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.
Only trained and qualified personnel are allowed to perform hoisting
operations.
Install temporary warning signs or fences to isolate the hoisting area.
Ensure that the foundation where hoisting is performed meets the load-
bearing requirements.
Before hoisting objects, ensure that hoisting tools are firmly secured onto a
fixed object or wall that meets the load-bearing requirements.
During hoisting, do not stand or walk under the crane or the hoisted objects.
Do not drag steel ropes and hoisting tools or bump hoisted objects against
hard objects during hoisting.
