Note: The Coast Guard is working with the PFD community to revise the classification and labeling of PFDs. When completed, this information will be updated and hopefully be somewhat easier to understand. Meanwhile, spending a few minutes to understand the many options available to find a PFD that you’re willing to wear could mean the difference between life and death for you or a loved one.

Each PFD sold for use on a recreational boat is required to be provided with a guide to selection entitled “Think Safe – Choose the Right PFD”. These pamphlets are tailored to the kind of PFD to which they are attached. The following information is a combination of information taken from the various pamphlets and additional guidance.

PFD INFORMATION ON WEARING AND CARING

BUOYANCY: Most adults only need an extra seven to twelve pounds of buoyancy to keep their heads above water. A PFD can give that "extra lift," and it's made to keep you floating until help comes. But a PFD is a personal flotation device and it's important to get the right one for you.

Your weight isn't the only factor in finding out how much "extra lift" you need in water. Body fat, lung size, clothing, and whether the water is rough or calm, all play a part.

Read the label on your PFD to be sure it's made for people your weight and size. Test it as shown in the next section. Then in an emergency, don't panic. Relax, put your head back and let your PFD help you come out on top.

V - Special Use Device - Buoyant Foam	15.5 to 22.0 (70 to 100)

TRY YOUR PFD:

Try on your PFD to see if it fits comfortably snug. Then test it in shallow water to see how it handles.
To check the buoyancy of your PFD in the water, relax your body and let your head tilt back. Make sure your PFD keeps your chin above water and you can breathe easily.
Be aware: your PFD may not act the same in swift or rough water as in calm water. The clothes you wear and the items in your pockets may also change the way your PFD works.
If your mouth is not well above the water, get a new PFD or one with more buoyancy.
A PFD is designed not to ride-up on the body when in the water. But, when a wearer's stomach is larger than the chest, ride-up may occur. Before use, test this PFD in the water to establish that excessive ride-up does not impair PFD performance.

WEAR YOUR PFD:

Most drownings occur way out at sea, right? Wrong! Fact is, 9 out of 10 drownings occur in inland waters, most within a few feet of safety. Most of the victims owned PFDs, but they died without them. A wearable PFD can save your life, if you wear it.
If you haven't been wearing your PFD because of the way it makes you look or feel, there's good news. Today's PFDs fit better, look better and are easy to move around in.
One more thing. Before you shove off, make sure all on board are wearing PFDs. To work best, PFDs must be worn with all straps, zippers, and ties fastened. Tuck in any loose strap ends to avoid getting hung-up.
When you don't wear your PFD, the odds are against you. You're taking a chance on your life.

CARING FOR YOUR PFD:

Follow these points to be sure your PFD stays in good condition:

1. Don't alter your PFD. If yours doesn't fit, get one that does. Play it safe. An altered PFD may not save your life.
2. Don't put heavy objects on your PFD or use it for a kneeling pad or boat fender. PFDs lose buoyancy when crushed.
3. Let your PFD drip dry thoroughly before putting it away. Always stow it in a well-ventilated place.
4. Don't leave your PFD on board for long periods when the boat is not in use.
5. Never dry your PFD on a radiator, heater, or any other direct heat source.
6. Put your name on your PFD if you're the only wearer.
7. Practice throwing your Type IV PFD. Cushions throw best underhand.

CHECKING YOUR PFD:

Your PFD is required to be in serviceable condition in order to be used on your boat as one of the required PFDs.
Check your PFD often for rips, tears, and holes, and to see that seams, fabric straps, and hardware are okay. There should be no signs of waterlogging, mildew odor, or shrinkage of the buoyant materials.
If your PFD uses bags of kapok (a naturally buoyant material), gently squeeze the bag to check for air leaks. If it leaks, it should be thrown away. When kapok gets wet, it can get stiff or waterlogged and can lose some of its buoyancy.
Don't forget to test each PFD at the start of each season. Remember, the law says your PFDs must be in good shape before you use your boat. Ones that are not in good shape should be cut up and thrown away.

COLD WATER SURVIVAL

The Cold Facts:

Be aware that cold water (less than 70 degrees F (21 Degrees C)) can lower your body temperature. This is called hypothermia. If your body temperature goes too low, you may pass out and then drown. Even if you're wearing a PFD, your body can cool down 25 times faster in cold water than in air.
Water temperature, body size, amount of body fat, and movement in the water all play a part in cold water survival. Small people cool faster than large people. Children cool faster than adults.
But PFDs can still help you stay alive longer in cold water. They let you float without using energy and they protect part of your body from cold water. A snug-fitting PFD is better than one that's loose-f itting. When you boat in cold water, use a flotation coat or deck-suit style PFD. In cold water, they're better than vests because they cover more of your body.
When you're in cold water, don't swim unless you can reach a nearby boat, fellow survivor, or floating object. Even good swimmers drown while swimming in cold water. Swimming lowers your body temperature.
If a nearby floating object is large, pull yourself up on it. The more your body is out of water, the warmer you'll be. Don't use drownproofing methods that call for putting your face in the water. Keep your head out of the water to lessen heat loss and increase survival time.
Use of the HELP position will lessen heat loss. However, if you're wearing a Type III PFD, or if the HELP position turns you face down, bring your legs together tight and your arms tight to your sides and your head back. See the SURVIVAL POSITION examples shown below.
If there are others in the water, HUDDLE together for warmth. Keep a positive outlook. It will improve your chances of survival.
Always wear your PFD. Even if you become helpless from hypothermia, your PFD will keep you afloat.

How hypothermia affects most adults:

Water Temperature in Degrees F (Degrees C)	Exhaustion or Unconsciousness	Expected Time of Survival
32.5 (0.3)	Under 15 min.	Under 15 to 45 min.
32.5 to 40 (0.3 to 4.5)	15 to 30 min.	30 to 90 min.
40 to 50 (4.5 to 10)	30 to 60 min.	1 to 3 hrs.
50 to 60 (10 to 15.5)	1 to 2 hrs.	1 to 6 hrs.
60 to 70 (15.5 to 21)	2 to 7 hrs.	2 to 40 hrs.
70 to 80 (21 to 26.5)	2 to 12 hrs.	3 hrs. to indefinite
Over 80 (Over 26.5)	Indefinite	Indefinite

CHILDREN & PFD SELECTION

Teach Your Children Well

Teach your children to properly wear a PFD.

Children panic when they fall into the water suddenly. This causes them to move their arms and legs violently, making it hard to float safely in a PFD. A PFD will keep a child afloat, but may not keep a struggling child face-up. That's why it's so important to teach children how to put on a PFD and to help them get used to wearing one in the water.

To work right, a PFD must fit snugly on a child. To check for a good fit, pick the child up by the shoulders of the PFD. If the PFD fits right, the child's chin and ears will not slip through.
PFDs are not babysitters. Even though a child wears a PFD when on or near the water, an adult should always be there, too. Parents should remember that inflatable toys and rafts should not be used in place of PFDs.

IMPORTANT MESSAGE - Since infants and children come in many sizes and shapes, the U.S. Coast Guard and personal flotation device (PFD) manufacturers urge that PFDs be tested immediately after purchase. You should test your PFD in a swimming pool. Test it with the infant or child who will be wearing the PFD. Just because it works for one infant or child does not mean it will work for another in the same manner. Check for proper weight range, comfortable fit, and especially a stable face-up position in water. Infants and children are difficult to float in a face-up position because of the distribution of body weight and the tendency for them to struggle or attempt to climb out of the water. Some infants and children float best in one style of vest, while others will float better in another. If one does not work well, try another style. Remember: Never leave an infant or child unattended on a dock, on a boat or in-the-water, even if they have a PFD on."

The manufacturers of child and infant PFD can be found currently listed online in our CGMIX equipment list at:

http://cgmix.uscg.mil/Equipment/EquipmentSearch.aspx

Use the keyword "infant" or "child".

Many can be found in stores that carry a good line of boating accessories. There are also a number of online sources where a Type II infant PFD can be purchased.

PFDs FOR INFANTs

The following are related questions that have been asked pertaining to baby seat type PFDs for infants:

Questions: What do you recommend for a 7 month old child? She rides in the car seat while in the car but it seems like that would sink like a rock if the boat ever capsized. What should she sit in and what type of life vest would you recommend that she wear?

USCG response: We recommend a Type II infant PFD for a child of this size.

Question: What are the recommendations/requirements for seating of infants in a recreational craft?

USCG response: If an infant is onboard a recreational boat, there must be an infant Type II personal flotation device (PFD) available for that individual. We recommend that the infant wear the PFD at all time while onboard the boat. There are no USCG requirements, nor does the USCG have a policy regarding infant seating on recreational boats.

Question: Are there break away infant seats available?

USCG response: There are no USCG approved infant seats currently approved, and there are no such devices being tested to meet our PFD requirements. We are not aware of any such device being sold.

Question: Does the USCG endorse any infant seats?

USCG response: At this time we do not, because none have been submitted for testing. If a manufacturer designs one and submits it for testing, we will consider it for USCG approval. Recently, there has been interest from inventors who may develop such a device, but to date, none have been fully tested and submitted for approval.

Question: What PFD does the Coast Guard recommend for infants.

USCG response: The Coast Guard does not recommend taking infants onboard a recreational boat. The PFDs currently available for newborns up to 18 pounds may not provide a proper fit to perform as expected. Unless the parent is able to test their newborns out in a PFD, sized for infants, in a swimming pool, they will not know if that device will float their child with his/her head out of the water. You must be sure you know the PFD you have works for your infant. Otherwise we recommend the child not be exposed to any risk in a boat on the water.

PFDs FOR PEOPLE WITH LARGER THAN NORMAL CHEST SIZES

How can someone with a chest size larger than 130 cm (52 in) get a PFD that fits?

What should a person do who exceeds the normal size range to have a personal flotation device (PFD) that fits? At some point for very large (or small) people, the individual must take responsibility for his personal equipment, because there are not enough people in the size range to make the expense of testing and approval practical for manufacturers.

Because most recreational boating accidents happen so suddenly, it is important to find a PFD that you are willing to wear whenever on open decks. But, in open water, the more comfortable PFDs will not provide for extended survival. Therefore, for off-shore sailing, fishing, etc., we suggest that carrying two PFDs be considered. A Type II or III should be worn under most circumstances and a Type I carried to be donned then the weather turns bad or for the actual abandon ship situation. A Type V hybrid inflatable PFD could serve both purposes, but 52 inch chest size is the largest approved to date.

Some manufacturers have designed Type II and III PFDs for larger chest sizes. Wearing a Type II and III together can significantly increase your chances of survival in rough water. You should test any combination you plan to use in calm water beforehand.

Adult universal size PFDs are required to fit a range of chest sizes of at least 75 - 130 cm (30 - 52 inches). Manufacturers are shown in these lists for Type I devices made with kapok flotation material and foam flotation material. Type I kapok devices are all vest style designs and most of the foam devices are yoke/bib style.

The kapok vest style design should fit chest sizes up to 137 cm (54 inches) without much difficulty. We estimate that a foam vest design will also fit most people of this size.

Yoke/bib style PFD If none of these devices is large enough for you, you exceed the top 4th percentile of the population and individual measures must be taken to provide a PFD that will fit. Clip-on body strap extensions are the preferred method of accommodating large people. We suggest that an additional length of body strap be added to a yoke/bib style PFD, such as the type pictured at the right. The same types of materials should be used as in the approved PFD. The PFD manufacturer may be willing to provide the clip-on body strap extension or necessary material. The user should then test the modified PFD in the water.

Modifying a PFD, such as (permanently) adding additional body strap webbing, voids the device's approval, no matter who does the modification. However, for a person with a chest size over 130 cm (52 inches), using an adult universal PFD with a clip-on body strap extension does not void the approval. If a PFD manufacturer wishes to provide the body strap extension, we recommend that it be provided with a PFD pamphlet and a caution that the PFD with the extension be tested by the individual user.

A PFD manufacturer (or anyone for that matter) may produce an un-approved device for larger persons without Coast Guard approval. We advise that any such device be tested in the water as mentioned above. If this option is chosen, an approved PFD must still be carried on board the boat.

DEFINITIONS

Buoyancy - The tendancy of a body to float or sink in water or any other fluid. Most people will naturally float in water, especially if they fill their lungs with air. Most require only about 11 pounds (50 Newtons) of extra buoyancy to keep their head out of water. That is why a PFD with just 15.5 pounds (70 Newtons) of buoyancy can provide adequate flotation for an adult -- even a very large person. PFDs with 22 to 34 pounds (100 to 155 Newtons) can provide superior performance.

In technical terms, buoyancy is determined by Archimedes' Principle:
Any body partially or completely submerged in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the body.

That means someone immersed in water is "buoyed" upward by a force equal to the weight of the volume of water that their body takes up (displaces). Gravity pulls a person's body downward by a force equal to their weight. The difference between these forces is a person's net buoyancy. A PFD is very light weight, but displaces enough water to make the PFD and the person wearing it very buoyant.

It also follows that the people hardest to float are those with compact, dense bodies. These tend to be people with athletic body builds, with a lot of bone and muscle mass, and not much fat. Fat is not as dense as muscle and bone, so people who are overweight can actually be easier to float than someone who is much smaller and leaner. Heavy people do not need a higher buoyancy PFD because of their weight.

Hypothermia - A lowering of body temperature, which can endanger survival. Water transfers heat away from the human body 25 times faster than air, so even moderate water temperatures can be dangerous in a relatively short time.

Inflatable - A device which depends on flexible air chambers which can be filled with air or other gas (usually carbon dioxide) for flotation.

Inherently Buoyant - A device which relies on buoyant material for flotation. Buoyant materials used in Personal Flotation Devices include -
Kapok - A natural silky fiber produced from the seed of the kapok (ceiba) tree which floats because of air trapped in the fibers' hollow cells.
Plastic Foams - Materials consisting of closed plastic cells which trap air and provide flotation. Flexible plastic foams used for buoyancy include Polyvinyl Chloride (PVC), Polyethylene (PE), and Neoprene. Rigid foams used in ring lifebuoys are often polyurethane.

Newton - The metric (SI) system measure of force. A one pound force equals about 4.4 Newtons.

Serviceable condition - A PFD is considered to be in serviceable condition only if the following conditions are met:

1. No PFD may exhibit deterioration that could diminish the performance of the PFD including:

Metal or plastic hardware used to secure the PFD on the wearer that is broken, deformed, or weakened by corrosion;
Webbings or straps used to secure the PFD on the wearer that are ripped, torn, or which have become separated from an attachment point on the PFD; or
Any other rotted or deteriorated structural component that fails when tugged.

2. In addition to meeting the requirements of paragraph (a) of this section, no inherently buoyant PFD, including the inherently buoyant components of a hybrid inflatable PFD, may exhibit:

Rips, tears, or open seams in fabric or coatings that are large enough to allow the loss of buoyant material;
Buoyant material that has become hardened, non-resilient, permanently compressed, waterlogged, oil-soaked, or which shows evidence of fungus or mildew; or loss of buoyant material or buoyant material that is not securely held in position.

3. In addition to meeting the requirements of paragraph (a) of this section, an inflatable PFD, including the inflatable components of a hybrid inflatable PFD, must be equipped with:

Except as provided in paragraph (d) of this section, a properly armed inflation mechanism, complete with a full inflation medium cartridge and all status indicators showing that the inflation mechanism is properly armed;
Inflatable chambers that are all capable of holding air;
Oral inflation tubes that are not blocked, detached, or broken;
A manual inflation lanyard or lever that is not inaccessible, broken, or missing; and
Inflator status indicators that are not broken or otherwise non-functional.

4. The inflation system of an inflatable PFD need not be armed when the PFD is worn inflated and otherwise meets the requirements of paragraphs (a) and (c) of this section.
