DOE-HDBK-1101-2004
At least one individual with expertise in engineering and process operations.
At least one individual with specific process experience.
A team leader knowledgeable in the methodology.
A PrHA team is usually composed of two to five members and may include a safety engineer or
analyst, a process engineer, a maintenance supervisor, a operations supervisor, a facilities
engineer, or other members with needed expertise. At a minimum, the team leader should be able
to properly and impartially use the selected PrHA methodology. There are no specific
requirements for PrHA leader qualifications or for documenting the qualifications of team
members. However, brief resumes of team members should be included in PrHA documentation.
Detailed classroom training on PrHA methods is an appropriate way for team members to gain
knowledge about specific PrHA methods. Contractors may elect to compile a list of
PrHA-qualified individuals at a facility along with their PrHA experience [Q48].
Method Selection of an appropriate PrHA method depends on several factors including the
complexity of a process, historical and industry information about the process, and process
stability. Selection of the methodology must be consistent with the process being analyzed. One
or more of the following methodologies, or an appropriate equivalent methodology, must be
used. The PSM Rule allows other equivalent analysis methodologies to be used if they are
systematic and appropriate for the level of complexity of the process [Q47].

DOE contractors should refer to appropriate industry references such as CCPS's Guidelines for
Hazard Evaluation Procedures, Second Edition with Worked Examples for more information
about appropriate, equivalent PrHA methodologies. Descriptions of PrHA methods are also
provided in DOE-HDBK-1100-96, Chemical Process Hazards Analysis. The PrHA process is
generally divided into three phases: information gathering; conduct of the PrHA and
development of recommendations; and resolution. PSI should be developed prior to initiating a
PrHA or as part of the PrHA process.
During the PrHA, the team must identify process hazards; review the accident history of the
process to identify process hazards, accident precursors, lessons learned, and trends; consider the
impacts of human factors; identify engineering and administrative control measures and their
interrelationships; determine the consequences if those control measures fail, taking facility
sitting into consideration; and determine the qualitative range of safety and health effects on
employees at the worksite [Q49]. In developing the PrHA, the team must consult with any
subcontractor employees involved in the operation or maintenance of the process.
The PSM Rule requires DOE contractors to address in the PrHA previous incidents at their
facilities that had a potential for catastrophic effects in the workplace. Under the incident
