Applies to occupational exposure to DBCP (CAS 96-12-8) except exposure solely from its application and use as a pesticide; storage, transport, distribution and sale in sealed intact containers are subject only to the emergency, training and hazard communication paragraphs. The PEL is 1 ppb as an 8-hour TWA, and eye and skin contact is prohibited. There is no action level and no STEL. Regulated areas must be established wherever concentrations exceed the PEL, with access limited to authorized persons, and eating, drinking, smoking and cosmetics are prohibited there. Monitoring must be representative of each employee's 8-hour exposure, measured without regard to respirators, and accurate to plus or minus 25 percent at 95 percent confidence at or above the PEL. After initial monitoring of each workplace and operation, repeat at least every 6 months where exposures are at or below the PEL and at least quarterly where above it, returning to 6-monthly only after two consecutive results at least 7 days apart are at or below the PEL; monitor again after production, process, control or personnel changes. Employees are notified within 15 working days, with corrective action described where the PEL is exceeded. Engineering and work practice controls are required to the extent feasible, supplemented by respirators. A written compliance program with a detailed schedule must be revised at least annually and be available to OSHA, NIOSH and employees. Respirators under a 1910.134 program are used during control installation, infeasible maintenance, insufficient-control operations and emergencies; atmosphere-supplying respirators are specified, and for entry into or escape from unknown concentrations a full-facepiece pressure-demand supplied-air respirator with auxiliary SCBA or a pressure-demand SCBA. A written emergency plan is required for each workplace where DBCP is present, with a general alarm, evacuation, and post-emergency monitoring. Impermeable protective clothing and eye protection must be provided wherever eye or skin contact is possible, clean at least daily, removed only in change rooms, stored in closed labeled containers, and never cleaned by blowing or shaking. Surfaces must be free of visible DBCP, dry sweeping and compressed air are prohibited, dedicated labeled vacuums are used, and waste goes in sealed containers. Change rooms, end-of-shift showers in regulated areas, filtered positive-pressure lunchrooms and handwashing before eating are required. Medical surveillance at no cost is provided to employees working in regulated areas at initial assignment and annually, including reproductive history, genito-urinary examination with sperm count, and serum FSH, LH and total estrogen (females); employees exposed in an emergency receive a sperm count (or hormone tests) as soon as practicable and again three months later; an employee who develops signs or symptoms associated with DBCP exposure gets an additional examination. The physician receives the standard and exposure information and gives a written opinion. Training covers Appendix A, operations, respirators and surveillance. HCS compliance is required, including cancer, reproductive, liver, kidney, CNS, irritation and acute toxicity hazards, and DANGER signs mark regulated areas. Exposure and medical records are kept at least 40 years or duration of employment plus 20 years, whichever is longer. Employees may observe monitoring. Appendices A to C are informational.
