MEMORANDUM

TO: Mr. H. H. Fawcett
FROM: S. T. Quigley
^
SUBJ: OSHA Emergency Temporary Standard for Exposure to Vinyl Chloride
1 have enclosed a copy of the published emergency temporary standard for exposure to vinyl chloride previously described in my memoranda of March 29, 1974 (120-02LA-74) and April 1, 1974 (120-03LA-74). Since the
petitions for an emergency standard requested that the standard be based on the recommendations of the Standards Advisory Committee on Carcinogens, I have enclosed a copy of those recommendations as published in the Federal Register.
You will note that a rulemaking proceeding will soon be initiated' to develop a "permanent" standard. A proposed rule is expected to be published by April 19, 1974. It is based on the emergency standard and is more complete than the emergency standard in that it addresses the fire hazards of vinyl chloride as well as its toxicological properties.
Once the proposed "permanent" rule for exposure to vinyl chloride is
published, I shall forward a copy. A period of 60 days from the date of publication is generally provided for submission of comments to the Depart ment of Labor. Thus, assuming publication of the proposed rule by April 19, 1974 as expected, a tentative date of May 20, 1974 would be convenient for receiving the recommended comments of the Committee on Chemical Safety to allow coordination with any recommendations of the Committee on Environmental Improvement prior to transmitting a draft statement to the ACS Board of
Directors for approval.
If you have any questions regarding this matter, please contact this office.

1. Background. Vinyl chloride (chlo^o-
clhcnc), Chemical Abstracts Service Registry No. 76015, Is a synthetic chemi cal made by oxychlorlnntion of cthylettc
or by liydrochlormation of acetylene, it Is the parent compound of a scries of thermoplastic resnt polymers nnd co polymers which arc widely used for con tainers. wrapping tissues, electrical In
sulation. pipe, conduit and a variety of other products. Vinyl chloride has been made commercially In this country since 1939 and present production Is In excess of seven billion pounds per year.
Vinyl chloride (VC) Is a efts at am bient temperature ard pressure and Is ft chlorinntcd hydrocarbon which has mod
erate liver toxicity. The present standard sets a cclline value of 600 parts per million (ppm) (29 CFR 1910.93).
On Jahuary 22. 1974, the Occupational Safety and Health Administration was Informed by tire National Institute for. Occupational Safety ftd Health (NIOSII) that the B. F. Goodrich Chem-. leal jCompany reported that deaths of several of Us employees from a rare form of Uver cancer may have been occupa tionally related. As a result of (his notiflBallon, and after consultation with ^iOSH 'and a Joint inspection of the plant by OS11A, NIOSH, and the Ken tucky Department of Labor, a fact-find ing hearing on possible hazards involved with the manufacture and use of both VC and polyvinyl cldorlde was an nounced on jnnuary 30. 1971 (39 FR 3874), and-held on February 16. 1974.
The employees of the H, F. Goodrich
Chemical Company who died from an giosarcoma of the Uver had an average exposure of approximately ID years to vinyl chloride, nt -unknown concentra tions. nnd variable exposures to other volatile chemicals. (TR 93). Some em ployees Of Union Carbide Company and Goodyear Company arc also reported in a post-hearing comment from NIOSH dated March 11, 1974. to have had ex posure to vinyl chloride nnd to have died from angiosarcoma of the liver. Finally,
autopsies of four deceased employees re vealed that liver angiosarcoma tumors were histologically Indistinguishable
from the angiosarcoma tumors observed In Professor Mallonl's experimental anl-. tnals. It is concluded therefore, that
vinyl chloride Is carcinogenic lor hu mans,
We therefore conclude that the present
standard for VC should be lowered from a celling of 500 ppm to a ceiling of 50
ppm for the following reasons: (a) In light of the evidence referred
to above including the Maltoni experi ments demonstrating that VC Is carcino genic In animals at 250 ppm. we conclude that VC must be considered carcino genic In man at the same level:
(b) Although Professor Maltoni did
not Induce tumors In his experimental animals at nn exposure concentration of .50 ppm, these data do not support the concept that occupational exposure of employees to concentrations of 50 ppm throughout their working lifetime would bo without detrimental health effects;
ers International Union made a Joint petition for an emergency temporary standard for VC (TR 141-14B). which was also Joined by the Oil, Chemical and Atomic Workers International Union (TR 37). At the same hearing, several
participants urged, on the other hand, a regular rulemaking proceeding as the most suitable for the orderly develop ment of relevant Information (TR 112," 180'.
The petitions for an emergency tem porary standard specified In detail the contents of llie standnre. requested. In
substance, the request Is to Issue a com prehensive fully-developed standard based on the recommendations of the Standards Advisory Committee on Car cinogens submitted lo the Assistant Sec retary of Labor on or about August 27. 1973. The recommendations arc farranging. and cover special categories of
operations, signs and Labels, medical sur veillance. reporting, etc.. Including a per mit system for the use of a carrlnogi-n.
We agree that an emergency tempo rary standard Is necessary; we cannot say on the basis of the information developed
so far llmt a comprehensive standard, such as the one requested. Is either neces sary or even desirable. It has been de cided to promulgate a standard contain ing only those essential provisions which arc deemed necessary to provide protec tion to employees from grave danger until a regular rulemaking proceeding In accordance with sections 8 (b) an.: (c) of the Act can be concluded.
