Signalling is an important part of hoisting and rigging. You should be familiar with the internationally recognized system of standard hand signals.
If you’re going to rig a load, you also need to know the signals for lifting, moving and landing it. The operation may be a simple LIFT and LOWER, or it may require more complicated signals.
In many cases, hand signals are the most efficient form of communication between riggers and crane operators.
On construction sites, signalling is required in five situations:
Hand signals have their limitations. For example, they should never be used when distance or visibility prevents accurate communication with the operator.
There is a signal for each action of the crane. By using the correct hand signals you can get a crane to do almost anything you want. The operator only needs to clearly see and understand your signals.
These are the ground rules for signalling:
[See Safety Talk #18, for demonstration of the hand signals for hoisting.]
In New Brunswick, the main provisions on hoisting apparatus and mobile cranes can be found in General Regulation 91-191 under the Occupational Health and Safety Act, sections 207 – 215.
