Lockout/Tagout & De-Energization
LOTO Requirements
Lockout/tagout (LOTO) requires operators to de-energize and secure equipment before maintenance. This means shutting down the engine, engaging the parking brake, lowering all implements to the ground, relieving hydraulic pressure, removing the key, and placing a personal lock on the controls. LOTO prevents accidental startup while maintenance personnel are working on or under the machine.
Hydraulic Lockout
Hydraulic lockout specifically disables controls during maintenance to prevent movement. Even with the engine off, stored hydraulic pressure or gravity can cause booms, arms, and buckets to move unexpectedly. Hydraulic lockout may involve engaging mechanical locks, safety pins, or blocking cylinders with supports.
Stored Energy Hazard
Hydraulic systems can retain thousands of PSI of pressure even after shutdown. Always relieve pressure and verify zero energy state before performing any maintenance near hydraulic components.
Lockout/tagout requires de-energizing and securing equipment before maintenance. Hydraulic lockout disables controls to prevent movement from stored pressure or gravity.
