A process hazard analysis is a thorough, orderly, systematic approach for identifying, evaluating, and controlling the hazards of processes involving highly hazardous chemicals.

Process hazard analysis is best performed by a team with expertise in engineering and process operations.

The following methods are frequently used, as appropriate, to determine and evaluate the hazards of the process being analysed:

  • What-if;
  • Checklist;
  • What-if/checklist;
  • Hazard and operability study (HAZOP);
  • Failure mode and effects analysis (FMEA);
  • Fault tree analysis; or
  • An appropriate equivalent methodology.

Process hazard analysis must address the following:

The hazards of the process;

The identification of any previous incident that had a potential for catastrophic consequences in the workplace;

Engineering and administrative controls applicable to the hazards and their interrelationships, such as appropriate application of detection methodologies to provide early warning of releases. Acceptable detection methods might include process monitoring and control instrumentation with alarms, and detection hardware such as hydrocarbon sensors;

Consequences of failure of engineering and administrative controls;

Facility siting;

Human factors; and

A qualitative evaluation of a range of the possible safety and health effects on employees in the workplace if there is a failure of controls.
