Safe Operating Procedures, Load Handling and Communication Signals
Safe operation rests on a few non-negotiables: never carry people on a materials hoist; never exceed the rated capacity; keep the load secured and within the platform; keep gates closed and interlocked; maintain constant-pressure control so movement stops when the control is released; and never leave a loaded platform unattended or a control station unattended with the hoist live.
Load handling: centre and distribute the load, keep it below the top of the platform or gate height, secure loose items against wind and movement, and check that nothing overhangs where it could strike the structure, landings or ropes. Do not drag loads onto the platform. At the landing, the loading person must stand clear of the edge and never reach across a moving platform.
Communication is critical where the operator cannot see the load or the landing. Agree signals before the lift: hand signals, whistle, radio or a combination, with one designated signaller and one recognised stop signal that overrides all others. Radio users need a clear channel and a checked battery. If communication is lost, stop and secure.
Traps: multiple people giving signals; treating the stop signal as advisory; and assuming the operator can see the landing when the platform is above eye level.
Rule of thumb: one signaller, one set of signals, one stop signal - and anyone may give the stop.
