• Identify all gravity and suspended load hazards during the pre-task risk assessment
• Lower raised components to a safe position before starting maintenance wherever possible
• Install rated mechanical supports, props, or pins to prevent movement of raised parts
• Include gravity isolation as a specific item on every LOTO permit for affected equipment
• Verify the mechanical restraint is secure and load-bearing before working beneath any component
• Use manufacturer-specified support devices and follow the equipment maintenance manual
• Brief all workers on the gravity hazards and the isolation measures in place before starting
• Never rely on hydraulic pressure alone to hold a raised component during maintenance
• Inspect mechanical supports for damage and correct rating before each use
• Remove mechanical supports only after all workers are clear and re-energisation is authorised

• DON'T work beneath raised components without rated mechanical supports in place
• DON'T rely on hydraulic or pneumatic pressure to hold loads — use mechanical blocking
• DON'T forget gravity energy when completing LOTO assessments for equipment maintenance
• DON'T use improvised props such as timber or bricks to support heavy equipment parts
• DON'T remove safety pins or mechanical supports while anyone is beneath the component
• DON'T assume a component will stay in position because it has not moved for a while
• DON'T skip the physical verification that mechanical supports are correctly installed
• DON'T begin maintenance until the permit confirms gravity energy has been isolated
• DON'T use supports rated below the weight of the component they are restraining
• DON'T overlook spring-loaded mechanisms which store energy even when equipment is off
