The development of NFPA 704 is credited to the Charlotte Fire Department after a fire at the Charlotte Chemical Company in 1959 led to severe injuries to many of the firefighters. [4] [5] Upon arrival, the fire crew found a fire burning inside a vat that firefighters assumed to be burning kerosene. The crew tried to suppress the fire, which ...
The fire triangle or combustion triangle is a simple model for understanding the necessary ingredients for most fires. [1] The triangle illustrates the three elements a fire needs to ignite: heat, fuel, and an oxidizing agent (usually oxygen). [2] A fire naturally occurs when the elements are present and combined in the right mixture. [3]
Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. [1] [a] Flames, the most visible portion of the fire, are produced in the combustion reaction when the fuel reaches its ignition point.
Principal among these is a 16-point list of areas in which a fire investigator is required to have education beyond high school level. The list mentions points such as using protective equipment, fire ignition, heat science, explosions, working with chemicals, investigating fires, using related technology, and reporting evidence.

These settings are normally available as templates in chemical drawing programs. Use sans-serif fonts like Arial. Indexes used for labelling must be superscripted: R 1-CH 2-R 2 (not R 1-CH 2-R 2) Do not include English text in images: this prevents their reuse in other languages.
Fire engineers, like their counterparts in other engineering and scientific disciplines, undertake a formal course of education and continuing professional development to acquire and maintain their competence. This education typically includes foundation studies in mathematics, physics, chemistry, and technical writing.
A fire class is a system of categorizing fire with regard to the type of material and fuel for combustion.Class letters are often assigned to the different types of fire [1], but these differ between territories; there are separate standards for the United States (NFPA 10 Chapter 5.2.1-5.2.5), Europe (DIN EN2 Classification of fires (European Standard) ISO3941 Classification of fires ...
