NIOSH Control Technology Assessment of the Plastics and Resins Industry: Methods and Approach.
NIOSH 1981 Jan:21-24
The objectives and design of the NIOSH control technology assessment of the plastics and resins industry were described. The emphasis was on seven addition polymerization processes used to manufacture thermoplastic resins, elastomers, and synthetic rubber, since they make up a large percentage of the industry output. The engineering control technology used to reduce worker exposure was assessed by factory surveys of all operations in nine polymerization processes. Polyvinyl-chloride (9002862) factories were subject to high priority because of strict regulations and sophisticated control technology. Also of high interest were processes using styrene (100425), in particular styrene/butadiene (106990) rubber facilities. Polyolefin addition and solution polymerization processes and compounding operations were not included in the survey. The two problems encountered were gaining voluntary access to well controlled plants selected for survey and budgetary restraint. Although extensive monitoring data were already available in most polyvinyl-chloride facilities, this was not the case for other sites, and limited sampling was done for assessment. Details of sophisticated controls were considered proprietary and were described only in relation to performance criteria.
