Title Occupational Safety and Health Standards - Standard for exposure to vinyl chloride.
Bibliographic information 4 Oct. 1974, Vol.39, No.194, p.35890-35898.
Abstract This amendment to the Williams-Steiger Occupational Safety and Health Act of 1970 is dated 1 Oct. 1974 and came into force on 1 Jan. 1975. It adds a new section 1910.93q applying to any area or operation where vinyl chloride monomer (VCM) is manufactured, reacted, handled, processed, released, repacked or stored. A standard of permissible exposure to VCM is laid down (TLV: 1ppm averaged over any 8h period; ceiling of 5ppm averaged over any period not exceeding 15min; no employee to be exposed to direct contact with liquid VCM). The standard gives background information on VCM and its carcinogenicity (animal experiments, exposure limits, etc.) and contains provisions for the monitoring of employees (initial monitoring, frequency, method of monitoring, training, keeping of employee records, access of employees to records, etc.), and employee protection ("action level" of 0.5ppm averaged over an 8h work day; regulated areas; respiratory protection; training; emergency stations). An abridged French version of this standard has been published (Traduction INRS 29 A-75) by Institut national de recherche et de sÚcuritÚ, 30 rue Olivier-Noyer, 75014 Paris Cedex 14, France.
