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 https://www.osha.gov.

Special Assistant, Personnel
The Potomac Edison Co.

Dear Mr. Hoak:

This is in response to your letter dated June 10, 1975 requesting an interpretation of a construction standard.

Section 1926.902(d) of the OSHA construction standards does not apply to over the highway transportation of explosives. The Department of Transportation has jurisdiction in that area and permits under 49 CFR 177.835(g) the simultaneous transportation of blasting caps with other explosives on the same vehicle under certain conditions.

Your interest in occupational safety and health is appreciated.

Sincerely yours,

Assistant Regional Director for
Occupational Safety and Heath
