Fire Extinguishers Flashcards
An extinguishing agent used in dry-chemical fire extinguishers that can be used on Class A, B and C fires.
Ammonium Phosphate
A solution based on fluorinated surfactants plus foam stabilizers to produce a fluid aqueous film for suppressing liquid fuel vapors.
Aqueous film-forming foam (AFFF)
A colorless, odorless, electrically nonconductive inert gas that is a suitable medium for extinguishing Class B and Class C fires.
Carbon Dioxide
A fire extinguisher in which the expellant gas is in a separate container from the agent storage container
Cartridge/cylinder-operated fire extinguisher
A fire in ordinary combustible materials, such as wood, cloth, paper, rubber, and many plastics.
Class A Fire
A fire in flammable liquids, combustible liquids, petroleum greases, tars, oils, oil-based paints, solvents, lacquers, alcohols, and flammable gases.
Class B Fire
A fire that involves energized electrical equipment
Class C Fire
A fire in combustible metals, such as a magnesium, titanium, zirconium, sodium, lithium, and potassium.
Class D Fire
A fire in a cooking appliance that involves combustible cooking media (vegetable or animal oils and fats)
Class K Fire
Electrically nonconducting, volatile, or gaseous fire extinguishant that does not leave a residue upon evaporation.
Clean agent
The body of the fire extinguisher where the extinguishing agent is stores.
Cylinder
A powder composed of very small particles, usually sodium bicarbonate, potassium bicarbonate, or ammonium phosphate based with added particulate material supplemented by special treatment to provide resistance to packing, resistance to moisture absorption, and the proper flow capabilities.
Dry Chemical
Solid materials in powder or granular form designed to extinguish Class D combustible metal fires by crusting, smothering, or heat-transferring means.
Dry Powder
A material used to stop the combustion process. May include liquids, gases, dry-chemical compounds, and dry-powder compounds.
