What is the potential hazard of a poorly fitted full body harness?

A poorly fitted full body harness poses a significant risk because it can lead to injury due to improper support. Specifically, if the harness does not fit the user's body correctly, it might not distribute the forces exerted during a fall adequately. This improper distribution can result in concentrated pressure on certain parts of the body, causing discomfort, bruising, or even serious injuries such as suspension trauma, where the body is subjected to gravity and lacks proper support after a fall.

Proper fitting is essential for ensuring that a full body harness functions as intended. When correctly fitted, the harness should support the user securely, preventing excessive movement and keeping them positioned safely during work activities. In contrast, a poorly fitted harness may shift during movement, increasing the likelihood of injury and reducing the overall effectiveness of the fall protection system.

While dizziness, fall risk, and restricted movement can also be concerns associated with harness use, the most critical issue concerning safety and injury prevention stems from the inadequate support it provides when the harness is not fitted properly.
