carbon monoxide detector 400 ppm image
Q.
Answer
Concentration 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; loss of judgment
400 ppm (0.04%) Frontal headache within one to two hours
800 ppm (0.08%) Dizziness, nausea, and convulsions within 45 min; insensible within 2 hours
1,600 ppm (0.16%) Headache, tachycardia, dizziness, and nausea within 20 min; death in less than 2 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. Convulsions, respiratory arrest, and death in less than 20 minutes.
12,800 ppm (1.28%) Unconsciousness after 2-3 breaths. Death in less than three minutes.
How much your gas heater produces would have to be measured.
If you are running a gas heater or any appliance that uses fossil fuel, you should have a co detector.

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.
