Mechanical Safety

General Requirements

• Repaint any paint scratches caused during equipment transportation or installation in a timely manner. Equipment with scratches cannot be exposed for an extended period of time.
• Do not perform operations such as arc welding and cutting on the equipment without evaluation by the Company.
• Do not install other devices on the top of the equipment without evaluation by the Company.
• When performing operations over the top of the equipment, take measures to protect the equipment against damage.
• Use correct tools and operate them in the correct way.

Moving Heavy Objects

• Be cautious to prevent injury when moving heavy objects.

• 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.

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 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.

• If a single ladder is used, ensure that the wider end of the ladder is at the bottom, and take protective measures to prevent the ladder from sliding.
• If a single ladder is used, do not climb higher than the fourth rung of the ladder from the top.
• If you use a single ladder to climb up to a platform, ensure that the ladder is at least 1 m higher than the platform.

Hoisting

• Only trained and qualified personnel are allowed to perform hoisting operations.
• Install temporary warning signs or fences to isolate the hoisting area.
• Ensure that the foundation where hoisting is performed on meets the load-bearing requirements.
• Before hoisting objects, ensure that hoisting tools are firmly secured onto a fixed object or wall that meets the load-bearing requirements.
• During hoisting, do not stand or walk under the crane or the hoisted objects.
• Do not drag steel ropes and hoisting tools or bump the hoisted objects against hard objects during hoisting.
• Ensure that the angle between two hoisting ropes is no more than 90 degrees, as shown in the following figure.

Drilling Holes

• Obtain consent from the customer and contractor before drilling holes.
• Wear protective equipment such as safety goggles and protective gloves when drilling holes.
• To avoid short circuits or other risks, do not drill holes into buried pipes or cables.
• When drilling holes, protect the equipment from shavings. After drilling, clean up any shavings.
