  2. 2. .Descriptive of materials that are easily set on fire.
  3. 3. intentional or malicious destruction of property by fire.
  4. 4. any readily ignitable and free burning fiber such as cotton,oakum,rags,waste cloth,waste paper,kapok,hay,straw,Spanish moss,excelsior,and other similar materials commonly used in commerce.
  5. 5. the active principle of burning characterized by the heat and light of combustion.
  6. 6. the circumstances or agencies that bring a fuel and an ignition source together with proper air or oxygen.
  7. 7. the lowest temperature at which liquid fuel produces a flammable vapor.
  8. 9. any person who acts as agent of the owner and manages the use of a building for him.
  9. 11. the process of determining the origin, cause and responsibility as well as the failure analysis of fire or explosion.
  10. 13. a continuous passageway for the transmission of air.
  11. 14. or burning - is the sequence of exothermic chemical reaction between fuel and an oxidant accompanied by the production of heat and conversion of chemical species.
  12. 16. the density of the vapor relative to the density of air and is calculated by dividing the molecular weight of the gas by that of air.
  13. 19. chipping or pitting of concrete or masonry surfaces.
  14. 21. a normally open device installed inside an air duct system which automatically closes to restrict the passage of smoke or fire.
  15. 23. descriptive of any material which by its nature or as a result of its reaction with other elements produces a rapid drop in temperature of the immediate surroundings.
  16. 24. a building unsafe in case of fire because it will burn easily or because it lacks adequate exits or fire escapes.
  17. 25. the mechanism in which fire can spread from its origin to other sources of fuel.
  18. 27. any act that would remove or neutralize fire hazard.
  19. 29. an extremely hot luminous bridge formed by passage of an electric current across a space between two conductors or terminals due to the incandescence of the conducting vapor.
  20. 31. the lowest temperature at which liquid fuel produces a flammable vapor in sufficient quantity such that if a source of ignition is introduced, the vapor will ignite and is usually a few degrees above the flash point.
  21. 32. a finely powdered substance which when mixed with air in the proper proportion and ignited will cause an explosion.
  22. 34. he ease at which a material can be ignited.
  23. 36. the movement of fire from one place to another.
  24. 37. heat is transferred by direct contact and the rate of transfer is dependent on factors such as the thermal conductivity of the material and the temperature difference between the cooler and warmer areas.
  25. 41. the total quantity of combustible contents of the building, spaces or fire area, including interior finish and trim expressed in heat units or the equivalent weight in wood.
  26. 42. any visual or audible signal produced by a device or system to warn the occupants of the building or the fighting element of the presence or danger of fire to enable them to undertake immediate action to save life and property and to suppress the fire.
  27. 44. the process of first raising the temperature to separate the more volatile from the less volatile parts and then cooling and condensing the resulting vapor so as to produce as nearly purified substance.
