  1. 4. refers to the crime f intentionally setting fire to a building or other property.
  2. 8. the final phase of burning wherein flame ceases but dense smoke and heat completely fill the confined room.
  3. 11. transmission of heat through the medium of heat rays or heat waves.
  4. 12. it is a device used for making a connection when threads do not match or when they are different in sizes.
  5. 14. rapid oxidation of combustible materials accompanied by the released of energy in the form of heat and light.
  6. 17. transfer of heat from one body to another by direct contact.
  7. 23. It is the visible product of incomplete combustion, usually a mixture of oxygen, nitrogen, carbon dioxide, carbon monoxide, finely divided particles of soot and carbon, and miscellaneous assortment of product released from the burning material.
  8. 24. simply means the spread of fire.
  9. 26. measure of thermal degree of agitation of the molecules of a given substance the measure of the molecular activity within a substance.
  10. 27. fluids that do not generate more than 40 psia when heated to 100 degrees F. (psia is pound per-square inch absolute).
  11. 28. form of energy generated by the transmission of some other form of energy, as in combustion or burning
  12. 30. the cooling process uses an extinguishing agent whose primary characteristic is heat absorption. Water is the best general cooling agent for firefighting purposes.
  13. 32. useful in man’s existence in planet Earth.
  14. 33. the basic level of training for emergency response to a chemical accident, the ability to recognize a hazardous situation and call for assistance.
  15. 35. excludes the oxygen from the fuel so that the gases or vapors of the fuel cannot ignite and continue the combustion.
  16. 36. it is the initial stage of fire.
  17. 39. the second phase of burning in which materials or structures are burning in the presence of adequate oxygen.
  18. 42. any department of knowledge in which the results of investigation have been systematized in the form of hypotheses and general laws subject to verification.
  19. 43. main structural member of a ladder supporting the rungs or rung block.
  20. 44. defensive method of controlling a spill by applying a material that absorbs the spilled chemical.
  21. 45. the manifestation of fire when the fire is in its gas-phased combustion.
  22. 46. putting the fire completely out.
  23. 48. any substance which reacts chemically with oxygen and produces flames.
  24. 49. science that deals with the study of matter and energy and their mutual interactions.

  1. 1. used on Class A fires. Water is the most effective in cooling the burning material below its ignition temperature.
  2. 2. colorless, odorless gas and one of the compositions of air which is approximately 21 % by volume.
  3. 3. rapid burning, which can be considered a slow explosion, but travels at a lesser speed than a detonation.
  4. 5. chemical change in which combustible material (fuel) and an oxidizing agent react.
  5. 6. refers to the chemical process whereby fire consumes the most solid part of the fuel. It is the thermal decomposition of a solid fuel through the action of heat.
  6. 7. chemical process reaction caused by oxidation that produces heat and light.
  7. 9. the actual physical fire fighting operation utilizing available manpower and equipment.
  8. 10. fire cause as a result of the willful and criminal action of some persons i.e incendiary fire.
  9. 12. Aqueous Film Forming Foam has replaced protein foam for all around firefighting purposes.
  10. 13. mechanical device usually made of metal, containing chemicals, fluids or gases for stopping fires, the means for application of its contents for the purpose of putting out fire
  11. 15. transfer of heat by circulation of heated currents of liquids and gases.
  12. 16. these are smallest particles of elements that take part in a chemical reaction.
  13. 18. physical removal of contaminants (chemicals) from people, equipment, or the environment.
  14. 19. removal of the fuel, as in the example of turning off a valve in a gas line prevents the fuel and oxygen from coming together.
  15. 20. manner or action of a substance or organism under a specific sets of condition.
  16. 21. measure of thermal degree of agitation of the molecules of a given substance the measure of the molecular activity within a substance.
  17. 22. means keeping the fire from spreading or holding the fire to one area.
  18. 25. occurs when a pressurized tank is heated and the pressure inside the tank exceeds the capacity of the relief valves to handle the pressure.
  19. 29. science that deals with the study of matter which treats of the structure, composition, and properties of substances and of the transformations which they undergo.
  20. 31. means the size of a fire, and it is governed by the surface area of fuel exposed to the air.
  21. 34. fire caused naturally without human intervention or aid; such as lightning, spontaneous ignition and mechanical malfunction of equipment.
  22. 37. material that is irritating to humans, but usually does not cause any long-term effects.
  23. 38. management system used to organize the response to a chemical incident.
  24. 40. Means simply “how hot the fire is burning” some types of fuels naturally burn hooter (more intensely) than others.
  25. 41. fire causes where human action is involved directly or indirectly
  26. 47. These have been used for over 50 years.
