoxide/smoke detectors seem to have more false alarms and are eating up 9 V back up batteries. Help!


Answer
If the voltage is wrong it could be killing the alarms and they are constantly on the battery hence the reason they seem to go through batteries and false alarm.

You could have AC detectors and your home smoke detector circuit is DC (not good).

You could have DC detectors and the power on the line is AC(not good).

Or the voltage could be wrong it may be 120v ac and the detectors are 24vac. (not good)

Sounds to me like it is time to break out the volt meter and do some sleuthing and them go get the right detectors or rewire the detector power circuit in your home.

Why is everyone in my house light headed and dizzy?

carbon monoxide detectors walmart on ... Alert AC Powered Carbon Monoxide Alarm: Home Security : Walmart.com
carbon monoxide detectors walmart image
Q. For the past 30 min literally everyone in my house has been light headed and dizzy. They also have a head ache. When I left my house to go to my friends house across the street to work on a project I was fine but then when I walked into my house the same thing happened.

Wtf is going on? I feel like throwing up


Answer
Do you have gas heat??

Get everyone out of the home immediately and call your local fire department (or 911 since you are all symptomatic). The fire department should have a carbon monoxide detector that they can use inside the house to determine if there are toxic levels present. Your family is experiencing symptoms of exposure. If left in the home long enough you could all lose consciousness and die from lack of oxygen.

FYI: Carbon monoxide poisoning is the leading cause of accidental poisonings in America!!

You can purchase a carbon monoxide detector at any hardware store and most department stores (Walmart, Target, etc). You should purchase a few and place them throughout your home. They will alarm when CO2 levels are unsafe.

My girlfriend has been having these symptoms, and we have no idea what going on. Help!?




iPlayH3


Symptoms include : dizzyness,massive headaches, loss of breath, severe coughing, dehydration, and pain in her upper chest, i guess you could say heart. She also vommited today and had a nose bleed.
Really need some help!



Answer
There are a number of things that this could be, but the most serious is carbon monoxide poisoning. If she lives with other people, they would all have the same symptoms if this is carbon monoxide poisoning - you can rule this out if other inhabitants are not sick. If you think this could be CO poisoning, she should not sleep or spend any time in her house until it is checked by the fire department or checked with a carbon monoxide detector/alarm that you can get from a Walmart.

In the city of Syracuse. I need to know if its true before I call and demand that they instale one. We bought one to put in the nursery for the baby (when he comes LOL I have to get everything done now so I know its done) Thanks for the help.
hahah rolfl I did not catch that I typed dioxide instead of monoxide. LOL thanks for pointing it out!!!



Answer
Not true! If you have electric heat, range, etc. there is no carbon monoxide unless you light your furniture on fire!

New York
N.Y. Exec. Law § 378 â Standards for New York state uniform fire prevention and building code.
Requires New York Fire Prevention and Building Code to adopt standards for installation of carbon monoxide detectors requiring that every one or two-family dwelling constructed or offered for sale after July thirtieth, two thousand two, any dwelling accommodation located in a building owned as a condominium or cooperative in the state constructed or offered for sale after July thirtieth, two thousand two, or any multiple dwellings constructed or offered for sale after August ninth, two thousand five shall have installed an operable carbon monoxide detector of such manufacture, design and installation standards as are established by the council. Carbon monoxide detectors required by this section are required only where the dwelling unit has appliances, devices or systems that may emit carbon monoxide or has an attached garage.

Deanna


The exhaust pipe is literally 2ft from the door of the apt. In California. Everyday it's in and out with an SUV! No carbon monoxide detector was provided by landlord. I had to get one myself. I have 2small children in the house and I'm worried about our health. Is there a law that protects us from this?


Answer
Who has access to the garage really should be provided for in the lease; if it isn't, talk to your landlord about setting up clearer terms.

That said, unless he's idling in the garage, you don't have to be that worried about carbon monoxide.

Carbon monoxide detectors in apartments?




Allie


I have tried looking, but can't find the answer online. Is it illegal for my apartment complex not to have a carbon monoxide detector in my unit if I have a gas stove? I live in Virginia. Also does anybody know how long an apartment has to fix items that are wrong with the place from when I first moved in? I've lived here for 4 months and we still have a terrible bug problem. And our front door leaks and floods our kitchen any time it rains. Thanks for any advice.


Answer
here in california, it is supposedly required by new law that all rentals (including apartments) have the carbon detectors....BUT i am still waiting for my landlord to put one in =D.

contact your state's housing agency (not sure of the name but i'm pretty sure all states in the USA must have this agency). find out what your rights are as a renter. also, if you have mentioned verbally to your landlord about the issues and nothing has been fixed yet. i would submit it again in writing though (as proof). and contact your agency as well.

good luck!

Searching to buy a guard dog - what breed would be the best for me?




ArmywifeCF


Hello,
We are about to move to the new house, and we need to buy a dog to guard the property. So far I would like a German shepherd and my husband would like a Rottweiler but it is not a definite choice- maybe some other breed too. I have to have in count the following:
- Dog has to be strong enough to stop intruders from approaching the house (the whole property is well fenced)
- Has to be able to live outside in his own house (here temperatures never fall below 2-3 C )
- Should obey both myself and my husband (especially in the matter of allowing visitors to enter)
- We have a 5 yr old cat that lives in the house with us but should not be harmed if accidentally goes out
- We have no and do not plan children

Thanks
edit:dog has to live outside because we are home only nights and weekends, not because we don't want to interact-of course we will



Answer
If you can't house your lone dog inside with your family, you are not prepared to have a dog and should not have one. Dogs are pack animals and rely on the attention, affection and interaction they get from you. Unless you plan to have multiple dogs that will provide the attention and interaction a dog requires to each other, leaving a dog outside and alone is cruel and often results in behavioral problems like barking, digging and aggression. Since outdoor dogs bark so much, people tend to ignore them anyway. My neighbor had one that barked all the time, which did not endear him to the neighborhood. Nobody payed attention and things were stolen from the alley all the time. Someone even got past the dog and stole a motor scooter right out of his yard!

If you are just looking for a way to protect your home, there are plenty of other options. You can get a security system - these can now be fully integrated with motion sensors that will not pick up your cat, glass breakage detectors, fire and carbon monoxide detectors, remote monitoring, mobile panic buttons for police and medical, cameras, DVRs, etc. Mine even has wireless signal (so you can't cut it off by cutting my phone line). You or your husband is in the military, right? You guys must have guns around and know how to use them, or if he does and you don't, have him teach you and get you a 38 or a 9 - good man stoppers with not much recoil. If you can't stand the thought of a gun, and a high tech security system just isn't enough, get a panic room.

Even the cheapest security system is better security than an outdoor dog that feels unloved and abandoned. If you have a townhouse, the solution is simple - break in from the front yard. If you have a single fence for your whole house, often dogs that feel abandoned and alone will roll over on the owners for a piece of meat and a scratch behind the ears. A professional will generally case your house for a while, and may even befriend your outdoor dog while you are out. If your dog becomes aggressive due to the extended solitude, that is a liability for you. Dogs love to dig, and can make quick work of the dirt under a fence if they want to. Children and teens can often be cruel to outdoor dogs, provoking them further. If your outdoor dog escapes while you are out all day and attacks somebody (who is not going to admit they teased your dog for the past month), that is your liability. I could keep listing off reasons why you should never keep a dog outside its whole life, but I suggest you start with the articles below and then speak to some animal rescues about responsible dog ownership, then determine if you are willing to make room in your family home for one more or if a different security solution would be better for your family.

What is this loud beep in the house?Fire Alarm?

carbon monoxide alarm 1 beep on Basic Functions | Smarter Smoke Alarms | This Old House
carbon monoxide alarm 1 beep image



OWL


Every about five minutes a loud quick beep hurt my ears,I think I once heard that it might be the fire alarms low on battery can it be this? I heard it in many other houses too.like my Grampa's House and friend's houses.What can this be?It's driving me NUTS!


Answer
READ EVERY WORD FIRST, ALL OF THEM, PLEASE!!!!
Well that's an easy one, I am assuming you are young since you reference Grandpa. Note the beep has to be from something electronic Possible sources: Burglar Alarm company backup battery to the main system is weak, the remotely located wireless window/door sensors have batteries that when dead make the Alarm console beep.

A smoke detector is likely. I have some that mount directly to the wall and some to a bracket that is mounted and you turn the "front" of the detector CCW or CW to remove from the bracket. You need to know if the smoke/fire alarm is a battery unit (CLUE: IF YOU CAN TAKE IT OFF WHERE ITS MOUNTED AND IF IT HAS NO WIRE INTO THE WALL/CEILING ITS BATTERY, NOW TURN IT OVER TO THE "WALL SIDE", MAYBE THERE IS A VISIBLE 9V BATTERY COMPARMENT SPOT RIGHT IN FRONT OF YOU), if not it might be a open the cover unit, so, open the cover by looking, AND THEN LOOKING AGAIN, you might have to pry a "tab" or unscrew a screw before opening, when you see the 9v battery you will be half done, (if YOU DON'T ABSOLUTELY KNOW WHAT A 9V BATTERY LOOKS LIKE STOP SEE TEST BUTTON BELOW). PLEASE don't mess with the "120" volt smoke detector, call the company if it's the "beeper" [all non battery smoke detectors may not be "120" volt but they may be 12-24 volt AC or DC so they still might be dangerous] (I say that more for those who might nitpick me).

If it really beeps every five minutes it wont hurt to pull the 9volt battery and wait 7 minutes. TEST SECTION: If you can't wait, be brave, re-read above and extract the battery, put the 9v battery to your tongue, if it mildly tingles it's a dead battery, if it smarts put it back in and wait the "5" minutes. NOTE YOU CAN'T DIE FROM THIS EXCEPT MAYBE IF YOU HAVE A PACEMAKER OR BUILT-IN HEART DEFIBRILLATOR SO THOSE FOLKS DON'T "TONGUE" IT.

Or best of all, get a volt meter from an electronics pal. 9 volts minus 1.8=7.2 volts = battery no good (if the battery is low by 20% its dead, this even applies with 6 volt, 1.5volt etc.( -20% is my guide for alkaline batteries),

Also if you are afraid just press the TEST BUTTON, on the smoke detector, if it has one, buy a new one if it doesn't have a test button, its too old or the owner was too frugal. [IF IT WONT SOUND OFF UNDER TEST ITS DEAD, IF IT DOES SOUND THEN YOU CAN NOW KNOW IF ITS "YOUR BEEP"] Now identify if its a 9v battery by taking it gently off its mount or bracket mount also see above again. See the test section if you feel braver.

If you succeed in removal AND REPLACE THE 9V note that I put all my detectors on a wall AS CLOSE to the ceiling on a 3-4 inch bread twist tie or better "wire" to a screw or thumb tack [ yes it looks fine if you do it right] for easy removal of batteries and no loss of sensitivity. Generally smoke rises driven by the heat, so the closer to the ceiling the better.
(this wire mount idea is at your discretion, I'm sure some fire guy is gonna disagree but in my experience of an actual house fire in 1987 with the detectors mounted as such, they saved my sleeping wife and cat!)

Check for a carbon monoxide detector and again make sure its not "120" volt, press the test button. A UPS on your computer with a near dead battery makes beeps. A medical device for "Gramps" may be at fault. a cell phone or cordless home phone beeps when near dead. A microwave or new fridge with the door open can beep. An AC alarm clock can beep when its 9volt battery gets weak.. Get the common thread?

If after all that you can't isolate it, invite some other young folks over for sodas, [statistically better at hearing high pitched beeps] put the battery back in the smoke detector and have the young'uns stand at different parts around the seeming sound area to pinpoint the beep. Keep in mind that some beeps are so foxy that they are like a ventriloquist and "throw their voices" so move around like musical chairs till every one agrees. Need I say more?? Good Luck! WHEW

wired smoke detector keeps beeping I have turned it off at the mains but it is still beeping how do I stop it?




Sue H





Answer
I have worked in the electronic security industry for over 40 years, and have encountered many of my customers with this same complaint. Here are the most common causes of this problem.

1) You may have identified the wrong detector. In other words, the beep is coming from somewhere else, and not the smoke detectors. If you are absolutely certain that you have disconnected all power to the smoke detector then there is no way a noise can come from a detector that has no power. It is ether getting power from somewhere else, or you are hearing a beep from another device such as a carbon monoxide detector that is nearby.

2) Your smoke detector is one that is wired to an alarm system. In this case I highly recommend that you contact your alarm company for service because your smoke detector is getting power from a back up battery that is a part of your alarm system, and leaving the main power shut off will wear that battery down, and then you may have to have it replaced too.

3) Your smoke detector has a built in back up battery. You can shut off the main power to your detector, but it will still run on the internal battery until it dies, which could take several hours, or maybe even days. In this case you need to take the smoke detector down and see if there is a battery inside and disconnect it.

Most smoke detectors will come down by simply grasping the detector on the outer edges and giving it a twist either to the left or the right. If you look closely on the outer housing of the detector, there should be instructions on how to open it in raised lettering on the plastic. Be careful not to force it too much if the detector is expensive because most people end up breaking the housing or the mount of the device to the point it needs to be replaced with a new one.

The most common reason these detectors start beeping when there is no reason such as a fire, is because it has reached the end of it's useful service life. A very good quality detector should last about 10 years before it should be replaced, so if yours are older than that, you need to consider replacing them with new ones, and if they are wired in to your household power, or to your wired security system, then call in a professional service technician to have them replaced and tested for operation.

Best jammies for potty training? Keeping her warm in our arctic bathroom while she goes? ?

carbon monoxide detectors uk law on Stove & Fireplace Installation
carbon monoxide detectors uk law image



heartlosta


Ok, so my daughter wants to pottytrain, which is all good. She comes to me and lets me know when she wants to go sit on the potty and try because she has an Elmo potty book that she only gets to read while on the potty. However, the apartment we live in is heated by a reverse airflow heater located in the dining room, and it doesn't heat any further than the dining room and living room. We are not bringing the potty into the dining room, it's not an option as she likes to use the big potty more often than not when she's trying to go. So we'll already have to give up the warm fleece footie pajamas that she likes to wear all day long because she can't get them all the way off yet, but she doesn't like to wear jeans and whatnot because her room is really chilly too, although it's warm enough that she doesn't get sick, she likes to play in there. I just can't see putting her in a snowsuit, and all longjohns I see in her size are one piece. I plan on buying several garanimals sweatsuits to help keep her warm during the day, but what kind of jammies should I be searching for, that aren't too expensive? Do they make sink and toliet paper toddler locks? If we leave the bathroom door open, she wants to play kitty and unroll the toliet paper into a giant mess, as well as put some in the sink and turn it on to see what happens because she can stand on the toliet and reach the sink. She already flooded the apartment downstairs once, and we got a warning, so we've been having to leave the door shut, and with no vents it's very very cold in there. The other great feature in our apartment is lack of electrical outlets, there are none in the bathroom or the hall, so we can't put a little heater in there, and any outlets accesible by extension cord are so loose that plugs fall right out of them(my boyfriend has to hold the plug in while I sweep the floor) We've asked our landlord to replace or fix some things, his response was to install a gas heater in the bathroom that says right on the side, do not use in a bathroom- may rust out and leak carbon monoxide. Not to mention my boyfriends knees hit it when he sits on the toliet, and if it's hot he'll be burned, and it's within easy reach of my daughter as well, so we can't use it, period. Turning it on is not an option for obvious safety reasons.
So how best to keep warm, yet accesible for potty training?
Ideas please(and we can't move, we'd have to pay over 3500 dollars just to break our lease, plus a deposit on another apartment, and we just don't have that kind of money), and somehow this firetrap was certified as a legal residence.

Thanks!



Answer
Wow that sounds bad. Ok not going to send links etc but you can buy thermal vests to put under clothes. You can buy fleece sweatshirts in the day and even for her to sleep in. She is probably warmer in layers.

As for the heater in the bathroom that does sound daft. It sounds like the door should be shut when the bathroom is not in use because of your daughter able to flood it with your back turned. I would find a way to lock it, have a potty in her bedroom or dining room for emergency use but tell her she needs to tell you when she wants to use the big potty. By doing this there is the option for turning the heater on in the bathroom for short spurts of time with the door closed to heat the room. This could be done perhaps when she is in bed, with you and your boyfriend aware that it is hot and don't touch. The carbon dioxide factor of it is a concern though - and that is an understatement. You can buy carbon dioxide detectors for a small price - although how effective they are I don't know. You can also keep an eye on it to check for erosion.

I know you can't move out straight away but I would save up for that day. You can get padded pyjamas and fleece trousers etc, get warm socks etc. Are you with an agency that you can get extension plugs sorted - in the UK it is illegal to have unsafe things like that including carbon monoxide releasing equipment with yearly gas checks. Check what the rental laws are in your area so you know what you can ask your landlord for and what you can't.

How do you detect natural gas leak?

carbon monoxide detector detect natural gas on ... ) - China Gas Leak Detector Alarm, Carbon Monoxide Detector Alarm
carbon monoxide detector detect natural gas image



verset


This is probably a stupid question, but I've been an electric user all my life! I just moved to a house that uses natural gas for stove and water heater.

Does a Carbon Monoxide detector detect a slight natural gas leak? I ask because I was cleaning behind by range/oven, and I could smell a faint odor of what I think is natural gas. If there was a small small leak, would the carbon monoxide detector catch it?



Answer
The 2 answers above are correct. Before calling gas company you might want to see if pilot lights are all lit( if it has flame style pilot light). If a pilot light has blown out you will get a slight smell of gas because it is not being burned. If you have a newer style stove that clicks when you turn it on ( electronic ignition) then there won't be a standing pilot light and you probably have a gas leak.

How does a Carbon monoxide alarm work?




raver82


I never heard of a Carbon monoxide alarm before until my sister came home with one yesterday. I was just wondering how it works? if Carbon monoxide is colorless and odorless and whatever else how can you get it in a house what does it come from? I'm clueless about it. I spent most of science class in school asleep.


Answer
Hello raver82:

CO is deadlier than natural gas; because it is odorless/colorless, people don't realize that it is present. It will cause death with as little as 30ppm within 30 minutes. CO is extremely hazardous to infants, the elderly and people with breathing disorders or who have difficulty breathing.

The detectors must be powered at all times in order to work properly. The mechanism is able to capture the CO molecules and if a high concentration (over 15 ppm) are detected, it will sound an alarm.

Symptoms of CO poisoning are grogginess, headache, fatigue, sleepiness, irritation of the nasal passages and lungs, and sometimes vomiting or diarrhea. Some complain of experiencing the same effects of alcohol.

A CO detector is as important as the smoke detector. CO is a result of inefficient combustion of hydrocarbons; the largest source in a home is the family car(or truck). If you have a natural gas appliance (furnace, water heater or stove), it is a wise investment to have the CO detector. After the car, the other main source of CO is the gas stove. If you have a gas stove, it is critical that you have an exhaust hood or vent for the stove that exits outside the home.

carbon monoxide detector 10 year battery image



lkbwildcat


Last night at 1:00 am my smoke detector went off randomly for the first time ever. I had to tear it off from the ceiling to turn it off. There was no smoke so could it have detected carbon monoxide? Or was it just a malfunction because it is more than 10 years old?


Answer
when it does that it means you have to replace the battery

Carbon Monoxide detector is beeping every 30 seconds to 1 minute?




Bob


My Carbon Monoxide detector has been beeping every 30 seconds to 1 minute for like 12 hours.

Is this just a battery problem? I don't have the time to get a new one or a new battery today, can I just put it outside so I don't have to hear it and get one this week?

Thanks



Answer
Putting it outside will keep you from hearing the beeps, BUT, it will also keep the detector from doing its job. I suggest you buy a new battery. Better to be safe than sorry. How old if the detector? They should be replaced every 10 years or so, sometimes more often.

What, exactly, is happening to our blue planet?

carbon monoxide alarm 7 year on year carbon monoxide alarm fireangel 7 year carbon monoxide alarm ...
carbon monoxide alarm 7 year image



eyesea@jun





Answer
a short account of environmental happenings that are endangering the blue and some possible solutions

these are some Mega threats that endanger the planet

Exstinction,over population,deforrestation,
excess carbon emissions,desertification(land...
bad farming practises(landloss),
erosian(landloss),watershortag...
global warming,rising seas(landloss).

EXSTINCTION

we harvest fish faster than they can reproduce,
And habitat destruction,climatic change,
expanding populations,overexploitation,
deforrestation,desertification...
polution are responsible for mayor looses
of both flora and fauna,many for ever.
we are now witness to the first mass extinction
since the day of the dinosaurs.
species are being lost every hour.

OVERPOPULATION
the world population has doubled in the last 50 years
the fastest increase ever,since we became homosapian

each year farmers have to grow food
for an extra 70 million people,
many of whom are taking the forrests place.

DEFORRESTATION
if it continues ,is that we could end up looking like Mars.Without an atmosphere ,without water,without air,
with out life

the rain forrest and all other forests are getting smaller every day.
especially in south America and Mexico.
valuable species of plants become lost
and countles animals are killed into extinction.

the jungle of Lacadona one of
the richest environmental areas of Mexico
which produces 70 %of the countries water,
is home to thousands of rare species of flora and fauna
is loosing hundred of hectares daily
(2 millions hectares per anum)
despite nationwide campains on all tv and radio stations.
nothing can stop the destruction,
the same thing is happening in the Amazon regions ,
and probably in Asia as well,
and it is also the case in Borneo

the forrests make most of the water that we can drink
or use for agriculture(sweet water)
some is condensed from the sea but that reaches only the coastel aereas.
the bulk ,comes from the forests ,
and the rivers come from the rainfall
which comes from the trees.
the trees with precipitation,
feed the rivers when it is not raining
and keep them running all year round.

If we kill all the trees,we kill the rivers .
we kill the rain. we kill us.
the trees also absorb the heat in the day
and heat up the place in the night ,
so they keep the temperature confortable to live in.
trees evaporate a mist which ,which protects us from the strong rays of the sun

in the dessert the nights are freezing cold
and during the days you burn up.

CARBON EMISIONS
the world is producing more carbon monoxide
than the system can accomodate
the trees absorb carbon emisions ,
which is poison to us and they leave the oxygen
which we need to breathe.
in the autemn the colder seas absorb carbon emisions
that is produced by rotting flora .
and in the spring newly growing biomass
utilises the carbon that is released by the warmer waters

DESERTIFICATION

because of bad agricultural practises
and the resulting land loss
farmers are now cultivating highly erodable lands
and deforresting vast areas
the sahara is growing by 7 kilometres every day.

two major desserts in northern china
are growing together making one giant dessert,
causing dust storms making thousands of people refugese.
the planet is drying out at an alarming rate.

in the days of the dinasaurs this planet was under an aquiferus manta ,a mist that covered the entire earth
and there were no desserts.
Count how many there are today,and all of them are as a result of mans actions.
the sahara used to be forrests
arabia ,irak ,iran used to be fertile lands in biblical times
Ghengas Kahn burned all the forrests
and filled the wellS with water and
so turning vast lands into dessert.
BAD FARMING

Bad agricultural practises is turning
vast teritories into desserts ,because of
over grazing ,the exessive pumping of carbon aquifiers.
the surface aquifiers already having been depleted.
And the use of fertilisers and heavy machinery that compacts the ground which raises the salt in the soil.
Modern agriculture today is doing the same as ghengas kahn but in much bigger territories.
because agricultural lands are lost, farmers are forced to cultivate highly erodable lands,
to keep up with the growing demand for food.

EROSION
soil erosion is almost always as a result of human intervention.the trees are cut down.
these trees existed to provide a cover
against the rays of the sun.
which now dries out the soil ,
the wind can than easily blow away the dust that is formed this is wind erosian

because the trees are no longer there,
whose roots bound the soil together ,
and because their canapies of foilidge
no longer exist, the rain now has easy acces to the unprotected ,now dry surface
and the rain waters wash away the top soils.
this is water erosian

farmers plow large plots of land to plant,
as happened in the 20s in the USA,
they plowed in straight lines.
the winds came blew along the straight lines
and picking up speed removed millions of tons of top soil(wind erosian)

turning vast teritories into dessert
deprived of arable soil
today the farmers plow in circles and curves
to prevent this building up of speed by the wind.

but still vast sections of land are exposed to the sun which kills the micro biotic life that builds the black and rich top soil
and tons of water is evaporated by the sun.
NO TILL FARMING
A far better way is a very old concept
now newly applied called -no till farming.
after the inicial shaping of the land
the tractor is no longer used .or another type of plow
head is used which does not break and turn the soil over,but merely makes a deep cut
into which the new plants are planted or sown.
or the seeds are just stuck in an unbroken surface
,which is covered------- by mulch.

MULCH
mulch is a layer of organic material
which prevents the soil from drying out
by blocking the sun and maintaining its moisture
because the soil is now soft and moist
the earthworms devellop.
there is no better manure on this earth
than that from earth worms,
who also airate the soil their bodely movements
sucking in the air .
mulch also is a cover which protect the soil from the impact of heavy rains .
This brings the salt to the surface
and so makes the soil poorer.
mulch also is the food and conditions for a vast variety of micro biotic life that produces top soil

MUD SLIDES
In the mountains Mexico,
the increasing populations of indigenous peoples
are cutting down trees to plant corn ,
this land is productive for a few years
before it becomes poor and useless for farming.
the roots of the trees that have been cut down rot and tunnels are created with their disaperance.
with heavy rains these tunnels fill up with water
the soil lifts and moves down wards,
mudslides are caused.
large parts of the mountains are exposed to the rock.
the mud destroys the lands beneath and the exposed areas NEVER recover leaving the area without vegetation forever

to recover eroded soil is a lenthy process ,which involves planting, bushes ,grasses and trees to hold the soil and to create bariers to stop further movements on the surface.
and trap any organic matter that ends up there.we can help by adding mulch(chopped organic matter) and plant leafy plants to be chopped down for this purpose.there are various plants that are exelent for this pupose,
like a bean called nescafee which is a monster
in normal circumstanses ,it covers an enormous aera ,grows very fast creates tons of leaves ,
when fully grown it dies leaving a thick cover of rotting organic material behind.

WATERSHORTAGE
each year millions more people are consuming water
but this is but a fraction of what agriculture uses.
our consumption of water is ever increasing and our drinkable water supply is shrinking,because of polution,and the production of potable water is less all the time because of deforestation.

in Tasmania one can already exchange one litre of water for 2 litres of petrol.
it is predicted that the wars of the future will be for water.
the water we got in most populated places must be treated or purified before it is acceptable for human consumption.in Portugal and soutern Spain ,as in many places, wine is cheaper than water.
Which would explain the many drunk people there.

we are living in a bubble economy and when the bubble bursts
food prices will sky rocket,and so will the price of water.

GLOBAL WARMING(crop loss)
because of the green house effect and the desertification this planet is heating up.
Each degree rise in temperature signifies 10% crop loss

Global warming is in theory reversable,but it will mean global co operation between all countries,
and taking into account human nature and the world
politics ,it is unlikely that this will happen,
At least not untill we are all in the middle of planetary disastres and it becomes a battle
for the survival of humanity every where.

RISING SEAS
The northpole is melting ,and we will know it without ice in our life times.
this does not affect the sea level because it is ice that is already in the water.
Green land and the south pole ,which apperantly has a hole in the ozone the size of the USA,are another matter.
this is ice above the sea ,on the land, and melted water will return to the sea .
and so duely affect sea levels.
the sea has been rising for a long time.
in portugal remains of Roman villas have been discovered 3/4 of a mile in the sea,and in one town the locals say that the sea is eating their town .

in California and Florida ,arable lands have have been lost because of rising seas
so far only a few millions acres in total globaly ,but this will speed up with the increasing global warming.
And in Antartica arms of ice that even had names because the were so permanent have broken of into the sea.

SOLUTIONS
Global efforts to cut down on carbon emisions,reforestation to capture carbon,sustainable farming practises and ecomomic systems of irrigation,education on family planning to counter overpopulation,water harvesting( to fill up subteranian water supplies),
environmentally friendly energy systems,efficient public trans port to discourage the use of the internal
conbustion engine,global distribution of food supplies.
encouraging people(to return to the land) to be autosufficient (with the internet business is not any more confined to the cities),
urban planning to include vegetation,stop building more high ways,agricultural devellopment programs for 3rd world countries.

if every one in the world, who could,would plant a garden ,this would take the stress of the farmers,add to the bio-mass and humidity ,and put a lot more food into circulation.

so what you can do is plant a tree,clean up rubbish,leave bins for people to put their rubbish in,leave notice boards explaining that you cleaned and ask people to co-operate,

COMPOST
and dont put your own organic rubbish together with the rest,seperate and classify your rubbish,
70 %of contamination is because of organic material and this is the easiest to take care of ,
you make a small compost heap in a shady place in the garden and all the organic waste of the house
can go here ,at times cover it with leaves or sand.
the rich compost which results you put back on your plants.
this does not smell or create bugs,the decomposition kill about every thing.

PESTCONTROL
if you can have a couple of bantum chickens which eat 70%of garden pests and they do not rake the ground and kill the plants as ordinairy chickens do.

Fire alarm malfunction?




Jess1727


My kiddie alarm smoke/carbon monoxide detector had a low battery alarm. Upon replacing the battery and reattaching the wire, the alarm goes off continuously, setting off the same hallway alarm, and finally the 3 bedroom alarms. Pressing the button did nothing, finally I had to disconnect both kiddie alarms and remove the batteries to stop the "fire fire" alarms.
Is it possible both alarms are malfunctioning? Are any replacement alarms wired the same as the kiddie?

Thanks!



Answer
Maybe it a malfunction of the low battery warning. How old are the alarms?

â LOW BATTERY: When the batteries are low and
need replacing the red LED light will flash and the
unit will âchirpâ one time, followed by the warning
message âLOW BATTERYâ. This cycle will occur once
every minute for the first hour. After the first hour
the red LED light will continue to flash every minute
accompanied by the âchirpâ only sound. The voice
message âLOW BATTERYâ will sound once every
fifteen minutes during the âchirpâ only cycle.
This will continue for at least seven days.
⢠One âchirpâ every 30 seconds is an indication that
the alarm is malfunctioning. If this occurs call the
Consumer Hotline at 1-800-880-6788.
⢠After seven (7) years of cumulative power up, this unit
will âchirpâ twice every 30 seconds. This is an
"operational end of life" feature which will indicate
that it is time to replace the alarm.

I have a Kidde Combo Smoke Alarm amd Carbon Monoxide Detector. Last night it was beeping every minute or so. I took batteries out tested for 1.18 volts , they're low. I put in brand new Energizer Max A A's each measure 1.57 volts digital meter. They were new out of the Wal Mart package. Still beeps once a minute. I double checked position/ polarity , they still beep once per minute?


Answer
most likely you need to press (or press and hold) the 'test' button.

Difference between carbon monoxide alarm and low battery alarm?




Mike


I have a battery powered carbon monoxide alarm that started beeping a hour ago, but then stopped when I replaced the batteries.


Answer
Carbon monoxide (CO) alarm is triggered to sound, if it detects the presence of the carbon monoxide (CO) gas, a colorless and odorless compound produced by incomplete combustion, in order to prevent carbon monoxide poisoning. CO detectors detect and warn people about dangerous CO buildup caused, for example, by a malfunctioning fuel-burning device. In the home, some common sources of CO include open flames, space heaters, water heaters, blocked chimneys or running a car inside a garage.

While a Low battery alarm is triggered to sound, if the circuit detects that a battery power supply falls below the specified rating to run the detector device.

If your device have both the alarm you must distinguished the tone of Carbon monoxide alarm to the tone of Low battery alarm. Usually they are of different tones to differentiate them from one another.

In your case maybe the device had detected the presence of CO gas while in its position and triggered its alarm. But when you remove it from its place the CO gas had fade and blow away to the air and stop beeping. Thinking that it is a low battery you replaced it without testing the battery if it is really a low batt. All gas detector has a "Test Button", the test button on a CO alarm only tests the battery and circuitry not the CO gas sensor.

HAS anyone experienced Carbon monoxide and propane heaters?

carbon monoxide detector yellow light on Carbon monoxide detectors - Heating, water & electricity - Which? Home ...
carbon monoxide detector yellow light image



Gramma





Answer
Carbon Monoxide is produced during the incomplete combustion of propane. Incomplete combustion is defined as within the limits of flammability but higher or lower than the ideal ratio of 4 parts propane 96 parts air. Incomplete propane combustion can occur in one of two ways:

* Lean Burn - The ratio of propane to air is less than 4 parts propane. 2.5 parts propane to 97.5 parts air would produce a lean burn. A lean burn can be recognized when flames appear to lift away from the burner and can potentially go out.
* Rich Burn - A ratio of propane to air is more than 4 parts propane. 8.5 parts propane to 91.5 parts air would produce a rich burn. Recognizing a rich burn is very simple as the flames are much larger than they are supposed to be and are largely yellow in color.

Several products of incomplete combustion that are easily visible and if noticed, action should be taken immediately. Visible signs of incomplete combustion include burner flame appearance (as listed above), soot collecting on appliance windows such as that of a space heater and excessive water vapors forming on windows and cool surfaces during appliance operation. Appliance service and adjustment is needed if any of these visible signs of incomplete combustion are noticed.

Dangerous Levels of Carbon Monoxide - The Signs

Carbon Monoxide is a deadly toxic gas undetectable by smell that can harm or kill animals, plants and people. Carbon Monoxide poisoning is not limited to propane gas. It is a product of the incomplete combustion of natural gas as well. The best defense against Carbon Monoxide poisoning is to have working CO detectors installed throughout the living space of a home. Carbon Monoxide detectors are available at many stores as well as on the internet. If any of the following signs are noticed, take action immediately as a high level of Carbon Monoxide is likely present.

* Aldehydes - This toxic gas is detectable by smell and gives the sensation of a metallic taste in ones mouth after exposure and indicates Carbon Monoxide is most likely present.
* Health Symptoms - Carbon Monoxide poisoning causes headaches, dizziness, nausea, shortness of breath and light-headedness. Fresh air is needed immediately followed by medical attention.
* Dead Plants - Dangerous levels of Carbon Monoxide are likely if the plants in your home have all of a sudden died or are withering.

Action needs to be taken immediately if any or combination of the above are noticed.

My Gram's carbon monoxide detector is going off...?







She and her assistant have changed the batteries like twice...i'm about to go over there. She doesn't have a car... Any ideas what it could be?


Answer
She needs to get out of the house until she finds out for sure. Take the detector outside with them because it should turn off if there is no carbon monoxide to set it off. (just in case they think it is defective)

more info from the web.....

What to do if your Carbon Monoxide Detector goes off
What to do and who to you call when your carbon monoxide detector goes into alarm?

The manufacturer of First Alert, the leading brand of carbon monoxide detectors, recommends the following if the alarm goes off:
Turn off appliances, or other sources of combustion at once.
Immediately get fresh air into the premises by opening doors and windows.
Call a qualified technician and have the problem fixed before restarting appliances.
If anyone is experiencing symptoms of carbon monoxide poisoning: headaches, dizziness, vomiting, call the fire department and immediately move to a location that has fresh air.
Do a head count to be sure all persons are accounted for.
Do not re-enter the premises until it has been aired out and the problem corrected.

To identify the source/s of carbon monoxide, have a professional check the following :

Gas or oil furnaces are frequently the source of carbon monoxide leaks. Measure concentrations of carbon monoxide in flue gases. Check all connections to flue pipes and venting systems for cracks, gaps, rust, corrosion or debris. Check the filters and filtering systems for dirt and blockages. Check the combustion chamber and heat exchanger for cracks, holes, metal fatigue or corrosion.

Check furnace flame, burners and ignition systems. A predominately yellow, flat, lazy-looking flame in a natural gas furnace indicates fuel is not burning efficiently and is thus releasing higher than usual levels of carbon monoxide. Oil furnaces with a similar problem produce an 'oil' odor, but remember you can't smell, see or taste carbon monoxide.

Chimneys and venting systems must be carefully checked for blockages caused by debris, animal nests, cracks, holes or cave-ins. A blocked chimney or venting system can force dangerous gases back into your home.

Venting and fan systems on all fuel burning appliances must be inspected for proper installation to assure carbon monoxide is vented out rather than in. Don't forget gas water heaters, clothes dryers, space heaters or wood burning stoves.

Inspect fireplaces for blocked or bent chimneys or flues, soot and debris or holes in the chimney that could release carbon monoxide exhaust back into the home.

Stove pilot lights in a closed-up home can be a source of carbon monoxide build-up if not operating properly because they are not vented to the outside. Check to be sure they are operating properly.
Fireplace pilot lights can also produce carbon monoxide and should be checked regularly.
Never burn charcoal inside no matter how much you want to recapture summer and never use your gas stove as a heater. Keep the oven door closed and use it for cooking only.

Never leave a car running in an attached garage even if the garage door is open.

Taking time to understand the characteristics of carbon monoxide and how Underwriters Laboratories, Inc. (UL) listed carbon monoxide detectors work could save your life.

According to UL Standard 2034, home carbon monoxide detectors must sound a warning before carbon monoxide levels reach 100 parts per million over 90 minutes, 200 parts per million over 35 minutes or 400 parts per million over 15 minutes. The standard requires the alarm must sound before an average, heathy adult begins to experience symptoms of carbon monoxide poisoning. The warning provides time to evacuate the premises.

I am renting a 1970s trailer, and my landlord says he replaced some parts of my furnace, but I'm still terrified to turn it on. How do I know if I am safe? I looked it up online and was told to check to see if animals live inside or anything, but I don't even know where to start looking! I have renters insurance, but I'm terrified of fires, and instead went out and purchased some electric heaters but I will not leave them on when I am not home, and I live in mountains in new york. The warmest its been is about 40, and everywhere says it should be at least 50 in my house so my pipes don't freeze!


Answer
Turn off all power to anything that sparks before trying to start it, and open the windows.

But think about getting a carbon monoxide and explosive gas detector http://www.amazon.com/Kidde-KN-COEG-3-Nighthawk-Monoxide-Explosive/dp/B0002EVNJ6/ref=sr_1_5?s=hi&ie=UTF8&qid=1353445241&sr=1-5&keywords=gas+detector , that one just plugs into an outlet. It's a great idea to have one, more and more municipalities are requiring CO detectors, and why not get the additional benefit of testing for explosive gas?

carbon monoxide detector?

Q. My carbon monoxide detector alarm keeps going off but i don't wanna get the fire department involved if it is nothing...i've tried cleaning it....moving it around the house to different locations and replacing the batteries with new ones...it stays off for 5 min at each new location and then goes off again...I live in a medium sized house, all the window etc are open...the central air hasn't been on since last night...I do smoke but, I'm pretty sure that has nothing to do with it?? cuz i've always smoked....my cats are acting normal as is my bird? what do you think?


Answer
Call the fire department. They won't mind. They would rather come out on a nothing call like that, than pick up dead bodies. I did the same thing and they said it was not a problem.

Everytime my mother cooks using the stove, the carbon monoxide detector goes off. It seems like every sunday when she cooks for a long period of time faithfully the detector goes off like an hour after the stove has been shut off. I take it down remove the battery and open the windows. about 20 minutes later i put it back up....no alarm goes off. the battery is new so that shouldnt be an issue. The only thing i am fearing is a possible gas leak. What should i do?


Answer
It could be a couple of things.
How old is the detector? They have a sensor that only lasts so long and they should be replaced every 5 years.
If your mother is cooking with gas is there an exhaust fan that removes the air to the outside of the house? If not it could be caused by the recirculation of the combustion air back into the flames.
A good flame should also be a light blue, if it is a lazy yellow flame then there isn't enough primary air (air that is mixed with the gas before combustion) if that is the case then you should ask someone who knows how to adjust it and they should also check for soot which may be evidence of flame impingement.
Gas, like electricity, it is safe if done properly but can be very dangerous if done wrong and Carbon monoxide is very dangerous and any warnings should not be ignored.
