Dear Mr. Orth:

This is in response to your July 20 letter requesting clarification of the Process Safety Management (PSM) of Highly Hazardous Chemicals, 29 CFR 1910.119, standard. Hydrocarbon fuels, including propane and natural gas, used solely for workplace consumption, for example to heat the bakery ovens described in your letter, are not covered by the PSM standard. Please note that bakery ovens are covered by the bakery equipment standard at 29 CFR 1910.263.

Thank you for your interest in occupational safety and health. If we may be of further assistance please contact us.

Sincerely,



Roger A. Clark, Director
Directorate of Compliance Programs
