Abstract
Worker exposure to ethylene-dibromide (106934) (EDB) and general hygienic conditions were investigated at the Nalco Chemical Company (SIC-5051) in Freeport, Texas, on June 28, 29, and 30, 1977. A total of 15 personal air samples were collected at the blender operator, shift superintendent, and laboratory technician stations during an entire work shift. The company provided a full time medical technician, preemployment and annual physical examinations, and a monitoring system for hazardous substances. Protective equipment was required in the production area. All EDB sample concentrations were below the current OSHA 20 parts per million threshold limit for an 8 hour time weighted average value. The authors conclude that existing controls are adequate to maintain current Federal standards. A potential exposure was present in the EDB and blend handling systems. They recommend additional investigation of emission sources and upgraded sealing systems.
