Working at heights refers to operations that are performed at least 2 meters above the
ground.
Do not work at heights if the steel pipes are wet or other potential danger exists. After the
preceding conditions no longer exist, the safety director and relevant technical personnel
need to check the involved equipment. Operators can begin working only after obtaining
consent.
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 restricted 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.
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.
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 will be forbidden from working.
Do not walk under hoisted 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 secured onto a load-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.
