What is meant by "residual energy" in the context of LOTO?

• A. Energy that has dissipated completely
• B. Energy that remains after shutdown
• C. Energy stored in batteries only
• D. Energy generated during operation

Answer: (B)

In the context of Lockout/Tagout (LOTO), "residual energy" refers to the energy that remains in a system after it has been shut down. This energy can be in the form of potential energy stored in mechanisms, hydraulic pressure, pneumatic pressure, or even electricity in capacitors. Understanding residual energy is critical for ensuring safety during maintenance and servicing, as it could lead to unexpected movement, equipment operation, or release of hazardous materials if not properly controlled. When implementing LOTO procedures, it is essential to identify and address residual energy to protect workers, ensuring that all sources of energy that could lead to re-energization or movement of equipment are effectively isolated and controlled. This concept is fundamental to maintaining a safe working environment under the LOTO standard.
