Fire prevention - stationary fire protection systems based on carbon dioxide (CO2)

One of the very effective fire protection systems in woodworking industry, besides the sprinkler system, is the stationary fire extinguisher with carbon dioxide (CO2). Carbon dioxide extinguishes the fire by forcing out oxygen which is necessary for combustion. The quantity of CO2, needed for extinguishing depends on the room size and amounts from 0,70 to 1 kg/m3, and for local protection to 3 kg/m3. For surface protection it is required even up to 8 kg/m3. The pipe-lines serve for transportation of CO2 from containers to the building. Nozzles are used for directing and forming of the jet. System with CO2 is activated by automatic fire alarms. If such protected room is foreseen for people to stay in, the system must be equipped with an alarm contrivance and a »time delay« device, warning those present to leave the place within 30 seconds and then activating the container with carbon dioxide which extinguishes the fire.
