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. |
