Incident Overview HSE describes an incident where failure of a hookloader lifting arm led to the skip disconnecting and being ejected, fatally injuring a worker. This is a lifting/handling interface failure with the same end result: a heavy container becomes uncontrolled. What Went Wrong Mechanical failure occurred during handling Unsafe operating method contributed (jogging/shock actions) People were exposed within the hazard zone Key Lessons Learned “Container handling” is still lifting risk Mechanical failures need strict exclusion zones Shock actions multiply failure likelihood Safety Recommendations Maintain hookloader lifting systems, ban “jogging” methods, keep people out of the hazard zone, and treat container ejection as a catastrophic foreseeable risk. Incident source HSE guidance example on skip ejection after lifting arm failure. hse.gov.uk ●LOLER Reg. 4 – Loads must remain secure. ●LOLER Reg. 8 – Lifting must be controlled and supervised. ●PUWER Reg. 5 – Mechanical systems must be maintained. ●BS 7121-1 – Containers/skips must be handled safely. Key point Ejection risk is foreseeable and fatal. Wolf Lifting Dynamics – Safe Lifting UK | Case Study 98

Incident Overview A tower crane collapse in Crewe resulted in three fatalities. Years later, the incident continues to drive legal proceedings and formal findings. What Went Wrong High-consequence failures usually expose weaknesses in governance: competence, procedure, inspection, supervision, and change control. Key Lessons Crane governance failures kill Decisions made weeks earlier can be causal Documentation becomes evidence Safety Recommendations Strengthen governance: erection/alteration controls, inspections, competence, stop authority, and “paper-to-field” checks. Incident source/ Reference Inquest/news coverage and HSE roundup references. https://www.constructionenquirer.com ●LOLER Reg. 4 – Integrity and stability are fundamental duties. ●LOLER Reg. 8 – Planning, supervision and safe execution required. ●LOLER Reg. 9 – Examination/inspection regime must be effective. ●PUWER Reg. 5 – Maintenance and defect control required. ●BS 7121-1 – Crane management system must control change and risk.

Incident Overview An offshore crane boom collapsed catastrophically during operations, creating a chaotic scene and secondary hazards (debris, damaged equipment, uncontrolled energy). What Went Wrong Mechanical integrity failed. Offshore lifting adds consequences due to confined layouts, simultaneous operations, and high-energy components. Key Lessons Integrity management is a safety system Secondary hazards after failure are lethal “No injury” is luck, not compliance Safety Recommendations Robust maintenance regimes, inspection intervals, defect reporting, and stop-work authority when integrity is in doubt. Incident source/ Reference HSE roundup referencing offshore crane boom collapse prosecution. press.hse.gov.uk ●LOLER Reg. 4 – Strength and stability must be ensured. ●LOLER Reg. 9 – Examination must identify defects in time. ●PUWER Reg. 5 – Maintenance must prevent catastrophic failure. ●PUWER Reg. 4 – Equipment must remain suitable for conditions. ●BS 7121-1 – Defect reporting and stop-work must be effective.

Incident Overview A luffing jib tower crane jib collapse occurred on a residential project in Edinburgh, causing injuries and triggering an investigation. What Went Wrong Crane structural events are rarely single-cause. They usually involve a chain: configuration, inspection, wind/operations planning, and oversight. Key Lessons Crane structural events are multi-factor Erection/alteration controls must be watertight Wind planning and safe-out-of-service matters Safety Recommendations Strict crane governance: documented inspections, tie/erection verification, wind controls, and clear stop rules. Incident source/ Reference Edinburgh luffing crane collapse reported in industry press. Constructionmanagement.co.uk ●LOLER Reg. 4 – Stability and integrity are mandatory. ●LOLER Reg. 8 – Safe planning and supervision required. ●LOLER Reg. 9 – Examination/inspection regime must be effective. ●PUWER Reg. 5 – Maintenance systems must prevent failure. ●BS 7121-1 – Governance of erection/alteration/operation must be controlled.

Incident Overview A luffing jib tower crane jib collapsed at a London development site. The site was unoccupied at the moment, avoiding injury, but it triggered emergency response and public safety controls. What Went Wrong Even when no one is hurt, this is a serious indicator: a collapse event means the system failed somewhere — inspection, configuration, weather planning, or structural integrity. Key Lessons “No injury” is not “no incident” Near-miss collapses demand full investigation Public interface changes everything Safety Recommendations Treat as a major incident. Secure area, preserve evidence, formal investigation, and review wind/erection/tie/inspection arrangements. Incident source/Reference Central Middlesex Hospital development crane jib collapse reported in London. www.chiswickcalendar.co.uk ●LOLER Reg. 4 – Strength and stability must be maintained. ●LOLER Reg. 9 – Thorough examination must be in place where required. ●PUWER Reg. 5 – Maintenance must prevent dangerous failure. ●BS 7121-1 – Crane management arrangements must be robust. ●CDM 2015 – Public interface and emergency controls must be considered.
