What determines the necessity of providing PFDs on-site?

The necessity of providing Personal Flotation Devices (PFDs) on-site is primarily determined by the risk of drowning. When assessing whether PFDs are required, it is crucial to evaluate the potential hazards present in the work environment, such as bodies of water that workers may be exposed to. The USACE EM 385-1-1 guidelines emphasize safety measures based on identified risks, particularly in situations where workers might be at risk of falling into water or where water hazards could lead to drowning.

Even in locations where other factors—like the type of machinery or the number of workers—are considered, the ultimate determinant focuses on safety concerning potential drowning incidents. Therefore, PFD requirements are mandated in environments where such risks are present, ensuring that workers have the necessary protection to enhance their safety while performing tasks near water. This approach prioritizes worker safety and helps to prevent accidents that could lead to severe consequences.
