The Process Hazard Analysis (PHA) technique was created to help evaluate the risks of chemicals and processes in an objective, quantitative manner. PHA documents are often required for high risk industries like the chemical and manufacturing industries where accidents can have catastrophic effects on workers, the environment and/or the public. The PHA technique is used by engineers, project managers, management to determine potential control hazards before they occur using a ranking system such as: Risks are assessed in terms of likelihood (i.e., likely to happen, likely to cause major damage if it does), severity (i.e., how serious the consequences would).
