Why should you not use metal ladders around electrical wire or machinery?

When should you not use a metal ladder?

8. Don’t Use Metal Ladders Near Electrical Equipment or Power Lines. Aluminum or other metal ladders should be avoided if working around electrical wires, power lines, or other electrical hazards. In this application, wood or fiberglass ladders may be your best bet.

Why should you never use Aluminium ladders for electrical work?

The obvious thing to start with is that metal ladders (such as aluminium and similar materials) should never be used when dealing with electricity, because of their conductive nature. … These consist of overhead, uninsulated power cables supported on wooden poles or insulators on metal structures.

Where should metal ladders not be used?

Metal ladders should never be used for electrical work or near uninsulated electrical conductors.

Why metal ladders should not be used near power lines?

Electrocutions can occur when: Consumers move ladders that accidentally touch an overhead electrical wire near the house or street. Metal ladders and wood ladders with metal reinforcement wire can conduct electricity, which can shock or kill anyone touching the ladder or touching someone in contact with the ladder.

Is an aluminum ladder safe?

Choosing the Right Ladder

Ladders are made of one of three materials: wood, aluminum, or fiberglass. Aluminum ladders are dangerous around electricity because they conduct electricity, although it is the least likely to break down over years of use.

What is the OSHA standard for ladders?

The minimum clear distance between side rails for all portable ladders must be 11.5 inches (29 cm). edge of a landing area must be no less than 7 inches (18 cm) and no more than 12 inches (30 cm). A landing platform must be provided if the step-across distance exceeds 12 inches (30 cm).

Are fiberglass or aluminum ladders better?

Fiberglass tends to be much stronger than aluminum. This doesn’t mean aluminum ladders are not strong. … An aluminum ladder is fairly resistant to weather, but a fiberglass ladder is even more resistant. In addition, fiberglass ladders are resistant to electricity, which means they are safer around power lines.

Can an aluminum ladder conduct electricity?

Aluminum ladders are less expensive than fiberglass ones and lighter than the wooden models. Their main drawback is that they conduct electricity and can be dangerous to use around electrical wires.

Is aluminum conductive to electricity?

Aluminum. Aluminum is yet another metal known for its high conductivity of electricity. Though by volume its conductivity is only 60% of copper, by weight, one pound of aluminum has the electrical current-carrying capacity of two pounds of copper. … Aluminum is often used in satellite dishes.

Can you get shocked on an aluminum ladder?

In the OSHA and NIOSH statistics I am privy to, 17 of those 300 people were electrocuted on, or working near, aluminum ladders. … Aluminum ladders don’t develop spider-cracks, shatter or fracture from rough use like fiberglass can, and don’t rot like wood.
