- 14. - it is a manner or action of a substance or organism under a specific sets of condition.
- 18. - it is the manner in which fuel ignites, flame develops, and fire spreads. Sometimes used to distinguish characteristics of one particular fire from typical fire characteristics.
- 20. - it is the transfer of heat by circulation of heated currents liquids and gases.
- 21. – (smooth flame) flame is laminar when particle follows a smooth path through a gaseous flame.
- 22. - the transfer of heat from one body to another by direct contact (electric stove electrode to utensil), within the same body (metal rod heated at one end).
- 25. - a specially constructed, tested, and approved door installed for the purpose of preventing the spread of the fire.
- 27. - the temperature at which a material is not hot enough to keep burning, but still gives off enough vapors to cause a flame to “flash” across the surface.
- 28. - these are smallest particles of elements that take part in a chemical reaction.
- 29. - the official report of a fire, generally prepared by the person in-charge of the fire incident.
- 30. - a chemical change in which combustible material (fuel) and an oxidizing agent react.
- 32. - it refers to the crime f intentionally setting fire to a building or other property. The willful and malicious burning of the property of another.
- 33. - materials including petroleum products such as gasoline, fuel oils, lubricating oils, and greases; animal fats such as butter, lard, and tallow; vegetable extracts such as alcohol, linseed oil, and turpentine; vegetable compounds such as shortening and oleomargarines; natural gases and compressed gases such as butane, propane, hydrogen, and acetylene.
- 34. – excludes the oxygen from the fuel so that the gases or vapors of the fuel cannot ignite and continue the combustion. CO2 and AFFF are used for this purpose.
- 37. - the ratio of the weight of a solid or substance to the weight of an equal volume of water.
- 40. - the weight of a volume of pure gas compared to the weight of a volume of dry air at the same temperature and pressure.
- 43. – estimate the situation.
- 44. - 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.
- 45. - conditions that are conducive to fire or are likely to increase the extent of severity of fire.
- 46. - materials involving vegetable fibers, wood, paper straw, grain, and grass; combustible minerals such as coal and coke. Nearly all trash fires are considered as Class
- 47. - it is the main structural member of a ladder supporting the rungs or rung block.
- 48. - it is the 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.
- 50. - fire caused naturally without human intervention or aid; such as lightning, spontaneous ignition and mechanical malfunction of equipment.
Down
- 1. - a colorless, odorless gas and one of the compositions of air which is approximately 21 % by volume.
- 3. - the movement and dispersion of heat by conduction, radiation, or convection.
- 4. - a form of energy generated by the transmission of some other form of energy, as in combustion or burning.
- 5. - it is any department of knowledge in which the results of investigation have been systematized in the form of hypotheses and general laws subject to verification.
- 6. - material and design of building construction meant to withstand the maximum effect of fire for a specific duration or period of time.
- 9. - fire protection activities that deal with preventing fires from starting by eliminating fire hazards through inspection and education programs.
- 11. - it is the rapid oxidation of combustible materials accompanied by the released of energy in the form of heat and light.
- 12. – example of flame of the oxyacetylene torch (diffused-dispersed; widely spread).
- 15. - it is the actual physical fire fighting operation utilizing available manpower and equipment. The implementation of tactical plans on the fire ground in an aggressive manner.
- 16. - process uses an extinguishing agent whose primary characteristic is heat absorption.
- 17. - the force exerted by the molecules on the surface of the liquid at equilibrium.
- 19. - the temperature at which the material will give off ample vapors to keep burning.
- 23. - it is a chemical process reaction caused by oxidation that produces heat and light.
- 24. - firecauses where human action is involved directly or indirectly. i.e a) careless disposal of smoking materials, b) workers using welding-cutting equipment
- 26. - the transmission through the discharge and spread of heat from a heated or burning source.
- 31. - fire cause as a result of the willful and criminal action of some persons, i.e incendiary fire.
- 35. - the measure of thermal degree of agitation of the molecules of a given substance; the measure of the molecular activity within a substance.
- 36. it is the science that deals with the study of matter and energy and their mutual interactions.
- 38. – example of a Bunsen burner.
- 39. - these are materials involving combustible metals, alloys, or metal compounds either in a solid, semi-solid or liquid state. They may further reduce in shavings, grindings, granules, or dust.
- 41. - the transmission of heat through the medium of heat rays or heat waves.
- 42. - the 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. If fuel is not available then heat, regardless of the temperature, cannot affect the fuel, therefore, there is no fire.
- 49. - any substance which reacts chemically with oxygen and produces flames.
