Across
  1. 3. 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.
  2. 7. 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.
  3. 13. the process of determining the origin, cause and responsibility as well as the failure analysis of fire or explosion.
  4. 14. the lowest temperature at which liquid fuel produces a flammable vapor.
  5. 17. intentional or malicious destruction of property by fire.
  6. 18. 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.
  7. 19. the exact physical location where a heat source and fuel comes in contact with each other and a fire begins.
  8. 24. heat is transferred if the form of electromagnetic energy directly from one object to another.
  9. 28. the active principle of burning characterized by the heat and light of combustion.
  10. 29. any liquid which causes fire when in contact with organic matter or with certain chemicals.
  11. 30. any act that would remove or neutralize fire hazard.
  12. 31. 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.
  13. 32. a return to flaming combustion after incomplete extinguishment of a fire reigning at some time after being put out.
  14. 33. Fuel,Oxygen,Heat
  15. 36. the circumstances or agencies that bring a fuel and an ignition source together with proper air or oxygen.
  16. 42. the movement of fire from one place to another.
  17. 43. any material or mixture consisting of a fuel and oxidizer used to set off explosives.
  18. 45. is a measure of the amount of energy a specific type of fuel can contribute to the heat flux in a fire.
  19. 47. any person who acts as agent of the owner and manages the use of a building for him.
  20. 48. he ease at which a material can be ignited.
Down
  1. 1. a continuous passageway for the transmission of air.
  2. 2. 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.
  3. 4. chipping or pitting of concrete or masonry surfaces.
  4. 5. 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.
  5. 6. any liquid having a flash point at or above 37.8 degrees Celsius or 100 degrees Fahrenheit.
  6. 8. the temperature at which a fuel will ignite on its own with out any additional source ignition.
  7. 9. a fire that spreads with extreme rapidity such as the one that races over dust, over the surface of flammable liquids or through gases.
  8. 10. - a vertical panel of non-combustible or fire resistive materials attached to and extending below the bottom chord of the roof trusses, to divide the underside of the roof into separate compartments so that heat and smoke will be directed upwards to a roof vent.
  9. 11. removal of any of these results in the suppression of the fire.
  10. 12. a hot piece or lump that remains after a material has partially burned and is still oxidizing without the manifestation of flames.
  11. 15. any plastic substance,materials or compound having cellulose nitrate as base.
  12. 16. a highly combustible and explosive compound produced by the reaction of nitric acid with a cellulose material.
  13. 18. 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.
  14. 20. ex. infrared radiation from the sun.
  15. 21. .Descriptive of materials that are easily set on fire.
  16. 22. exothermic reaction involving the oxidation of some substance (fuel) resulting in the release of energy in the form of light and heat.
  17. 23. a finely powdered substance which when mixed with air in the proper proportion and ignited will cause an explosion.
  18. 25. transfer of heat through physical movement of materials and occurs only in liquids and gases.
  19. 26. Hot gases rise and spread heat to nearby ceilings and walls.
  20. 27. a building unsafe in case of fire because it will burn easily or because it lacks adequate exits or fire escapes.
  21. 31. Fuel,Oxygen,Heat,Ignition energy
  22. 34. a fire restrictive door prescribed for openings in fire separation walls or partitions.
  23. 35. 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.
  24. 37. Descriptive of materials that are easily set on fire
  25. 38. 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.
  26. 39. the mechanism in which fire can spread from its origin to other sources of fuel.
  27. 40. materials used as final coating of a surface for ornamental or protective purposes.
  28. 41. a normally open device installed inside an air duct system which automatically closes to restrict the passage of smoke or fire.
  29. 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.
