– Do not lift or carry any object when you cannot hold it tightly, even when it is not too heavy but bulky or too large for you to hold.
– Do not lift or carry an object if it is over 20kg, asking for help or using mechanical aids.
Posture to lift a heavy load
– Hold a load at the level of your belly bottom, keep your upper back straight, bend your knees and hips. Do not lean your hips forwards, knees straight. Keep your body at the posture as required.
– Do not twist your body, use your feet to change direction, do not twist your hips because it is easy to get injured.

– Your feet should be shoulder-width apart and close to the object as possible, firm footing.
– Do not reach out/lift the object over your head, using platform or ladder to get the same height as the object.
– Observe above the object, preventing things from falling on your eyes and face.
– Keep the object as close your body as possible, keep your elbows close to your body.
