Manual Handling and Material Storage
You are a roof cladding team leader. Your team needs to move 6 m long steel sheets weighing 25 kg each from the delivery truck to the roof. The roof is 10 m high. There is no crane on site. The team consists of four workers, one of whom has a history of back problems. The site is muddy and uneven. The sheets are stacked on the ground in a way that requires twisting to lift. The weather is cold and wet.
1. What manual handling risks are present and how should they be managed?
Read the worked answer
Risks: lifting heavy, long sheets (25 kg each, 6 m long) can cause back injury, especially with twisting, uneven ground, and cold/wet conditions. One worker has a history of back problems, so individual capability must be considered. Controls: 1) Avoid manual handling if possible: use mechanical aids such as a crane, telehandler, or vacuum lifter. 2) If manual handling is necessary, conduct a manual handling risk assessment (MAC tool). 3) Reduce weight: order shorter sheets or use two people per sheet. 4) Improve ground conditions: create a firm, level path. 5) Provide training in safe lifting techniques. 6) Ensure the worker with back problems does not perform heavy lifting; assign them other tasks. 7) Use PPE: gloves with good grip. 8) Warm-up and breaks in cold weather. 9) Team lifting: coordinate lifts with clear commands.
2. How should the sheets be stored and moved to the roof?
Read the worked answer
Sheets should be stored on a firm, level surface, preferably on bearers to keep them off the ground and prevent damage. They should be stacked so they don't fall, and secured against wind. To move to the roof, use a crane or telehandler with a suitable lifting attachment (e.g., spreader beam) to avoid damaging the sheets. If no crane, use a hoist or a material lift. Never carry sheets up ladders. Plan the lift: ensure the lifting equipment is suitable, the operator is competent, and the load is secure. Use tag lines to control the load. Keep people clear of the lifting area. If manual handling to the roof is unavoidable, use a safe system of work with adequate personnel and rests.
