Any operations performed 2 meters or higher above the ground should be
supervised properly.
Only trained and qualified personnel are allowed to work at heights.
Do not work at heights when steel pipes are wet or other risky situations

relevant technical personnel need to check the involved equipment. Operators
can begin working only after safety is confirmed.
Set a restricted area and prominent signs for working at heights to warn
irrelevant personnel away.
Set guard rails and warning signs at the edges and openings of the area

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
part, ensure that other parts will not collapse.
