PSM requires employers to perform a process hazard analysis of every process involving usage & production of hazardous chemicals. Hazard analysis must be performed as per documented priority list which can be based upon several factors such as number of potentially affected employees, age of the process, history of the process, etc.
Every five years you are required to reevaluate and revalidate your Process Hazard Analysis. A PHA is also required when you install new equipment or modify existing systems. This can be the perfect time to call Industrial Consultants to help you through the process.
