The National Institute for Occupational Safety and Health (NIOSH) has shown that carbon monoxide (CO) exposure levels which can induce carboxyhemoglobin (COHb) formation in excess of 5 percent can result in serious health consequences.

In Dade County, Florida county vehicle inspectors are routinely exposed to CO on the job. To evaluate CO exposure levels, a Ecolyzer direct reading CO meter was placed in inspection lanes in 10 Dade County vehicle inspection stations.

The results of this study indicate that in 3 stations, an 8-hour time-weighted exposure to carbon monoxide will induce inspector COHb levels in excess of 5 percent, and all stations have work sites where inspectors encounter ceiling exposure levels which may alter their predicted level of COHb formation.

Although CO exposure in Dade County vehicle inspection stations was found to be influenced by several factors, the extent and severity of exposure can be reduced by engineering and administrative controls.
