Any aspect of a job that imposes a physical stressor or pain on a welder is called an 'ergonomic risk factor'.

• A. Ergonomic hazard
• B. Ergonomic risk factor
• C. MSD
• D. PPE

Answer: (B)

The main idea is identifying job conditions that increase the chance of musculoskeletal issues. A part of the work that imposes a physical stress or pain on a welder is an ergonomic risk factor because it names a specific exposure in the job that raises the likelihood of harm. It focuses on the contributor to risk, not the injury itself or the equipment used to prevent harm. The outcome, such as a musculoskeletal disorder, is what you want to avoid, not the factor causing it. PPE refers to protective gear, which helps reduce exposure but isn’t the factor itself. An ergonomic hazard is a related term describing something that can cause harm, but the phrasing here aligns best with “risk factor” since it points to a particular aspect of the job that contributes to risk.
