Process safety management (PSM) is a critical aspect of workplace safety, aiming to prevent incidents involving highly hazardous chemicals (HHCs). The Occupational Safety and Health Administration (OSHA) has established the PSM standard to address this issue, providing a framework for industries that handle HHCs to implement effective safety measures.
Key Facts
- Definition of a PSM-covered process: According to 29 CFR 1910.119(b), a process is defined as any activity involving a highly hazardous chemical, including its use, storage, manufacturing, handling, or on-site movement.
- Purpose of PSM: The main goal of the PSM standard is to prevent mishandling or accidental releases of highly hazardous chemicals, which can lead to catastrophic incidents and serious worker injuries.
- Applicability: The PSM standard applies to industries that use highly hazardous chemicals, including manufacturing, construction, electric, gas, and sanitary services, farm product warehousing, natural gas liquids, pyrotechnics and explosives manufacturers, and wholesale trade.
- Chemical quantities: The PSM requirements apply to companies that deal with more than 130 specific reactive and toxic chemicals in listed quantities, as well as flammable gases and liquids in quantities of 10,000 pounds or more.
- Exceptions: The PSM standard does not apply to retail facilities, oil or gas well drilling or servicing operations, and normally unoccupied remote facilities.
PSM-Covered Processes: A Definition
According to 29 CFR 1910.119(b), a PSM-covered process is defined as any activity that involves a highly hazardous chemical, encompassing its use, storage, manufacturing, handling, or on-site movement. This definition highlights the broad scope of PSM coverage, ensuring that various activities involving HHCs are subject to the standard’s requirements.
Purpose of PSM
The primary objective of the PSM standard is to prevent mishandling or accidental releases of highly hazardous chemicals. These incidents have the potential to cause catastrophic events, resulting in severe worker injuries, environmental damage, and public health risks. By implementing PSM measures, industries can proactively identify and mitigate hazards associated with HHCs, reducing the likelihood of such incidents.
Applicability of PSM
The PSM standard applies to a wide range of industries that utilize highly hazardous chemicals. These industries include manufacturing, construction, electric, gas, and sanitary services, farm product warehousing, natural gas liquids, pyrotechnics and explosives manufacturers, and wholesale trade. The standard’s applicability is driven by the presence of HHCs in these industries, recognizing the potential risks associated with their handling.
Chemical Quantities
The PSM requirements are triggered by the quantities of HHCs present in a facility. Companies that deal with more than 130 specific reactive and toxic chemicals in listed quantities, as well as flammable gases and liquids in quantities of 10,000 pounds or more, are subject to the PSM standard. This threshold ensures that industries with significant amounts of HHCs are required to implement PSM measures.
Exceptions to PSM Applicability
The PSM standard does not apply to certain facilities or operations. Retail facilities, oil or gas well drilling or servicing operations, and normally unoccupied remote facilities are exempt from the standard’s requirements. These exceptions are based on the lower risk profile associated with these activities or the limited presence of HHCs.
Conclusion
Process safety management plays a vital role in preventing incidents involving highly hazardous chemicals. The PSM standard, established by OSHA, provides a comprehensive framework for industries that handle HHCs to implement effective safety measures. By understanding the definition, purpose, applicability, and exceptions of PSM-covered processes, industries can ensure compliance with the standard and prioritize the safety of their workers and the surrounding community.
