High capacity fog foam (HCFF) Combat class bravo fires and introduce the firefighting AFFF into areas most susceptible to conflagration through sprinklers HCFF injections Comprised of 11-20 separate injections stations all of which are located on 2nd and 3rd deck. HCFF component Injection pump provide AFFF concentrate to the sprinkling system and hose reel stations at a pressure in excess of the fire main pressure 1.5 hose GPM 125 2.5 hose GPM 250 Two types of injection pumps Single speed- flight deck, flush deck sprinkler system and flush deck nozzles Two speed- utilized in the HCFF system where more than one sprinkler group or hose are activated Injection pumps delivery 27 - 65 GPM Low rate output- 250 or less High speed output- 250 or greater

Motor control Regulates the speed of its motor and protects it from damage Motor control provides Motor and circuit overload protection and emergency local operation in an overload condition AFFF concentrate tanks Capacity of 600 gallons AFFF depletion time Approximately 5-22 minutes depending on the demand, pumps or a combination of pump units Piping and valves Recirculation Distribution Valves Recirculation Piping is provided for AFFF concentrate during pump unit test, adjustment and shut down. Distribution AFFF concentrate piping from the tank to the injection pumps are normally maintain full Valves Control valves used in the HCFF system are quick acting, corrosion resistant and hydraulically operates Fire deck sprinkler system Consists of flush deck, cannon type, and deck edge nozzles Hangar deck sprinkler system

The individual AFFF sprinkler groups are actuated by controls located in the conflag stations and around the hangar bay Push button Control is located adjacent to each hose station Fire is found in two states Smoldering Flaming Smoldering The beginning and is not growing in size or intensity. Flaming Size and intensity increases to a rapid self-sustaining combustion Elements of fire Heat Fuel Oxygen Heat Produce by a chemical reaction known as oxidation Fuel May be a solid, liquid or even a vapor Oxygen A fire needs oxygen to breath as you do, however your need is around 20 percent and some fires will burn at only 6 percent Alpha

Solid materials. Wood, paper, cloth, or any material that leaves ash Alpha fire extinguishing factor Solid stream water and manually spreading the ashes with a rake or ax Bravo Fuels- gasoline, jet fuel, diesel, alcohol, oils grease , paints, most of which are petroleum base Smothering agent class bravo AFFF, steam and CO2. AFFF offers the most protection against re flash Charlie fires Electrical materials White smoke Smother agents for charlie CO Delta Combustible metals Magnesium, titanium and beryllium are examples combustible materials used in aircraft Smothering agent for delta Water in large quantities such as high velocity fog Controlling of fires Starving Partial extinguishment Total extinguishment Starving Removing or stopping the flow of fuel

Partial extinguishment Primary method used in crash rescue operations Total extinguishment Conducted usually after rescue has been completed Water Primarily a cooling agent, when water hits the fire it is converted into steam, it expands and absorbs heat Never use on class C fires Halon Color gas Discharge temps - 0 to 15 emission factor Chain breaking agent Not effective on class D fires PKP Chain breaking agent Prevent reactive particles from coming together and continuing the combustion chain reaction AFFF mix Two different percentages 6 percent and 3 percent 6 percent 6 parts of AFFF to 94 percent of water 3 percent 3 parts of AFFF to 97 percent of water Carbon dioxide Discharged at temperature of - 110 F with 450 to 1 expansion ratio

Care and maintenance Extinguishers shall be thoroughly examined and recharge/replaced at least once a year. Nitrogen cylinders/cartridges Hydrostatically tested every 5 Years Hydrostatic Test dates Recorded on metal bands or stamped on the cylinder itself Carbon dioxide CO Red in Color with 6 inch yellow band for identification 15 pounds of liquid CO2 discharge time Approximately 8 to 44 seconds Range for CO Approximately 3 to 8 feet Weakest point of CO The neck of the bottle Purple - K- Powder (PKP) 30 pounds Red in color with 6 inch purple band for identification Effective discharge of PKP 10 to 20 feet (10-40 feet) Discharge time for PKP 20 seconds (8-60 seconds) Halon

20 pounds Red in color with 6 inch reflective silver-white band for identification Effective discharge for halon 9 to 15 feet Discharge time for halon 10 to 18 seconds Scene leader Assumes command and directs available firefighting assets to provide a rescue paths Hose team A minimum of five person Hose team members Hose team leader Nozzleman Hoseman Anchorman Biteman Plugman Hose team leader Is responsible for the direction of the hose team Position of the hose team Outside of the hose between hose team members and the scene leader Hose station operator The plug man Bite man

Last man on hose Messengers Responsible for relaying information from the scene leader to flight deck control Notification Reporting of a mishap should be accomplished by the most expeditious method in accordance with the ship operating instruction Avoid submerged objects Pick up your feet Estimated ready deck Scene leader gives estimated ready deck time to pri-fly if salvage operations are not required
