Carbon dioxide fire extinguishers build up significant static electricity charges during use. The shock from the resulting discharge can startle the operator and has ignited explosions in certain cases. The cause of the electrostatic buildup is attributed to the plastic horn used as a spray nozzle. Researchers at the Naval Research Laboratory have developed a new horn arrangement which consists of a metal sleeve inserted snugly inside the plastic horn. The metal sleeve reduces the electrostatic buildup while maintaining electrical insulation and insulation from the cold temperatures caused during CO2 discharge.
