5. When lifting heavy objects, you should: [1 mark) a) Keep your arms extended so the object is away from your body at all times
b) Keep one hand free at all times.
c) Keep your back slightly bent at all times
d) Make sure that your leg muscles, not your back muscles, do the lifting

Hope this helps

Explanation:

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.
