Section 6(a) of the Williams-Steiger 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 subsections 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
occupational safety or health standard any national consensus standard, and any established Federal standard, unless he determines that the
promulgation of such a standard would not result in improved 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 Administrative Procedure Act, standards with
which industries are generally familiar, and on whose adoption interested and affected persons have already had an opportunity to express their views.
Such standards are either (1) national concensus standards on whose adoption affected persons have reached substantial agreement, or (2) Federal
standards already established by Federal statutes or regulations.
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 standards.
