    • The FireBoy 70551 is a 5-Pound Portable Fire Extinguisher that is factory refillable
    • These extinguishers leave no residue whatsoever, unlike dry chemical systems
    • UL Rated 5-B:C (Flammable Liquids / Electrical Fires)
    • Net Contents: 5 lb / USCG Size Rating: B-I
    • Active Agent: Argon Gas
      • A unique feature of these portable fire extinguishers is super pressurization using Argon gas that enables a user to stand as far as ten feet away from a fire
    • The Agent is non-conducive electrically and ideal for flammable liquids including gasoline and diesel fuel as well as galley fires
    • FireBoy® offers extinguishers are the first clean-agent systems in the world to receive U.S. Coast Guard Approval
    • The fire-suppressant agent is a non-conductor of electrical current
      • It provides ideal extinguishing capabilities for flammable fluids including gasoline and diesel fuel
      • It is all fully effective on galley fires
    • Applied directly to engines, it causes no cold shock as with carbon dioxide extinguishers and thus will not damage the engine or component parts
    • Upon release, the agent turns instantly into a heavier-than-air gas
      • As such, it tends to settle and remain in an enclosed space such as an engine compartment
    • Wherever a flammable liquid hazard exists onboard a vessel or in a boatyard or marina, FireBoy® portables should be readily available
    • Includes Coast Guard-Approved mounting brackets and are UL listed

    Fire Extinguisher Class Rating Guide:

    • Class A extinguishers are for ordinary combustible materials such as paper, wood, cardboard, and most plastics. The numerical rating on these types of extinguishers indicates the amount of water it holds and the amount of fire it can extinguish. Geometric symbol (green triangle)
    • Class B fires involve flammable or combustible liquids such as gasoline, kerosene, grease and oil. The numerical rating for class B extinguishers indicates the approximate number of square feet of fire it can extinguish. Geometric symbol (red square)
    • Class C fires involve electrical equipment, such as appliances, wiring, circuit breakers and outlets. Never use water to extinguish class C fires - the risk of electrical shock is far too great! Class C extinguishers do not have a numerical rating. The C classification means the extinguishing agent is non-conductive. Geometric symbol (blue circle)
