Survey Report of Metalizing Operation, Rock Island Arsenal, Rock Island, Illinois.
NIOSH 1978 Mar:11 pages
An industrial hygiene survey to determine the type and extent of exposures that exist from thermal spraying operations during metalizing at the Rock Island Arsenal, Rock Island, Illinois, is reported. The facility is under the command jurisdiction of HQ ARRCOM. Products manufactured at the plant are mainly artillery or tank components (SIC-3489) such as gun mounts, equilibrators, gun carriages, loaders and rammers, small arms, grenade launchers, and aircraft weapon subsystems. A total of 13 general area and personal air samples were collected during the investigation. Samples were analyzed for trace metal fumes. Aluminum (7429905), iron (743986), zinc (7440666), and cadmium (7440439) did not exceed current standards. Copper (7440508) fumes, however, exceeded standards in one of nine samples. Zinc-oxide (1314132) samples were below the standard of 5.0mg/m3. Detected levels of ozone (10028156) were below the current standard of 0.1ppm. Noise levels measured during spraying operations range from 119 to 121dBA, well above the 90dBA standard set by OSHA. It is recommended that the ventilation system in and around the spraying area be updated and that all workers in the metalizing area be kept on the hearing concentration program.
