Description
Summary:The employee exposures to hexamethylene diisocyanate (HDI) during spray-painting operations were investigated. Personal breathing zone (PBZ) and general area air samples were collected for HDI, volatile organic compounds (VOC), particulate matter, and silica. All sampling pumps were calibrated before and after each sampling period. HDI airborne concentrations were measured using two impingers containing 15 mL of 0.03% 1-(9-anthracenylmethyl) piperazine in butyl benzoate. Air velocity measurements were made within each side-draft style paint booth in a grid fashion at approximately 3-foot intervals across the length of each outlet and every 18 inches above the floor. It was found that the spray booth in the East paint shop had inadequate air velocity at all four exhaust outlets.
