● If multiple persons need to move a heavy object together, determine the
manpower and work division with consideration of height and other
conditions to ensure that the weight is equally distributed.
● If two persons or more move a heavy object together, ensure that the object
is lifted and landed simultaneously and moved at a uniform pace under the
supervision of one person.
● Wear personal protective gears such as protective gloves and shoes when
manually moving the equipment.
● To move an object by hand, approach to the object, squat down, and then lift
the object gently and stably by the force of the legs instead of your back. Do
not lift it suddenly or turn your body around.
● Do not quickly lift a heavy object above your waist. Place the object on a
workbench that is half-waist high or any other appropriate place, adjust the
positions of your palms, and then lift it.
● Move a heavy object stably with balanced force at an even and low speed. Put
down the object stably and slowly to prevent any collision or drop from
scratching the surface of the equipment or damaging the components and
cables.
● When moving a heavy object, be aware of the workbench, slope, staircase,
and slippery places. When moving a heavy object through a door, ensure that
the door is wide enough to move the object and avoid bumping or injury.
● When transferring a heavy object, move your feet instead of turning your
waist around. When lifting and transferring a heavy object, ensure that your
feet point to the target direction of movement.
● When transporting the equipment using a pallet truck or forklift, ensure that
the tynes are properly positioned so that the equipment does not topple.
Before moving the equipment, secure it to the pallet truck or forklift using
ropes. When moving the equipment, assign dedicated personnel to take care
of it.
● Choose sea or roads in good conditions for transportation as transportation
by railway or air is not supported. Avoid tilt or jolt during transportation.
Working at Heights
● Any operations performed 2 meters or higher above the ground should be
supervised properly.
● Only trained and qualied personnel are allowed to work at heights.
● Do not work at heights when steel pipes are wet or other risky situations
exist. After the preceding conditions no longer exist, the safety owner and
relevant technical personnel need to check the involved equipment. Operators
can begin working only after safety is conrmed.
● Set a restricted area and prominent signs for working at heights to warn away
irrelevant personnel.
● Set guard rails and warning signs at the edges and openings of the area
involving working at heights to prevent falls.
● Do not pile up scaolding, springboards, or other objects 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 scaolding from top down after nishing 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.
● Ensure that personnel working at heights strictly comply with the safety
regulations. The Company is not responsible for any accident caused by
violation of the safety regulations on working at heights.
● Behave cautiously when working at heights. Do not rest at heights.
Using Ladders
● Use wooden or insulated ladders when you need to perform live-line working
at heights.
● Platform ladders with protective rails are preferred. Single ladders are not
recommended.
● Before using a ladder, check that it is intact and conrm its load bearing
capacity. Do not overload it.
● Ensure that the ladder is securely positioned and held rm.
● 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
oor is 75 degrees, as shown in the following gure. A square can be used to
measure the angle.
