True or False: Wearing a Type I or III PFD over an anti-exposure coverall may be dangerous in certain situations.

Wearing a Type I or III personal flotation device (PFD) over an anti-exposure coverall can indeed be dangerous in certain situations due to the potential for restricted movement and the risk of buoyancy affecting the wearer’s ability to maneuver. Type I and III PFDs are designed for wear in various situations, but when combined with anti-exposure coveralls, they can alter how an individual moves, which may impede effective action in emergencies.

For instance, anti-exposure coveralls are intended to provide thermal protection and buoyancy, but they can also create challenges in navigating through water or performing physical tasks. If a wearer were to fall into the water while wearing both a PFD and coveralls, the buoyancy and fit of these layers might hinder their ability to swim or escape from dangerous circumstances. This is particularly significant in scenarios where agility and quick reaction times are essential.

Situations like rescue operations or stormy conditions could amplify these risks. However, the core issue is the combination of the two types of gear and the potential for restricted mobility, making it crucial to assess the environment and activity type when deciding what gear to wear. Thus, the answer being true reflects the nuanced understanding of safety while wearing layer upon layer of protective equipment.
