Fire Suppression and Explosion Protection
Fire suppression and explosion protection have used halons in many applications because they are electrically non-conductive, dissipate rapidly without residue, are safe for limited human exposure, and are extremely efficient in extinguishing most types of fires. Because of their strong ozone depletion potential, the Montreal Protocol required the earliest production and import phaseout of halons in the U.S. in 1994.
- Total Flooding Agents are where a specific concentration of extinguishing agent is achieved in an enclosed area by discharge of an automatic system. SNAP has approved alternatives for halon 1301.
- Streaming Applications are where and extinguishing agent is directed to a fire using portable fire extinguishers. SNAP has approved alternatives for halon 1211.
