main priority for fire fighters. They may have to damage parts of the scene to save or protect lives. The majority of the evidence get destroyed or lost from the activities done by fire service. That result in the spoliation, contamination, removal, loss, unnecessary movement of physical evidence, complication of the scene and detraction of the evidence validity. Therefor it becomes harder for fire investigators to figure and conduct testing on what was responsible for the fire. (David J. Icove…

burn a candle within sight, to keep them out of reach of children, and to keep them away from things that could catch fire. The Heat Strength of Glass Containers Standard (ASTM F-2179) establishes a scratch test and temper specifications for the proper annealing of glass containers used for candles. This standard also established the thermal shock differential requirements. The Fire-Safety Design Standard (ASTM F-2417) establishes the maximum flame height, tip-over limits, secondary-ignition…

Fire Behaviour Moisture: Background Information: With some parts of Australia being extremely prone to bushfires, ways to prevent them and understand them are vital.
