Across
- 1. rapid oxidation process with the evolution of light and heat in varying intensities
- 4. First Ignited/The fuel that is first set on fire by the heat of ignition. To be meaningful, both a type of material and a form of material should be identified
- 7. transformation of a compound into one or more substances by heat alone. Often preceeds combustion
- 9. crater-like indentation created at the point of origin of an explosion
- 11. of burning with a flame
- 14. Layer/A bouyant layer of hot gases and smoke produced by fire in a compartment
- 15. agent, often an ignitable liquid, used to initiate or speed the spread of a fire
- 18. measurement of energy release rate
- 22. Circuit/An abnormal connection of low resistance between normal circuit conductors where resistance is normally much greater. This is an overcurrent situation but not an overload.
- 24. resulting from self-heating. Synonymous with spontaneous ignition.
- 25. crime of maliciously and intentionally, or recklessly, starting a fire or causing an explosion. Precise legal definitions vary among jurisdictions, wherein it is defined by statutes and judicial decisions
Down
- 2. Energy/The quantity of heat energy that must be absorbed by a substance to ignite and burn
- 3. Fire/A fire that spreads rapidly through a diffuse fuel, such as dust, gas, or vapors of an ignitable liquid, without the production of a damaging pressure
- 5. of Explosion
- 6. of Origin/The room or area where a fire began
- 8. without flame, usually with incandesence
- 10. airborne particulate product of incomplete combustion suspended in gases, vapors, or solid and liquid aerosols
- 12. Scene Reconstruction/The process of recreating the physical scene during fire scene analysis through the removal of debris and the replacement of contents or structural elements in their pre-fire positions
- 13. form of energy characterized by vibration of molecules and capable of initiating and supporting chemical changes and changes of state
- 16. reaction in which the velocity of the reaction front through the unreacted fuel medium is equal to or greater than the speed of sound
- 17. the existence of a fire, especially by a detector, from one or more products of the fire, such as smoke, heat, ionized particles, infrared radiation, and the like
- 19. transfer by way of electromagnetic energy
- 20. chemical compound, mixture, or device the primary purpose of which is to function by explosion
- 21. Products/Heat, gases, solid particulates, and liquid aerosols produced by burning.
- 22. Explosion/Any subsequent explosion resulting from an initial explosion
- 23. Method/The systematic pursuit of knowledge involving the recognition and formulation of a problem, the collection of data through observation and experiment, and the formulation and testing of a hypothesis
