National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Environmental/Industrial Hygiene Surveys of Vinyl Chloride Monomer Manufacturing Operations and Operations Where Polyvinyl Chloride and Copolymers of Polyvinyl Chloride Are Processed.

PB82109976

Publication Date	1975
Personal Author	Barnhart, W. L.; Toney, C. R.; Devlin, J. B.
Page Count	118
Abstract	Worker exposures to vinyl-chloride (75014) (VC) were surveyed at three VC manufacturing and seven polyvinyl-chloride (PVC) processing facilities (SIC-2821). Breathing zone and area air samples were taken in various areas within each facility, and were analyzed by flame ionization gas chromatography. VC concentrations in the three manufacturing companies ranged from 0.01 to 5.89, 0.01 to 84.77, and 0.02 to 21.8 parts per million (ppm), respectively. Personal exposures in excess of the 1.0ppm standard occurred for the laboratory technicians, operators and loaders at two manufacturing facilities, and for the loaders, operators, chromatography operators, and shift supervisors at the third facility. No detectable VC concentrations were found at six of the aeven PVC facilities. At the seventh facility, VC concentrations ranged from 0.02 to 2.44ppm. The blender operators, driverbaggers, and banbury operators were exposed to excessive VC concentrations. The authors conclude that excessive VC exposure exists at several of the facilities surveyed. They recommend use of respirators and protective clothing, installation of devices to detect excessive VC concentrations in the work areas and use of positive air pressure in laboratories and eating and smoking rooms.
