An ergonomic risk factor is any aspect of a job that imposes a physical stressor or pain on a welder.

• A. True
• B. False
• C. Sometimes
• D. Not related to welding

Answer: (A)

Ergonomic risk factors are aspects of a job that place physical stress on the welder and can lead to pain or injury. In welding, overhead work, awkward postures, repetitive motions, heavy or forceful tool use, and vibration all create these stresses. Because these factors can cause discomfort or musculoskeletal issues, the statement is true. Some tasks may involve less risk or none at all, but the definition itself is about any job aspect that imposes physical stress, which fits the statement. The other options don’t align with how we define ergonomic risk factors.
