Safe Operation, Environmental Hazards and Emergency Procedures
This domain combines day-to-day operating discipline with weather and emergency response.
Operating discipline
- Follow the lift plan; know the load weight and the radius before slewing.
- Never exceed the chart; use slow, controlled motions; avoid shock loading and side pulls.
- Keep people out of the slewing and landing zones; never lift over unprotected persons.
- Maintain clearance from overhead lines per the applicable safe distance; treat lines as live.
Environmental hazards
- Wind: monitor at the crane; stop when the manufacturer's limit is reached; remember wind on the load increases effective area and can exceed the load chart assumptions.
- Lightning and storms: follow the manufacturer's procedure; leave the crane in the out-of-service configuration.
- Ice, snow, poor visibility, heat all affect operations and ground conditions.
Emergency procedures
- Power failure: know how to lower the load safely using the manufacturer's emergency lowering procedure.
- Brake or control failure: stop, secure the area, follow the emergency plan.
- Fire, collision, structural damage: stop work, evacuate the exclusion zone, report.
Traps
- Treating the in-service wind limit as a target rather than a maximum.
- Forgetting that an out-of-service configuration is a specific, manufacturer-defined state.
Rule of thumb
When conditions exceed the limits or control is uncertain, the safe action is to stop, secure, and report.
