Fire Extinguishers

Fire Extinguishers

American Fire Protection, Inc. carries a variety of Fire Extinguisher types. Each type is best suited to different classes of fire and different environments.

Class A fires are those caused by “ordinary combustibles such as wood, paper, etc.; these fires are commonly fought by removing one of the three components (heat, fuel and oxygen) required to sustain the reaction. Class B fires are caused by flammable or combustible liquids or gaseous fuels. Class C fires are electrical fires or fires where an electrical hazard may be present. Class D fires are flammable metal fires. Class K fires are “kitchen grease” fires caused by cooking oil or fat.

Please review the following information to choose the type best suited to your needs.

Clicking the link for each category will take you to the ordering information for that type of extinguisher.

• Multipurpose Dry Chemical powder extinguishers are effective against Class A fires by melting at 350^oF to coat the surface to which it is applied, Class B fires by smothering and breaking the chain reaction, and does not conduct electricity when applied to Class C fires.
• Regular Dry Chemical powder extinguishers are a more economical solution against Class B and C fires, with a free flowing, non-caking dry chemical that is non-conductive.
• Sodium Chloride (NaCl) dry powder extinguishers can be used against Class D fires to form a crust that prevents oxygen from reaching the blaze and dissipating heat away from burning metal.
• Copper (Cu) dry powder extinguishers operate by the same mechanisms as NaCl extinguishers, but have been found to be superior to other extinguishers for Class D fires caused by Lithium.
• Wet Chemical extinguishers are designed specifically for Class K fires, leaving no chemical residue to clean up.
• Halotron extinguishers use a non-conducive “clean agent” chemical that is a rapidly evaporating non-conductive liquid that leaves no residue. It is effective against Class A, B and C fires in computer areas and clean rooms.

  Class D

• Carbon Dioxide (CO₂) extinguishers use a non-contaminating, odorless gas commonly used in industrial settings to smother Class B fires by eliminating oxygen and is non-conductive when used against Class C fires.
• AFFF extinguishers (Aqueous Film Forming Foam) for Class A and B fires, which leave a sealing film over the flammable material to prevent potential re-ignition of vapors, and can be used preemptively on flammable liquid spills to prevent ignition.
• FFFP extinguishers (Film Forming Fluoroprotein) for Class A and B fires, which flows more slowly than AFFF, leaving a heavier, more smothering foam blanket over a smaller area.
• “Purple K” extinguishers, which contain a specially fluidized potassium-based dry chemical which is particularly effective against Class B fires and is electrically non-conductive.
• Water Mist extinguishers for use against Class A fires where a Class C hazard exists. The nozzle creates a fine mist that protects the user against electrical shock while soaking a larger area to prevent fire spread. Available with a non-magnetic canister and bracket for safe use in clean room and MRI settings.

Each of these extinguisher types is available in a variety of sizes to meet specific applications. Because the extinguishers will be shipped direct from the factory, we will be unable to estimate freight until the order has been placed.
