If a heavy object is pulled from far away to save time, what is the correct ergonomic decision?

Answer and explanation

Correct answer: Keep the object near and at safe height

The direct answer is B: move the heavy object near the worker and place it at a safe height. Ergonomics seeks safe efficiency, not speed at the cost of injury. Step by step, pulling a heavy object from far away makes the arms reach, increases bending and creates greater force on the back and shoulders. Bringing it close shortens the reach; a safe height reduces deep bending or overhead lifting; together these reduce strain. A is wrong because continuing the unsafe method preserves the risk. C is wrong because less light makes visibility and safety worse. D is wrong because removing breaks increases fatigue and injury risk. Saving a few seconds is not worthwhile if it causes harm. Exam cue: first reduce distance, excessive reach and awkward height; then consider speed.
