(AHJ) - ANSWERAuthority Having Jurisdiction
O rganization, office or individual responsible for enforcing requirements of a code
or standard, or for approving equipment, materials, an installation or procedure.
Shall - ANSWERIndicates a mandatory requirement.
Should - ANSWERIndicates a recommendation or that which is advised but not
required.
Dry Chemical - ANSWERA 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 (caking), and the proper flow capabilities
Wet Chemical - ANSWERNormally an aqueous solution of organic or inorganic salts
or a combination thereof that forms an extinguishing agent
Clean agent - ANSWERElectrically nonconducting, volatile, or gaseous fire
extinguishant that does not leave a residue upon evaporation
Dry Chemical Closed Recovery System - ANSWERA system that does not introduce
foreign material into the agent being recovered and has a means of visually
inspecting the recovered agent for contaminants
Halogenated Closed Recovery System - ANSWERA system that provides for the
transfer of halogenated agents between fire extinguishers, supply containers, and
recharge/recovery containers so that none of the halogenated agent escapes to the
atmosphere.
(ODP) - ANSWEROzone Depletion Potential

_______*F - ANSWER500 PSI at 70*F
Dry Powder - ANSWERSolid materials in powder or granular form designed to
extinguish Class D combustible metal fires by crusting, smothering, or heat-
transferring means
Film-forming foam agents - ANSWERAqueous film-forming foam (AFFF) and film-
forming fluoroprotein foam (FFFP).
HFC - ANSWERHydrofluorocarbon
HCFC - ANSWERHydrochlorofluorocarbon
Halocarbons - ANSWERInclude HCFC HFC PFC and FIC types of agents and other
types of halocarbons that are found acceptable under the Environmental Protection
Agency Significant New Alternatives policy program
FIC - ANSWERFluoroiodocarbon
PFC - ANSWERperfluorocarbon
Halons - ANSWERInclude Halon 1211 and 1301 and mixtures of the two
Halon 1301 - ANSWERBromotrifluoromethane
Halon 1211 - ANSWERBromochlorodifluoromethane
Hydrostatic testing - ANSWERPressure testing of the extinguisher to verify its
strength against unwanted rupture.
Loaded Stream Charge - ANSWERA water based extinguishing medium that uses an
alkali metal salt as a freezing point depressant.
Extinguisher service pressure - ANSWERThe normal operating pressure as indicated
on the nameplate or cylinder of a fire extinguisher
Factory test pressure - ANSWERThe pressure shown on the nameplate at which a
shell was tested at time of manufacture.
wetting agent - ANSWERA concentrate which, when added to water reduces the
surface tension and increases its ability to penetrate and spread
Water Mist Fire Extinguisher - ANSWERA fire extinguisher containing "distilled or de-
ionized" water and employing a nozzle that discharges the agent in a fine spray
