What hazard control procedures may be required for electrical, pneumatic, hydraulic, or mechanical energy hazards?

The correct answer focuses on "LOTO/COHE procedures," which stands for Lockout/Tagout and Control of Hazardous Energy. This is a critical safety protocol used when working with machinery or equipment that could release hazardous energy during servicing or maintenance.

These procedures ensure that the equipment is properly shut down and inoperable before any maintenance or work starts. The lockout aspect involves physically locking the machinery in a safe state to prevent accidental engagement, while tagging informs others that the equipment is not to be operated. This is particularly important when dealing with electrical, pneumatic, hydraulic, or mechanical energy hazards where sudden release can lead to serious injuries or fatalities.

Isolation procedures are relevant but are a broader category that may not necessarily involve the specific actions required by LOTO. Confined space assessments are crucial for identifying the risks within confined spaces but do not directly control energy hazards. Ventilation processes are also important for managing air quality in confined spaces but do not directly relate to the isolation or control of energy sources. The specificity of LOTO/COHE procedures makes them essential for controlling energy hazards effectively during maintenance activities.
