Carbon Monoxide Detectors?

RoRo

I live in a 2 story home and I was wondering where you were supposed to or the most ideal place is to put a carbon monoxide detector? I currently have it in the basement but I'm afraid that if it starts going off we may not hear it on the 2nd floor.

Answer
They should be mounted near bedrooms and living areas. It is recommended you install one on each floor.It is not recommended that you install them in garages, kitchens or furnace rooms. Installation in these areas could lead to nuisance alarms and may expose the sensor to substances that could damage the unit or contaminate it or may not be heard by persons in the home. Read this from the manual.I have mine plugged into a receptacle about 12 to 16 in. from the floor. BTW: The one I have plugged into the receptacle does have a battery backup,they all do in case the power goes out.

Where do you install your CO Carbon Monoxide detector?

simon l

Looking for best location, cheers, links/evidence please.

Answer
Generally the installation instructions supplied with such a device will give the proper locations for these devices.As a general rule they need to be located in the vicinity of the possible source of CO as against smoke detectors which are generally in stair wells and similar locations. EDIT The detector should be mounted in the same room as the appliance
Be at least 1.5mtr from the floor but be above the top of any opening windows
At least 1.85 mtrs from the appliance
Kept away from excessively dusty,dirty or greasy areas such as garages kitchens and boiler and utility rooms
Kept out of damp and humid areas such as a bathroom
It should not be installed in turbulant air from a ceiling fan or dead air spaces such as the tops of vaulted ceilings or gable type roofs, anywhere near fresh air vents doors or windows the access outside. Temperatures more than 38C or less than 4.5C. Behind furniture or curtains or flat on a surface such as a table top
So thanks for the thumbs down know all.

New carbon monoxide detector law?

ChasesM

What is the new law for carbon monoxide detectors? We rent an apartment. Are the landlords required to provide them? What about smoke detectors? We live on the second story 2 bedroom apartment with one smoke detector.
We live in Jamestown, NY.
Or does anyone know a website were I can find the info?

Answer
âIn the case of a building constructed on or after January 1, 2008, a carbon monoxide alarm shall be installed in each of the following locations:

â1. Within each dwelling unit or sleeping unit, on each story having a sleeping area.

â2. Within each dwelling unit or sleeping unit, on each story where a carbon monoxide source is located.

âOne carbon monoxide alarm installed on a story of a dwelling unit or sleeping unit having both a sleeping area and a carbon monoxide source shall suffice for that story within that dwelling unit or sleeping unit.

âIn the case of a building constructed before January 1, 2008, a carbon monoxide alarm shall be installed in each of the following locations:

â1. Within each dwelling unit or sleeping unit, on the lowest story having a sleeping area.

Smoke Detectors Question?

kasmira25

I just moved into a whole house and have noticed that there is one non working old as dirt smoke detector in the kitchen and non anywhere else in the house.

How many smoke detectors do i need?
I live in upstate NY
The house has a full unfinished basement, first floor,second floor with 4 bedrooms and bathroom, unfinished attic.
Gas heat and stove- so do i need a carbon monoxide detector?
I have two small children
The house is not new, its an older victorian

Any info would be helpful as to the amount and placement!! Thank you!

Answer
Not sure what the laws are regarding them, but I will give you best practices.

There should be at least one smoke detector and one carbon monoxide detector on each level of the home.

Each bedroom should have it's own smoke detector, preferably near the door to catch any smoke entering from the hallway.

Don't put a smoke detector in the kitchen due to nuisance alarms, but it's a good idea to have one nearby.

So I would recommend 8 smoke alarms and 3 CO detectors. If you want you can substitute 3 CO/smoke combo detectors.

Put one in each bedroom, one in the main hall on the second floor, two on the main floor, and one or two in the basement depending how big it is.

Oven left on 4 hours w/ food - health risks?

David

This morning, my wife and I woke up with tremendous headaches, and there was an awful smell. We live upstairs, so the smell was the worst up there. Come to find out, my older brother (lives with us) left the oven on with a pizza in it... For FOUR HOURS. He got home drunk, put it in, and fell asleep.

Most concerning is the fact that our 7 mo. old has been super cranky today. My wife tells me that it has been quite the pain trying to get our baby to calm down. We have passed it off as teething or ear aches. Which is possible. But I imagine if we have crazy bad headaches, it has to be worse for her. She screams when given toys, teething toys, held (90% of the time, if she is held, she won't cry), and has been hard to put down for a nap.

My question is - Can there be health risks to scorching a pizza in an electric oven for four hours? Carbon monoxide? Dioxide?

Answer
Well. let's take worst case scenario. If you completely burn a 1lb pizza made of pure starch in an oven and converted ALL the carbon in that pizza to carbon monoxide (which is worse for you than CO2) you would have this much CO produced

1lb x (453.54g / lb) x (1starch unit / 162g) x (6 CO / 1starch unit) = 16 moles of CO molecules.

***********
according to this MSDS for CO
http://www.mathesongas.com/pdfs/msds/MAT04290.pdf
the LC-50 for a rat via inhalation (ie.. the concentration and time to kill 50% of a test population of rats) = 1800ppm for 4 hours.

Now rats aren't people, but usually that toxicology data is within an order of magnitude of people. So lets just say.. 1000ppm for 4 hours is going to give a major headache!

************
for every 1000 ftÂ² of living space.. assuming you have 8ft ceilings.. and assuming the temp is about 25Â°C, so that density of air = 1.2 g / dmÂ³.. you have this much air at any point in time.

(1000 ftÂ² x 8ft) x (12 in / ft)Â³ x (2.54cm / 1in)Â³ x (1 dm / 10cm)Â³ x (1.2g / dmÂ³) x (1 mole / 29g) = 9.4 moles of air

so you can easily see the CO could displace all the air giving you >>1000ppm of CO for 4 hours.

*********
*********
now.. That's probably not what happened. You still still have some pizza charcoal left. Part of that pizza was water. Water is just vaporized.. The sauce contains water, the cheese contains moisture, whatever else. You have a vent over your stove. to allow some of the gases to escape. You have a HVAC system moving air around your house. Houses aren't airtight. etc. And usually only a small fraction of combustion goes to CO instead of CO2.

And of course, if you have a gas oven, that could produce CO.. And I'd guess you've run your oven for 4 hours before without getting sick (albeit without vaporizng your food right?)

So instead of 100% CO in your atmosphere, you have had 1000ppm.. who knows? It's certainly possible, you were CO poisoned by this fiasco. (btw.. a carbon monoxide detector would have detected this!).

Regardless. This is your health on the line. If you still have headaches after reading my answer here and if your child is still uncomfortable, get fresh air and seek medical attention immediately.

What could cause both my mother and me to have nausea, dizziness, chills, and headaches?

Sean C

It started on New Year's Eve when I had a terrible migraine. (And no, alcohol was not involved.) I ended up going to bed that night at 9:00 because the room was spinning and I was very nauseous. I had a hard time sleeping because anytime I moved I thought I was going to be sick. And then in the middle of the night, I had (sorry if this is too much info) bad diarrhea. But what was most strange, my mother suffered the EXACT symptoms that night - she in her bedroom, me in mine. So initially I thought carbon monoxide. But that can't be; we have carbon monoxide detectors in every room, including the basement. And we felt fine all day.

I was fine for a few days until last night, when the SAME thing happened to me. I had migraines, dizziness, (diarrhea), nausea, and the chills. But my mother was fine. But tonight, my mother now has it again but I don't.

Now, we're both fine during the day. What's up??? Now I read that the symptoms are signs of pregnancy. Impossible: my mother's almost 50 and I'm a 21 year-old male.

I was just wondering if anyone has any idea what the cause could be. Thanks!

Answer
Diarrhea is caused by a virus . Sounds like a stomach virus or flu. Drink Gatorade to replenish the electrolytes you are loosing every time you go to the bathroom so you don't dehydrate. Try the BRAT diet ( Bananas, Rice ,Apples & Tea) its great for stopping diarrhea naturally without any meds. You might want to stick with drinking only out of 1 personal glass so as not to spread the germs back and forth. Hope you both feel better soon.

carbon monoxide?

Hey its Da

about a month ago 2 of my carbon monoxide detectors went of during the middle of the night, but my parents did nothing about it because they said that the detectors were cheap. So about about 2 weeks later i encouraged them to buy better detectors. So my parents bought 2 of the most expensive detectors they could buy. but to be surprised over the night after they were plugged in and everything they both went of and once again my parents think its just a coincidence. i think in total its been like 6 or 7 times they have gone off what should i do or who should i call
i appreciate any help

Answer
Usually you can call your local Fire Station..use thier NON EMERGENCY phone number..and they will come out and check this for you with thier meters..call them and see..and if you have gas in your house for heat/cooking etc..the local gas company may also come out for free and test the air..They usually will when it concerns carbon monoxide and they have thier service there

Why is my carbon monoxide detector chirping?

John

Started Monday night at around 4am. Not an 'alarm,' but just a chirp as though the batteries were low. I hit the reset button and it stopped immediately. Same thing happened Tuesday night. Hit reset, stopped doing it.

Yesterday it started chirping in the middle of the afternoon, so I installed a new 9v battery, thinking that it must be low. Apparently that wasn't the problem, though, because it started chirping again this morning.

Does anyone have any ideas?
*edit: I replaced the battery yesterday with a new one, assuming the battery was the problem and that it would fix it.

Answer
Hi John, Iâm Ken with The Home Depot and have had this question before. Since you have replaced the old battery with a new one and that is not problem, your unit is probably ready to be replaced.

Some manufactures say to replace your alarm every 5 to 7 years. This is to benefit from new technology.

So I would check the age of your alarm and if it is within this time frame I would consider getting a new one. Having a proper working carbon monoxide alarm is very important. Hope this helps.

Why does my Nighthawk carbon monoxide detector keep chirping every so often and reading 248 after I reset it?

Dragonlady

The last few days, the detector has chirped...does it for about an hour or less, every 30 seconds or so. Sometimes it stops for hours..even up to a day before it does it again. I've changed the battery twice. It came up low battery once...but was reading 0 the whole time the other times it happened. Then when I hit reset, it went to 888, then to 248 and once said 247. I don't understand this...makes me worry, yet it goes back to 0.

Answer
It suggests that there most likely is a malfunction if as you say that you've put new batteries in. It could also be an end of life warning (not yours, the carbon monoxide detectors'). If you've had the alarm for between 4-7 years this could be the case. People have had some problems with this particular model of carbon monoxide detector. It's probably best to contact the manufacturer directly, in this case Kidde, and if you have a valid warranty get them to send a new one asap. If not and your detector is in the end of life period it's probably better to buy a new one asap anyway. In the meantime it's better not to take any risks; make sure your house is well ventilated at all times.

Worried about Carbon Monoxide.?

Worried about Carbon Monoxide.

Okay so the carbon manoxide dector went off. It was showing there was 400ppm, after it stopped beeping for a few min. I checked the memory, and it said the max ppm was 0ppm. I replaced the batteries since I thought it could be the batteries could have gone bacd. But when I checked the amount of juice left in the batteries it was still pretty much fully charged. So I put the new batteries in and it's been about 2 days ago and the detector hasn't gone off since. So was it was just a false alarm? It's not even showing a reading above 0 ppm.

Sadly there's no way to get it checked out or my parents will get pissed at me...

Answer
Carbon Monoxide levels could have risen temporarily and then fallen back to 0 ppm. I cannot see any other explanation. Notify your parents that the alarm went off and they can either replace it or get it checked out by a professional.

I have a gas water heater outside - do I need a carbon monoxide detector?

Carol L

Answer
When you are burning indoors any type of liquid or solid fuel for heating, cooking or other use, you should have an active carbon monoxide detector installed in your home.

If you have fuel-burning appliances on more than one level of your home, you should have a carbon monoxide detector on each floor. For example, if you have a gas range on the main floor and a wood-burning fireplace on the lower level, you should have detectors on each of these floors.

Such fuel-burning appliances are generally tested and safe to use, but should there be a clogged vent line or any part of the appliance that becomes faulty, it could release hazardous levels of carbon monoxide in your home and death can occur within minutes. But you can keep your family safe by using a carbon monoxide detector which can alert you to the presence of this silent toxic gas.

If you work regularly on running vehicles in a closed garage, you should also consider installing a unit in that area.

What are the physical effects of carbon monoxide poisoning before death?

confused i

After the body was removed from the vehicle there was blood present in & on the side of the vehicle, and drops of blood on the ground. Why would blood be present from carbon monoxide poisoning? Also, by running a hose from the tailpipe through the window of the vehicle and sealing the window, how long would it take for death?
Would the person be able to turn the key off but not able to open the door? The vehicle was turned off but the doors were locked when the person was found. Could they have decided not to go thru with it, had the mobility to turn off the car and not had enough mobility to open the door?
This was an apparent suicide but there wasn't a note found and I have alot of questions. The presence of blood, the key turned off, the doors locked?......all of these things really puzzle me.

Answer
CARBON MONOXIDE POISONING

THE FACTS

As colorless as the air, this sudden killer is responsible for 700 fatalities a year in the United States. Carbon Monoxide (CO) is not to be confused with Carbon Dioxide (CO2), which is responsible for the bubbles in your gingerale. CO is a product of inefficiently burnt fuels that are created by an appliance or heating unit in the home. One in five deaths by CO poisoning can be attributed to a malfunctioning appliance, either due to poor maintenance or a design fault. Carbon Monoxide is the inevitable by-product of the burning of all carbon based fuels, and the less of it that is in the air, the better.

CO is deadly because it is not detectable to the five human senses. To confuse matters more, symptoms of CO poisoning mimic common every day ailments such as migraine headaches or the flu. This insidious threat to home safety is responsible for 113,333 emergency situations in the U.S. every year. There are two basic types of carbon monoxide poisoning, ACUTE and CHRONIC.

SYMPTOMS AND DIAGNOSIS

ACUTE CO poisoning is rarely detected until its victims become quite ill. In this kind of scenario, a heating unit or appliance breaks down and emits lethal levels of gas in a short time. The severity of the symptoms varies depending on the concentration of the gas in the air. The chart below gives you an idea of when to suspect that CO is the culprit behind your discomfort.

The numbers below represent the concentration or amount of CO that is in the air as per parts per million (ppm) followed by its physical effects:

* At 35 ppm - No adverse effects until after about 8 hours of exposure
* At 200 ppm - Mild headache after 2-3 hours of exposure
* At 800 ppm - Headache, nausea and dizziness at 45 minutes. Physical collapse at 2 hours.
* At 1000 ppm - Loss of consciousness at 1 hour.
* At 3200 ppm - Dizziness and nausea at10 minutes. Loss of consciousness occurs at 30 minutes.
* 12,800 ppm - Collapse, loss of consciousness and death after 1-3 minutes of exposure.

CHRONIC CO poisoning can be difficult to diagnose as the symptoms of long-term exposure mimic common disorder such as the flu. Long-term exposure to smaller amounts of CO has been associated with diabetes and brain damage. There is a middle range of slightly higher exposure over a shorter period of time. In this scenario, a gas heater breaks down and an entire family can suffer nausea and dizziness over a period of two weeks indicating that it might be from CO leak.

Persistent symptoms of CO poisoning include

* Fatigue
* Dizziness
* Nausea
* Vomiting
* Confusion
* Convulsions
* Respiratory problems
* Rapid breathing
* Persistent cough
* Concentration problems
* Hallucinations
* Panic attacks
* Clumsiness
* Severe muscle pains
* Trembling
* Vision problems

CAN IT BE PREVENTED?

CO takes its victims by surprise so poisoning is as hard to predict as any act of fate. However, there are measures you can take to immediately allay the severity of the situation.

* First and foremost, outfit your home and garage with a CO detector. Human beings are unable to smell CO so these devices act as a second nose. These devices resemble a fire alarm and sound off at the first subtle whiff of gas.
* Have a qualified professional regularly check your heating systems, chimneys, furnaces, stoves and cookers for flaws, leaks, efficiency and structural weaknesses.
* Be mindful and observant. For example, if you suspect your furnace is not working, don't use it until it is fixed.
* Be a savvy consumer. Before purchasing a major appliance, check with the manufacturer or a consumer safety groups to see if the brand has a good reputation.

PREPARATION

Carbon monoxide poisoning is accidental, and you should prepare for it just as you would any other catastrophe that might strike without warning. As is the case with fires, it is a good idea to make sure that all doors windows and exits are kept free of obstacles. Keeping a window open, while using appliances such as tabletop gas cookers is also a good idea.

WHAT TO DO IF THE UNFORTUNATE OCCURS

If at any time you feel you have been exposed to dangerous carbon monoxide fumes you should remove yourself from the area immediately and seek medical assistance. In this case, it is also advisable to open doors and break windows to let fresh air in and speed evacuation.

Emergency treatment for acute CO poisoning almost always includes keeping the victim warm as well as dosing them with supplemental oxygen via a mask.

I would like to attach garage 24' x 26'8" to house. Need help with how to information.?

carrie

Answer
Well, if the garage is built, already, then you just need to put a gangway to it...

You can build a box enclosure from the door way, (man door, they call it), to the side of your house and if you dont have a door, install one where it will meet the house in a conspicious spot, of course, (a hallway, or off to a major room like kitchen, mudroom or dining room). Do not have it ending in some ones bedroom, or livingroom, or go through the laundry room, (if you have to bring groceries, you dont want to have to bump against a lot of different things).

Now, DO get a carbon monoxide detector! Because if some one is working in the Garage, you DONT want to die, if they leave the car on!

Make SURE your insurance is contacted, because it will cost you "more" for coverage, and it may negate the coverage you have now, if you dont tell them, and something happens where it burns the house and garage down.

Have extra fire extinguishers in the garage and outside the gangway that is going to lead to the garage...

Other than that, some 2X4s, and concrete for a pad, leading from garage to house, and insulation to keep it warm, or at least fromt the wind... and you will have it..

Also, check with local building codes from your Municipal or City or Country Building Inspector and see if you are "allowed" to do this! And if you live in a "housing project", (Condominiums), with a local Housing Authority, then you may not be able to do this due to regulations, governiing the placements of certain conditions that must be adhered to...

I wish you well..

What is the maximum occupancy declared by the Tompkins County (Ithaca NY) housing standard?

Kevin

I live in an old house ( built late 1800's) with 6 bedrooms, 2 bathrooms, and 1 kitchen. I would like to know what the maximum occupancy is for this house. I am renting a room like most of the other tenants. The house is in Dryden NY which is part of Tompkins county (Ithaca NY). We have been having some minor issues with the landlord and I would like to know if this many of us are even legally permitted to live in a single house. I would also really like to have some links to any information regarding the fire safety regulations. There are no smoke detectors in any of our bedrooms, and maybe not on the second floor at all, a single fire extinguisher which is still in its box under the sink, and I don't think any carbon monoxide detectors. We have a big cast iron coal stove in the kitchen that heats the house. There is also a water treatment center in the basement that takes the sulfur and what not out of our well water but it is not in working condition. Any answers and links to places where I can find answer would be greatly appreciated. Thank you. =D

Answer
" There are no smoke detectors in any of our bedrooms"

Smoke detectors do not go IN the room, they go outside the room in the hallway.

" maybe not on the second floor at all"

You need to look. Smoke detectors pretty much all look alike with only minor variations (an emergency light if the power goes out, size).

", and I don't think any carbon monoxide detectors. We have a big cast iron coal stove in the kitchen"

This IS a problem. Contact your local Fire Department or Board of Health.

"a single fire extinguisher which is still in its box under the sink"

Fire extinguishers are not usually required and not anywhere other than the itchen (grease fires). They don't want you trying to battle the fire, they want you to get out and call the fire department.

"There is also a water treatment center in the basement that takes the sulfur and what not out of our well water but it is not in working condition. "

Water quality is not controlled beyond certain thiings. Just because it stinks does not make it non-potable.

Alert from Carbon Monoxide alarm?

I've had my alarm for 2 years. But it has just given me an alert saying the levels are at 35ppm. I believe this is the lowest level threshold for an alert so I'm wondering whether I should get this checked out? I have already aired out the house by opening the windows. It gave a similar low level alert 6 months ago where I similarly aired out the house. The recent alert is only the 2nd time it's happened. Should I call in a specialist to get it checked out or is it such a low level that simply airing out the house be sufficient?

Answer
Definitely change the battery. If it keeps going off call 911 and have them send the fire department. They will come out with a gas meter and be able to determine if it is a false alarm or not.

Why does my Nighthawk carbon monoxide detector keep chirping every so often and reading 248 after I reset it?

Dragonlady

Why dose my carbon monoxide detector goes off when there are no CO2 levels present?

Native New

For some reason the CO2 alarm keeps going off. I know the stove tops are off, and the 9V battery that powers it, have not gone down to levels that will make the CO2 alarm "chirp" once a minute.

But for the last 2 weeks my CO2 alarm keep going off at all hours of the day or night. Even when I'm not home.

Can someone PLEASE HELP!!!

Thank You in advance.
I checked the date on it, it with was manufactured in December 2004.
The batteries are brand new. They were changed last month.

Answer
Most carbon monoxide detectors use a chemical reaction to measure levels. When they get old they can malfunction. Check the manufacture date on yours and see if it needs replaced. For more info, check out the furnace page at my source. It will give you more info about co sources and what to do.

How long does it take for carbon monoxide to kill you?

blah

This morning the carbon monoxide alarm went off in our house. My dad called the fire department, they came and checked and said everything seemed okay and said we could go back in our house. My sister and I are still a little freaked out, and my 10 year old sister is scared to go to sleep because my brother told her carbon monoxide kills you in your sleep. He also said the fire department didn't even check for carbon monoxide because they didn't take any machines or anything in the house. I think he's just trying to scare my sister and I but I'm still a little freaked out. This happened this morning at about 11:30am, and now it's 6:40pm. Would we be dead already if there was carbon monoxide in the house? Or what?
Stupid question, sorry lol, my brother is just freaking me out a little.

Answer
Don't let him get to you. Sometimes the detector could go off just because the battery.

Often people who have a mild to moderate problem will find they feel sick while they spend time at home. They might feel a little better outside in the fresh air but will have re-occurring symptoms shortly after returning home. If other members of the family have re-occurring bouts with flu-like symptoms while fuel-burning appliances are being used it may be time to have the house checked by a professional.
Symptoms of Carbon Monoxide Poisoning
Low levels of carbon monoxide poisoning can be confused with flu symptoms, food poisoning or other illnesses and carry a long-term health risk if left unattended. Some of the symptoms are:

Shortness of breath
Mild nausea
Mild headaches
Moderate levels of CO exposure can cause death if the following symptoms persist for a long measure of time.

Headaches
Dizziness
Nausea
Light-headedness
High levels of CO can be fatal causing death within minutes.

Treatment Options
There are immediate measures you can take to help those suffering from carbon monoxide poisoning.

Get the victim into fresh air immediately.
If you can not get the people out of the house, open all windows and doors immediately. Any combustion appliances should be turned off.
Take those who were subjected to carbon monoxide to a hospital emergency room as quickly as possible. A simple blood test will be able to determine if carbon monoxide poisoning has occurred.

No smoke or carbon monoxide detectors in apartment, what should I do?

Ava

I just moved into an apartment in Chicago. It is an old building with a gas stove and gas heating. This afternoon I came home and noticed a strong gas smell, so I switched off the gas to the stove, opened all the windows and turned on a box fan to draw in outside air. I noticed the pilot lights on the stove had switched off. The landlord said the smell was because the pilot lights were off and he relit them. When he relit them one was burning orange instead of blue and there was still a smell so I've switched the gas off again.

I've had a look around the apartment and can't see any smoke alarm or CO detector. Is this illegal in Illinois?

Is there someone who can test levels of gas and CO in my apartment, preferably for free?

And, right now I have all the windows open and the fan going, and the gas to the stove is switched off. I should be okay to sleep in here, right?

Answer
Smoke alarms are required by law (typically hard wired or powered by a 10 year lithium battery). I suggest you point it out to your landlord first but if he doesn't act immediately call your local fire marshal to come inspect your apartment and to bring his citation pad. He might also be able to help with the stove issues.

Co2 detectors are not required by law but could be a life saving $30 expense you can take from one apartment to the next..

Is it normal for a carbon monoxide detector to read 0 ppm?

dfjkdfj

I got a carbon monoxide detector, which reads 0 ppm. It has a feature that allows you to check the highest level within the past 24 hours, which also is 0 ppm. Is this normal? I thought there might be one or two ppm in the house.

Answer
It can read it. But f you want to know if it is working then it will either need to be calibrated by a professional (cheaper to buy a new one), or quick gut check take it to the hood of an 80% gas HW heater. It should give you some reading and I usually see above 9 when around a water heater.

Carbon Monoxide Detector - Peak Level Reading Question?

Alex

I have the Kidde KN-COPP-3 detector and I'm having a little trouble figuring out how it's operating.

So far I have not had any alarms go off, and I always get a reading of zero. However, today when I came home I had the "Err" error message displayed, and when I tested the Peak Level Memory it came up as "999." When I test now, however, the unit is reading "0".

How can it be possible that I have had a 999ppm reading and the alarm never went off? Could this be due to the error that was displayed today? The unit was safely plugged in when I checked, my only guess for what might have happened was a brief power surge/outage but my neighbors are saying they didn't have anything of that sort.

Just concerned and wondering what this machine is trying to tell me. I'm looking for a customer service number so I can check it myself.

(For reference, I'm not currently nor have I recently experienced any symptoms of C.O. poisoning, but for safety's sake I've opened my windows and done several Tests on the unit.)

Answer
Check you peak reading often, but 999 would be so lethal. I've heard anything more then 100 for a few minutes can be fatal. Most likely it was apart of your err. message. Mine reads a peak sometimes around 16, but the only time i've seen err or high numbers is when the battery is dead, and changing the battery/resetting the unit.

Is California's highest in the nation unemployment related to its highest in the nation taxburden?

Tesla V

@Eric, I am not saying it is the rich. It is the high taxes killing jobs in California.

Answer
The unemployment rate is tied to the business climate-taxes are only part of that.

Another part is the amount of crap you have to go through to get anything done in this state. It always seems to require 42 state agencies, any one of which can say no for any reason (or for no reason).

Here's one example--I basically can no longer use my fireplace because of "bad air quality". By any actual measure, the air quality is better than it was 10, 20 or 30 years ago, but they've redefined "bad air quality" so that many more days fall into that category.

And because I have a fireplace (which I'm not allowed to use), I'm legally required to have a carbon monoxide detector in my home, in case the fire that I'm not allowed to burn causes a carbon monoxide build up. The most recent data I ran across in a short search is from 1979-1988 (when you could use your fireplace basically every day if you wanted), where it showed that non-vehicle carbon monoxide inhalation caused 270 deaths. Not per year--for the entire decade.

Nearly 1/4 of those occured in cabins or tents (where people might do something like run a kerosene heater or stove to keep warm, and didn't properly vent it). So because an average of 21 people per year died in houses from carbon monoxide (that's .00009% of the state population at the time), I'm legally required to install and test a carbon monoxide detector-in fact, I could not legally sell the house without one, and I couldn't have any sort of construction done (even something like an electric water heater our in the garage). I'm not saying it's a bad idea to have one, but to legally require it!? That's just asinine.

Is my paranoia of heaters useless?

Hal

It's pretty cold for California right now (46Â° degrees) and my family has the heaters on. I turned the heater off in my room and kept the windows open. I'm EXTREMELY warm still, I have bundled myself up in warm clothes and blankets... I simply can't stand the idea of breathing in carbon monoxide. Or suffocating from it. I also need to breathe cool air in order to sleep (even if I'm bundled). The idea of breathing warm air.. bothers me.

Is this completely stupid?

Answer
I don't know if I would call it useful, but I certainly wouldn't call it stupid! Carbon monoxide is odorless and colorless, and defective heaters and carbon monoxide poisoning do kill people every year. It's like being afraid of sharks. Which I am. So I don't swim in the ocean.

There's a couple of things that might help. You can get a good carbon monoxide detector at Home Depot for about $30. This would absolutely protect you. Or get an electric heater. Electric heaters don't produce carbon monoxide.

The chance of dying from a heater/carbon monoxide accident in your lifetime is 1 in 1,500,000.
The possibility of dying from a snake bite or bee sting during your lifetime is 1 in 100,000.
The chance of dying in a car accident in your lifetime is 1 in 80.

And sharks? 1 in 11 million. Yes, that's the highest odds here ... but it doesn't stop my phobia. But it's just a phobia, I don't feel any urge to swim in the ocean, and I'm perfectly healthy and happy otherwise. It's not a big deal.

You may not change this, even with the statistics, even with a CO detector, or an electric heater. Does it matter? No, not if you're not putting yourself in harm's way. Bundling is perfectly fine. Breathing cold air is perfectly fine. Or leave your door open so a little bit of the heat in the rest of the house can drift in -- it won't be too warm, but you won't be shivering either.

be well!

Where can i buy a CO detector?

carbon monoxide exposure?

Phillipa C

I have been on a house boat for 3 days and didn't realize until today that my carbon monoxide detector was reading from 36-62 ppm. Will I suffer any sort of brain damage from longish exposure to small amounts?

Answer
The problem with carbon monoxide is that it competes with oxygen for a place on haemoglobin molecules (inside red blood cells). Since your body needs oxygen, not carbon monoxide, if the latter takes the place of oxygen, the body can become hypoxic (short of oxygen).

Matters are made worse by the unfortunate coincidence that carbon monoxide binds with about 250 times the tenacity as oxygen, which means that it often takes a long time (hours to days) before all of it is eventually replaced by an oxygen molecule again. But eventually it is, and things return to normal.

The point is: now that you're off the house boat, you are over the worst. If you are feeling fine now, you will stay fine. This is not one of those conditions where you take a hit now, and it whacks you suddenly months or years later! So don't worry... but look into fixing the problem on the house boat!

Hope that helps!

carbon monoxide detector keeps beeping?

KillingMot

I have two carbon monoxide detector. My upstair carbon monoxide detector keeps beeping every 2-4 minutes. It also has a number saying 52. The carbon monoxide downstair appears to be fine, althrough it doesnt have that displaying number thing. I tried switching the carbon monoxide with each other, and now neither beeps anymore. But one of the carbon monoxide detetor(the one from upstair then switch to downstair) still says 52. Should i be concern?

Answer
Although all home detectors use an audible alarm signal as the primary indicator, some versions also offer a digital readout of the CO concentration, in parts per million. Typically, they can display both the current reading and a peak reading from memory of the highest level measured over a period of time. These advanced models cost somewhat more but are otherwise similar to the basic models.

The digital models offer the advantage of being able to observe levels that are below the alarm threshold, learn about levels that may have occurred during an absence, and assess the degree of hazard if the alarm sounds. They may also aid emergency responders in evaluating the level of past or ongoing exposure or danger.

The alarm points on carbon monoxide detectors are not a simple alarm level as in smoke detectors but are a concentration-time function. At lower concentrations (eg 100 parts per million) the detector will not sound an alarm for many tens of minutes. At 400 parts per million (PPM), the alarm will sound within a few minutes. This concentration-time function is intended to mimic the uptake of carbon monoxide in the body while also preventing false alarms due to relatively common sources of carbon monoxide such as cigarette smoke.

CONCLUSION: YOU ARE SAFE AT 52.

Carbon Monoxide Detector upstairs, i live downstairs?

Donavon

i have a gas heater i put in my room last night. im worried im gonna get carbon monoxide poisoning. we have a detector, but its all the way upstairs, and i live downstairs. if its coming from my heater in my room, wouldnt it effect me before it reached the detector upstairs?

Answer
Carbon monoxide is heavier than air. The detector should be placed near ground level on the lowest occupied floor of the house. It's good to have one per floor, but if you only have one, it should be at the lowest occupied level because that is where the highest concentrations of gas will pool -- and you want the earliest warning possible. It should be near the floor for the same reason. If the heater is in your room, the detector should be in the room or the adjacent hallway. There are combination smoke/CO detectors but smoke detectors need to be near the ceiling and CO detectors need to be near the floor. Combination detectors are most appropriate for staircase landings, etc. in between floors of larger houses.

carbon monoxide detectors?

Prevaricat

My CO monitor beeps randomly from time to time. Is this normal? I assume that if I did have a CO problem, it wouold beep like crazy. As is, it beeps only a few times every now and then. Should I be concerned?

Answer
1) You may have a battery issue. All detectors that operate on batteries or have battery back-up will CHIRP occasionally to remind you that the battery needs to be replaced. The battery may be low on voltage or it no longer can take a "load' to operate the device.

2) You my have a dirty detector. Sometimes the CHIRPING may continue even after replacing the battery. Use a vacuum cleaner to suck out the dust that accumulates over time. Take your time and do a thorough job.

3) You my have a bad detector. Smoke and CO detectors do not last forever. They should be replaced if 10 years old or more.

Note: Smoke and CO detector batteries should be replaced at least once a year. Don't get into a lazy habit of waiting until it CHIRPS to replace it. A good rule of thumb is to replace all detector & alarm batteries when the clocks are changed for Day Light Saving Time.

Always use name brand Alkali batteries, bargain batteries are not a good idea in this application.

All detectors & alarms are designed with "smart" technology. Listen to what they're telling you and don't ignore the warning signals. They can't save your life if they're not working.

Math Word Problems Help?

natj429

Hi, i can't seem to understand how to get the equation for these assignments. The answers are in the back of the book but my answer is never the same. I Hope you can explain the process for me. Here are the problems:

1. A riverfront boat storage area is rectangular with fencing on all sides except the side along the river. If 550m of fencing is used and the side along the river is 50m shorter than the two longer sides, find the dimensions of the site. ANSWER: 150m by 200m

2. One laptop computer has 5.5 times the storage capacity of another. Together they can store 65 Gbytes of information. What is the storage capacity of each laptop computer? ANSWER: 10 Gbytes and 55 Gbytes

3. The online cost for an in-home smoke detector and carbon monoxide alarm is $4.29 more than twice the cost of a leading competitor's unit. If the two units are purchased together, their combined cost is $87.36. What is the cost of the more expensive alarm? ANSWER: $59.67
I would appreciate a step by step on how you reached the answer. Thanks

Answer
Question 1:

3 sides of a fence which create a rectangle

x = the longer side (two of these)
x - 50 = the shorter side (one of these; the other is the river)

Total fencing used on the 3 sides that have fencing: 550

x + x + (x-50) = 550
3x - 50 = 550
3x = 600
x = 200
y = 200 -x = 150

x = Longer side of fence = 200
x - 50 = shorter side of fence = 200 - 50 = 150

Dimensions = 150m x 200m

Question 2:

x = computer 1
y = computer 2
x = 5.5y

x + y = 65

5.5y + y = 65
6.5y = 65
y = 65/6.5
y = 10

Total = 65
x + 10 = 65
x = 55

Question 3:

Alarm 1 = x
Alarm 2 = y

x = 2y + 4.29
x + y = 87.36

Substitute (2y+4.29) for x in that equation

2y + 4.29 + y = 87.36
3y + 4.29 = 87.36
3y = 83.07
y = 83.07/3
y = 27.69

This is the price of the less expensive one

x = 2y + 4.29
x = (27.69 x 2) + 4.29 = 59.67

The pilot light in my gas furnace goes out every day, is it a health hazard?

Jessica

My landlord refuses to repair the gas furnace, even though the pilot light has been going out on a weekly basis for all the 8 months I have been his tenant. The only thing he has done so far is (last week) to get a plumber to install a new ignotion switch. (Previously, it was having to be relit with a long match as the switch was broken.)

Putting a new switch on only makes it easier to relight, it doesn't solve the problem of why it was going out to begin with. Since this was done 5 days ago, the gas has gone out every day, the last two days it was twice in one day. The ladt time we had to re-light it todsy, it took numetous attempts over about 20 minutes.

I am a NY tenant. We rent a 2 family house with my family on the ground floor. when the gas boiler goes out, it means the tenant upstairs has no hot water either. She told us this has been going on for 4 years, yet does not seem willing to 'rock' the boat.

First question is my highest concern- is this a health hazard to my family and I? I have had a huge increase in migraines and wonder if this is connected.

Can I force my landlord to repair it?

In NY, is the landlord obligated to 1/ install smoke and carbon monocide detectors and 2/ to have the gas boiler (furnace) inspected annually? This is a legal requirement in many European countries.

Thanks so much for any advice or thoughts! All will be greatly appreciated.

Answer
If this is a forced air furnace there is a very important and possibly dangerous situation that hasn't been raised. A cracked heat exchanger will not only keep blowing the pilot out but can cause carbon monoxide buildup.

Relight the pilot and burner and wait for the blower to cycle on.If you see the flame fluttering, or worse yet, if the flame starts moving towards the the front part of the heat exchanger cell shut it off completely and possibly start shopping for a new furnace!

However a severely rusted burner assembly on some brands can cause the same symptoms. Hopefully a good cleaning with a wire brush will cure your problem.

Good luck!

How do I install a hardwired smoke/carbon monoxide detector in my home?

maltesefal

At times, the present detector's alarm sounds for no reason and must be replaced. I'd like to do it myself and avoid the expenses of a professional. I know how to shut off the electricity at the site and have all necessary tools.

Answer
Call an electrician if you mess up the detector will not work this could be very dangerous. It isn't like wiring a light if you mess up a light it just wont work you mess up this and the smoke will fail to sound during a fire.

If you don't know how to do it how do you know you have the tools you need.

********"Hi i am glad to me you" has no clue what he is taking bout there in no positive or negative wiring in a house. Electrical tape is almost never to be used for a permanent connection it will dry out with age and loose it adhesive leave the wire exposed to arcing and become a fire hazard. In the rare case tape is use for a permanent connection(burndies for very large wires in industrial setting) it is a special fat rubber tape that you will not find at home depot a roll is about $10 and an entire roll is used for just one connection making a ball of tape about the size of a baseball

Are Smoke Detectors and Carbon Monoxide Detectors the same thing?

Chris(f)

there has been a lot of deaths in my city cause people got carbon monoxide poisoning so all over the news they're like "go out and buy a carbon monoxide detector!" so I went to my Wal Mart and I didn't find any. I found a bunch of smoke detectors but I already have 1 installed in my home, and then it dawned on me...maybe it's the same thing! Well is it?
if they're not the same thing, where can I buy one?
I checked Wal Mart, Target, Home Depot and some hardware shops

Answer
No Carbon monoxide detectors are not usually combined with smoke detectors also the placement of carbon monoxide detectors are crucial you. Usually you can find the kind that plugs into a outlet and you want it near a supply vent.

You can also usually go to the local fire dept and inquire about carbon monoxide detectors. Around here they usually give them out free.

We offer free carbon monoxide detectors with every furnace install. Also it is something I suggest for every furnace PM I do the cost is about $25.00 to $40.00 depending on the one the customer wants.

Check Johnstone or another HVAC supply house if you cant find one at Wal Mart, Home Depot, or Lowes.

Carbon Monoxide!?!?!?

Elizabeth

I need a list of all the places carbon monoxide can leak from in the home, and why it leaks. I overreact I guess but I just want to be safe so I'm worried please help!!!
And yes I have carbon monoxide detectors.

Answer
Carbon monoxide forms when an carbon based fuel (all gas, petrol, fuel, ethanol) doesn't burn with enough oxygen to form carbon dioxide. This happens everytime you use a gas device, because the oxygen is just not concentrated enough in the local area to allow for the fuel to burn completely and leave no carbon monoxide. This is natural and not to worry about.

I imagine you're most likely to be at risk from faulty combustion devices like furnaces, gas fireplaces and heaters and spirit burners. Anything that burns gas and isn't in a well ventilated area (that's why outdoor stoves are fine, the wind just blows the carbon monoxide away) should be checked.
I stress that these products would have had to meet a certain level of quality before being sold to you - and that regular maintanence would avoid any leaks/ build up. If in doubt, consult your local firebrigade - i'm serious, they'd be glad to help, it's their job.

Where is the best place to put my carbon monoxide detector?

Flynn2

I live in a 1100 square foot condo. Living area, 2 small bedrooms downstairs. Upstairs is a master bedroom and master bath only. From the master bedroom upstairs, there is a small door that goes to the attic space. The hot water heater and inside HVAC unit are right next to each other. Nothing else in the house runs on gas at all. There is also an outlet next to the door on the inside.

Should I put the detector right next to the two appliances? Should I put it right outside of the small door or put one downstairs? I'm afraid if I put it in the attic and the CO came through the vents, the detector would be too late.

I would like to have this answered by a HVAC expert or emergency personnel. Thanks.

Answer
Install your carbon monoxide detector according to the specific manufacturers installation instructions that came with it. If you do not have the instructions or cannot find them for your unit, throw it out. Buy a new carbon monoxide detector with complete installation instructions and warranty information. The new co detector will come with the manufacturers placement recommendations for that specific product.

The Ultimate Solution; You can have a commercial alarm company come out and install a full set of fire, smoke, and carbon monoxide units that will be monitored 24/7.

Also, have a licensed Plumbing, HVAC, or Mechanical company inspect your gas appliances at least once a year.

Carbon Monoxide Readings... deadly? Please read!?

KaDy

Hi, My carbon monoxide detector said 11 about an hour ago, The pilot light went out on the gas fireplace. Is 11 bad? I have animals in my house and I want to make sure they are going to be okay. The detector says 0 now.

Answer
The carbon monoxide seems to be coming from the gas fireplace since carbon monoxide is produced by the incomplete burning(combustion) of solid, liquid, and gaseous fuels.If you smoke a couple of cigarettes, or someone had been smoking a cigar in the last hour, you could hit 11ppm CO in your home. Cigarette smokers exhale between 4 and 9 ppm CO all the time. And, if you're in a city, it's possible that the background CO rises to that level during the day. The mechanic's meter might hit 12-15 ppm standing in the middle of your back yard!
Besides, 11-12ppm CO may be ambient conditions and nothing to really worry about. It could also be "left over" output from cooking or some other activity. To make it even more complicated, the cheap CO meters and many residential CO detectors are cross-sensitive to other gasses, like methane, butane, alcohol, aerosols, etc. I've seen "Pam" cooking spray put a CO detector into alarm.
Besides, if you had been cooking, using the oven, heating water on the stove, or had a door or window open that could cause your flue(any duct or passage for air, gas, or the like) to down draft, you might see 5-20ppm in the house for a period of time. An oven will produce anywhere from 20 to 600 ppm when operating. Most run in the 30-100ppm range.

You should still check with the local firedepartment or call the company that made The detector your using.

How do carbon monoxide detectors work?

kyorge6293

I am trying to create a detector to see how much carbon monoxide is in a room. I am looking to find an specific average throughout a day, not just if the carbon monoxide level is too high.
By the way, I am doing a project on Indoor Air Pollution.
Thanks in Advance.

Answer
Most Carbon Monoxide detectors determine the amount of CO present in the air by using an electrolytic sensor. If the value is high, the alarm sounds.

There are digital CO detectors available which will read you the level on an LED number display. You can write down the numbers on the display at predetermined intervals and average them after 24 hours has passed. Most houses should read 0 all of the time. I've only seen mine say something other than 0 when I was working on the car in the garage and had it running for a couple minutes (with the garage door open although still allowed enough into the house to cause it to display, but not alarm). Take a look just past halfway down this page and you will see a couple models with a digital readout on them:

carbon monoxide question?

hmmmm.....

i've never had anythink like this happen. the detector is a few years old, and all the sudden about 30 minutes ago i heard something beep and then i heard it beep again and realized it was the detector. when i went to see what was going on all it said was "Err." or what obviously means error. why is it doing this and whats going on?!?! never ever have i had the thing go off because of carbon monoxide! and its not showing numbers, i've tried unplugging it and it plugs in and lights up 888 [like it always does] and then goes to Err.

whats going on with it? am i safe, or should i get out of the house? and how do i fix this?

please i need help asap!

thanks!
@jala i'm so sorry about your in-laws!!! D:

and i would love to go get one, but its 2 am here and the closest walmart is like 25 mins away

Answer
Maybe you just need new batteries.
Your house is probably safe. If you're very concerned, sleep with a window open in your room until you can get batteries or a new detector.

Carbon Monoxide Compensation?

McUK

Well.. Long story short.. I got called from work from my letting agent to be told that there are high amount of Carbon monoxide coming out my house. So much that it set of the carbon monoxide alarm in the flat upstairs!
The reading on the meter reading came out at 99,999 ppm and a considered high is 50ppm. I was told if i was asleep i wouldve died!

Few days in a hotel which have been paid by the landlord, The engineer has said that there was a fault from the boiler and as the flue was covered in plants that it trapped the co2 and went through my en-suite extractor fan and entered the house!

My doctor has said i have had high levels of Co2 in my system and has been recorded on my medical record. Apart from the landlord paying for my hotels would i be entitled to any compensation or anything because of this? Considering i nearly died!

I look forward to your response.
CW - "My doctor has said i have had high levels of Co2 in my system and has been recorded on my medical record"

Answer
Were you permanently harmed or do you require any special treatment because of the elevated levels in your system? Is this a situation that will return to normal once the exposure is reduced?

In order to recover in a lawsuit you must have suffered a documented injury. Merely having elevated levels of one gas may not be considered an "injury." Also, you would have to show that your landlord was negligent, and that negligence was the cause of the elevated levels in your unit. You cannot recover for an injury you "nearly" suffered; only for those you actually suffered.

Also, carbon monoxide is CO. Carbon dioxide is CO2.

Rented Accomidation Carbon Monoxide Compensation?

McUK

Answer
Only your medical costs if those were not covered by insurance.
Sorry, but you need to actually die or be disabled in some way in order to cash in on this event.

You didn't nearly die. You could have become ill and I suppose died, but you didn't. Courts don't award damages for "what ifs", they only award damages for what you incurred as the result of someone elses negligence.

What is that beeping?

Jess

For the past few days, there would be a high pitched beep. Just one beep. Only once in a while. Now, theres a beep about every 30-40 seconds. It's getting on my nerves, but when I came to ask this question, I realized, could it be the Carbon Monoxide detector?

Answer
It most likely is the smoke alarm.

When these first came out, I must have spent 3 days looking for the dam cricket.

Carbon monoxide alarm going off?

Tic-Tac

During the day I always keep two windows open and usually the front door (I have house cats, they like to look/smell/head the outside). I'm a housewife, so I'm home pretty much 24/7 too.

Earlier this morning I was washing dishes when I kept hearing a beeping. The beeps were varied between 15 secs to 1min and sometimes came as just one or a group of about 3 beeps.
I looked for the source and found the (plug-in) kiddie carbon monoxide detector was the source of the noise. Since its a plug in, I know its not a battery issue, a small light saying to move to fresh air would flash on for maybe a second, then turn right back off.

Its never done this before and I'm a little bothered by it. Could it just have been a fluke? Maybe the alarm is old or something? (The alarm has been here since before we moved in)

It just seems weird that it would only flash on for a second. And the moment I moved the bookshelf (that's about 2ft from it) it just stopped altogether.
I was hand washing the dishes too...no appliances were on. We do have a gas oven/stove, but it hasn't been turned on since I made dinner last night.

Answer
If your detector has a battery, the battery may need to be changed. Our electric smoke detectors have backup batteries that need to be changed about every 18 months. It's also possible that the detector is old. You could also stop by your local fire station and ask the firefighters if they have any ideas. When we had a smoke detector that wouldn't stop beeping in the middle of the night (never during the day!), I asked our local firefighters and learned that smoke detectors only last for about 10 years. I don't know about carbon monoxide detectors.
