Minimum PHA Method Requirements
No matter which PHA method you use, it must meet the following minimum requirements to be effective.
The PHA must analyze the hazards of a process.
Each method must:
- address the hazards of the process;
- identify any previous incident that had a potential for catastrophic consequences in the workplace;
- determine engineering and administrative controls applicable to the hazards and their interrelationships, such as appropriate application of detection methods 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);
- identify the consequences of failure of engineering and administrative controls;
- address facility siting;
- address human factors; and
- conduct 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.
