BHB>^ 10166 RULES AND REGULATIONS Title 29--LABOR Chapter XVII--Occupational Safety and Health Administration, Depart ment of Labor PART 1910--OCCUPATIONAL SAFETY AND HEALTH STANDARDS National Consensus Standards and Established Federal Standards Pursuant to authority in sections 6(a) and 8<g) of the Williams-Steiger Occu pational Safety and Health Act of 1970 (84 Stat. 1593, 1600; 29 U.S.C. 655, 657), Chapter XVII of Title 29 of the Code of Federal Regulations, established on April 13, 1971 (36 F.R. 7006), is hereby amended by adding thereto a new Part 1910 to read as set forth below. The provisions of 5 U.S.C. 553 concern ing notice of proposed .rulemaking, pub lic participation therein, and delay in effective date are inapplicable by virtue of the exception to 5 U.S.C. Ch. 5, pro vided in section 6(a) of the Act. The new Part 1910 contains occupa tional safety and health standards which are either national consensus standards or established Federal standards. The national consensus standards are occupational safety and health standards adopted and promulgated either by the American National Standards Institute (ANSI) or by the National Fire Protec tion Association (NFPA) under proce dures whereby it can be determined that persons interested and affected by the scope or provisions of the standards have reached substantial agreement on their adoption. I have determined that those standards have been adopted and pro mulgated under such procedures. Ac cordingly, pursuant to this determina tion, after consultation with other appropriate Federal agencies, and in ac cordance with section 3(9) of the Act, I do hereby designate as national consen sus standards those standards in Part 1910 which are standards adopted and promulgated by either the American Na tional Standards Institute or the Na tional Fire Protection Association. The national consensus standards contain only mandatory provisions of the stand ards promulgated by those two organiza tions. The standards of ANSI and NFPA may also contain advisory provisions and recommendations the adoption of which by employers is encouraged, but they are not adopted in Part 1910. The established Federal standards are operative occupational safety and health standards in effect on April 28, 1971, and established by the Department of Labor pursuant to section 107 of the Contract Work Hours and Safety standards Act, as amended (40 U.S.C. 333); section 41 of the Longshoremen's and Harbor Workers' Compensation Act, as amended (33 U.S.C. 941); the Walsh-Healey Pub lic Contracts Act, as amended (41 U.S.C. 35); the Service Contract Act of 1965 (41 U.S.C. 351); or pursuant to the National Foundation on the Arts and Humanities Act (20 U.S.C. 951). In any proceeding to enforce any such standard, brought corresponding standard under any of such statutes or under the 1910.12 of new Part 19!*Tu i1 Williams-Steiger Occupational Safety come effective on the ; ** and Health Act of 1970, the principle of respect to such employtocoi wve**, collateral estoppel will be followed. of employment.

Authority: The provisions of this Part 1910 Issued under secs. 6(a). 8(g), 84 Stat. 1593, 1598: 29 U.S.C. 655, 657. Subpart A--General 1910.1 Purpose and scope, (a) Section 6(a) of the WilliamsSteiger Occupational Safety and Health Act of 1970 (84 Stat. 1593) provides that "without regard to chapter 5 of title 5, United States Code, or to the other sub sections of this section, the Secretary shall, as soon as practicable during the period beginning with the effective date of this Act and ending 2 years after such date, by rule promulgate as an occupa tional safety or health standard any na tional consensus standard, and any es tablished Federal standard, unless he determines that the promulgation of such a standard would not result in im proved safety or health for specifically designated employees.'' The legislative purpose of this provision is to establish, as rapidly as possible and without regard to the rule-making provisions of the Ad ministrative Procedure Act, standards with which industries are generally fa miliar, and on whose adoption interested and affected persons have already had an opportunity to express their views. Such standards arc either (1) national con census standards on whoso adoption af fected persons have reached substantial agreement, or (2) Federal standards al ready established by Federal statutes or regulations. (b) This part carries out the directive to the Secretary of Labor under section 6(a) of the Act. It contains occupational safety and health standards which have been found to be national consensus standards or established Federal stand ards. 1910.2 Definitions. As used in this part, unless the con text clearly requires otherwise: (a) "Act" means the Williams-Steiger Occupational Safety and Health Act of 1970 (84 Stat. 1590).
