3.1

personal flotation device

PFD

garment or device which, when correctly worn and used in water, provides the user with a specific amount of buoyancy which increases the likelihood of survival

3.2

inherently buoyant

permanently less dense than water

3.3

automatic inflation

inflation of the PFD (3.1) without the user carrying out any action at the time of water immersion

3.4

manual inflation

inflation of the PFD (3.1) resulting from the user operating a mechanism

3.5

oral inflation

inflation resulting from the user blowing air into the PFD (3.1) by mouth

3.6

emergency position-indicating light

device which emits light so as to increase the chances of a user being located

3.7

multi-chamber buoyancy system

PFD (3.1) with buoyancy to meet the applicable PFD performance requirement provided by two or more independent chambers

Note 1 to entry: This excludes supplemental inflation chambers.

3.8

deck safety harness

device that allows a user to be securely attached to a strong point on a vessel or on shore, preventing a fall into the water or, if falling occurs, preventing separation from the vessel or shore

3.9

buddy line

length of cord which can be tied or otherwise fixed to another person or to that person's PFD (3.1) or other objects, so as to keep a user in the vicinity of that person or object with a view to making location and thus rescue easier

3.10

lifting loop

device which facilitates manual recovery of a person from water

3.11

sprayhood

cover brought or placed in front of the airways of a user in order to reduce or eliminate the splashing of water from waves or the like onto the airways, and thereby promoting the survival of the user in rough water conditions

3.12

protective cover

cover that is normally in place over the functional elements of a PFD (3.1) in order to protect them from physical damage, or snagging on external objects

Note 1 to entry: The protective cover may be designed to provide additional properties, i.e. to make the PFDs suitable for use when the subject is exposed to additional hazards, e.g. significant abrasion, molten metal splash, flame and fire.

Note 2 to entry: The inflatable chamber of an inflatable PFD is an example of a functional element.

3.13

overpressure relief valve

valve which may be used in an inflatable system to avoid the likelihood of destruction caused by overpressure

3.14

whistle

device which, when blown by mouth, produces an audible sound which can aid in the location of the user

3.15

hybrid PFD

PFD (3.1) of combined buoyancy types, i.e. inherent and inflatable

3.16

bunching

curling or folding of internal buoyant material upon itself, from its original position, within the envelope

3.17

sheltered waters

water with protection from significant breaking waves, current, or strong winds, where the possibility of being blown or carried away from shore or a place of safety is minimal

3.18

offshore

water that is unprotected and influenced by a variety threat conditions such as waves, tide, currents, or wind, at sea or on inland waters

3.19

primary means of inflation

means of inflating an inflation chamber that meets the applicable PFD performance requirements and that requires the least amount of intervention by the user, generally according to the following order of precedence: automatic (easiest), manual (second), and oral (most difficult)

3.20

secondary means of inflation

alternate method of inflation which is provided in case the primary means of inflation (3.19) fails

3.21

primary chamber

inflation chamber associated with the primary means of inflation (3.19) that alone meets the applicable PFD (3.1) performance requirements

3.22

back-up chamber

inflation chamber other than the primary chamber(s) (3.21) or supplemental chamber (3.23) that, when used alone, provides performance in case the primary chamber fails to function

3.23

supplemental chamber

inflation chamber other than a primary chamber (3.21) or back-up chamber (3.22) that is intended for deployment after stabilization in the water, and provides enhanced performance such as higher freeboard, improved head support, additional stability, splash protection, location, detection

3.24

status indicator

part or parts of an inflation system which provide user feedback to assist in keeping an inflatable PFD in an armed and ready condition

3.25

adult lifejacket

PFD (3.1) intended for users with a body mass greater than 40 kg

3.26

infant lifejacket

lifejacket intended for users with a body mass less than or equal to 15 kg

3.27

child lifejacket

lifejacket intended for users with a body mass greater than 15 kg and less than or equal to 40 kg

3.28

structural parts, materials and components

parts, materials, or components that are integral to the device and that are essential for its correct function and performance

3.29

ride-up prevention system

system that helps to secure the PFD (3.1) in its functional position on the body and prevents the PFD from riding up the body towards the head

Note 1 to entry: A crotch strap is one example of a ride-up prevention system.

3.30

collar handle

device on the upper back of a PFD (3.1) which facilitates getting hold of the wearer

3.31

personal locator device

PLD

device that aids the (electronic) detection and location of people in distress and emergency situations
