Using Ladders
● 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
conrm its load bearing
capacity. Do not overload it.
● Ensure that the ladder is securely positioned and held rm.
● 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
oor is 75 degrees, as shown in the following gure. 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.
