Case Study 57: Single-Use Strap Used to Lift Sharp Peri Shutters
Incident Overview Sharp-edged Peri shutters were lifted using a single-use strap above a live construction site. What Went Wrong Incorrect lifting accessory selection. Key Lessons Learned - Sharp loads require edge protection - Single-use straps are limited - No lifting if there's no lifting accessories available Safety Recommendations Correct lifting accessories must be selected based on load type. ●LOLER 1998 – Regulation 4 (Strength/stability); Regulation 8 (Organisation); Regulation 9 (Inspection/TE where applicable) ●PUWER 1998 – Regulation 4 (Suitability); Regulation 5 (Maintenance of accessories where applicable) ●BS 7121-1 – Accessory selection for sharp/abrasive loads; edge protection requirements; supervision intervention ●Manufacturer guidance – Sling limitations, edge protection and prohibited uses Wolf Lifting Dynamics Limited – Safety HUB | Case Study 57

Case Study 53: Forklift Used with Incorrect Chain Attachments
Incident Overview A forklift lifted rebar mesh using chains draped directly over forks without approved attachments. What Went Wrong Forks were incorrectly used as lifting points. Key Lessons Learned - Forks are not lifting points - Improvisation increases risk Safety Recommendations Forklifts must only lift loads using approved lifting attachments. ●LOLER 1998 – Regulation 4 (Stability and safe configuration); Regulation 8 (Organisation) ●PUWER 1998 – Regulation 4 (Suitability); Regulation 6 (Inspection where relevant); Regulation 9 (Training) ●BS 7121-1 – Correct selection/connection of lifting accessories; prohibition of improvised attachment methods ●Manufacturer guidance – Forklift approved lifting points/attachments only Wolf Lifting Dynamics Limited – Safety HUB | Case Study 53

Case Study 48: Double-Choke Lift with Uneven Sling Tension
Incident Overview Formwork beams were lifted using a double-choke configuration where one sling failed to tension correctly. What Went Wrong The lift continued despite visible imbalance and lack of intervention. Key Lessons Learned - Sling behaviour must be verified - Uneven tension indicates instability Safety Recommendations Lifts must stop immediately if sling behaviour is abnormal. ●LOLER 1998 – Regulation 4 (Strength and stability); Regulation 8 (Safe system of work) ●PUWER 1998 – Regulation 4 (Suitability); Regulation 9 (Training and competence) ●BS 7121-1 – Slinging techniques; requirement for test lifts and verification of load sharing ●Industry good practice – Immediate stop required where abnormal sling behaviour is observed Wolf Lifting Dynamics Limited – Safety HUB | Case Study 48

Case Study 47: Gas Bottles Lifted in a Skip Using a Net
Incident Overview Two full gas bottles were lifted inside a boat skip rather than approved bottle cages. A debris net was placed over the top to give the appearance of safety. What Went Wrong An inappropriate lifting method was used and the net provided no restraint. Key Lessons Learned - Appearance of safety is not safety - Gas bottles are high-consequence loads Safety Recommendations Gas bottles must only be lifted using approved transport cages. ●LOLER 1998 – Regulation 4 (Stability); Regulation 8 (Organisation and protection of persons) ●PUWER 1998 – Regulation 4 (Suitability of equipment for purpose) ●BS 7121-1 – Control of lifting operations; prohibition of improvised containment ●HSE Guidance (Compressed Gas Safety) – Requirement for approved gas bottle transport cages ●CDM 2015 – Management of high-consequence hazards on construction sites Wolf Lifting Dynamics Limited – Safety HUB | Case Study 47

Case Study 46: Bulk Bags Lifted Against Manufacturer Instructions
Incident Overview Multiple one-tonne bulk bags were lifted overhead on a live construction site. The bags were clearly labelled with instructions requiring a single transport lift using four chains, one connected to each corner loop. Despite this, the bags were lifted again using fewer attachment points after their initial transport lift. What Went Wrong Manufacturer instructions were ignored and no one exercised stop-work authority. Key Lessons Learned - Manufacturer instructions are mandatory - Collective silence enables unsafe lifting Safety Recommendations Bulk bags must only be lifted in accordance with manufacturer instructions. ●LOLER 1998 – Regulation 4 (Strength and stability of loads); Regulation 8 (Organisation of lifting operations) ●PUWER 1998 – Regulation 4 (Suitability of work equipment); Regulation 8 (Information and instructions) ●BS 7121-1 – Selection and use of lifting accessories; compliance with manufacturer instructions ●Manufacturer guidance – Bulk bag lifting limits, single-use lifting eyes and specified sling configurations Wolf Lifting Dynamics Limited – Safety HUB | Case Study 46
