Description:Environmental sampling for lead (7439921), fluorides, total chromium (7440473), manganese (7439965), and nickel (7440020) and urinary samples for fluoride (16984488) were done on January 22 and 23, 1979 at Eastern Associated Coal Corporation (SIC-5084), Federal No. 2. Sampling was in response to a request by company officials to evaluate the exposure of surface weld shop workers to hazardous materials. Except for lead, all substance levels were below evaluation criteria; and all urinary concentrations were within normal limits. Two of 11 lead samples (0.09 and 0.11 milligrams of substance per cubic meter or air) exceeded and 2 other samples were equivalent to the OSHA standard for lead of 0.05 milligrams of substance per cubic meter of air. It is concluded that proper protective measures should be taken when welding and cutting previously painted metal surfaces and work procedures for use of the degreasing tank should be improved. It is recommended that a substitute be found for the use of lead base paint and that a preoperation be done to remove the lead base paint from the welding area. Local exhaust ventilation should be provided in the welding shop. Ventilation also should be provided when welding in a confined area, along with a NIOSH/Mining Safety Health Administration approved airline respirator for fumes. Gloves that are resistant to methyl-chloroform (71556) should be worn when using the degreasing tank, and the tank should be covered with a tight fitting lid when it is not in use.
