' ` ` The adoption was made under Section 6(c) o f OSHA . following studies conducted by the National Institute for ' Occupational Safety and Health and recommendations made by the American Conference o f Governmental Indus trial Hygienists. NIOSH and ACGIH determined that existing standards constituted a grave danger to employees exposed to the eight-hour time weighted average concentra tion and that an emergency standard was necessary. NIOSH concurred that the change proposed by the ACGIH would provide a substantial base. Action under Section 6(b) o f the Act will begin soon. . Any notice o f proposed rulemaking under 6(b) will give notice of the emergency standard as a proposed rule o f any subsidiary proposals which may be required under subsec tions (5) and (7) of 6(b) relating to toxic substances. The emergency temporary standard had been called for in a letter to the Labor Department from the AFL-CIO. ; The letter cited evidence from a study conducted by Dr. Irvin J. Selikoff and the staff of the Mount Sinai School of Medicine, the AFL-CIO, and the Ad Hoc Committee on the Asbestos Hazard of the AFL-CIO Industrial Union Depart ment (Current Report, November 18, p. 581). The emergency standard appears in the Full Text section of this report and will be included in a future Reference File supplement. ..Asbestos _ ... OSHA PU8USH ES EM ERGENCY STANDARD ^ FOR ASBESTOS TO BE EFFEC T IV E IM M EDIATELY An emergency standard limiting the exposure of employ ees to asbestos dust was published by the Occupational Safety and Health Administration and made effective December 7. The emergency standard limits the eight-hour time weighted average airborne concentration of asbestos dust to which employees are exposed to no more than five fibers per milliliter greater than five microns in length. Concentra tions above five fibers per milliliter but, not to exceed 10 fibers per milliliter, may be permitted up to a total of 15 minutes in an hour for up to five hours in an eight-hour day. ^ Copyright 3) 197) by The Bureau of Notional Affairs, Inc. F u iB T e s i EMERGENCY STANDARD FOR EXPOSURE TO ASBESTOS DUST PU.B-L1SH_ED ?.Y THE OCCUPATIONAL SAFETY AND HEALTH ADMINISTRATION Chapter XVII-- Occupational Safety and Health Administration, De partment of Labor PART 1910-- OCCUPATIONAL SAFETY AND HEALTH STANDARDS Emergency S tandard for Exposure to Asbestos Dust Pursuant to section 6(c) of the Wil- ham s-Stetser Occupational Safety and i ! e_3li,h Act ^ 1970 <S4 Stat. 1596. 29 , P ir t t91 of Title 29.

The National Insti tute for Occupational Safety and Health concurs that the proposed change in the asbestos dust standard recommended by the American Conference of Govem m ental I n t e tr ia l Hygienists should be the substantial base for the emergency standard.
