Absolutely no objects, tools, or materials are to be carried in hands while ascending/ descending ladders.
A three point contact must be maintained with the ladder at all times.
A rope and soft tool bucket must be used for hoisting and lowering of all hand tools as required.
All hand tools must be attached to the operator by a lanyard at all times.
A tool belt must be utilized where possible.
Apart from the control measures discussed above, ensure that work areas directly below you are barricaded to prevent unauthorized access into the area.
This could be further managed through the use of spotters to warn others.
Never leave tools lying around and always return them to their proper storage place.
Never use tools at elevated positions if they are not fitted with lanyards.
