O2 Sensors read 20.9% of the environment. That means everything is MINIMIZED by about 5 times. Take a look at the IDLH of the common toxics as related to O2 alarms. A monitor set up for LEL-O2-CO-H2S will NOT alarm for a IDLH presence of Chlorine, Ammonia or Hydrogen Cyanide. Small changes in O2 percentage are BIG CHANGES in safety levels.
