Process Safety Management (PSM) is the prevention or minimisation of release of highly hazardous chemicals to Major Hazard Sites. Major Hazard Sites are industrial sites that manufacture, process or store dangerous chemicals and substances in quantities that could pose a risk to workers, people in the vicinity of the site, and the environment in the event of a major accident.
These “major accidents” include fires, explosions or incidents in which dangerous substances are released.
Major accidents are rare, but can occur at sites ranging from large petrochemical plants to chemical storage warehouses. This element assist in the management of a number of technical, managerial and human factors activities which, if not managed effectively, may lead to a major accident in future.
