How must a safety harness be worn while operating a boom lift?

A safety harness must be properly fitted and securely attached while operating a boom lift to ensure the highest level of protection for the operator. This correct positioning of the harness is essential in preventing falls, which can lead to serious injuries or fatalities when working at height.

When worn correctly, the safety harness distributes the forces of a fall across the body, thereby reducing the risk of injury during an unexpected fall. The harness should fit snugly against the body without being overly restrictive, allowing for freedom of movement while still providing the necessary security. Additionally, it should be attached to a suitable anchor point on the lift structure or boom, ensuring that it functions effectively if needed.

In contrast, options suggesting a loose or partially fitted harness undermine safety protocols and increase the risk of injury. Similarly, only wearing a harness when working over a certain height does not account for scenarios where falls could occur at lower elevations, making it important to use the harness at all times when operating a boom lift, regardless of the working height.
