Module 5.3: Lock Boxes and Multi Lock Hasps

Lock Boxes and Multi Lock Hasps are tools used in group Lockout/Tagout procedures to ensure multiple workers can safely control hazardous energy while servicing the same equipment. You will learn how these devices allow each worker to apply their own personal lock, ensuring the equipment cannot be re-energized until everyone has completed their work. Using these systems helps maintain accountability and ensures that all workers remain protected throughout the maintenance process.

• Lock boxes store the keys to energy isolation locks during group lockout procedures.

• Each worker applies their personal lock to the lock box to maintain individual protection.

• Multi lock hasps allow multiple locks to be applied to a single energy isolation device.

• Equipment cannot be restarted until every worker has removed their personal lock.

• These tools help coordinate group maintenance tasks while maintaining strict energy control.
