events and attractions theater venues and eventsAt what level do carbon monoxide detectors alarm?
Levels of carbon monoxide exposure range from low to dangerous: Low level: 50 PPM and less. Mid level: Between 51 PPM and 100 PPM. High level: Greater than 101 PPM if no one is experiencing symptoms.
Also question is, will carbon monoxide detectors detect low levels?
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. Some detectors are more sensitive and will, when exposed for many hours, detect or alarm at lower levels.
Furthermore, what should you do if your carbon monoxide detector is detected?
