(3) This section applies to the trans portation of vinyl chloride or poly vinyl chloride except to the extent that the Department of Transporta tion may regulate the hazards covered by this section.
<b) Definitions. (1) "Action level" means a concentration of vinyl chlo ride of 0.5 ppm averaged over an 8hour work day.

to observe monitoring snd measuring procedures.
(4) "Director" means the Director,
National Institute for Occupational Safety and Health. VJ8. Department of Health, Education, and Welfare, or
his designee. (5) "Emergency" means any occur
rence such as, but not limited to. equipment failure, or operation of a
relief device which is likely to, or does, result in massive release of vinyl chlo ride.
(6) "Fabricated product" means a product made wholly or partly from
polyvinyl chloride, and which does not require further processing at tempera tures, and for times, sufficient to cause mass melting of the polyvinyl chloride resulting in the release of vinyl chloride.
(7) "Hazardous operation" means
any operation, procedure, or activity where a release of either vinyl chlo ride liquid or gas might be expected as a consequence of the operation or be cause of an accident in the operation,
which would result in an employee ex posure In excess of the permissible ex posure limit.
(8) "OSHA Area Director" means

(8) "Polyvinyl chloride" means poly vinyl chloride homopolymer or copo lymer before such is converted to a fabricated product.
(10) "Vinyl chloride" means vinyl chloride monomer.
(c) Permissible exposure limit. (1) No employee may be exposed to vinyl
chloride at concentrations greater
than 1 ppm averaged over any 8-hour period, and
(2) No employee may be exposed to
vinyl chloride at concentrations great er than 5 ppm averaged over any
period not exceeding IS minutes.
(3) No employee may be exposed to vinyl chloride by direct contact with liquid vinyl chloride.
(d) Monitoring. (1)A program of ini tial monitoring and measurement
shall be undertaken in each establish ment to determine if there is any em
ployee exposed, without regard to the
use of respirators, in excess of the
action level.
(2) Where a determination conduct ed under paragraph (dMl) of this sec tion shows any employee exposures, without regard to the use of respira tors, in excess of the action level, a
program for determining exposures for each such employee shall be estab lished. Such a program:
(i) Shall be repeated at least month ly where any employee is exposed, without regard to the use of respira tors, in excess of the permissible expo
sure limit. (ii) Shall be repeated not less than
quarterly where any employee is ex posed. without regard to the use of respirators, in excess of the action level.
(iii) May be discontinued for any em ployee only when at least two consecu tive monitoring determinations, made not less than S working days apart, show exposures for that employee at or below the action level.
(3) Whenever there has been a pro duction, process or control change which may result in an increase in the release of vinyl chloride, or the em ployer has any other reason to suspect that any employee may be exposed in
excess of the action level, a determina tion of employee exposure under para
graph (d)(1) of this section shall be performed.
(4) The method of monitoring and measurement shall have an accuracy (with a confidence level of 05 percent) of not less than plus or minus 50 per cent from 0.25 through 0.5 ppm, plus or minus 35 percent from over 0.5 ppm

exposures to vinyl chloride shall be controlled to at or below the permissi ble exposure limit provided In para graph (c) of this section by engineer ing, work practice, and personal pro tective controls as follows:
(1) Feasible engineering and work practice controls shall immediately be used to reduce exposures to at or
below the permissible exposure limit.
(2) Wherever feasible engineering and work practice controls which can be instituted immediately are not suf ficient to reduce exposures to at or
below the permissible exposure limit, they shall nonetheless be used to reduce exposures to the lowest practi cable level, and shall be supplemented by respiratory protection in accord ance with paragraph (g) of this sec tion. A program shall be established and implemented to reduce exposures to at or below the permissible expo sure limit, or to the greatest extent feasible, solely by means of engineer ing and work practice controls, as soon as feasible.
(3) Written plans for such a program shall be developed and furnished upon
request for examination and copying to authorized representatives of the Assistant Secretary and the Director. Such plans shall be updated at least every six months.

Until April 1. 1976. each employee who chooses not to wear an appropriate respirator shall be informed at least
quarterly of the hazards of vinyl chlo ride and the purpose, proper use. and limitations of respiratory devices.
(2) Respirators shall be selected from among those jointly approved by the Mining Enforcement and Safety Administration. Department of the In terior, and the National Institute for Occupational Safety and Health under the provisions of 30 CFR Part 11.
(3) A respiratory protection program meeting the requirements of $ 1910.134 shall be established and maintained.
