Chain Block Lifting

This Standard Operating Procedure (SOP) outlines essential safety practices for using chain blocks in lifting operations. It covers risks associated with chain block and anchor failures, free-fall incidents, and improper use beyond rated workload limits. This document is crucial for operators and safety officers to ensure compliance with Australian WHS legislation and to prevent injuries in the workplace.

• Chain block failure or anchor failure → load drop and fatality
• Free-fall of load on brake failure
• Sudden release of stored energy in lever blocks (kick-back) → struck-by
• Use beyond rated WLL
• Side-loading or off-axis pull → distortion of hooks and frame
• Hand and finger injuries from the hand chain or load chain
• Pinch points at hook latches and chain wheels
• Use of a damaged or modified block
