1. Guard Against Electric Shock on Sites
Source : Frédéric BISSON
Burns, electrocution and shocks are risks associated with electricity which can result in serious
injury and death. For this reason employers need to guard against electric shock on site. Burns
are the most common type of injury and can be either electrical burns as a result of heat
generated by the flow of electric current through the body, arc or flash burns caused by an
electric arc or explosion and a thermal contact burns caused by overheated electric equipment.
Electrocution is also a major hazard and is most commonly caused by contact with overhead
powerlines, contact with energised sources and the incorrect use of extension and flexible
cords.
Employers should conduct a risk assessment to determine the risk electricity may represent.
They also need to develop a safe work method statement in order to minimise the workers risk
of burns or electrocution. Workers need to conduct themselves in a safe manner that will not
present a hazard to themselves or their co-workers.
The most effective ways of minimising electrocution hazards are:
Maintaining a safe distance from overhead powerlines
Inspecting portable tools and extension cords before use
Using power tools and equipment as designed and instructed by the manufacturer
Following correct lockout/tagging procedures
