Standardized Safety Practices and Procedures

DOE-HDBK-1092-2004

Consistent with other sections of this document, electrical systems and equipment and all

design, development, fabrication and construction, modification, installation, inspection, testing,

operation, and maintenance shall be in accordance with applicable electrical requirements.

Specific attention shall be focused on the electrical regulations of OSHA, including:

1. 29 CFR 1910.137

2. 29 CFR 1910.147

3. 29 CFR 1910.269

4. 29 CFR 1910.301-399

5. 29 CFR 1926.401-449.

10.4 STANDARDIZED SAFETY PRACTICES AND PROCEDURES

Standardized safety practices shall be developed for performing electrical work. These practices

should be consistent with the other electrical safety-related work practices noted elsewhere in

this document.

10.5 EQUIPMENT NOT LISTED BY A NATIONALLY RECOGNIZED

TESTING LABORATORY

10.5.1 HAZARDS

Electrical equipment is considered to be acceptable either by being listed by an NRTL,

designed, manufactured, and tested according to nationally recognized standards, or approved

by AHJ-determined criteria. Refer to Section 2.5, Approval of Electrical Equipment.

Procurement and use of equipment not listed by an NRTL should be reviewed by the AHJ. The

extensive testing involved in the listing process usually cannot be duplicated at the user facility,

and many of the tests are destructive in nature. The AHJ should develop an examination

acceptance process to ensure appropriate confidence in the safety of the product.

See Section 9.0, Enclosed Electrical/Electronic Equipment, for additional guidance. Also see UL

508 and applicable ANSI and IEEE documents.

10.5.2 DESIGN AND CONSTRUCTION

Equipment should be constructed such that:

1. There is adequate protection from fire, electric shock, or injury to personnel during normal

use or servicing.

2. Normal use or servicing will not cause the components or materials to exceed electrical,

mechanical, or temperature limits.

3. The components, wiring, and other internal parts are protected from being displaced or

damaged.
