Process Hazard Analysis (PHA) studies are a thorough, systematic approach for identifying, evaluating, and controlling the hazards of processes involving highly-hazardous chemicals, as required by the Occupational Health & Safety Association (OSHA).
As companies need to perform an initial hazard evaluation on all processes covered by this standard, MISTRAS’ experienced consultants have the technical expertise and industry knowledge to support them.
MISTRAS helps our clients first determine and document the priority order for conducting PHA, based on the extent of the process hazards, the number of potentially-affected employees, the age of the process, and the operating history of the process. PHAs must be updated and re-validated at least every five years.
The PHA methodology selected must be appropriate to the complexity of the process and must identify, evaluate, and control the hazards involved in the process. All PHAs must address multiple factors, including:
- Hazards of the process
- Identification of any previous incident that had a potential for catastrophic consequences in the workplace
- Consequences of failure of engineering/administrative controls
- Facility siting
- Human factors
- Qualitative evaluation of a range of the possible safety/health effects on the workforce if there is a failure of controls
Once the PHA is completed, MISTRAS supports our clients in addressing PHA findings/recommendations; ensuring that the recommendations are resolved in a timely manner; and documenting, maintaining, and communicating findings to employees whose work assignments may be affected by the PHA recommendations or actions.
