Occupational exposure to chloroprene : criteria for a recommended standard

"Criteria and recommended standard for preventing occupational disease arising from exposure to chloroprene (126998) are presented. The proposed standard applies only to the occupational exposure to chloroprene, as defined by the Occupational Safety and Health Act of 1970. Available evidence indicates that the primary hazards in the manufacture of chloroprene arise from inhalation of the vapor and skin contact with the liquid; the compound may cause central nervous system disorders, liver disorders, cardiovascular system disorders, and kidney disorders. According to the proposed standard, the employer shall control exposure to chloroprene so that no employee is ever exposed at a concentration greater that 1ppm, or 3.6 milligrams per cubic meter of air, determined as a ceiling concentration for any 15 minute sampling period during a 40 hour workweek. Criteria for sampling, analysis, medical examinations, labeling and posting, respiratory protection, work practices, sanitation practices, monitoring and recordkeeping, are outlined.
