Which of the following is a Type IV device?

• A. A USCG-approved Type IV throwable device (ring buoy)
• B. A PFD
• C. A fire extinguisher
• D. A visual distress signal

Answer: (A)

Type IV devices are flotation aids that you throw to a person in the water, not something you wear. A ring buoy fits this definition perfectly: it’s lightweight and buoyant, designed to be tossed to someone who’s in distress so they can grab onto it and stay afloat. A personal flotation device (PFD) is meant to be worn for buoyancy, so it’s not a Type IV device. A fire extinguisher serves as a fire safety tool, not flotation. A visual distress signal is used to attract attention and signal for help, not to provide buoyancy. So the option describing a USCG-approved Type IV throwable device (ring buoy) is the correct one.
