NFPA 403-1998 Standard for Aircraft Rescue and Fire-Fighting Services at Airports

NFPA 403-1998 Standard for Aircraft Rescue and Fire-Fighting Services at Airports. Foam Concentrate. A concentrated liquid foaming agent that is mixed with water and air in designated proporions to form foam. Foam, Film-Forming Fluoroprotein (FFFP)。 A protein- based foam concentrate incorporating fluorinated surfactants that forms a foam capable of producing a vapor-suppressing, aqueous film on the surface of hydrocarbon fuels. This foam might show an aceptable level of compatibility to dry chemi- cals and might be suitable for use with those agents. Foam, Fluoroprotein (FP)。A protein-based foam concen- trate with added fluorochemical sur factants that forms a foam showing a measurable degree of compatibility with dry chemi- cal extinguishing agents and an increase in tolerance to con- tamination by fuel. Foam, Protein (P)。A protein-based foam concentrate that is stabilized with metal salts to make a fire-resistant foam blan- ket. Foam Solution. The solution that resuls when foam con- centrate and water are mixed in designated proportions prior to aerating to form foam. Fuselage. The main body of an aircraft. International Civil Aviation Organization (ICAO)，An in- ternational body charged with matters dealing with the devel- opment, coordination, and preservation of international civil aviation. Movement Area. Those parts of the airport used for taxi- ing, takeoff, and landing of aircraft, exclusive of parking areas. Mutual Aid. Reciprocal assistance by emergency services under a prearranged plan. Rapid Response Area (RRA).* A rectangle that includes the runway and the surrounding area extending to but not beyond the airport property linc. Its width extends 500 ft (152 m) outward from each side of the runway centerline, and its length is 1650 ft (500 m) beyond each runway end. (See Figure A-1-3.) Shall. Indicates a mandatory requirement. 3-3 Quantity of Agents. 3-3.1* The minimum amounts of water for foam production, and the minimum amounts of complementary agents neces- sary shall be as specified in Tables 3-3.1 (a)or 3-3.1 (b) based on the system of categorizing airports listed in Table 2-3.1. 3-3.2 Sufficient foam concentrate shall be provided to pro- portion, at the prescribed percentage of foam concentrate to water, into double the quantity of water specified in Table 3-3.1(a) or 3-3.1(b). 3-3.3* Water equal to 100 percent of that required by 3-8.1 shall be available to replenish the primary fire fighting vehice(s). 3-4* Compatibility of Agents. Chemical compatibility shall be ensured between foam and complementary agents where used simultancously or consecutively. 3-5* Combustible Metal Agents. Extinguishing...
