OSHA published a final rule for the Design Safety Standards for Electrical Systems (Electrical Standard) on February 14, 2007, after determining that electrical hazards pose a significant risk of injury or death to employees in the workplace. In addition, this revision of these requirements is reasonably necessary to provide protection from these hazards. The final rule becomes effective on August 13, 2007. As required by the Paperwork Reduction Act of 1995, the Federal Register notice for the Electrical Standard final rule stated that compliance with the collection of information requirements was not required until those collection of information requirements have been approved by OMB, and the Department of Labor publishes a notice in the Federal Register announcing that OMB approved and assigned a control number to the Electrical Standard collection of information requirements. Under 5 CFR 1320.5(b), an agency may not conduct or sponsor a collection of information unless: (1) The collection of information displays a current valid OMB control number; and (2) the agency informs members of the public who must respond to the collection of Start Printed Page 40074information that they are not required to respond to the collection of information unless the agency displays a currently valid OMB control number.

On February 14, 2007, OSHA submitted the Electrical Standard information collection request for the final rule to OMB for approval in accordance with the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). On May 22, 2007, OMB approved the collections of information contained in the final rule and assigned these collections OMB Control Number 1218-0256 titled “Design Safety Standards for Electrical Systems (29 CFR 1910.302-308 and 1910.399.)” The approval for these collections expires on May 31, 2010. The approved collections of information are:

A. Disconnecting Means and Circuits (§ 1910.303(f))

Section 1910.303(f)(5)(i)

Where circuit breakers or fuses are applied in compliance with the series combination ratings marked on the equipment by the manufacturer, the equipment enclosures shall be legibly marked in the field to indicate that the equipment has been applied with a series combination rating.

Section 1910.303(f)(5)(ii)

The marking required by paragraph (f)(5)(i) of this section shall be readily visible and shall state “Caution—Series Combination System Rated__Amperes. Identified Replacement Component Required.”

B. Branch Circuits (§ 1910.304(b))

Section 1910.304(b)(1)

Where more than one nominal voltage system exists in a building containing multiwire branch circuits, each ungrounded conductor of a multiwire branch circuit, where accessible, shall be identified by phase and system. The means of identification shall be permanently posted at each branch-circuit panelboard.

Section 1910.304(b)(3)(ii)(C)(1)

(C) Where the ground-fault circuit-interrupter protection required by paragraph (b)(3)(ii)(B) of this section is not available for receptacles other than 125-volt, single-phase, 15-, 20-, and 30-ampere, the employer shall establish and implement an assured equipment grounding conductor program covering cord sets, receptacles that are not a part of the building or structure, and equipment connected by cord and plug that are available for use or used by employees on those receptacles. This program shall comply with the following requirements:

(1) A written description of the [assured equipment grounding conductor (AEGC)] program, including the specific procedures adopted by the employer, shall be available at the jobsite for inspection and copying by the Assistant Secretary of Labor and any affected employee[.]

Section 1910.304(b)(3)(ii)(C)(6)

Tests performed as required in paragraph (b)(3)(ii)(C) of this section shall be recorded. This test record shall identify each receptacle, cord set, and cord- and plug-connected equipment that passed the test and shall indicate the last date it was tested or the interval for which it was tested. This record shall be kept by means of logs, color coding, or other effective means and shall be maintained until replaced by a more current record. The record shall be made available on the jobsite for inspection by the Assistant Secretary and any affected employee.[1]

C. Identification and Signs (§ 1910.306(c))

Section 1910.306(c)(6)(i)

Where there is more than one driving machine in a machine room, the disconnecting means shall be numbered to correspond to the identifying number of the driving machine that they control.

Section 1910.306(c)(6)(ii)

The disconnecting means shall be provided with a sign to identify the location of the supply-side overcurrent protective device.

D. Carnivals, Circuses, Fairs, and Similar Events (§ 1910.306(k))

Section 1910.306(k)(4)(iv)(B)

Single-pole separable connectors used in portable professional motion picture and television equipment may be interchangeable for ac or dc use or for different current ratings on the same premises only if they are listed for ac/dc use and marked to identify the system to which they are connected[.]

E. Documentation (§ 1910.307(b))

All areas designated as hazardous (classified) locations under the Class and Zone system and areas designated under the Class and Division system established after August 13, 2007 shall be properly documented. This documentation shall be available to those authorized to design, install, inspect, maintain, or operate electric equipment at the location.

F. Emergency Power Systems (§ 1910.308(b))

Section 1910.308(b)(3)(i)

A sign shall be placed at the service entrance equipment indicating the type and location of on-site emergency power sources. However, a sign is not required for individual unit equipment.

Section 1910.308(b)(3)(ii)

Where the grounded circuit conductor connected to the emergency source is connected to a grounding electrode conductor at a location remote from the emergency source, there shall be a sign at the grounding location that shall identify all emergency and normal sources connected at that location.
