Question text not reproduced: the examination questions are © Engineers and Geoscientists BC. Open the official past paper (linked at the top of this page) to read the question, then follow the worked solution below.

(i) Controlling Hand-Tool Hazards

• Right tool for the job; inspect/maintain (sharp, sound handles; remove defective tools); ergonomic design (neutral wrist, insulated handles for electrical work); safe-use practices (cut away from body, secure workpieces); guards; safe carry/storage; PPE and training.

(ii) Factors in Manual-Handling Injuries / Low-Back Pain

• Load (heavy, bulky, unstable, poor grip); posture/technique (bending, twisting, reaching, floor/overhead lifts); task (repetition, duration, frequency, carry distance); force (push/pull, jerking); environment (restricted space, poor footing/lighting); individual (capacity, fatigue, prior injury, training).

(iii) Recommended Lifting Procedures

• Size up the load; get help/aid if needed; stand close, feet apart; bend the knees, keep the back straight; firm grip; lift smoothly with the legs, load close; do not twist (turn the feet); keep the load between knuckle and shoulder height; set down with the legs.
