100% Pass
ANSI - ANSWER-American National Standards Institute
Antifreeze Charge - ANSWER-Loaded stream charge
Carbon Dioxide - ANSWER-A colorless, odorless, electrically non-conductive
inert has that is a suitable medium for extinguishing class B and class C fires
Dry Chemical - ANSWER-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 (caking), and the proper flow
capabilities
Wet Chemical - ANSWER-Normally am aqueous solution of organic or inorganic
salts or a combination there of that forms an extinguishing agent
Clean Agent - ANSWER-Electrically non-conducting, volatile, or gaseous fire
extinguishant that does not leave a residue upon evaporation

, Dry Chemical Recovery System - ANSWER-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.
Halogenated Closed Recovery System - ANSWER-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
into the atmosphere. Closed recovery systems for halogenated agents with an
ozone depleting potential (ODP) of 0.2 or greater should be listed for use with that
agent. The system's supply or recharge and recovery container is capable of
maintaining the agent in a sealed environment until it is reused or returned to the
agent manufacturer
High Pressure Cylinder - ANSWER-Cylinders (and cartridges) containing nitrogen,
compressed air, carbon dioxide, or other gases at a pressure higher than 500 psi
(3447 kPa) at 70°F (21°C).
Low Pressure Cylinder - ANSWER-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).
