Which statement best reflects the safety concern with wearing PFDs over anti-exposure coveralls?

• A. Type I PFDs over anti-exposure coveralls are safe in all conditions
• B. Type II PFDs over anti-exposure coveralls are dangerous only in cold weather
• C. Type I or III PFDs over anti-exposure coveralls may be dangerous in certain situations
• D. PFDs should never be worn with anti-exposure coveralls

Answer: (C)

Wearing a PFD over anti-exposure coveralls can change how the flotation device sits and works, because the bulky garment can prevent a snug, correct fit. If the PFD doesn’t sit tightly against the body, its buoyancy isn’t distributed as designed, and it may shift, ride up, or fail to position you properly in the water. That matters for types I and III, because each relies on a specific fit to perform its job. Type I provides the most buoyancy and is designed to turn a person face-up in rough conditions, but this relies on a secure fit against the torso. If an anti-exposure suit underneath causes the PFD to ride up or gap at the neck or sides, it may not turn you as intended or keep your head oriented correctly. Type III is designed for mobility and comfort, but it also depends on being worn snugly; over bulky coveralls, it can shift, reducing effective buoyancy and potentially compromising upright orientation or rapid response in an emergency. So the safest takeaway is that these PFDs over anti-exposure coveralls may be dangerous in certain situations, rather than being universally safe or strictly prohibited in all conditions.
