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.
Obtain consent from the customer and contractor before drilling holes.
Wear protective equipment such as safety goggles and protective gloves when
drilling holes.
To avoid short circuits or other risks, do not drill holes into buried pipes or
cables.
When drilling holes, protect the equipment from shavings. After drilling, clean
up any shavings.
