🔍 Key Concepts

• USCG PFD Types and their intended use (Type I vs Type V) • How PFDs perform with unconscious persons in the water • Difference between buoyancy and comfort in work vests vs offshore life jackets

💭 Think About

• Which PFD type is normally used offshore where rescue may be delayed, and what is its main performance requirement? • What is the primary safety concern for someone who becomes unconscious while wearing a work vest? • Do work vests prioritize maximum comfort for work, or maximum ability to turn a person face up and keep them floating?

✅ Before You Answer

• Review which PFD type is designed to turn most unconscious wearers face up in the water • Confirm whether work vests are approved as life-saving devices for all situations or mainly for persons working near the water • Check if the question is testing buoyancy and face‑up performance rather than weather, comfort, or appearance
