🔍 Key Concepts

• Immersion suit equipment requirements in SOLAS and 46 CFR (coastwise and oceangoing vessels) • Purpose of an immersion suit in cold-water survival situations • Difference between required equipment and optional or supplementary survival gear

💭 Think About

• Think about what items are absolutely essential for being located and rescued at night while floating in the water. • Which pieces of equipment are commonly required on ALL personal lifesaving appliances, such as lifejackets and immersion suits? • Among the choices, which item(s) would be more complex to maintain or refill, and therefore less likely to be a mandatory built‑in feature of every immersion suit?

✅ Before You Answer

• Verify what minimum equipment must be attached to immersion suits under SOLAS/46 CFR, not what might be nice to have. • Check which of the listed items are also standard on lifejackets, as immersion suits follow similar signaling requirements. • Be sure the item(s) help with detection and location rather than extended underwater survival or concealment.
