NFPA 10 Latest Update with Verified
Solutions
ANSI ✔✔American National Standards Institute
Antifreeze Charge ✔✔Loaded stream charge
Carbon Dioxide ✔✔A colorless, odorless, electrically non-conductive inert has that is a suitable
medium for extinguishing class B and class C fires
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
Wet Chemical ✔✔Normally am aqueous solution of organic or inorganic salts or a combination
there of that forms an extinguishing agent

Wet Chemical ✔✔Normally am aqueous solution of organic or inorganic salts or a combination there of that forms an extinguishing agent

Clean Agent ✔✔Electrically non-conducting, volatile, or gaseous fire extinguishant that does not leave a residue upon evaporation

Dry Chemical Recovery System ✔✔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 ✔✔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 ✔✔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 ✔✔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).

Extinguisher Inspection ✔✔A quick check that a fire extinguisher is in its designated place, that it has not been actuated or tampered with, and that there is no obvious physical damage or condition to prevent its operation.

Extinguisher Maintenance ✔✔A thorough examination of the fire extinguisher that is intended to give maximum assurance that a fire extinguisher will operate effectively and safely and to determine if physical damage or condition will prevent its operation, if any repair or replacement is necessary, and if hydrostatic testing or internal maintenance is required.

Film-Forming Foam Agents ✔✔Aqueous film-forming foam (AFFF) and film-forming fluoroprotein foam (FFFP).

Flammable Liquids of Appreciable Depth ✔✔Flammable liquids of appreciable depth are those with a depth greater that 1/4 in. (6.3 mm).

Halogenated Agents ✔✔Halogenated (clean) agents

Halocarbons ✔✔Halocarbon agents include hydrochlorofluorocarbon (HCFC), hydrofluorocarbon (HFC), perfluorocarbon (PFC). fluoroiodocarbon (FIC), types of agents, and

other halocarbons that are found acceptable under the Environmental Protection Agency Significant New Alternatives Policy program.

Halons ✔✔Halons include bromochlorodifluoromethane (Halon 1211), bromotrifluoromethane (Halon 1301), and mixtures of Halon 1211 and Halon 1301 (Halon 1211/1301)

Hydrostatic Testing ✔✔Pressure testing of the extinguisher to verify its strength against unwanted rupture

Loaded Stream Charge ✔✔A water based extinguishing agent that uses alkali metal salt as a freezing point depressant

Mild Steel Shell ✔✔All steel shells other than stainless steel and steel shells used for high pressure cylinders

Extinguisher Service Pressure ✔✔The normal operating pressure as indicated on the nameplate or cylinder of a fire extinguisher
