OSHA requirements are set by statute, standards and regulations. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. This letter constitutes OSHA's interpretation of the requirements discussed. Note that our enforcement guidance may be affected by changes to OSHA rules. Also, from time to time we update our guidance in response to new information. To keep apprised of such developments, you can consult OSHA's website at http://www.osha.gov.

Dear Mr. Hitchings:
This is in response to your letter requesting a clarification of the OSHA Standard [1926.405(a)(2)(ii)(G)] as temporary versus portable lighting.
Portable lighting is considered battery operated equipment and is limited to 12 volts as indicated in [1926.405(a)(2)(ii)(G)]. Temporary lighting may be used in explosive atmospheres as long as it meets all the requirements stated in the National Electrical Code NFPA 70 1971. This includes explosion proof, screened lighting sources with continuous wiring without male and female plugs inside the confined space designated.
Please feel free to contact us it there are further questions about OSHA.
