Fire Technology and Arson Investigation
Across
- 4. refers to the crime f intentionally setting fire to a building or other property.
- 8. the final phase of burning wherein flame ceases but dense smoke and heat completely fill the confined room.
- 11. transmission of heat through the medium of heat rays or heat waves.
- 12. it is a device used for making a connection when threads do not match or when they are different in sizes.
- 14. rapid oxidation of combustible materials accompanied by the released of energy in the form of heat and light.
- 17. transfer of heat from one body to another by direct contact.
- 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.
- 24. simply means the spread of fire.
- 26. measure of thermal degree of agitation of the molecules of a given substance the measure of the molecular activity within a substance.
- 27. fluids that do not generate more than 40 psia when heated to 100 degrees F. (psia is pound per-square inch absolute).
- 28. form of energy generated by the transmission of some other form of energy, as in combustion or burning
- 30. the cooling process uses an extinguishing agent whose primary characteristic is heat absorption. Water is the best general cooling agent for firefighting purposes.
- 32. useful in man’s existence in planet Earth.
- 33. the basic level of training for emergency response to a chemical accident, the ability to recognize a hazardous situation and call for assistance.
- 35. excludes the oxygen from the fuel so that the gases or vapors of the fuel cannot ignite and continue the combustion.
- 36. it is the initial stage of fire.
- 39. the second phase of burning in which materials or structures are burning in the presence of adequate oxygen.
- 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.
- 43. main structural member of a ladder supporting the rungs or rung block.
- 44. defensive method of controlling a spill by applying a material that absorbs the spilled chemical.
- 45. the manifestation of fire when the fire is in its gas-phased combustion.
- 46. putting the fire completely out.
- 48. any substance which reacts chemically with oxygen and produces flames.
- 49. science that deals with the study of matter and energy and their mutual interactions.
Down
- 1. used on Class A fires. Water is the most effective in cooling the burning material below its ignition temperature.
- 2. colorless, odorless gas and one of the compositions of air which is approximately 21 % by volume.
- 3. rapid burning, which can be considered a slow explosion, but travels at a lesser speed than a detonation.
- 5. chemical change in which combustible material (fuel) and an oxidizing agent react.
- 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.
- 7. chemical process reaction caused by oxidation that produces heat and light.
- 9. the actual physical fire fighting operation utilizing available manpower and equipment.
- 10. fire cause as a result of the willful and criminal action of some persons i.e incendiary fire.
- 12. Aqueous Film Forming Foam has replaced protein foam for all around firefighting purposes.
- 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
- 15. transfer of heat by circulation of heated currents of liquids and gases.
- 16. these are smallest particles of elements that take part in a chemical reaction.
- 18. physical removal of contaminants (chemicals) from people, equipment, or the environment.
- 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.
- 20. manner or action of a substance or organism under a specific sets of condition.
- 21. measure of thermal degree of agitation of the molecules of a given substance the measure of the molecular activity within a substance.
- 22. means keeping the fire from spreading or holding the fire to one area.
- 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.
- 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.
- 31. means the size of a fire, and it is governed by the surface area of fuel exposed to the air.
- 34. fire caused naturally without human intervention or aid; such as lightning, spontaneous ignition and mechanical malfunction of equipment.
- 37. material that is irritating to humans, but usually does not cause any long-term effects.
- 38. management system used to organize the response to a chemical incident.
- 40. Means simply “how hot the fire is burning” some types of fuels naturally burn hooter (more intensely) than others.
- 41. fire causes where human action is involved directly or indirectly
- 47. These have been used for over 50 years.
