In which situation will only personal training not be enough for an ergonomic solution?

Correct answer: When heavy items are always stored above head level

The direct answer is B: heavy objects are always stored above head level. Training can teach a worker a safer lifting method, but it cannot by itself remove a dangerous storage design. A heavy item above the head may require reaching, stretching, awkward posture, and lifting from an unstable position; it can also fall onto the worker. The solution should include redesigning the storage area, moving heavy items to waist-to-chest height, and then reinforcing safe handling through training. Option A may often be improved mainly by teaching the correct lifting method, so training could address it, although equipment and load assessment may also matter. Option B is correct because the physical arrangement itself must change. Option C is wrong because being new does not automatically create an ergonomic hazard; orientation may help. Option D is wrong because simple work can still be designed safely and does not explain the specific danger. Memory cue: training changes behaviour; redesign changes the hazard.
