Which item is NOT typically included in safety-critical steps of an SOP?

• A. Lockout/Tagout procedures
• B. Required PPE
• C. Equipment maintenance schedule
• D. Safe work methods

Answer: (C)

Safety-critical steps are the actions you must perform during a task to prevent immediate harm, establish proper control, and ensure the task is done safely. Lockout/Tagout procedures are a guardrail to ensure energy sources are isolated before work, preventing unexpected energization. RequiringPersonal Protective Equipment is a direct safety control, giving you protection against specific hazards encountered during the task. Safe work methods lay out the approved sequence and precautions for performing the task safely, guiding workers through risk-reducing steps in real time.

An equipment maintenance schedule, by contrast, focuses on when to inspect, service, or replace machinery to keep it reliable and reduce the chance of future failures. It’s about maintaining equipment health over time rather than the immediate safety actions taken during the task. Because of that, it isn’t typically listed as part of the safety-critical steps you follow while performing the operation, though it supports safety indirectly through better equipment condition.
