Dear Mr. Schuchman:
This is in response to your September 20, 1994 letter requesting an interpretation of the process safety management (PSM) of highly hazardous chemicals standard, 29 CFR 1910.119. Specifically, you requested clarification on the exception under paragraph 1910.119(a)(1)(ii)(B) as it applies to flammable liquids stored in atmospheric tanks or transferred which are kept below their normal boiling point without benefit of chilling or refrigeration. Please accept our apology for the long delay in responding.
The exception under paragraph 1910.119(a)(1)(ii)(B) is applicable to a process that only includes the activities of storage and associated transfer of flammable liquids under the conditions noted above. This exception would not be applicable to a process which includes any one or combination of the following flammable liquid activities: use, storage (other than described previously), manufacturing, handling, or on-site movement and also storage in atmospheric tanks and associated transfer which are kept below their normal boiling point without the benefit of chilling or refrigeration. See the definition of process under paragraph 1910.119(b). For the purposes of this definition, any group of vessels which are interconnected and separate vessels which are located such that a highly hazardous chemical, including a flammable liquid, could be involved in a potential release are considered a single process.
We appreciate your interest in occupational safety and health. If we can be of further assistance, please contact Mr. Ronald J. Davies of my staff at telephone (202) 219-8031, extension 110.
Raymond E. Donnelly, Director
