DOE O 420.1A, FACILITY SAFETY, identifies safety analysis requirements for various types
of facilities and requires consideration of natural phenomena hazards relative to facility sitting.
DOE O 440.1A, WORKER PROTECTION MANAGEMENT FOR DOE FEDERAL AND
CONTRACTOR EMPLOYEES, describes general hazard identification and analysis
requirements for occupational safety and health.
Emergency Planning DOE O 151.1B, COMPREHENSIVE EMERGENCY MANAGEMENT
SYSTEM, requires hazard identification as the basis for emergency planning. PrHAs have direct
application for identifying chemical process hazards in support of emergency planning as
required by DOE O 151.1B. They should be used to support the emergency planning element in
the PSM Rule in conjunction with consequence modeling. PrHAs, SARs, and emergency
planning hazard analyses should be combined to satisfy all program requirements whenever
MOC If the PrHA identifies an issue that leads to a change in procedures, drawings, or design,
the change must be submitted through the facility's MOC systems. If the PrHA identifies an
issue that falls outside the safety envelope for a facility, that issue should be treated as a potential
unreviewed safety question as described in 10 CFR 830 Subpart B NUCLEAR SAFETY
MANAGEMENT, SAFETY BASIS REQUIREMENTS and DOE G 424.1-1,
IMPLEMENTATION GUIDE FOR USE IN ADDRESSING UNREVIEWED SAFETY
Written PrHAs, updates and revalidations, and documentation of resolutions to recommendations
must be kept for the life of a process and reviewed every five years. The PrHA may be a
stand-alone document or an attachment used in conjunction with facility safety documentation. A
PrHA report should identify the PrHA team members, the processes analyzed, the PrHA method
used, and the manner in which required PrHA issues were addressed. Other documentation to
support the review depends on the method selected, the covered process, and the particular needs
of the facility [Q53].
Minimum Implementation Criteria
This section provides a summary of the minimum implementation criteria for the PrHA element.
DOE-HDBK-1100-96, Chemical Process Hazards Analysis, addresses the PrHA element of the
PSM Rule in detail.
Schedule PrHAs must be completed by risk-priority, based on a relative ranking of the risks of
the covered processes [Q54]. This ranking must consider the extent of the process hazards, the
number of potentially affected employees, the age of the process, and the operating history of the
process. The basis for this ranking must be documented [Q55]. DOE contractors must complete
the required PrHAs prior to process startup [Q56]. PrHAs must be reviewed and updated at least
every 5 years and retained for the life of the process [Q57,Q58,Q59].
Team PrHAs must be performed by a team having the following mandatory qualifications.
