The standard set out below contains only the requirements deemed necessary to provide protection before the conclusion of the rulemaking proceeding to be commenced shortly. Because exposure to VC is hazardous, and because such exposure esn occur in the processes of synthesising or polym erizing of VC or in the handling of VC polymers or copolymers which contain absorbed VC. this standard applies to all such processes end to the handling, re nting, manufacturing, proceseing. re the Code of Federal Regulations.

(1) This section applies to any area or operation In which vinyl chloride (ChloroeUiene), tives of the Assistant Secretary of Labor for Occupational Safety and Health and the Director of the National Insti tute for Occupational Safety and Health (NIOSK). (6) Employee access. Each employee and former employee shall have access to such records ef the results of monitoring required by this section as will Indicate his own exposure to airborne concentra tions of vinyl chloride. (7) Employee notf/icatiox. Each em ployer shall promptly notify smy em ployee who has been or is being exposed to vinyl chloride In concentrations In ex cess of 50 ppm, and shall inform him of the corrective action being taken. leasing, repackaging, or storage of any of these materials. The monitoring require ments serve two purposes, to trigger into operation a compliance program and to check tiro effectiveness of the program. Also, engineering controls are favored for compliance, and respirators are Intended to provide protection until such controls can be installed or In cases where such controls are not feasible. ' Accordingly, by reason of the foregoing and on the basis of the record of the hearing of February IS. 1974, with ex hibits, the written submissions received before the hearing pursuant to the notice of the hearing, the post-hearing written submissions by the participants at the hearing, the March 1974 report of a fact finding survey recommendations received from NIOSH, and the other data referred to herein, It Is found (1) that VC at con centrations in excess of SO ppm is physi cally harmful and carcinogenic; (2) that exposure to VC at concentrations in ex cess of a concentration of 50 ppm poses a grave dancer to employees; (3) that em ployees are presently exposed to VC at concentrations in excess of 50 ppm; and (4) that the emergency temporary stand ard set out below is necessary to provide immediate protection to employees from such danger. Pursuant to section 8(c) of the Occu pational Safety and Health Act of 1970, a proceeding will commence shortly la accordance with section 8(b) of the Act, in wntch the emergency temporary standard will serve as a proposed rule, together with other subsidiary rules. As soon as possible a draft environmental impact statement will be filed with the President's Council on Environmental Quality, and copies will be provided to other appropriate Federal agencies for their comments. Pursuant to sections 8(c) and 8(c) (3) of the Wllllams-Steiger Occupational Chemical Abstracts Service Registry Number 75015, Is manufactured, reacted, handled, processed, released, repacked, or stored. (3) This section does not apply to the handling, storage, or other, use of vinyl chloride polymers and copolymer* in the form of fabricated products. (b) Permissible exposure. The occupa tional environment shall be controlled so that no employee It exposed to vinyl chloride at a concentration In excess of 50 puts per million (ppm) (127.0 mg/cuip). (c) Monitoring--(1) initial monitor- fng. As soon as possible but not later than April 22. 1874, every employer of an em ployee working in an area or operation in which vinyl chloride is manufactured, re acted. handled, processed, released, re packed, or stored shall begin monitoring the ambient air of the area to determine whether It contains vinyl chloride In con centrations in excess of 50 ppm. (2) Frequency. Monitoring of a suffi cient number of employees so that a representative sample of exposures to vinyl chloride may be determined shah be accomplished not less frequently than weekly until all results for three oonsecutlvo weeks arc at or below 50 ppm. There after. monitoring shall be conducted not less frequently than monthly so long as the .concentrations of vinyl chlorida do not exceed 50 ppm. If a monitoring sam ple reveals vinyl chloride in concentra tions in excess of 50 ppm, weekly moni toring shall be resumed until all remits for three consecutive weeks art at or be low 50 ppm. (3) Method of monitoring. Personnel monitoring shall be accomplished by col lecting samples by suitable devices worn by the employee. The samples shall be analyzed by gas chromatography or by any other method which is of equivalent sensitivity. The analytical procedure shall be sensitive to 5 ppm of vinyl chlo . <d) Compliance. (1) Whenever any monitoring sample reveals vinyl chloride, at a concentration in excess at SO ppm,' or whenever any accident, such as rup ture of equipment or spillage, Indicates the likelihood of a greater than usual release of vinyl chloride Into the ambient air, all employees exposed to such con centrations shall be withdrawn to a aafe area and shall not be permitted to re enter the work area unless they wear either Type C continuous flow or pres sure demand air supplied respirators or self-contained breathing apparatus. . (3) Work which may reasonably be expected to release vinyl chloride in con centrations In excess of 50 ppm, such as repair, maintenance or cleaning of re actors or other equipment containing vinyl chloride, shall be accomplished only by employees wearing Type C continuous flow or pressure demand air supplied res pirators or self-contained breathing ap paratus. (3) In any ease covered by para graphs (d)(1) or (d)(2) of this section, in addition to providing the required respirators, the employer shall examine and analyze the source of the excessive concentrations of vinyl chloride in order to determine feasible engineering dr op erational controls appropriate to reduce the airborne concentrations to the permissable level. Such controls shall be Implemented as quickly os passible. (4) Periodic tests shall be conducted for equipment leaks and for emissions of vinyl chloride which may result from work practices. .3 In 29 CFR Part 1910', 11010.19 Is revised to read as follows; 11910.19 Special provision* for air con- .uminnnta, (a) Asbestos dust.
