When heavy objects are being hoisted, do not walk under the cantilever or the objects.
Only trained and qualified personnel should perform hoisting operations.
Check that hoisting tools are available and in good condition.
Before hoisting objects, ensure that hoisting tools are firmly fixed onto a weight-bearing
object or wall.
Ensure that the angle formed by two hoisting cables is no more than 90 degrees, as
shown in the following figure.
1.5.2 Using Ladders
Use only ladders that are in good condition. Do not exceed the maximum weight
capacity of the ladders.
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, and that the ladder is securely positioned.
