You are watching: Eq-25 which of the following is a feature of a type iv pfd

kind I – naturally buoyant recommended uses and also features:

Intended Use:When cruising, racing and also fishing offshore , or once boating alone, or in stormy conditions.

Advantages: an extremely comfortable, more buoyant than kind II inherently Buoyant jackets.

Disadvantages: High price; may be hand-operated or automatic.

There are many form V (special use) blow up jackets (covered later in this section) the provide type II performance characteristics.

Inflatable PFDs are not meant for kids under the age of 16.

type III – inherently buoyant encourage uses and features:

Intended Use:Supervised activities, such as sailing regattas, dinghy races, water skiing, fishing, canoeing, kayaking and during an individual watercraft operation.

Not suitable for expanded survival in turbulent water. Not designed to revolve unconscious people face increase in water.

More comfortable come wear 보다 a type I or a type II, but provides far less floatation 보다 a type I.

form III – blow up recommended uses and also features:

Intended Use:For boating inshore and also near shore and for supervised tasks such as sailing regattas, dinghy races, canoeing.

Minimum Buoyancy:22.5 lbs. Because that adult size.

Additional Information:Not guaranteed to revolve unconscious wearer face-up.

Advantages: more comfortable than a type III inherently Buoyant jacket.

Disadvantages: one manual inflation system only.

Inflatable PFDs room not expected for youngsters under the period of 16.

type IV – Throwable Device:

Intended Use:A form IV is draft to be thrown come an overboard victim or to complement the buoyancy of a human overboard. It is not to it is in worn. Minimum buoyancy: 16.5 lbs. For ring buoy or 18 lbs. For watercraft cushion.

Minimum Buoyancy:15.5 come 22 lbs. For adult size.

Additional Information:Must be worn when underway to satisfy minimum US shore Guard requirements. Simply having a form V PFD top top board will certainly not satisfy the USCG carriage requirements.

type V – automatic inflation models:

Intended Use:Restricted come the one usage for which that is designed, ex. Belt pack, deck suit, rise coat.

Minimum Buoyancy:22.5 come 34 lbs. Relying on style.

Additional Information:Must be worn to accomplish federal requirements.

Not guarantee to revolve an unconscious wearer face-up. Some manufacturers claim kind II performance. Part models function a combination of CO2 inflation and also built-in foam and provide 15.5 to 22 lbs. Of buoyancy.

form V – Hybrid Inflation and also some distinct notes:

Intended Use:Models recommended for boating tasks where rescue is surrounding and need to be worn once underway.

Minimum Buoyancy:Have 7.5 lbs. Of built-in foam buoyancy and can be inflated to 22 lbs.
