QUESTIONS WITH 100% CORRECT VERIFIED ANSWERS

GRADED A (STUDY GUIDE)

A colorless, odorless, electrically nonconductive inert gas that is a suitable medium for extinguishing Class B and Class C fires Carbon Dioxide A powder composed of very small particles, usually sodium bicarbonate, potassium bicarbonate, or ammonium phosphate-based with added particulate material supplemented by special treatment toprovide resistance to packing, resistance to moisture absorption (caking), and the proper flow capabilities Dry Chemical Normally an aqueous solution of organic or inorganic salts or a combination thereof that forms an extinguishing agent. Wet chemical Electrically non-conducting, volatile, or gaseous fire extinguishant that does not leave a residue uponevaporation. Clean Agent A system that is constructed in a manner that does not introduce foreign material into the agent being recovered and has a means of visually inspecting the recovered agent for contaminants. Dry Chemical Closed Recovery System A system that provides for the transfer of halogenated agents between fire extinguishers, supply containers, and recharge and recovery containers so that none of the halogenated agent escapes to the atmosphere. Halogenated Closed Recovery System

High-Pressure Cylinder Cylinders containing fire extinguishing agent (medium), nitrogen, compressed air, or other compressed gases at a service pressure of 500 psi (3447 kPa) or lower at 70°F (21°C). Low-Pressure Cylinder Solid materials in powder or granular form designed to extinguish Class D combustible metal fires by crusting, smothering, or heat-transferring means. Dry Powder Either a local alarm device to indicate when an extinguisher is removed from its designated location or a method of electronic communication (data transmission) between an in-place fire extinguisher and an electronic monitoring device/system. Electronic Monitoring Extinguisher retention device designed to mount and secure a specific extinguisher model onto various surfaces by incorporating releasable straps or bands to secure the fire extinguisher. Extinguisher Bracket An identifiable and readily accessible fire extinguisher housing device designed to store and protect fire equipment. Extinguisher Cabinet Extinguisher mounting device designed for mounting a specific extinguisher model onto stationary vertical surfaces. Extinguisher Hanger A quick check that a fire extinguisher is in its designated place, that it has not been actuated or tampered with, and that there is no obvious physical damage or condition to prevent its operation. Extinguisher Inspection

A thorough examination of the fire extinguisher that is intended to give maximum assurance that a fire extinguisher will operate effectively and safelyand to determine if physical damage or condition will prevent its operation, if any repair or replacement is necessary, and if hydrostatic testing or internal maintenance is required. Extinguisher Maintenance A solution that will form an aqueous film on liquid fuels Film-Forming Foam 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 protein-foam solution that uses fluorinated surfactants to produce a fluid aqueous film for suppressing liquid fuel vapors. Study These Flashcards FFFP Flammable liquids at least 1/4" deep Flammable liquids of appreciable depth Pressure testing of the extinguisher to verify its strength against unwanted rupture. Hydrostatic testing A water-based extinguishing agent that uses an alkali metal salt as a freezing point depressant. Loaded stream extinguisher All steel shells other than stainless steel and steel shells used for high-pressure cylinders. Mild Steel Shell The normal operating pressure as indicated on the nameplate or cylinder of a fire extinguisher. Extinguisher Service Pressure The pressure shown on the nameplate at which a shell was tested at time of manufacture.

Factory Test Pressure Fires resulting from liquids that are forced, pumped, or sprayed. Pressurized Flammable Liquid Fires The replacement of the extinguishing agent (also includes the expellant for certain types of fire extinguishers). Recharge The actual walking distance from a point to the nearest fire extinguisher fulfilling hazard requirements. Travel Distance A concentrate that, when added to water, reduces the surface tension and increases its ability to penetrate and spread. Wetting Agent Surfactant A fire extinguisher in which the expellant gas is in a separate container from the agent storage container. Cartridge/Cylinder Operated A fire extinguisher that is intended to be used one time and not capable of or intended to be recharged and returned to service. Nonrechargable A fire extinguisher in which the agent has sufficient vapor pressure at normal operating temperatures to expel itself. Self Expelling A fire extinguisher in which both the extinguishing agent and expellant gas are kept in a single container, and that includes a pressure indicator or gauge. Stored Pressure

A fire extinguisher containing distilled or de-ionized water and employing a nozzle that discharges the agent in a fine spray. Water Mist A fire extinguisher containing water-based agents, such as water, film-forming foam agents (AFFF, FFFP), antifreeze, loaded stream, and wet chemical.
