Here are some fire suppression chemical:

  • Carbon Dioxide (CO2): Carbon Dioxide is a time proven clean agent. Non conductive CO2 is particularly effective in confined areas, where there is a risk from flammable liquids, being non-toxic and leaving no residue CO2 will not harm food, fabrics, machinery or electrical equipment.
  • ABC Dry Chemical: It is a pale yellow powder that is able to put out all three classes of fire; Class A for trash, wood and paper, Class B for liquids and gases, and Class C for energized electrical sources.
  • Purple K (BC Dry Chemical): Purple-K is one of the most effective dry chemicals against Class B fires. It is a potassium bicarbonate-based material containing chemical additives.
  • Novec 1230: NOVEC 1230 does not remove or reduce Oxygen! NOVEC 1230 is a synthetic/chemical fire suppression gas and extinguishes a fire by removing the free radicals or heat elements from the fire triangle. Fire protection fluid is a next generation clean agent Halon alternative. It combines outstanding extinguishing performance with an excellent environmental profile.
  • FM200: 1,1,1,2,3,3,3-Heptafluoropropane, also called heptafluoropropane, HFC-227ea (ISO name), HFC-227 or FM200, as well as apaflurane (INN), is a colourless, odourless gaseous halocarbon commonly used as a gaseous fire suppression agent.
