FALCON’s Carbon Dioxide Fire Extinguisher is a colourless, odourless gas. A high pressure discharge of the gas provides a very fast fire fighting action, making it effective against class B fires involving electrical fires. Being heavier than air, it works by smothering the flames and reducing the oxygen content of the air around the fire. After use, CO2 disperses without leaving any contamination or corrosive residue and will not damage clothing, equipment or material.
