carbon monoxide alarm 30 ppm image
John
Its beeping once every 30 sec. I dont have batteries to change them now. Should i be worried?
Answer
Never ignore a CO alarm. This alerts before an emergency, before symptoms giving you time to resolve the problem.
You should be testing and vacuuming the cover monthly.
Have you looked at the display?
LB for low battery.
Don't ignore a reading of 30 PPM.
You can reset or call the toll free consumer hot line to diagnosis over the phone and assist you with any questions.
You can open windows, vent appliances, back car out of garage a safe distance from the living quarters.
An emergency would be a reading of 100 ppm without symptoms.
50-100 should be a concern but not ignored.
Elderly, pregnant women, small children who are more susceptible should be watched for symptoms such as headache, fatigue, dizziness and nausea.
If you do a test and reset and it reactivates within 24 hours, call a qualified technician.
So, to sum up:
* Get out of the house and call 911 if the carbon monoxide alarm starts beeping loudly.
* Change the battery if alarm chirps one quick little beep every few minutes.
* If you need more advice, call the nonemergency phone number for your fire department.

can carbon monoxide detectors detect small amounts?
mEl
i have an older furnace and i have a detector but i was wondering if the detectors detect small trace amounts of cm or only the major leaks.
Answer
Basically there are 3 levels that should activate the alarm 70 ppm, 150 ppm and 400 ppm depending upon how long the levels are detected.
I am a home inspector. I check CO as part of my inspection. Most furnaces and water heaters operating in normal conditions will have less than 20 parts per million in the flue stack (after the vent diverter). So 70 ppm CO is a pretty high level.
Kitchen ranges often exceed 400 parts per million on startup.
Ceramic log sets usually peg the meter at 2000 ppm.
From 1st Alert one of the leading manufacturers of home alarms:
<< WHAT LEVELS OF CO CAUSE AN ALARM?
Underwriters Laboratories Inc. Standard UL2034 requires residential CO
Alarms to sound when exposed to levels of CO and exposure times as
described below. They are measured in parts per million (ppm) of CO over
time (in minutes).
UL2034 Required Alarm Points*:
⢠If the alarm is exposed to 400 ppm of CO, IT MUST ALARM BETWEEN
4 and 15 MINUTES.
⢠If the alarm is exposed to 150 ppm of CO, IT MUST ALARM BETWEEN
10 and 50 MINUTES.
⢠If the alarm is exposed to 70 ppm of CO, IT MUST ALARM BETWEEN
60 and 240 MINUTES.
* Approximately 10% COHb exposure of 10% to 95% Relative
Humidity (RH).
The unit is designed not to alarm when exposed to a constant level
of 30 ppm for 30 days.
CO Alarms are designed to alarm before there is an immediate life threat.
Since you cannot see or smell CO, never assume itâs not present.
⢠An exposure to 100 ppm of CO for 20 minutes may not affect average,
healthy adults, but after 4 hours the same level may cause headaches.
⢠An exposure to 400 ppm of CO may cause headaches in average, healthy
adults after 35 minutes, but can cause death after 2 hours. >>
