Electrical safety improvements are a common issue we identify at many sites and workplaces. Many of these issues are minor to remediate, but could be catastrophic if left unattended.

Electrical hazards aren’t always highly visible, so electrical safety tends to be

viewed as something for electricians or technical experts to worry about. For most

workers electrical dangers are simply not on their radar.

Remember there is no device that can offer you 100% protection from electrocution.

It is important that you remember to keep safe.

Electrical Injuries

There are two ways that electricity hazards can cause harm.

• Electric Shock - electrical current passing through your body.

Electric shock can cause severe burns and potentially dangerous involuntary

movements. An electric shock can be fatal if it passes through vital organs.

• Arc Flash - release of energy.

Arc Flash can result in blast injuries, lung injuries, ruptured eardrums, shrapnel

wounds, severe burns and blindness. Arc Flash can be fatal.

Common Electrical Safety Failures

During site inspections we often see these common electrical safety failures.

In your next site inspection keep these in mind and identify any electrical

improvements that could be made at your workplace.

• Tangled electrical cords. Ensure cords are organised and a cord to an

electrical source is easily identifiable.

• Overloaded or “Piggy backing” of power boards or extension leads.

• Non-commercial power boards or extension cords.

• Cords causing trip issues in pathways.

• Rubbish, dust, paper based materials or liquids stored near to electrical

outlets or electrical equipment.

• Damaged equipment or cords used.

• Tools and electrical equipment being left on when not in use.

• Using electrical equipment near water or having the cord in water.

• Using equipment close to overhead power lines.

• Incorrect equipment for the job

General Lifesaving Tips for Working Near Electricity

When working with or near electricity it is important to consider all electrical

wires and equipment are live until they are tested and proven otherwise.

Some other important tips to consider are:

• Turn off the switch before unplugging leads

• Display safety signage and / or update hazard board when electrical work is

being carried out.

• Inspect cords, plugs and electrical equipment before each use. Lock Out,

repair or replace any damage equipment immediately.

• Secure extension cords or power boards to the wall or floor where possible.

• Use extension cords or equipment that are rated for your type of work

(commercial grade).

• Avoid exposed wiring.

• Warm or Hot outlets can be a sign of unsafe wiring conditions.

• Use ladders made with non conductive material (fiberglass)

• Locate electrical panels and circuit breakers in case of an emergency.

Ensure pathways are clear and accessible.

• Use Lock Out equipment as required.

• Use equipment with Residual Current Device (RCD) when using heavy duty

equipment.

• Keep electrical equipment away from water, liquids and any other materials

that could become ignited.

Tag & Test

It is best practice for electrical appliances, tools and

leads to undergo regular testing or “test and tag”. The

frequency of testing a device is determined by where it is used:

• New appliance - before first use

• Building site - every 3 months

• Factories - every 6 months

• Office Equipment - either yearly or up to five years

in some situations (seek electricians advice)

• Refer to AS/NZS3760:2010

Even when items have been tested and tagged before using, best practice recommends

• Using the inbuilt testing button to manually test RCDs before use

• Checking all electrical appliance tools prior to use

• Where faults are detected, apply “Out of Order” / Lockout tags until repaired by a Registered Electrician
