Before using a ladder, ensure that it is intact and its load bearing capacity is
adequate. Do not load a ladder with a weight in excess of its duty rating.
Use wooden or fiberglass ladders when you need to perform live-line working
at heights.
Platform ladders with protective rails are preferred. The ladder must be
secured at the four feet and held by a person.
When a step ladder is used, ensure that the pull ropes are secured and the
ladder is held firm by a person.
If a straight ladder is used, the ladder must be placed in a secure place. The
recommended angle for a ladder against the floor is 75 degrees, as shown in
the following figure. An angle ruler can be used to measure the angle. Ensure
that the wider end of the ladder is at the bottom, or protective measures have
been taken at the bottom to prevent the ladder from sliding. The ladder must
be held by another person during the operation.
