Dear Mr. Hudnall:
This is in response to your February 28 letter, requesting clarification on whether the Process Safety Management (PSM) of Highly Hazardous Chemicals standard, 29 CFR 1910.119 applies to the following workplace application.
Scenario: Bell Helicopter Textron Inc. has a heat treating process which uses a combination of methanol and propane solely to fuel furnace/ovens used to heat metal parts such as gears. This process does not include any other chemicals covered by the PSM standard.
Reply: The process described in the scenario above would not be covered by the PSM standard which excepts hydrocarbon fuels, including methanol and propane, used solely for workplace consumption as fuel. (See 1910.119(a)(ii)(A)).
Thank you for your interest in occupational safety and health. If we may be of further assistance please contact us.
