Minimum Implementation Criteria cont'd

DOE-HDBK-1101-96

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 com-

plexity 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 appro-

priate 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 recommenda-

tions; 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 siting 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 investigation

provision of this Rule, contractors are required to retain incident reports for 5 years, the time be-
