A method of extinguishing fires in glove boxes and hoods with carbon dioxide either automatically or manually before absolute filters could be clogged presents a safety feature for the chemist in plutonium-research laboratories. The automatic carbon dioxide release is electrically controlled through a rate- compensated electric heat detector that reacts to a temperature of 160 deg F. The heat detector releases electrically the carbon dioxide to a sealed nozzle where gaseous carbon dioxide forms as it flows through an orifice to completely fill the enclosure 15 seconds after discharge and continually flows for a minimum of 2 minutes. The liquid carbon dioxide discharged activates a pressure sensitive switch; this notifies the Fire Protection Department, sounds an alarm bell, and lights a neon lamp at the enclosure annunciator box.
