Use wooden or insulated ladders when you need to perform live-line working
at heights.
Platform ladders with protective rails are preferred. Single ladders are not
recommended.
Before using a ladder, check that it is intact and confirm its load bearing
capacity. Do not overload it.
Ensure that the ladder is securely positioned and held firm.
When climbing up the ladder, keep your body stable and your center of
gravity between the side rails, and do not overreach to the sides.
When a step ladder is used, ensure that the pull ropes are secured.
If a single ladder is used, the recommended angle for the ladder against the
floor is 75 degrees, as shown in the following figure. A square can be used to
measure the angle.
If a single ladder is used, ensure that the wider end of the ladder is at the
bottom, and take protective measures to prevent the ladder from sliding.
If a single ladder is used, do not climb higher than the fourth rung of the
ladder from the top.
If you use a single ladder to climb up to a platform, ensure that the ladder is
at least 1 m higher than the platform.
