Walk-Through Survey Report of Frog, Switch, and Manufacturing Company, Carlisle, Pennsylvania.
NIOSH 1980 Feb:3 pages
Worker exposures to manganese (7439965) (Mn) were determined at the Frog, Switch, and Manufacturing Company (SIC-3325) in Carlisle, Pennsylvania, on May 22, 1979. The company was under consideration for inclusion in a NIOSH study of the health effects of occupational Mn exposure. Approximately 308 of the employees at the facility were assigned to production or maintenance jobs. The company had a safety and industrial hygiene program. Medical services were provided by a local hospital and clinic. All air samples for Mn were below the OSHA standard of 5.0 milligrams per cubic meter (mg/cu/m). Three samples approached or exceeded the standard of 1.0mg/cu/m Mn fume adopted by the The American Conference of Governmental Industrial Hygienists. Iron-oxide (1332372) fume concentrations in the large arc-air gauging booth, and in the torch cutting booth exceeded the OSHA standard of 10mg/cu/m. The authors conclude that this facility should not be included in the Mn hazard study because of the use of respiratory protective equipment among workers and the general low concentrations of airborne Mn observed throughout the facility.
