| Resumen |
One of the hazards associated with the use of CO2 in fire extinguishers is the production of very high electrical charges during release, which may ignite explosive mixtures if such are present. Measurements showed that small solid particles of CO2 are produced containing static electricity with voltages of 10-20 kV and potential spark energies easily capable of igniting the lower paraffins. Nitrogen is preferred to CO2 in fire-fighting systems since it does not produce solid particles when releasing the pressure and the amount of static electricity is less pronounced, but the use of solid CO2 generators is suggested as a safe way to replace air by a non-explosive mixture in a reaction vessel. |
