Do you need a carbon monoxide detector if you don't have any gas running to your home?

carbon monoxide detectors malfunctioning image

Kay G

our house is 100% electric, so my thought is that you do not need a carbon monoxide detector because this poisionous gas comes from malfunctioning gas equipment. we live in Arizona and all the houses around us have no gas lines either, so do we need a co detector?

Answer
I would not purchase one if heat was electric.

what will carbon monoxide detector sound like if there is CO in home?

Chloegirl

I just plugged in a first alert carbon monoxide detector down in basement. The horn will sound once or twice every 20 minutes or so and the red light will flash every so often also. Is this a malfunction or is there CO in my home?

Answer
A very load chirping noise.

Is it possible to die from carbon monoxide poisoning in a old home?

Q. I heart from the local news a couple of years back that an old man in his 60s died from CO poisoning due to a faulty gas heater in his bedroom, and as he did not have any relatives, his body had been left to rot for one month before the authorities and coroner came to take him out. He also failed to install detectors.

Is it possible for old homes with faulty gas heaters to kill people like this? Should gas heating be banned then?

Answer
Y E S ! ! ! ! you can die from carbon monoxide poisioning. BUT there are kits you can buy. It's like a fire alarm. you put a battery & stick it on the wall. There is no need to ban gas heating.

CARBON MONOXIDE POISONING INJURY PLEASE HELP WITH THIS CASE. Need a jury simulation?

carbon monoxide detectors colorado image

PRMOLOMEE

20 year old gets Carbon Monoxide Poisoning from Incorrect instalation of furnace in town home rental?
Colorado 20 year old male suffers from carbon monoxide poisoning in a rented town home after a contractor worked on the furnace. Exposure to the carbon monoxide continued for 1 month resulting in hospitalization. The 20 year old man suffered a loss in color vision to his left eye, headaches 2-3 times week, memory loss, and incurred medical bills in the process. Please keep in mind that under colorado state law the property owner can not delegate there duties to maintain a safe environment for tenants to a contractor. They will still be held responsible for the actions of there employees (ie) contractor. Please decide if the owner should be held responsible for the injuries to the 20 year old? Should the contractor share that liability? how much compensation should the 20 year old get for his color vision, future medical care, loss of enjoyment, and loss of potential earning capacity?

Please put your idea of a fair settlement and what a likely verdict would be if you were on the jury?

Thanks
Additional Details
There was a carbon monoxide detector in place that the owner had by state law. When the contractor was working on the furnace he removed the co detector and when he replaced it he put the batteries in wrong.

Answer
I feel that both parties the landlord and contractor are liable. However, without knowing all the facts from both sides I cannot set a value amount. Usually only an attorney can do this.

Carbon monixide poisoning?...?

Sally2tits

I rent a small lock out basement in Colorado and recently found out my boiler had been releasing carbon monoxide, and fire, thankfully it turned itself off
. I have 2 year old daughter and my husband as well should we get checked out by a doctor? Should we take legal action against my landlord? State law is that a landlord has to provide a CO detector he only provided smoke detector. What do I do someone please help Im very confused and scared.

Answer
I would buy a small detector to keep in your home from now on, notify the landlord in writing of the incident, and request that they provide a CO detector. The landlord must respond within a certain amount of time according to your state and city laws.

They may ignore you or attempt to evict you on some other grounds so that's why you should buy a CO detector yourself. It's never a good idea to mix it up with a landlord unless you have money to move and are willing to do so. Write the letter immediately. You have a responsibility as a tenant to notify the landlord of such a situation even if you are afraid of retaliation. It shows a judge that you did the right thing.

No matter what the landlord does you have the right to sue in small claims court for the cost of any medical bills and damages you think you may be entitled to. If it is not well-documented and if the treating physician does not specifically state that you were suffering from CO most likely from the apartment, then your case will be dismissed for lack of evidence.

Additionally, you should seek out your local Landlord - Tenant Association for assistance and advice.

ALARM QUESTION!!!!!!!!!!!!!!!!!!!!!!!!!!!?

kidde carbon monoxide alarm questions image

Ashley

okay so right now they are doing the alarm test!!
and i have no idea what 3 bi bi bi means XP so help me please!!
okay last time at 11PM TO 3AM!! i didn't sleep a night!! they said it is a falls alarm when i tried to sleep the 3 bells starts!! and i got so mad!! i cried XD then it stop and it start!! and i have no idea what it means!!

Answer
We have a "FireX" Kidde Combination Smoke and Carbon Monoxide Alarm". This is a talking alarm and has 2 tests. I installed them in my apartment and my sister-in-laws. These are battery powered (3-AA) only. I installed them in 2003. Recently they began chirping every 30 seconds without any verbal remarks "Fire, Fire" or "warning "Carbon Monoxide" Finally I found the booklet and found on an interior page "After seven (7) years of cumulative power up, this unit will "chirp" every 30 seconds. This is an "operational end of life" feature which will indicate that it is time to replace the alarm.
There are battery powered, combination battery and electric or electric only powered alarms.
Our alarm is battery only and the Carbon Monoxide part is the 7 year life span part that does this.
The best thing that you can do is read through the instruction pamphlet. I had to look through it 3 times to find the small print.
You need to have it tested and a technician can do the best work. It sounds like you have an electric version and I don't think the "Smoke only" have a life span in years. Get it checked anyway just to be sure. I am sure a replacement is not expensive as in the US they are only $10 or so. I live in Spain now and can't get them here so I get them from the States every 7 years because I want both "Carbon Monoxide and Smoke Detectors even though we don't have gas. (They are about 30 dollars each Plus 30 for shipping.) Well worth it. "AA" batteries are available everywhere and don't need any other power. They should be changed every October. Mine lasted 2 years because the "Duracell" batterys I use are more expensive (from our local Camera store).
Good Luck ! ! !

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.

How do carbon monoxide detectors work?

carbon monoxide detector says 0 image

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:

What does it mean when my carbon monoxide alarm says the "Peak Level" is 26? Is this cause for concern?

newjediord

It never actually sounded, but the Peak Level went from 0, to 15, to 21, to 26. (There's a button you can push called Peak Level) So, does anyone know what this means? Do I have a slow-leaking source of carbon monoxide, or is my alarm just detecting other similar chemicals? As a side note, the alarm is in the kitchen, not in the ceiling, but on a counter.

Answer
The highest level it has detected is 26 parts per million, most will not alarm till 50 ppm. Get it out of the kitchen, simply cooking could cause the reading. I recommend you put detectors where you sleep.
Carbon monoxide is known as the silent killer because most become victims while they are
are sleeping. Candles, burnt food, gas stoves, auto exhaust, gas water heaters and gas furnaces are examples of things to look for. Exposure to over 5ppm is not recommended for any length of time. It is also possible your detector is faulty, I would not bet on that. Take the time to sort this one out.

short story twisting ending?

carbon monoxide detectors on sale image

Braden J

I have to write a short story about a character that we had to make up with 8 character traits i chose Brave Independent Mischievous Daring Dreamer Calm Bold Determined, but i can not think of a ending. here is what i have so far. note this is a rough draft i havent gone through spelling and grammar. Thanks!

It was a hot summers day, the sun was beating heavily down upon the scorched bleachers, fresh air overwhelmed by hot dogs, beer, and carbon monoxide, it was the year of 1975, Sunday, a father and son day for my dad and I, a day I will never forget. The crowd anticipated the big Daytona 500 race to being, the roaring engines make it understandable why today the big race day is the most exciting times of the year. The art of racing was new to me but I was hooked âWhen I'm grown up, I wanna be a racecar driver. I wanna get into one of them cars an' go really fast.â I have repeat those words for years, wished upon every star. If it my wishes didnât come true I would make it come true.

15 years later, Iâm stuck at a dead end job, a sales person at a local dealership barely making ends meet, dreading each and everyday, my dreams are dead. Itâs a typical morning, the dew fresh on the ground, the sun rising over the horizon, people are walking zombies until they get their daily caffeine fix. I was in my 1999 Nissan Skyline Gtr R34, my last hope of going fast in this world equipped with a high performance 500hp engine and a shot of NOZ it was truly all that and a bag of chips. It was a straight stretch, quarter mile away from my work I creped up to a red light, a young kid in a Nissan 370z pulled up next to me revving his engine, he doesnât know what he is up against as I chuckled quietly to myself, I revved my engine back it purred like a kitten with my new H pipe exhaust, to signal the race was on.

I sat back in my seat waiting for the light to change, it felt like two life times, the light triggered green, beep, beep ,beep, my radar detector went crazy, a cop right near me. It was to late, I took off like a rocket, the cop quickly caught on, we were racing. The cop flicked on his siren and the chase was on My heart beating out of my chest, I guess I wonât be going to work this morning. I slammed the gas pedal to the floor, I was going so fast I couldnât see the other cars just blurs passing by, clearly I won the race but there was a bigger picture in my mind, the police. No matter what I knew I couldn't stop running. I had no idea where I was running to, or where I would end up I just had to lose the police.

âWe have a 10-44 in progress, these guys are good requesting back upâ, blared over the radio, I was in over my head in trouble all because of a dream to go fast. Everything was in slow motion I glanced into my rear view mirror, it was filled with red and blue lights, there had to be at least 20 police cars behind us, I looked over to my right, my opponent had a face filled with Concentration and desperation. We were weaving in and out of the morning rush traffic avoiding accidents by inches. My tires squealed as a pulled up on my e brake to make a sharp turn, the radio blared once again âthe racers are breaking up stay on your vehicle repeat stay on your vehicleâ

Answer
It depends on how short you want your story to be. If you want it to be shorter, you can have the main protagonist crash and wake up in the hospital, with the last thought or line being something like " No matter how hard you try, you can't run away from your life".
Or, if you want your story to be longer you could have the main protagonist get away from the cops and dream about that one time that he went against the flow and did something daring (i.e. the race).

does anybody knows what is 'msa gas'?

Jimlberto

http://www.multigasdetection.com/?gclid=CK6NrardpJYCFQECGgodpEta5g

in this link, I was reading the last paragraph and collided with this :
"Some of the Gases Detected by some of the above detectors include
Ammonia gas , Carbon Dioxide , Carbon Monoxide , Chlorine Dioxide , Chlorine , Combustible gas detection, Fluoride , Fluorine Hydrogen , Hydrogen Chloride , Hydrogen Cyanide , Methane , Nitrogen Dioxide , Oxygen detetector, Phosphine , Sulfur Dioxide , carbon monoxide, helium, hydrocarbon, hydrogen gas , methane , msa gas ,monoxide, propane , radon gas. "

there it says. ", msa gas,"

I've searched 'msa gas' and only found a company that makes masks and detectors, but nothing about a "msa gas"

does it ring any bell to somebody?
oops, i put 'knows', It should have been 'know', sorry
ah, ok, I supposed that, somehow, but 'surely' , I was not sure, he he

thanks for your time folks

Answer
It is likely that this vendor doesn't have a chemist on staff reviewing what the sales department puts on the website -- it becomes really obvious when I see things like "fluorine hydrogen", and carbon monoxide three times.

In all likelihood, the folks in the RKI sales office are using the term "msa gas" to describe Mine Safety Appliances' Calibration gas for multi-gas detectors.

Why did my carbon monoxide detector go off?

carbon monoxide detector goes off image

Shell c

My digital carbon monoxide detector went off and it read GAS. So, I called the gas company and they sent out an emergency technician. He checked my stove, oven, furnace, outside meter. Everything! He checked for gas leaks and carbon monoxide but nothing showed up. He said everything was fine. So, why did my alarm go off? I bought a new one and it hasn't went off.

Answer
Sometimes it's just due to a weak battery or even dust that builds up on the detector. Most of the time its a false alarm but alway better to be safe then sorry. I have went on many 911 calls for a co detector going off and it's usually a false alarm due to a weak battery or malfunction. Batteries should be changed at least every 6 months and the detectors cleaned. This is for both co detectors and smoke detectors. Hope this helped.

Why does my carbon monoxide alarm keep going off?

LoveuEndle

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.

I accidentely warmed my engine with the garage door shut should I be worried?

carbon monoxide detectors at home depot image

Prezence

I really didnt mean to I just went to start my car and then I left it running while I- was in the garage with the door shut for about a minute and a half. Im really worried about my health, the house and the health of my family. I only felt dizzy for about 5 minutes and Im feeling better now. All the windows and doors in the house are open and the garage door is opened now. Should I still be worried?

Answer
1. Buy a carbon monoxide detector. The ones with the nice numerical readouts cost $35. You can find them at Home Depot.
2. You've ventilated your home so everything is currently fine.
3. If your family wasn't in the garage with you, they're fine.
4. I would really not worry about this. People react very differently to low levels of toxic exposure, but we're exposed to so much car exhaust & other environmental toxins in our lives that I can't imagine 90 sec of car exhaust would make the needle budge.

Now I'll go out on a limb. If this was an attempt to harm yourself, then please get help--even though you decided against it today. Talk to a family member or friend, call a suicide hotline, or call your doctor.

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

carbon monoxide detector reading 50 image

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 ft² of living space.. assuming you have 8ft ceilings.. and assuming the temp is about 25°C, so that density of air = 1.2 g / dm³.. you have this much air at any point in time.

(1000 ft² x 8ft) x (12 in / ft)³ x (2.54cm / 1in)³ x (1 dm / 10cm)³ x (1.2g / dm³) 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 is a safe level of carbon monoxide?

carbon monoxide detector 400 ppm image

kalashniko

i bought a new digital carbon monoxide detector...it has readings up to 400( not sure what the units of measurement are) it records a week's worth of c0 levels...i had it for a couple of days and decided to check it and it said the highest reading of c0 so far was 131....but it didnt go off....so im assuming that that is still a safe/inhabitable area.....the question is....what is a dangerous level of c0 and who do i call to service my gasboiler/ gas heater cause those are the only things in my house that are powered by gas....do i call my gas guy? or my heating/cooling guy? thanks in advance

Answer
Carbon monoxide is measured in parts per million (ppm). Any CO levels higher than 10-20 should be alarming. Especially inside of a residence. If it recorded a CO level of 131 and didn't alarm, then you might want to look into getting a new detector. If you were home at the time the level was 131, you would be dead within a few hours. The signs/symptoms of acute (new onset) CO poisoning start out as headache, reddening of face, dizziness, and progress to nausea, vomiting, trouble walking and soon thereafter, unconsciousness and death. So yes, get a hold of a professional about your furnace, washer/dryer, or whatever your think the CO source may be. Hope this helps.

AP Chemistry homework help!!?

Faith

OK, so I did several problems, but there are slight differences when comparing my answers to the book answers. Can someone please find the mistakes.

1. A baby was born who weighs 3.91 kg and measures 51.4 cm. Convert the weight to pounds and ounces and her length to inches.

My answer: 8.62 lbs, 138 oz, and 20.2 in.
Book answer: 8lbs, 9.9oz, and 20.5 in.

2. The world record for the hundred meter dash is 9.74s. At this speed, how long would it take to run 1.00 x 10^2 yards?

My answer: 8.91 sec
I don't have the book answer for this problem, but an online answer states that it is 8.85 sec (100/11.3) where did the 11.3 come from?

Carbon Monoxide (CO) detectors sound an alarm when peak levels of carbon monoxide reach 100 parts per million(ppm). This level roughly corresponds to a composition of air that contains 400,000 micro grams carbon monoxide per cubic meter of air. Assuming the dimensions of a room at 18ft x 12ft x 8ft, estimate the mass of carbon monoxide in the room that would register 100ppm on a carbon monoxide detector.

My answer : 1.98 x 10^7 ug
Is my answer correct? If so, does that mean I complete ignore the 100 ppm when doing calculations?

Thank you!

Answer
1
As far as question 1 is concerned, I think you misunderstood what they were asking. The question wants you to take the weight in kg and convert it to a COMBINATION of pounds and ounces. In other words, they want the pounds as a whole number - and the fractional portion (.62) in ounces.
You converted kg to lb correctly 3.91 kg = 8.62 lbs ... or 8 lbs and (.62) x 16oz/lb = 9.92 oz. Instead, you gave the answer as a decimal and then converted that number (8.62) to ounces (138 oz).
Converting cm to in ... 1 cm = .3937 in
51.4 cm x .3937 in/cm = 20.2 in

#2
The question is asking: If a runner runs 100m in 9.74s, how fast can he/she run 100 yds ?
First convert 100 yards to meters ...
100 yds x .9144 m/yd = 91.44 m
So ... if a runner can run 100m in 9.74s, how long will it take the same runner to run 91.44m (100 yds) ?
Set up a ratio and solve for x.
100m /9.74s = 91.44m/x s
100x = 890.62
x = 8.906 = 8.91s
Looks like I agree with you, lol !!
Even if you look at it another way ...
100m in 9.74s = 10.266 m/s
91.44m x 1 sec/10.266m = 8.907s
(I think we're right and your online source is wrong, lol).

#3

First I calculated the area of the room (in ft^3) then I converted that to m^3 (cubic meters)
(18)(12)(8) = 1728 ft^3
1 m^3 = 35.314 ft^3
1728 ft^3 x 1 m^3/35.314 ft^3 = 48.93 m^3
The alarm sounds when the air composition reaches 400,000 micrograms/m^3 = .0004g/m^3
Multiply the area of the room in cubic meters by the alarm rate in g/m^3
48.93 m^3 x .0004 g/m^3 = .019572 g/m^3 = 19,572 micrograms

See how that matches up with other answers - good luck !!

After cooking on our new gas stove last night for approximately 30-45 minutes, my husband said that the carbon monoxide detector in our bedroom read a level of 15ppm. This is the highest we have seen it, generally speaking it doesn't go over 10ppm. At what point (in ppm) should we be concerned?

Answer
Any level of carbon monoxide is dangerous, it inhibits hemoglobin, myoglobin, and mitochondrial cytochrome oxidase (which are all VERY important!).

But typically, a concentration of as little as 0.04% (400 parts per million) carbon monoxide in the air can be fatal.

Below is a chart to help elaborate on the toxicity levels of CO and its symptoms:
* 35 ppm (0.0035%) Headache and dizziness within six to eight hours of constant exposure
* 100 ppm (0.01%) Slight headache in two to three hours
* 200 ppm (0.02%) Slight headache within two to three hours
* 400 ppm (0.04%) Frontal headache within one to two hours
* 800 ppm (0.08%) Dizziness, nausea, and convulsions within 45 minutes. Insensible within two hours.
* 1,600 ppm (0.16%) Headache, dizziness, and nausea within 20 minutes. Death in less than two hours.
* 3,200 ppm (0.32%) Headache, dizziness and nausea in five to ten minutes. Death within 30 minutes.
* 6,400 ppm (0.64%) Headache and dizziness in one to two minutes. Death in less than 20 minutes.
* 12,800 ppm (1.28%) Unconsciousness after 2-3 breaths. Death in less than three minutes.

In addition, a recent report concludes that carbon monoxide exposure can lead to significant loss of lifespan after exposure due to damage to the heart muscle.

Should i be worried my carbon manoxide detector is reading 23?

Felisha

I have an electric carbon monoxide detector that is reading 23... I do not have my furnace on, we do not have a garage attatched but we do have natural gas. Is this something we should worry about.

Answer
Yes, you should be worried, but not in a panic. You either have a defective alarm, or you have CO leaking into your home. By UL standards the alarm should not alarm for 30 days when the amount is 30 ppm or less. Call your gas supplier and see if they will come out and check it for free.

Time to change my Carbon Monoxide Detector?

carbon monoxide detectors life expectancy image

Guy Robert

I've had the same CO detector in my home for many years now, perhaps more than 7 years. The lights work (both POWER and CAUTION) and every time I press the TEST button it lets out the loud beep that it should when CO is in the air. My concern, however, is whether or not the detector is still as functional as it was when it was purchased.
Granted, I've been using the same smoke detector for 20 years and it seems to work A-OK, but are CO detectors any different?

Answer
There is a certain life expectancy in smoke and CO detectors. I read in a technical bulletin they last about 7 years. Reason is, sensitivity parameters change through the years. Put your mind at ease and install new units, also change batteries when we set our clocks ahead and back. (Easy to remember)

My CO alarm went off. will it go off again after resetting it?

stax

i aired the house out an d reset the alarm. it has not gone off again. will it go off again i8f the CO level gets too high?

Answer
CO detectors usually have a five year life expectancy. Over time they can become less accurate and affected by temperature and humidity swings. Even low levels of carbon monoxide can be dangerous for your family so don't take the alarm lightly. Take the time to find out why the alarm went off and have the issue resolved. Detectors usually trigger above 70 parts per million after 15 minutes. Once the concentration of CO goes down, the alarm will reset and monitor the air for future conditions.

can a gas furnace (Gaffers & Sattler brand) be producing carbon monoxide?

carbon monoxide detectors high or low image

bradzepfan

I live in a house with an old Gaffers & Sattler brand gas furnace/heater. Could this thing be releasing carbon monoxide? My house carbon monoxide detectors have never set off the alarm but perhaps the release from the furnace could be below its threshold. I would appreciate any advice on what situations might exist with the furnace that could produce carbon monoxide and what the solutions might be.

Answer
The older the furnace the higher the CO danger. I don't think they make yours anymore, may be 20+ years old. You know how the blower does not come on at first, allowing the heat to accumulate in the furnace "heat exchanger" before blowing it out. Over the years the heat exchanger expands and contracts, there is oxidation that occurs and the walls get weak and pop a crack. This is a primary cause of of CO output in furnaces that are properly ventilated. Have a Contractor come out and check the CO at the flue and in the home airstream.

Good research will show that the highest selling CO Detectors don't do an adequate job and everyone needs a "low level" monitor.

Is there a valid test available to the public for low-level carbon monoxide posioning?

Doro

A recent magazine claims up to 8 million Americans suffer from MUSES Syndrome (mulitsensory sensitivity). The toxic overload that mimics the flu... low-level carbon posioning.

I have all the symtoms they list: headaches, fatique, dizziness & hypersensitivity to light, sound, smell & touch. Not so much taste. Staying focused is also a problem. My line of work depends on being alert - focused. I had to drop back to part time status in order to be able to continue in accounting. I really need to work full time financially but can't handle it right now.

We have used a coal stove for the last 20 yrs. & have had some carbon exposure when there is a down draft. We keep a window cracked for that reason. The carbon detector has been as high as 224.

How can I tell if my symptoms are truly related to carbon? I have only a slight improvement during the months the stove is not in use.

Any help is greatly appreciated.

Answer
There is a test called an Arterial Blood Gas, using a CoHgb module on the co-oximeter. There is a direct measurement for carbon monoxide in the blood. Using high-flow/ high oxygen concentrations is the fastest most potent way to remove the carbon monoxide from the blood.

Why does my carbon monoxide alarm keep going off?

carbon monoxide detectors keep going off image

LoveuEndle

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.

Why does my Carbon Monoxide detector keep going off?

Stephen T

We have a brand new First Alert smoke/carbon monoxide detector. One day it was going off when I came home for lunch. I called the fire dept. and they came and did a test and said my levels were normal for the basement. A few weeks ago it started going off again so I opened a window. We felt no symptoms. This morning it went off yet again.

Is my device faulty? What could be the problems. Every time it has gone off I have replaced the batteries just in case the signal meant low battery.

Answer
I would try a different unit (or even different brand) and see if the results are the same. You might even try getting separate smoke/CO detectors and try different locations. And if it goes off again, I would have the fire department come and check more than the basement (and they should use two detectors to make sure THEIR readings are accurate). There's a whole myriad of factors involved here; I wouldn't rest until I was sure I wasn't in any danger. People die from CO poisoning every day. I've found a couple of websites that might help:

My carbon monoxide detector is going off every 30 seconds? ?

carbon monoxide detector 30 seconds image

Bri<3

My carbon monoxide detector is going off like every 30 seconds or so. i changed the battery and its still going off. it just goes off in my room and we have detectors all over the house.
is it dangerous?
what should me and my pets do?:D
PLEASE HELP!! THANKS!

Answer
you should certainly be concerned.

you said you have other CO detectors in the house, move a different one to the location where the alarming one is. seek "confirmation".

do both detectors alarm now?

if so, seek professional help immediately, open all of your windows, turn on any fans.
strongly consider leaving the house if you are at all unsure.

my carbon monoxide detector is beeping once every 15 to 30 seconds. anybody know why it is doing that? It is n?

Jaspal

It is not battery operated. Seems to be the one in the basement.

There's a ninja in your basement.

on a nighthawk detector what numbers are considered unsafe?

carbon monoxide detector 888 code image

Nay

We have a Nighthawk carbon monoxide detector in our home. The number 8 just recently appeared on the screen. Should we be concerned? No alarm has gone off.

Answer
I just installed one of those the other day and I would have sworn that 8 was an error code that I got and that you just have to unplug the detector and plug it back in. But I just looked at the manual online and there is no mention of 8 being an error code. It does display "888" for a few seconds when you fist plug it in.

If it is steadily displaying an 8 then that is the level of carbon monoxide that it has detected since last reset. On the one hand that is a very low level and is safe - some references put the maximum continuous exposure level at 35 ppm and some say 50 ppm. Either way, 8 ppm is very low.

But then you have to wonder where the 8 ppm came from and if it is from a leak than may get worse over time. Having a CO detector is a good thing, it will make plenty of noise if the levels ever get to the point that you need to take action.

You could call Kidde at 800-880-6788 and talk to them if you want some reassurance.
