Which safety practice should an occupational health nurse teach factory workers to prevent back injuries?

Holding the object close to the body while lifting is a critical safety practice that significantly reduces the risk of back injuries. When objects are kept close to the body, the center of gravity is more stable, which helps maintain balance and reduces the strain on the back muscles and spine. This technique utilizes the strength of the legs rather than the back to lift, promoting a safer lifting posture.

In contrast, lifting with the back straight, while important, does not fully prevent injury if the object is not held close to the body. Twisting the body while lifting can increase the risk of injury, as this motion places additional stress on the spine and can lead to muscle strain. Lifting heavy objects quickly is also discouraged because it can lead to improper form and increases the likelihood of overexertion and injury. Therefore, teaching workers to hold objects close to their bodies when lifting is an essential practice to minimize the risk of back injuries in an occupational setting.
