Industrial Hygiene Walk-Through Survey Report of Colorado Chemical Specialties, Golden, Colorado

摘要

A walk through survey was conducted at Colorado Chemical Specialties (SIC-2821), Golden, Colorado in August, 1985. The purpose of the survey was to evaluate exposure to 1,3-butadiene (106990) during the manufacture of homopolymer and copolymer liquid polybutadiene resins. Bulk samples of styrene (100425)/butadiene and polybutadiene resins were analyzed for residual 1,3-butadiene. The resin was produced by solution polymerization. Engineering controls consisted of equipping all pumps handling 1,3-butadiene with single or dual mechanical seals. The quality control laboratory was equipped with exhaust hoods. Quality control sampling was performed using vapor phase gas chromatography. Personal monitoring for 1,3-butadiene was limited to a single survey conducted by OSHA in the mid 1970s. No detectable concentrations of 1,3-butadiene were reported. No 1,3-butadiene was detected in bulk samples of styrene/butadiene and polybutadiene resins. Employees received periodical physical examinations; however, pre-employment physicals were not required. Employees received on the job safety training only. There was no established formalized respirator program. The company did not have an organized industrial hygiene program. The authors conclude that the facility is not suitable for an in depth study.
