"The Occupational Safety and Health Administration (OSHA) has established a maximum safe working level for carbon monoxide at 35 parts per million (ppm) over an 8 hour period, in the general work-place. The U.S. Environmental Protection Agency (EPA) has established that residential levels are not to exceed 9 ppm over an 8 hour average."

People don't spend 24-7 in a bar or other workplace like they might in a house. The OSHA limits are more applicable.

Why do the smoke nannies fear setting a real-number limit? The reason is clear: said limit could be acheived by engineering controls instead of behavior modification and the latter is their objective.

The crux - thank you!
