Process Hazard Analysis - doe-hdbk-1101-20040043


DOE-HDBK-1101-2004
PSI should contain a description of the function and design basis for all ventilation
systems whose purpose is to maintain a healthy environment, particularly when these
ventilation systems are used to maintain a safe haven in the event of a catastrophic
release of a HHC.
PSI should contain a functional description of the safety systems in a covered process.
Safety systems are systems designed to control and maintain a process within safe design
parameters. Examples of safety systems are interlocks, scrubbers, flares, and detection
systems for releases of toxic or flammable chemicals. Workers should know what
protective features exist and how to use these safety systems in an emergency.
Chemical hazard information should contain information on the incompatibility of HHCs
with materials that are known to exist in the workplace. Employees routinely working
with materials commonly found around a covered process should be familiar with the
potential safety and health impacts from inadvertently combining these materials with the
HHC.
44.
Do we have to keep hard copies of all of the PSI or can we use electronic media?
There is no specific storage requirement for PSI or any other documentation created
under the PSM Rule. Any medium may be used as long as the accessibility requirements
are met. However, DOE contractors who use electronic storage media should consider in
advance what they will do when computers used to access this information are
unavailable (e.g., during power failures).
45.
How long must DOE contractors maintain process safety information?
To demonstrate compliance and to meet the intent of the PSM Rule, PSI must be kept for
the lifetime of a process and updated whenever changes other than replacement in kind
are made.
46.
How can a PrHA be used to demonstrate that equipment is designed safely?
The PrHA can be used to perform a sensitivity analysis to evaluate the impacts of using
equipment or facilities which have not been designed to current codes and standards.
