What are "process deviations" in the context of PSM?

In the context of Process Safety Management (PSM), "process deviations" refer to unforeseen changes in processes that can introduce risks. These deviations can occur due to variations from established operating conditions, abnormal situations, or unexpected events that affect the safety and integrity of the process. Understanding process deviations is crucial because they can lead to hazardous situations if not properly managed.

When a process deviates from its normal operating conditions, it can result in unsafe situations such as leaks, equipment failures, or even accidents. Therefore, identifying, analyzing, and addressing these deviations is essential for maintaining safe operations and preventing incidents. Effective PSM practices involve monitoring processes and having controls in place to detect and respond to these deviations swiftly before they lead to significant safety issues.

In contrast, the other options represent different aspects of operations: planned changes in workflow are typically controlled and managed rather than unforeseen; standard operating procedures are established protocols for conducting work safely; and regular maintenance checks are part of routine preventative measures to ensure equipment operates correctly but do not specifically address process deviations.
