Carbon Monoxide Danger Levels

Exhaust Removal Products – Technical Documents – Carbon Monoxide Danger Levels

For a safe working environment, automotive tailpipes should be no further than a few feet from open air. The exhaust must dispersed in open air to keep carbon monoxide (CO) levels below 200 parts per million. If the tailpipe exhaust cannot rise directly from the tailpipe to open air a hose and tailpipe adapter should be used to funnel the fumes to the open air and away from human contact. In these unassisted setups the hose should not extend beyond eleven feet and the hose should be kept as straight as possible. There is not enough line pressure to move the exhaust much beyond eleven feet. When the tailpipe exhaust must travel farther than eleven feet it is strongly recommended and generally required by O.S.H.A. that power-assisted room ventilators or a ducted, blower assisted system be installed.

See our Exhaust Removal catalog and Blower Selection Guide for more information on Blower Selection and Exhaust Removal Products for necessary information and equipment for these systems.
