Foam concentrate

  • AFFF (Aqueous Film Forming Foam): A foam concentrate containing flour chemical surfactants that control the physical properties of water enabling it to float and spread across the surface of the   hydrocarbon
  • Alcohol Resistant (AR): A foam concentrate for use on polar solvents in addition to hydrocarbons.
  • Alcohol Resistant Aqueous Film-Forming   Foam (AR- AFFF):  AFFF that is suitable for use   on polar solvents in addition to hydrocarbons.
  • Alcohol Resistant Film-Forming Fluor protein (AR­ FFFP): FFFP that is suitable for use on polar solvents as well as hydrocarbons.
  • Fluor protein (FP): A natural protein-based   foam concentrate   containing  fluorocarbon  surfactants  that provide  a fuel  shedding  property  to  the  finished  foam. Extensively u s e d in oil a n d petro c he m ictal Indus tries. (See oleo phobic).
  • Class A Fire: A fire in materials such as  wood and paper where  the cooling effect  of water  or  Class  A foam  is of paramount  importance in extinguishing  the  fire. Fires that occur in ordinary combustible materials, i.e. wood, paper, rubber, and certain plastics, etc. (NFPA 10 definition).
  • Class a Foam: Foam specially formulated for use on Class A fires. Essentially wetting agents   that reduce the surface   tension   of   water   and   allow   it to   soak   into combustible materials easier than plain water.
  • Class B Fire: A fire involving a flammable liquid where a blanket or smothering effect is of first importance in extinguishment (CEN definition). Fires which occur in flammable liquids, oils,    tars,     lacquers,     etc.     And flammable gases (NFPA 10 definition).  Fires in flammable and combustible liquids, gases, and greases (UL 162 definition).
  • Class B Foam: Foam formulated to be used on fires or spills of flammable and combustible liquids.
  • Class C Fire – USA: A fire in “live” electrical equipment where the use of non-conducting fire suppression agents is of prime importance.
  • Class C Fire – EUROPE: Fires involving gases or liquefied gases in the form of in the form of a liquid spillage, or a liquid or gas leak (CEN definition).
  • Class D Fire:   A fire   involving a   metal   such    as magnesium,   sodium, lithium, etc.   (CEN definition). Fires that occur   in metals such   as   magnesium,   zirconium, lithium, etc. (NFPA 10 definition).
  • Class E Fire   –   Europe:   A   fire   in   ‘live’   electrical equipment where the use of non-conducting fire suppression agents is of prime importance.
  • Aqueous Film-Forming Foam (AFFF):  Pronounced A­FFF. A synthetic foam concentrate containing detergent and fluorocarbon surfactant that forms a foam capable of producing a vapor-suppressing aqueous film on the surface of some hydrocarbon fuels.  Provides rapid flame knockdown for aircraft crash fires.  Developed in the 1960s, by the Naval Research Laboratory (NRL) in association with the 3M Company.
  • AFFF -Polar (AR-AFFF):  An  AFFF  that   contains a polysaccharide material  that  forms  a polymeric  layer  or film only on  polar  solvents to separate and  protect  the finished  foam.
  • Film-Forming: A foam concentrate   containing  fluorocarbon surfactants  that  has   a  spreading  coefficient  greater  than zero  and  so forms a  foam capable of  producing  a vapor- suppressing aqueous  film  on  the  surface  of  most hydrocarbon fuels.
  • Film-Forming Fluor protein (FFFP): Pronounced Triple F. A natural protein-based foam  concentrate   containing additional   fluorocarbon   surfactants  that   forms   a   foam capable  of producing  a vapor suppressing  aqueous  film on the surface of some hydrocarbon fuels .
