Dear Mr. Ludlow:

Thank you for your letter of March 5, addressed to Acting Assistant Secretary Dorothy Strunk, concerning the application of the Occupational Safety and Health Administration's (OSHA) standard, "Process Safety Management of Highly Hazardous Chemicals" with respect to the manufacture of explosives and pyrotechnics.

Specifically, you stated that the manufacture of explosives and pyrotechnics for government agencies is tightly controlled by DoD and the customer agency. You inquired if OSHA would consider these manufacturers as being under the jurisdiction of another federal agency and therefore exempt from the process safety standard.

OSHA would not consider contractor-owned contractor-operated (COCO) munitions facilities to be under the jurisdiction of another federal agency because these agencies have not exercised regulatory authority over worker protection in a manner sufficient to preclude OSHA coverage under section 4(b)(1) of the Occupational Safety and Health Act of 1970. Consequently, COCO manufacturers of explosives and pyrotechnics for government agencies would not be exempt from the process safety standard.

I hope this information will be of assistance to you.

Sincerely,



Roger A. Clark
Director, Directorate of
Safety Standards Programs
