Which of the following is NOT a principle of manual handling?

Manual handling principles are essential for ensuring safety and efficiency when lifting, carrying, or moving objects. The concept of operation deadline does not pertain to manual handling techniques or safety considerations. Rather, it refers to time constraints related to tasks or project completion, which do not influence the physical techniques or strategies used to minimize the risk of injury during manual handling.

In contrast, the principles of ergonomics, load management, and mechanical advantage are critical components of manual handling. Ergonomics focuses on designing tasks to fit the worker's capabilities and reduce strain. Load management involves assessing the weight, size, and shape of the object being handled to determine safe lifting techniques. Mechanical advantage emphasizes the use of equipment or body mechanics to reduce the effort needed to lift or move loads safely. These principles collectively help in preventing injuries and promoting a safer workplace environment.
