Background (events and toxicological findings) of the standard; scope and application; definitions of terms; requirements for regulated areas; routine operations; reactor and vessel entry; maintenance and decontamination; hygiene measures; signs; information and training; environmental monitoring and record keeping; reports; medical surveillance. Despite the fact that animal experiments have shown no liver tumors at atmospheric concentrations of 50 ppm, the concept of an allowable working level is rejected, since there is probably no threshold for carcinogenesis. Any person exposed to measurable concentrations of vinyl chloride should wear an air-supplied respirator, since chemical cartridge respirators do not afford adequate protection against vinyl chloride vapors.
