NFPA 10 Portable Fire Extinguisher Exam questions with
complete solutions
ANSI American National Standards
Institute A colorless, odorless,
electrically non
Carbon conductive inert gas that is a
Dioxide suitable medium for
extinguishing Class B and Class
C fires
2 types of chemical Wet and Dry
Normally an aqueous solution of
organic
Wet Chemical or inorganic salts or a combination
there- of that forms an
extinguishing agent
A powder composed of very small
parti- cles, usually sodium
bicarbonate-,potas- sium
Dry Chemical
bicarbonate-, or ammonium phos-
phate based with added particulate
ma- terial supplemented by special
treatment to provide resistance to
packing, resis- tance to moisture
absorption (caking), and the proper
High Pressure flow capabilities
Cylinder Cylinders containing nitrogen,
com- pressed air, carbon dioxide,
or other gas- es at a pressure
higher than 500 psi at 70 degrees
Dry Powder Solid materials in powder or
granu- lar form designed to
extinguish Class D combustible
metal fires by crusting,
smothering, or heat-transferring
Extinguisher means
