Extension Lead SAFETY TIPS

Extension leads are a common accessory to keep around the house or have on a job site.
They are pretty much used everyday across every industry.

There are a few points for concern which we need to mention.
Our team has highlighted key points that may keep you, your family or team a little safer when utilising these accessories.

  1. Never overload an extension lead with power, as they are manufactured to only handle a certain amount.
    Overloading an extension lead can quickly become hazardous and cause fires
  2. Based on the length and thickness of the extension lead determines how much current it is able to insulate. The more this is manipulated the greater the risk becomes. It is important to always follow the guidelines that comes with each lead and never plug an extension lead into another to increase the range of power, as this influences the leads insulation capability.
    Without knowing it, you could be putting yourself and the people around you at risk to an electric shock.
  3. Always fully untangle/wind an extension lead prior to use as this can prevent coils and knots in the lead from overheating
  4. When removing a lead from a wall socket, always pull from the plug and never from the lead (this repetitive tension will lead to wire damage and an increase in the risk associated with a damaged lead)
  5. Always be aware of any damage to a lead, such as a burning smell, blackness around the plug, sparks when in use and frayed or exposed wires from within the insulation
  6. If a lead is plugged in and begins to spark this is an IMMEDIATE call for concern. A lead should never produce power until a full circuit is connected, such as a power tool being plugged in.
    If this is occurring its an obvious sign that the lead is damaged and something is causing a short.
    Our best recommendation is to discard this lead immediately.
  7. It is important to note the longer the extension lead, generally the less current it is able to contain.
    Ensure if using equipment that draws a lot of power, it should be compensated with a heavy duty lead that can withstand a stronger current.

These are just some points we believe could prevent injury or harm in the future.
We cant stress this enough to always show caution around electricity and never be naive to its hazards.

The environment in which a lead is exposed too can drastically effect its condition.
If a lead is sitting in 40 degree heat all day, running tools, being stepped on and coming into contact with cement/nails.
It wont be long before a hazard arises.

If you own an extension lead or use them on a construction site daily we highly recommend to book an inspection every 6 months due to the nature of construction work and the environment they are exposed to while on site.
