Combustibility and flammability. A combustible material is a material that can burn (i.e., sustain a flame) in air under certain conditions. A material is flammable if it ignites easily at ambient temperatures. In other words, a combustible material ignites with some effort and a flammable material catches fire immediately on exposure to flame.
On September 3, 1991, an industrial fire caused by a failed improvised repair to a hydraulic line destroyed the Imperial Food Products chicken processing plant in Hamlet, North Carolina. Despite three previous fires in 11 years of operation, the plant had never received a safety inspection. The fire killed 25 people and injured 54, many of whom ...
Polystyrene. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Polystyrene (PS) / ˌpɒliˈstaɪriːn / is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. [5] Polystyrene can be solid or foamed.
Brominated flame retardants (BFRs) are organobromine compounds that have an inhibitory effect on combustion chemistry and tend to reduce the flammability of products containing them. The brominated variety of commercialized chemical flame retardants comprise approximately 19.7% of the market. They are effective in plastics and textile ...
Spontaneous combustion or spontaneous ignition is a type of combustion which occurs by self-heating (increase in temperature due to exothermic internal reactions), followed by thermal runaway (self heating which rapidly accelerates to high temperatures) and finally, autoignition. [1] It is distinct from (but has similar practical effects to ...
Phase-out of polystyrene foam. In the late 20th and early 21st century, there has been a global movement towards the phase-out of polystyrene foam as a single use plastic (SUP). Early bans of polystyrene foam intended to eliminate ozone-depleting chlorofluorocarbons (CFCs), formerly a major component. Expanded polystyrene, often termed ...
Fire triangle. 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 ...
