Difficulty: Moderately Easy
Step1
Read and follow all safety warnings and instructions on the ladder and only use ladders for their designed purposes.
Step2
Ascertain the ladder’s maximum load rating and do not exceed it. Don't forget to consider the weight of any tools or equipment being used on the ladder.
Step3
Look for and avoid overhead power lines and other energized electrical equipment before handling a ladder. Avoid using a metal ladder near electrical hazards.
Step4
Inspect the ladder prior to using it. If the ladder is damaged, it must be removed from service and tagged until repaired or discarded.
Step5
Use a ladder only on a stable and level surface, unless it has been secured (tied or braced) at the top or bottom to prevent displacement. If a ladder is to be used in an area where it can be displaced by other activities, then it should also be secured or a barrier should be erected to ensure the ladder is not disturbed.
Step6
Open step ladders to their fully opened position and be sure they are locked in that position. Never use a step ladder as a single ladder or in a partially open position. When using an extension ladder, ensure that the locks holding the extension in place are fully engaged.
Step7
An extention ladder should extend at least 3 feet above the point of support at the top of the ladder. In other words, if the ladder is being used to climb onto a roof then the ladder should extent at least 3 feet above the roof edge where the ladder is being supported. Also, the ladder should be set up with its base a quarter of the working length of the ladder from the wall or other vertical surface. For example, it the roof is 12 feet above the ground, then the base of the ladder should be 3 feet from the base of the wall.
Step8
Maintain a 3-point (two hands and a foot, or two feet and a hand) contact on the ladder when climbing. Keep your body near the middle of the step and always face the ladder while climbing.
