Signs are shown in the correct style with descriptive text as required by - The Health and Safety (Safety Signs and Signals) Regulations 1996.
These regulations encourage all member states of the European Union to use standard safety signs and signals, so that safety signs, wherever they are used, have the same meaning. There are four types:
Banksmans signals
Using banksmen to control reversing operations can put the Banksman in the potential danger area of a reversing vehicle. Every year banksmen suffer serious and fatal injuries whilst at work. If you do use banksmen, make sure they are trained to carry out their duties safely.
There must be a safe system of work that ensures the Banksman and driver are using standard signals, so that they are easily understood, and that the driver knows to stop the vehicle immediately if the Banksman disappears from view.
The standard signals are given in the Health and Safety (Signs and Signals) Regulations 1996 L64[1], available from HSE Books.
