Occupational Safety and Health Administration (OSHA) SLC Practice Exam

What is the concept of body mechanics concerned with?

1. Improper lifting techniques

2. Efficient use of the body to prevent injury

3. Health effects of physical therapy

4. Occupational safety regulations

The correct answer is: Efficient use of the body to prevent injury

The concept of body mechanics is fundamentally concerned with the efficient use of the body to prevent injury. This includes understanding the principles of movement and posture that minimize strain on muscles and joints during various tasks, particularly those that involve lifting, carrying, and pushing. Proper body mechanics aim to enhance physical efficiency and safety, allowing individuals to perform their activities effectively while reducing the risk of musculoskeletal injuries. Effective body mechanics employ techniques such as bending at the knees rather than the waist, keeping the load close to the body, and using the strength of the legs for lifting instead of relying solely on the back. By focusing on these practices, individuals can maintain good posture and alignment, which is essential for both short-term comfort and long-term health. Meanwhile, the other options touch on related but distinct concepts. For instance, while improper lifting techniques fall under the umbrella of body mechanics, they do not encapsulate the full scope of the concept. The health effects of physical therapy and occupational safety regulations are also relevant in the context of workplace safety and health but aren't the primary focus of body mechanics itself. The essence of body mechanics is centered on optimizing body movements and positions to foster safety and prevent injuries in various activities.
