Which action is specifically listed as a common cause for crew member injuries related to twisting?

• A. Overreaching to grab a pencil.
• B. Walking during a shift.
• C. Improper twisting.
• D. Proper lifting with leg muscles.

Answer: (C)

Twisting injuries happen when the torso rotates while you’re lifting, reaching, or carrying something, especially if you twist rather than reorient your whole body. The direct risk here is improper twisting, because it describes the exact motion that puts rotational stress on the spine and back muscles. When you twist under load without using proper form—keeping your hips and feet aligned with the direction you’re moving and letting your legs do the work—the stress on the spine can lead to strains or other injuries over time. The other actions aren’t about twisting as the injurious motion: overreaching to grab a pencil can cause shoulder or back strain but doesn’t specify twisting; walking is just movement; and lifting with the legs is a safe technique that reduces injury risk, not a cause.
