Accidents and deaths can occur when equipment becomes 'live' due to electrical faults, lack of maintenance, or short circuits. Doing maintenance work on live electrical circuits is another common cause of electrocution.
Electrical accidents are usually caused by a combination of factors such as: •
lack of training or supervision
•
unsafe work practices
•
equipment not properly installed, maintained, tested and tagged
•
a hazardous work environment, where electrical hazards may not be recognised.
Electrocution often occurs when people misjudge heights and distances between the ground and overhead wires when carrying equipment like poles and ladders, or operating equipment with height extension such as cranes. Remember, 'Look Up and Live'.
General safety precautions •
Apprentices, trainees and work experience students must be supervised at all times by a qualified worker,
and must never attempt to carry out any work that could expose them to an electrical hazard. •
Only licensed electrical workers can legally do electrical work. An unqualified person must not be asked to
do electrical work. •
Keep powered tools and equipment in safe working order through inspection and preventative maintenance
programs. •
