All cranes and derricks must be inspected, tested, and maintained in safe operating condition. Equipment must have a load capacity visible on the boom and hook block. All defects discovered during inspection must be corrected before the equipment is used again. Only qualified operators with current credentials may operate cranes. Operators must receive training on the specific equipment they will operate and must demonstrate competency before being assigned. A signal person must be stationed where they can see the operator and the load, and must use standard hand signals to direct crane operations. Clear communication between the operator and signal person is essential for safe lifts. Rigging must be performed by qualified riggers who have been trained on load calculation, equipment selection, and proper hitching techniques. Load paths must be planned to avoid personnel and structures. No personnel are allowed to stand under suspended loads. Barricades must keep all personnel away from potential drop zones. Hooks and slings must be inspected before each use and must meet strength requirements for the load. Dynamic and side pull forces must not exceed the rated capacity. Cranes must not be moved while loaded unless the boom is in the lowered position. Weather conditions that create hazards must stop crane operations. Daily pre-operation inspections must verify all functions are operating properly.
