Lifting Devices
All lifting devices and material hoists should be regularly inspected.
They should meet BSEE and U.S. Coast Guard requirements and be labeled for maximum lifting capacity. Be sure to follow these rules when hoisting:
Onboard signaller with reflective arm band.
- Lifting devices should be operated only by competent/qualified, authorized workers.
- One worker should be designated as a signaller (flagger).
- Lifting device operators should take direction from the signaller.
- Anyone can give the all-stop signal.
- The operator should determine the weight of the object to be lifted prior to performing a lift.
- Cables, lifting devices, slings, and wire ropes should be inspected immediately prior to use to make sure they are in proper condition, and positioned to support the weight of the load.
- Examine the boom angle to make sure it is appropriate for the load and the expected dynamics of the load.
- Develop form lift plans whenever critical lifts, such as heavy lifts, lifts over process equipment, or lifts involving two cranes, are required.
- Perform a JSA for lifts where the operator cannot see the load.
- Make sure that a signalman is properly positioned to signal the lift when the operator cannot see the load.
- No person should be positioned such that any part of the body is under the load being lifted by a crane, side boom, or other lifting device.
- Unbalanced loads or lift materials should never be lifted directly above workers.
- Never use lifting devices to pull loads sideways.
