NFPA 10 PORTABLE FIRE EXTINGUISHER EXAM QUESTIONS
AND ANSWERS
ANSI - CORRECT ANSWER✅✅American National Standards Institute
Carbon Dioxide - CORRECT ANSWER✅✅A colorless, odorless, electrically non conductive inert gas that
is a suitable medium for extinguishing Class B and Class C fires
2 types of chemical - CORRECT ANSWER✅✅Wet and Dry
Wet Chemical - CORRECT ANSWER✅✅Normally an aqueous solution of organic or inorganic salts or a
combination thereof that forms an extinguishing agent
Dry Chemical - CORRECT 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
High Pressure Cylinder - CORRECT ANSWER✅✅Cylinders containing nitrogen, compressed air, carbon
dioxide, or other gases at a pressure higher than 500 psi at 70 degrees
Dry Powder - CORRECT ANSWER✅✅Solid materials in powder or granular form designed to extinguish
Class D combustible metal fires by crusting, smothering, or heat-transferring means
Extinguisher Inspection - CORRECT ANSWER✅✅A quick check that a fire extinguisher is in its designated
place, that it has not be actuated or tampered with, and that there is no obvious physical damage or
condition to prevent its operation
Film-forming foam agents - CORRECT ANSWER✅✅Aqueous film-forming foam (AFFF) and film forming
fluoroprotein foam (FFFP)
Appreciable depths - CORRECT ANSWER✅✅Depth greater than a quarter inch
