Evaluation of potential exposure to carbon monoxide and metals.
Int J Occup Environ Health 2009 Apr; 15(2):229-230
The HHE Program responded to a request at a state vehicle maintenance garage. The request concerned potential exposure to carbon monoxide (CO) and metals such as arsenic, cadmium, and lead that may have accumulated on work surfaces throughout the garage. HHE Program investigators measured CO when vehicles were running in the garage and collected surface wipe samples for metals on work and nonwork surfaces. The investigators found that CO concentrations were well below occupational exposure limits. Arsenic was not detected in any of the surface wipe samples. Low concentrations of cadmium and relatively high surface lead concentrations were detected on the bench grinder and chain saw sharpener workbenches. Lead was either not detected or detected in trace concentrations on other work and nonwork surfaces. HHE Program investigators recommended that vehicles not be permitted to idle in the garage and that both garage doors be kept open and exhaust fans used when vehicles are running. Investigators recommended that managers ensure that the bench grinder and chain saw sharpener workbench surfaces are cleaned each day after use. Investigators recommended that employees remove personal protective equipment before using the break or kitchen areas and store it in a clean area when not in use. Employees should wash hands before eating, drinking, or smoking to prevent ingestion of lead and other metals.
