Why is it important to dissipate or restrain stored energy during lockout/tagout?

Dissipating or restraining stored energy during lockout/tagout is crucial primarily to ensure that equipment cannot start unexpectedly. When maintenance is being performed, any stored energy—such as electrical, mechanical, hydraulic, or pneumatic energy—presents a significant risk. If this energy is not properly managed, equipment might activate while workers are still interacting with it, potentially leading to serious injuries or fatalities.

By effectively dissipating or restraining this energy, workers can create a safer environment, reducing the likelihood of accidental machinery start-ups or releases of hazardous energy. This practice aligns with OSHA standards, which are designed to protect worker safety during service and maintenance operations.

While other options may involve factors of convenience or efficiency, the top priority must always be worker safety, making the management of stored energy a critical component of the lockout/tagout process.
