Which statement is true regarding proper body mechanics in the workplace?

Good body mechanics play a crucial role in preventing injuries, particularly in a workplace that involves physical activity. When an individual employs proper techniques while lifting, moving, or performing tasks, it significantly lowers the risk of strain and overexertion, which can lead to musculoskeletal injuries. This includes maintaining a stable base of support, bending at the knees rather than the waist, and keeping the load close to the body.

The assertion about good body mechanics preventing injuries aligns with principles of ergonomics and safety in various environments, especially in settings involving manual labor or repetitive tasks where physical strain is common. Understanding and applying these principles can lead to a healthier workplace and improved efficiency.

The other statements do not hold true in the same context. For example, proper mechanics are not only necessary when handling heavy items; they are important for all types of movements to ensure safety and reduce injury risk. Additionally, healthy posture can indeed be maintained over long periods through proper training and ergonomic practices. Lastly, while using equipment can aid in reducing the physical load on the body, it does not completely eliminate the need for proper body mechanics, as improper use of equipment can still lead to injury.
