Abstract
The health hazards from lead (7439921) or tin (7440315) compounds during welding and soldering operations were determined at Molitor Industries, Incorporated (SIC-3490), Englewood, Colorado in June and October, 1982. Air samples were collected on 37 millimeter atomic adsorption 0.8 micron pore density cellulose membrane filters. Air was drawn at 1.5 liters per minute with a vacuum pump. Work practices, personal protective equipment, and techniques used to exhaust and dilute contaminants were also assessed. Lead content ranged from 0.01 milligrams per cubic meter (mg/m3), exceeding the NIOSH and OSHA standard of 0.05mg/m3. Tin samples ranged from nondetectable to 0.39mg/m3, exceeding the OSHA 0.1mg/m3 standard. Elevated lead and tin exposures were found during confined space operations. Health hazards were found when employees performed welding and soldering operations during a portion of the work period, especially when tin was the primary component. There were no work related health complaints reported. The investigators conclude that employees are overexposed to lead and tin during various phases of the welding and soldering operations. Personal protective equipment should be utilized, smoking prohibited, and monitoring should be conducted.
