fire hazard

• fire - a part of a very rapid, and usually persistent chemical reaction called oxidation
• oxidation - responsible for the brown color that forms on the face of an apple or a potato
• heat - energy that flows from an object of high temperature to an object of low temperature
• fuel - any solid, liquid, or gaseous substance that can be burned
• pyrolysis - chemical decomposition of solid fuels
• vaporization - production of fuel gases from liquid fuels
• oxidizing agent - element or a compound which releases oxygen or other oxidizers
• ignition stage - all four requirements for a fire have been combined
• growth stage - the shortest of the four stages
• fully developed fire - fire has consumed almost all available combustible materials
• decay stage - lasts the longest
• wildfire - any natural or anthropogenic-caused
• ground fire - burning of buried decomposed organic matter
• surface fire - most common type
• crown fires - tree canopies, other higher parts of trees
• ladder fuels - any combustible material found
