What is the proper method for identifying energy sources before applying LOTO?

Conducting a thorough energy audit is the proper method for identifying energy sources before applying Lockout/Tagout (LOTO). An energy audit involves systematically reviewing all potential energy sources associated with a piece of equipment or machinery. This includes identifying electrical, mechanical, hydraulic, pneumatic, thermal, and other forms of energy that could pose a risk during servicing or maintenance operations.

By performing an energy audit, workers can accurately determine how various systems operate and the potential hazards associated with them. This comprehensive approach helps ensure that all energy sources are properly managed, preventing unexpected releases of energy that could result in serious injuries or fatalities during maintenance work.

Relying on guessing based on experience, referring to the manufacturer’s manual, or simply asking other employees may not provide a complete or accurate identification of all energy sources. Each of these alternatives could lead to critical oversights, leaving workers vulnerable to unrecognized hazards. Thus, the thorough energy audit stands as the most reliable and effective method for ensuring safety in the workplace during LOTO procedures.
