NFPA 10 Portable Fire Extinguisher Exam
ACTUAL QUESTIONS AND CORRECT
ANSWERS
ANSI - CORRECT ANSWERS✅✅American National Standards Institute
Carbon Dioxide - CORRECT ANSWERS✅✅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 ANSWERS✅✅Wet and Dry
Wet Chemical - CORRECT ANSWERS✅✅Normally an aqueous solution of organic or
inorganic salts or a combination thereof that forms an extinguishing agent
Dry Chemical - CORRECT ANSWERS✅✅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 ANSWERS✅✅Cylinders containing nitrogen,
compressed air, carbon dioxide, or other gases at a pressure higher than 500 psi at 70 degrees
Dry Powder - CORRECT ANSWERS✅✅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 ANSWERS✅✅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 ANSWERS✅✅Aqueous film-forming foam
(AFFF) and film forming fluoroprotein foam (FFFP)
