1.5.1 Hoisting

Issue 02 (2019-08-30)
When working at heights, comply with local relevant laws and regulations.
Only trained and qualified personnel are allowed to work at heights.
Before working at heights, check the climbing tools and safety gears such as safety
helmets, safety belts, ladders, springboards, scaffolding, and lifting equipment. If they do
not meet the requirements, take corrective measures or disallow working at heights.
Wear personal protective equipment such as the safety helmet and safety belt or waist rope
and fasten it to a solid structure. Do not mount it on an insecure moveable object or metal
object with sharp edges. Make sure that the hooks will not slide off.
Set a forbidden area and eye-catching signs for working at heights to warn away irrelevant
personnel.
Carry the operation machinery and tools properly to prevent them from falling off and
causing injuries.
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 tough 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 properties on the upper layer.
Ensure that guard rails and warning signs are set at the edges and openings of the area
involving working at heights to prevent falls.
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.
Inspect the scaffolding, springboards, and workbenches used for working at heights in
advance to ensure that their structures are solid and not overloaded.
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.
Before climbing up a ladder, ensure that the ladder is secure and free of cracks The angle
between the ladder and the ground should be 75° . When a step ladder is used, ensure that
the pull ropes are secured and the ladder is held firm.
Do not loiter when working at heights. Do not sleep at heights.
Any violations must be promptly pointed out by the site manager or safety supervisor and
the involved personnel should be prompted for correction. Personnel who fail to stop
violations may be forbidden from working and the suspension is considered as
absenteeism.
Operators who violate the safety regulations are responsible for accidents caused. The
supervisor has to bear the responsibility accordingly.
