Add a new paragraph (b) to read as follows and reletter all succeeding paragraphs accordingly:
**
*
(b) Permissible exposure to vinyl chloride
(b)(1)
For polyvinyl chloride production
facilities.
(i) Standard effective Oct. 5, 1974. The maximum concentration of vinyl chloride to which any employee may be exposed shall not exceed 40 ppm
nor shall the time-weighted average concentration exceed 25 ppm.
This will set forth the exposure limitations recommended by the various witnesses. It also re flects the recommendations of different standards for different manufacturing operations to set work place levels as low as feasible.
1/ The recommended changes are submitted as substituted language for that underlined in Column I unless it is indicated in Column I that language from Column XI is submitted to be added to the
proposed section as in the case of Section (a)(2).

It is the concensus of medical
opinion that there are no
diagnostic or screening
procedures that will detect
sensitivity or predisposition
to angiosarcoma of the liver.
Consequently a standard should
not specify v/hat tests should
be performed, but should leave
medical examinations to the
discretion
