An industrial hygiene survey of the North Ordnance Division of FMC Corporation, Minneapolis, Minnesota, to determine potential health hazards resulting from both torch brazing and thermal spraying processes is reported. The facility is involved in naval ordnance and artillery maintenance (SIC-9999). Eight personal and general area air samples were collected to determine the type and extent of metal fume and gas exposures. Samples were analyzed for the trace metal content of nickel (7440020), manganese (7439965), chromium (7440473), zinc (7440666), silver (7440224), beryllium (7440417), copper (7440508), and lead (7439921). In 5 of 24 analyses concentrations of copper at .01 to .011mg/m3, manganese at than the limit of detection. Zinc-oxide (1314132) concentrations were within current standards. Ozone (10028156) and nitrogen- dioxide (10102440) were also below limits of detection. However, a potential for peak exposures to increased concentrations does exist during periods of increased heavy work loads. An updated ventilation system in the wire form metalizing area is recommended.
