Just some facts from Monona's news letter on CO exposure.
OSHA has a permissible exposure limit for an eight hour work day of 50 ppm.
Even OSHA thinks this is too high but industrial lobbies have blocked
lowering it.
Worse - OSHA's PELs are designed to protect only "almost all" healthy adult
workers.
EPA standards for air quality - as you can see - the EPA thinks the OSHA
limit of 50 ppm is considered hazardous.
EPA AIR QUALITY INDEX for CO
8 hour (ppm)
Good - 4
Moderate - 9
Unhealthy for sensitive groups - 12
Unhealthy - 15
Very unhealthy - 30
Hazardous - 40 - 50
So the CO detectors you can buy at a local hardware store are probably
going to save you life when they go off but not your health - so put em
where you can see the ppm's displayed.
Check out the low level CO detectors at www.aeromedix.com
for a few dollars more ..........
