2025 Second Alert LTI#03 HiPo#11 Fell From Height
On 2nd March 25 at approximately 12:30hrs, a crane auxiliary hook block came out from its original position when crane operator was extending the boom at 60 degree angle causing it to swing and land on the crane boom (retained by the jumper pin). The crane operator then lowered the boom to zero angle to investigate the defect. The crane operator then climbed onto the boom, with site supervisor knowledge, inspected the defect and decided to remove the jumper pin so he could drop the auxiliary hook block to the ground. While doing so, the auxiliary hook block (95Kg), connected with its wire, dropped to the ground dragging the crane operator’s right foot which resulted in him falling from a height of 3.2 meters. Emergency response was initiated to transfer the IP to PAC clinic. The crane operator sustained fracture injuries to his leg and wrist
How am I ensuring that my supervision effectively manages all operational risks during this task? Have I applied all 7 steps of Musta’ed to this specific task before starting? Has the crane operator inspected the limit switch, and have I personally assured its functionality before operation? I s the crane operator maintaining a safe length of the auxiliary hook block prior to boom extension? Are all crew members complying with life-saving rules, and how am I enforcing them consistently? Are all crew members using safe means of working at height?
Crane operator didn’t lower/maintain enough length of auxiliary hook block prior to extending the boom. Crane operator trusted the limit switch to activate avoiding the block from reaching the sheave instead of following safe operational practices. Crane operator decided to troubleshoot and recover the block instead of reporting to maintenance/recovery crew. Limit switch safety device of auxiliary hook block failed to trip the crane motion before reaching the crane sheave. Dynamic risk review was not conducted after the first event (auxiliary hook block came out from its original position). Crane operator worked at height without fall protection or use of working at height equipment/ platform Site leadership did not enforce life saving rules compliance. Stop work authority was not exercised by crew members.
