No. Unlike various other environmental, health, and safety regulations, the PSM standard does not have notification or reporting requirements. This means employers do not need to inform OSHA whether or not they meet the PSM applicability criteria. They need only ensure that they fully comply with the mandatory PSM requirements for all processes that meet the applicability criteria. Out of caution, some employers may choose to implement these elements in processes that use highly hazardous chemicals in quantities that do not exceed the applicability criteria — but this is not required.
