Identify common ergonomic risks in welding and practical strategies to mitigate them.

• A. Repetitive motions, awkward postures, heavy lifting; use adjustable stations, rests, mechanical aids, break schedules, and job rotation
• B. Loud noises, toxic fumes, oil spills
• C. Unclear PPE, lack of training
• D. Visual distractions and long shifts

Answer: (A)

The main idea here is identifying ergonomic risks in welding and how to reduce the physical strain they cause. Repetitive motions, awkward postures, and heavy lifting are classic sources of musculoskeletal stress for welders. The option that names these risks and pairs them with practical, in-workplace fixes is the strongest because it directly targets how the body is loaded during welding.

Adjustable stations help welders work with neutral, less cramped postures; rests and micro-breaks cut the time muscles spend under load, reducing fatigue and stiffness; mechanical aids such as hoists, trolleys, clamps, and positioners lessen the effort and awkward reaching required to move and hold parts; scheduled breaks and job rotation spread out repetitive work and give tissues time to recover. Together, these measures change the task environment and workflow to minimize strain and injury.

The other choices address different safety concerns—environmental hazards like noise and fumes, broader safety-program gaps like unclear PPE or training, or fatigue factors that aren’t specifically about ergonomic load. While those are important, they don’t target the core ergonomic risks and their direct remedies the way the chosen approach does.
