Safety Standards for General Industry and Construction

AGENCY: Occupational Safety and Health Administration, Department of Labor.

ACTION: Final rule; technical amendments.

SUMMARY: The Occupational Safety and Health Administration (OSHA) is making nomenclature changes, address changes, and minor technical amendments to OSHA standards for construction and general industry. These changes reflect transfers of authority and editorial corrections to construction and general industry standards that have not undergone recent revision. For example, this document reflects the replacement of the Atomic Energy Commission by the Nuclear Regulatory Commission and the transfer of certain regulatory authority from the Internal Revenue Service to the Bureau of Alcohol, Tobacco and Firearms.

This document also corrects typographic errors in tables of decompression times for employees who work in compressed air environments. In addition, typographic errors in tables of rated capacities for different sizes, configurations, and types of wire rope and synthetic web slings are being corrected.

EFFECTIVE DATE: June 30, 1993.

FOR FURTHER INFORMATION CONTACT: Mr. James F. Foster, U.S. Department of Labor, Occupational Safety and Health Administration, room N-3647, 200 Constitution Avenue, NW., Washington, DC 20210; telephone: (202)219-8151.

SUPPLEMENTARY INFORMATION:

Background

Section 6(a) of the Occupational Safety and Health Act of 1970 (29 U.S.C. 655) authorized the Secretary of Labor to adopt national consensus standards and established Federal standards issued under other statutes, including the Contract Work Hours and Safety Standards Act (the Construction Safety Act) (40 U.S.C. 333), as occupational safety and health standards, On May 29, 1971 (36 FR 10466), OSHA promulgated 29 CFR part 1910 Occupational Safety and Health Standards, to incorporate certain national consensus standards and established Federal standards for general industry. Subsequently, on December 30, 1971 (36 FR 25232), the Agency redesignated the existing standards in 29 CFR for ship repairing (part 1501), shipbuilding (part 1502), and shipbreaking (part 1503), and construction (part 1518) as 29 CFR parts 1915, 1916, 1917, and 1926, respectively. Parts 1910 and 1926 still contain various cross-references to the earlier versions of these standards which need to be updated to reflect their redesignations.

In addition, there have been changes regarding the Federal agencies and the consensus standard organizations whose standards were adopted by OSHA under section 6(a). In particular, there have been changes in the names of certain agencies and in the addresses of certain organizations. OSHA's existing standards do not fully reflect the above-noted developments. In addition, several standards either adopted under section 6(a) or promulgated under section 6(b) contain typographic errors. Therefore, the Agency has determined that this technical amendment is necessary to update and correct OSHA's safety and health standards as set forth below.

In particular, 29 CFR 1910.5(c)(1), which addresses the applicability of general industry standards, twice refer to a specific standard for ship repairing, once as 29 CFR 1501.23(c)(3) and then as 29 CFR 1915.23(c)(3). The second reference correctly reflects the 1971 redesignation of the ship repairing standards, while the first reference does not. However, neither reference correctly reflects the 1982 consolidation of the shipyard employment standards (47 FR 16985, April 20, 1982), under which the standard in question was redesignated as 29 CFR 1915.34(c)(3). OSHA is amending 1910.5(c)(1) so that the provision correctly reflects the redesignation of the pertinent standard.

Also, this technical amendment clears up some other loose ends left over from the 1971 redesignation and from the subsequent consolidation of 29 CFR parts 1915, 1916, and 1917 into 29 CFR parts 1915, Shipyard Employment, published on April 20, 1982 (47 FR 16985). Existing 1910.13 through 1910.15 reference either 29 CFR parts 1501, 1502, or 1503. In order to reconcile the General Industry standards to the above-noted redesignations and consolidations. OSHA is merging the provisions of existing 1910.13, 1910.14, and 1910.15 into a single 1910.15, "shipyard employment," and amending 1910.15 so it refers to 29 CFR part 1915.

In addition, several standards being revised so that they reflect the current addresses of the National Fire Protection Association, the Compressed Gas Association, and the American Petroleum Institute, as set out in lists of standards organizations referenced in the regulatory text. The sections being amended to reflect the current address of these organizations include 1910.40, 1919.100, 1910.109, 1910.116, 1910.171, 1910.190, and 1910.275, and appendixes B through D to subpart L.

OSHA's initial set of standards for general industry and construction, promulgated in 1971, included standards for ionizing radiation which referred to the Atomic Energy Commission (AEC). However, those reference's have been obsolete since 1974, when the Nuclear Regulatory Commission. (NRC) assumed the role previously held by the AEC. This document amends the general industry and construction standards to reflect the above-noted transfer of authority. The pertinent sections are 1910.96 (general industry) and 1926.53 (construction).

In the general industry health and environmental control standard for ventilation, 1910.94, paragraph (a)(5)(i) addresses the selection of personal protective equipment. That provision states that only approved equipment shall be used to protect personnel against dusts produced during abrasive-blasting operations and names the U.S. Department of the Interior, Bureau of Mines as the authority to approve respirators for such use. Additional references to respirator approval by the Bureau of Mines appear in paragraphs (c)(6)(vii)(a) and (d)(9)(vi) of that same section. Also, 29 CFR 1910.134(b)(11), which addresses the selection of respiratory protection, requires that approved or accepted respirators be used when they are available. That provision cites the U.S. Department of Agriculture and the U.S. Department of the Interior, Bureau of Mines, as authorities competent to set standards for respirators. Existing paragraph (b)(11) further states that, while pesticide respirators listed by the U.S. Department of Agriculture continue to be accepted for specified pesticides, the U.S. Department of the Interior, Bureau of Mines, is the agency now, responsible for testing and approving pesticide respirators.

Pursuant to the Federal Mine Safety and Health Act of 1977 (30 U.S.C. 957), the respirator approval function once delegated to the Bureau of Mines (and for part of the 1970's, to the Mining Enforcement and Safety Administration) has been delegated to the Mine Safety and. Health Administration (MSHA) and the National Institute for occupational Safety and Health (NIOSH). The procedures and requirements to be met in obtaining NIOSH/MSHA approval for respirators are set out in 30 CFR part 11. Therefore, OSHA is amending 1910.94(a)(5)(ii)(c)(6)(vii)(a), and (d)(9)(vi) and 1910.134(b)(11) to reflect the current requirements for the approval of respirators. Also, in the health standard for occupational exposure to vinyl chloride (29 CFR 1910.1017(g)(2)), there is a reference to the Mining Enforcement and Safety Administration (MESA), Department of the Interior. This outdated reference is being changed to reflect the transfer of authority for the approval of respirators from MESA to MSHA.

This document also corrects errors in OSHA's standard for slings used in general industry material handling (29 CFR 1910.184). These errors first appeared when the code volume containing 29 CFR part 1910 volume was reprinted in 1977 and 1981. The errors are numbers contained in tables that express rated capacities for particular types of wire rope and synthetic web slings (N-184-7, N-184-20, N-184-21, and N-184-22).

On June 27, 1975 (40 FR 27367), OSHA published a standard covering slings used in general industry material handling operations. In that standard1910.184), requirements for the use of alloy steel chain slings, wire rope slings, metal mesh slings, fiber rope and synthetic web slings were set out. The standard includes tables that indicate the maximum safe capacities for different sizes and configurations of the various types of slings covered by the standard.

The tables to 1910.184 were printed correctly in part 1910 of the 1976 edition of the CFR volume. However, when the CFR volume was reprinted in 1977, typographic errors appeared in Table, N- 184-7 and Table N-184-20. In addition, when the part 1910 volume was printed in 1981, other errors appeared in Tables N-184-20, N- 184-21, and N-184-22 This document amends the sling capacities listed in those tables to correct those errors.

In existing general industry standards that address toxic and hazardous substances (subpart Z), there are references to the Department of Health, Education, and Welfare (HEW). These appear in a section of the safety standards for diving (1910.401(a)(2)(iii)) and in paragraph (b)(6) that is repeated in a number of OSHA health standards (1910.1003 though 1910.1018, 1910.1044 and 1910.1045). These outdated references are being changed to reflect the redesignation from HEW to the Department of Health and Human Services (HHS). Under the Department of Education Organization Act (Oct 17, 1979, 20 U.S.C. 3411 and 3508). HEW was redesignated as HHS. effective May 4, 1980. (Functions pertaining to education were transferred to a newly created Department of Education.) In addition, in the construction standards, OSHA is amending 1926.451(y)(9) so that it refers to 1926.1053, instead of to 1926.450. On November 14, 1990 (55 FR 47687), the Agency deleted 1926.450, "Ladders," replacing that section with new 1926.1053, "Ladders." This change provides the correct reference for employers who have employees use ladders while performing construction work on pump jack scaffolds.

Also, OSHA is amending 1926.451(y)(11), which addresses the provision of guardrails on pump jack scaffolds, to correct a typographic error, so that it refers to 1926.451(a)(5) instead of 1926.451(a)(15). This change provides the correct reference for employers who comply with 1926.451(y)(11) by providing standard guardrails.

Elsewhere in the construction standards, under subpart S "Underground Construction, Caissons, Cofferdams, and Compressed Air," 1926.800 addresses certain underground operations for tunnels, shafts, chambers, and passageways. In paragraph (q)(8) of that section, which applies to drilling and jumbo decks, an error arose in the process of codifying the standard. The change corrects an inadvertent paragraph designation of (i) that falls between paragraph (iii) and precedes (v). The amendment redesignates that paragraph as (q)(8)(iv).

In another section of that same subpart, the standards cover employees who are exposed to compressed air working environments. Procedures for gradual decompression of employees working in these environments are set out in 1926.803(f)(1), which in turn references decompression tables in appendix A to the subpart. The tables list conditions, according, to working chamber pressure and exposure time, and give specified uniform rates and timed incremental stages for pressure-reduction for an employee's return to normal condition.

In Decompression Table No. 2, for a working chamber pressure of 22 pounds per square inch gauge (p.s.i.g.), the number "133" is being inserted in the last column under the heading "Total time decompress minutes" for Stage number 2 for a working period of over 8 hours. In addition, in the same table, for a working chamber pressure of 50 p,s.i.g. and a working period of 5 hours, the entries in the fourth through eighth (last) columns are being shifted over one column to the left. (This amended version corrects the entries to read that they are for Stage 1 and a pressure reduc. p.s.i.g. from 50 to 34, with a time in stage of 3 minutes, and a pressure reduc. rate of 0.20 min/pound). Under the same working chamber pressure of 50 p.s.i.g. for a working period of 5 hours, at Stage 3, the entry "1.42" for pressure reduc. rate min/pound in the next to last column is being changed to "11.42."

In the construction standards that cover blasting and the use of explosives (in subpart U of part 1926), there are several outdated references to regulations promulgated by other Federal agencies. The references to Internal Revenue Service (IRS) rules in the standard for storage of explosives and blasting agents (1926.904) and the definitions applicable to the subpart (1926.914) are being changed to reflect the redesignation and transfer of certain rules to the Bureau of Alcohol, Tobacco and Firearms. In addition, the standard for surface transportation of explosives (1926.902) is being amended to reflect the removal, redesignation, or transfer of Department of Transportation rules in titles 14 and 49 of the CFR.
