PROCESS HAZARD ANALYSIS (PHA)

Process Hazard Analysis/Hazard Review is a thorough, orderly and systematic approach for identifying, evaluating, and controlling the hazards of processes involving highly hazardous chemicals. Facilities are required to review the hazards associated with the regulated substance(s) to identify possibilities of equipment malfunction or human error, and the steps needed to monitor or detect releases. 

A PHA is required every five (5) years or sooner if the facility incurs a major change (40 CFR 68.50(d) & 68.67(f) and 29 CFR 1910.119) for facilities under PSM/RMP. 

 

Both OSHA’s and EPA’s General Duty Clauses require facilities to identify the hazards using appropriate hazard assessment techniques which is what the PHA/HR provides. The frequency is to complete an initial and when there are changes to the system, personnel changes and accident history.

The PHA/HR should identify all failure scenarios that could lead to significant ammonia exposure of workers, the public, or the environment. 

 

Protexus PHA/HR leaders are knowledgeable in the What-If/Checklist and HAZOP methodologies utilized in the industry.

 

Our PHA leaders can lead PHA/HRs for design, initial, and re-validations. We develop and provide the facility with a tracking and prioritization system to resolve PHA findings.
