NFPA 10 Portable Fire Extinguisher
Exam with Complete Solutions
ANSI ✔✔American National Standards Institute
Carbon Dioxide ✔✔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 ✔✔Wet and Dry
Wet Chemical ✔✔Normally an aqueous solution of organic or inorganic salts or a combination thereof that forms an extinguishing agent
Dry Chemical ✔✔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 ✔✔Cylinders containing nitrogen, compressed air, carbon dioxide, or other gases at a pressure higher than 500 psi at 70 degrees
Dry Powder ✔✔Solid materials in powder or granular form designed to extinguish Class D combustible metal fires by crusting, smothering, or heat-transferring means
Extinguisher Inspection ✔✔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 ✔✔Aqueous film-forming foam (AFFF) and film forming fluoroprotein foam (FFFP)
Appreciable depths ✔✔Depth greater than a quarter inch
Halocarbons ✔✔Halocarbon agents include hydrochlorofluorocarbon (HCFC), hydrofluorocarbon (HFC), perfluorocarbon (PFC), and fluoroiodocarbon (FIC) types of agents
Halons ✔✔Halons include bromochlorodifluoromethane ( Halon 1211), bromotrifluoroethane (Halon 1301), and mixtures of Halon 1211 and Halon 1301 ( Halon 1211/1301)
Pressurized water fire extinguishers manufactured prior to 1971
Any extinguisher that needs to be inverted to operate
Any stored pressure extinguisher manufactured prior to 1955
Any extinguishers with 4b, 6b, 8b, 12b, and 16b fire ratings
Stored pressure water extinguishers with fiberglass shells (pre-1976)
Classifying Occupancy Hazard ✔✔Rooms or areas shall be classified as being light (low) hazard, ordinary (moderate) hazard, or extra (high) hazard
Light (low) hazard ✔✔locations where the quantity and combustibility of Class A combustibles and Class B flammables are low and fires with relatively low rates of heat release are expected. These occupancies of fire hazards having normally
