Dry chemical powder is used on all classes of fires. Dry chemical powder puts out the fire by coating the burning material with a thin layer of dust, thereby separating the fuel from the oxygen in the air. The powder also works to interrupt the chemical reaction of fire, so these extinguishers are extremely effective at putting out the fire.
AMS is formed as a by-product of the cumene process. In this procedure, cumene is converted to its radical , through a reaction with oxygen. Normally these cumene radicals are converted to cumene hydroperoxide , however they can also undergo radical disproportionation to form AMS.
Purple-K, also known as PKP, is a dry-chemical fire suppression agent used in some dry chemical fire extinguishers. [1] It is the second most effective dry chemical in fighting class B (flammable liquid) fires after Monnex (potassium allophanate), and can be used against some energized electrical equipment fires (USA class C fires). [2]
It is similar to but not identical to dry chemical fire extinction methods, using an innovative pyrogenic, condensed aerosol fire suppressant. It is a highly effective fire suppression method for class A, B, C, E and F (as is the case for most fire-extinguishing agents, it is not applicable to metal fires – class D). [1]
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, 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 ...
Arctic Fire is a liquid fire extinguishing agent that emulsifies and cools heated materials more quickly than water or ordinary foam. It is used extensively in the steel industry. Effective on classes A, B, and D.

The creation of sparks from metals is based on the pyrophoricity of small metal particles, and pyrophoric alloys are made for this purpose. [2] Practical applications include the sparking mechanisms in lighters and various toys, using ferrocerium; starting fires without matches, using a firesteel; the flintlock mechanism in firearms; and spark testing ferrous metals.
