Accelerator (chemistry)




An accelerant (or '''accelerator''') is any substance that increases the rate of a chemical reaction, such as Oxidation or the Curing of an Adhesive . Conversely, a decelerant (or Retarder ) inhibits the rate of a Chemical Reaction . A fire is an Exothermic oxidation reaction that when accelerated produces more heat, consumes the reactants more quickly, burns at a higher temperature, and increases the spread of the fire. Some fire investigators use the term "accelerant" to mean any substance that initiates and promotes a fire implying ''no'' intent or use.

Presence of accelerants on the scene is commonly investigated when arson is suspected. Specially trained , Diesel Fuel , Kerosene , Turpentine , Butane , and various other Flammable Solvent s.
