Do not pile up scaffolding, springboards, or other sundries on the ground
under the area involving working at heights. Do not allow people to stay or
pass under the area involving working at heights.
Carry operation machines and tools properly to prevent equipment damage or
personal injury caused by falling objects.
Personnel involving working at heights are not allowed to throw objects from
the height to the ground, or vice versa. Objects should be transported by
slings, hanging baskets, highline trolleys, or cranes.
Do not perform operations on the upper and lower layers at the same time. If
unavoidable, install a dedicated protective shelter between the upper and
lower layers or take other protective measures. Do not pile up tools or
materials on the upper layer.
Dismantle the scaffolding from top down after finishing the job. Do not
dismantle the upper and lower layers at the same time. When removing a

Use wooden or insulated ladders when you need to perform live-line working

Platform ladders with protective rails are preferred. Single ladders are not
recommended.
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 and held firm.
When climbing up the ladder, keep your body stable and your center of
gravity between the side rails, and do not overreach to the sides.
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.
