Which PFD types are mentioned as potentially dangerous when worn over anti-exposure coveralls?

• A. Type I only
• B. Type II only
• C. Type I or III
• D. Type III only

Answer: (C)

The main idea is how outer clothing can affect how a PFD sits and works. When you wear anti-exposure coveralls, the extra bulk can change the way a PFD contacts your body, how it inflates, and how it stays in place in the water. Type I offshore PFDs are the bulkiest and designed to turn an unconscious wearer face-up; over bulky coveralls they can ride up or shift, reducing effective buoyancy distribution and face-up protection. Type III PFDs are vest-style and rely on a close fit to stay properly positioned; over thick outerwear they can also ride up or move out of alignment, compromising performance. These factors make those two types potentially dangerous in this setup.
