3-MPROGRAM
Program that requires the testing of
damage control equipment and preparation of
inspection reports. These actions improve the
reliability of systems and equipment through
documentation of maintenance information for
analysis.
ABSORPTION
Penetration of solid materials or
liquids by a foreign substance (such as a chemical
agent) without a chemical reaction.
ACCESSMAN
The accessman will open doors,
hatches, and clear routes as necessary to provide
access to the fire when directed by the scene leader.
ACTIVE DESMOKING
Removing smoke and heat
from the smoke control zone between the inner
smoke boundary and outer smoke boundary before
extinguishing the fire, aiding fire-fighting efforts,
and reducing smoke spread in the ship. Active
desmoking is applied only for fires that involve
primarily class ALPHA and class CHARLIE
materials.
ACUTE EXPOSURE
Those in which doses are
received in a short time, normally less than 24
hours, as a result of exposure to initial radiation,
base surge, or fallout, or combinations thereof.
ACUTE RADIATION DOSE
A dose of ionizing
radiation that is received over a period of time that is
too short for biological recovery to occur.
ADSORPTION
Adhesion of molecules of a foreign
substance (such as a chemical agent) to the surface
of solid materials (including crevices) or liquids
without a chemical reaction.
AEROSOL
A suspension of fine liquid droplets or
solid particles in a gaseous medium, the particles
being small enough to remain suspended for a
significant period of time and behave like a vapor;
examples of solid particulate aerosols are dust and
smoke; common liquid droplet aerosols are
perfumes, oil mists, and fog.
AEROSOLIZATION
The physical process of
breaking up solid or liquid into small particles or
droplets and suspending them in air.
AFFF SINGLE-SPEED INJECTION PUMP
Permanently mounted, positive displacement,
electrically driven, sliding-vane type of pump.
AFFF SPRINKLER SYSTEM
An AFFF sprinkler
system is a subsystem of AFFF generating systems.
AFFF STATION OPERATOR
The AFFF station
operator ensures that there is a constant supply of
AFFF to the hose team for fire fighting.
AFFF TANKS
The tanks are rectangular or
cylindrical in shape and are fabricated out of 90/10
copper-nickel or corrosion-resistant steel. Each
service tank is located inside the AFFF station and
is fitted with a gooseneck vent, drain connection,
fill connection, liquid level indicator, recirculating
line, and an access manhole for tank maintenance.
AFFF TRANSFER PUMPS
Permanently mounted,
single-speed, centrifugal type, electrically driven
pump. These pumps are provided in 360 gpm
capacity. The transfer pump moves AFFF
concentrate through the AFFF fill-and-transfer
subsystem to all AFFF station service tanks on a
selective basis
AFFF TRANSFER SYSTEM
The transfer system
can deliver AFFF concentrate to on-station service
tanks via a transfer main. The transfer main consists
of a large pipe with smaller branch connections
interconnecting the AFFF service and storage
tanks
AFFF TWO-SPEED INJECTION PUMP
Designed to meet the demand for either a low or a
high fire-fighting capability. The two-speed AFFF
pump consists of a positive displacement pump
rated at 175 psi, a motor, and a reducer, coupled
together with flexible couplings and mounted on a
steel base.
AFLOAT TRAINING GROUPS (ATG)
Provide
Navy ships with examples and packages of
recommended damage control drills.
AFTER WELL DECK
Between the upper deck and
the poop deck.
AIR BLAST
The shock wave that is produced in the
air by an explosion. The shockwave initially travels
outward at a velocity of approximately seven times
the speed of sound at high overpressures. It will then
gradually slow down to a sonic speed of about
1,000 fps at low overpressures.
AIR BLAST INJURY
Personnel can be picked up
and thrown by the blast. They receive their injuries
upon landing. The extent of the injuries will depend
upon the velocity of the body’s movement, the
nature of the object with which the body collides,
and the nature of impact, whether glancing or solid.
AIRBURST
A burst where the point of detonation is
below an altitude of 100,000 feet, and the fireball
does not touch the surface of the earth. Air blast,
thermal radiation (heat and light), electromagnetic
pulse, and initial nuclear radiation (neutron and
gamma rays) are produced around the point of
detonation
AIR CHANGE
The process of introducing a volume
of air into a compartment that is equal to the volume
of the compartment while simultaneously removing
an equal volume. Because of mixing, only 65
percent of the air originally in the compartment is
removed in one air change
AIR CONTAMINANT
A substance or material that
is foreign to the normal composition of the
atmosphere, usually occurring in the form of
aerosols, dusts, fumes, mists, gases, and vapors.
AIR LOCK
A shipboard passageway with a
quick-acting watertight (QAWT) door on either
end. Only one door is opened at a time to prevent the
flow of air from a pressurized part of the ship to an
unpressurized area. Air locks are also equipped
with fittings to allow purging of contaminated air.
ALPHA (A) FIRES
Those that occur in such
ordinary combustible materials as wood, cloth,
paper, upholstery, and similar materials.
ALPHA PARTICLE
A form of ionizing nuclear
radiation consisting of positively charged
subatomic particles emitted by some radioactive
materials. An alpha particle is identical to the
nucleus of a helium atom in mass, structure, and
electrical charge but an alpha particle’s energy level
is higher due to its speed.
ANTIFLASH CLOTHING
Intended to protect
personnel from transient high temperatures that
may occur from the use of high explosive weapons
and from being burned in a fire. Antiflash clothing
consists of an antiflash hood and antiflash gloves.
APPROVED (FOR THE PURPOSE)
Equipment
or materials that have been tested, evaluated, and
determined to be acceptable by a recognized testing
laboratory or inspection agency according to the
requirements of a particular code or specification
for a particular purpose, environment, or
application.
AQUEOUS FILM-FORMING FOAM FIRE
EXTINGUISHER (AFFF
Used to provide a
vapor seal over a small fuel spill, to extinguish small
class BRAVO fires (such as deep-fat fryers), and for
standing fire watch during hot work.
AQUEOUS FILM-FORMING FOAM (AFFF)
AFFF, also known as “light water,” is a synthetic,
film-forming foam designed for use in shipboard
fire-fighting systems.
