For safety sake, when working with an extension ladder outside a client’s building, be sure to know the surroundings well enough to maintain a safe distance from attached high-voltage wires. If you expect to be working near live electrical wires, you should select a ladder with nonconductive side rails. This will prevent current flow and electrocution if contact should occur. In this regard it may be wise to use a wooden or fiberglass ladder.
The surface on which you place your extension ladder also should be dry and not slippery. The area around the base of the ladder and directly underneath it should also be clear of debris. You should also refrain from using platforms, trucks, or other surfaces as a support for the bottom of a ladder as these can promote slippage.
OSHA also recommends that you don’t walk away from your ladder for extended periods. When left unattended, children and others can climb on them and suffer a fall, or they may inadvertently pull the ladder over. Not only can this cause damage to your client’s facility, but it can also result in injury or death, especially if it should come in contact with high-voltage wires on the outside of a building.
OSHA also suggests that you ” ... maintain at least three points of contact with the ladders you (two feet and one hand, or two hands and one foot) should be in contact with the ladder at all times.” In addition, no more than one person should be on an extension ladder at a time.
