In response to a request from the owners and operators of Rocky Mountain Radiator, Boulder, Colorado, an evaluation was made of possible hazardous lead (7439921) exposures occurring while employees repaired automobile radiators. After disassembling and cleaning the used radiators, they were reassembled using soldering wire composed of lead and tin. Analysis of breathing zone air samples indicated lead exposures which exceeded OSHA standard (0.05 milligrams per cubic meter) in four of the six samples taken. Lead levels in the blood of three workers showed that the two radiator repair persons had levels slightly in excess of the upper limits of normal, and higher than the other employee. One radiator repairman demonstrated a free erythrocyte protoporphyrin (FEP) concentration which was significantly elevated. The authors conclude that a potential health hazard existed from overexposure to lead at this facility. The authors recommend that smoking, eating, and drinking be prohibited in the work area; that workers exercise good personal hygiene; that local ventilation be installed over the booths where the radiators are melted down; that workers be given clean clothes at the start of each shift; that dirty clothes remain at the facility for cleaning; and that workers have blood lead levels checked annually.
