What is the most commonly found halon in portable fire extinguishers?

The most commonly found halon in portable fire extinguishers is Halon 1211. This compound is widely utilized due to its effectiveness in extinguishing fires involving flammable liquids and electrical equipment without causing additional damage. Halon 1211 is a brominated fluorocarbon that works by interrupting the chemical reaction in the fire, making it suitable for Class B (flammable liquids) and Class C (electrical) fires. Its ability to suppress flames without leaving residue is a significant advantage, especially in environments with sensitive electronic equipment.

Other halons listed, such as 1301, are typically used in fixed installations rather than portable extinguishers. Halon 2402 and Halon 3000 serve specific applications and are not as prevalent in portable fire suppression systems as Halon 1211. Therefore, the choice of Halon 1211 reflects its widespread acceptance and use in portable fire extinguishers designed to handle various fire scenarios.
