Do not drag steel ropes and hoisting tools or bump hoisted objects against hard objects
during hoisting.
Using Ladders
Use wooden or fiberglass ladders when you need to perform live working at heights.
When a step ladder is used, ensure that the pull ropes are secured and the ladder is held
firm.
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. The recommended angle for a ladder
against the floor is 75 degrees, as shown in the following figure. An angle rule 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.
When climbing a ladder, take the following precautions to reduce risks and ensure
safety:
Keep your body steady.
Do not climb higher than the fourth rung of the ladder from the top.
Ensure that your body's center of gravity does not shift outside the legs of the ladder.
