The highest level on the map is about 20,000ppb, or 20 ppm.
That would be less than in most any house in winter that was heated with an older indoor gas furnace/heater.
Today, OSHA sets a limit of 50ppm (50,000ppb) for workplace exposure.

Quoting: MarPep Not correct.
Concentration Symptoms35 ppm (0.0035%) Headache and dizziness within six to eight hours of constant exposure (OSHA Site Shutdown) I know this because one of our buildings got locked down. They put a red security tape on the gap of the doors, that showed if they had been opened. We had to wait till an inspection and remediation company came out. End result, facilities screwed the pooch and none of the air filters were changed for two years. Two of the six air handlers died. The second one spiked it and people were getting dizzy and bumping into things.
The cloud has been 3,200-3,00 ppb or 3.3-3.6 ppm for 4 days.
The damage is CUMULATIVE. And doesn't begin to repair itself until 7 days pass. CO kills the blood which kills your heart and lungs. Slow suffocation and death.
Quoting: Anonymous Coward 68506843 This Marpep knows jack squat.
Quoting: Anonymous Coward 68506843 MarPep is just quoting OSHA and EPA figures to you, and he has treated CO victims. CO poisoning is treated with 100 per cent O2, which greatly shortens the half life to hours. Bad cases need hyperbaric O2.
Quoting: MarPep I doubt it or you would have known these. Listen, we are not talking about a building. We are talking about everything out there around you and now the building is safe.
