Answer:

1. When lifting a load from ground level, bend knees, keep back straight, keep load close to your body, lift with leg muscles, support forearms with knees, and support the load with your body. When lowering a load, use leg muscles and lower the load by bending your knees, not your back.

2.Factors that need to be considered are sizes of cargo being loaded or unloaded, the method used to load or unload (i.e. crane, forklift, etc.), movement of cargo, what can go wrong, and where people need to be if something does go wrong.

3.Do not attempt to lift by bending forward. Bend your hips and knees to squat down to your load, keep it close to your body, and straighten your legs to lift. Never lift a heavy object above shoulder level. Avoid turning or twisting your body while lifting or holding a heavy object.
