They are NOT required to warn of low-levels of CO.

The UL standard requires detectors to alarm within 90 minutes when exposed to 100 ppm; 35 minutes when exposed to 200 ppm and 15 minutes when exposed to 400 ppm..

What are normal carbon monoxide levels in a house?

Average levels in homes without gas stoves vary from 0.5 to 5 parts per million (ppm). Levels near properly adjusted gas stoves are often 5 to 15 ppm and those near poorly adjusted stoves may be 30 ppm or higher.

Can you recover from carbon monoxide?

Mild carbon monoxide poisoning causes headache, nausea, dizziness, difficulty concentrating, vomiting, drowsiness, and poor coordination. Most people who develop mild carbon monoxide poisoning recover quickly when moved into fresh air.

Depending on the degree and length of exposure, carbon monoxide poisoning can cause: Permanent brain damage. Damage to your heart, possibly leading to life-threatening cardiac complications.

Should a carbon monoxide detector read zero?

The continuous digital display indicates the level of carbon monoxide (if any) the unit is sensing. … Note: If the unit does not sense any CO, the display reading is zero (0). In most homes, the unit reads “0” all the time. A reading of “0” is expected under normal conditions, and is good.

How can I check my home for carbon monoxide?

What does ppm mean on a carbon monoxide detector?

parts per millionCO concentration is measured in parts per million (ppm). Most people will not experience any symptoms from prolonged exposure to CO levels of approximately 1 to 70 ppm but some heart patients might experience an increase in chest pain.

What is a safe level of carbon monoxide?

The OSHA PEL for CO is 50 parts per million (ppm). OSHA standards prohibit worker exposure to more than 50 parts of CO gas per million parts of air averaged during an 8-hour time period. The 8-hour PEL for CO in maritime operations is also 50 ppm.

What happens if you don’t get treated for carbon monoxide poisoning?

If you breathe in large amounts on CO, your body will begin to replace the oxygen in your blood with CO. When this occurs, you can become unconscious. Death may occur in these cases. You should go to the hospital right away if you’ve been exposed to a source of CO, even if you don’t show symptoms of CO poisoning.
