Abstract
1306734 Fire fighting with CO 2 DEFENCE SECRETARY OF STATE FOR 24 June 1971 [15 July 1970] 34242/70 Heading A5A A method of fire fighting wherein the electrostatic charge produced on release of the suppressant is reduced comprises releasing a finely divided mixture of a solidified inert gas and a liquid which has electrical resistivity not greater than 1000 ohm cm and freezes between 200 and 250‹K. The inert gas may be CO 2 , and the liquid may be water containing methanol Œ ethylene glycol, and/or NaCl or CaCl 2 , in an amount less than 10% by wt. Apparatus may comprise CO 2 cylinder 2 connected via valve 4 to horn 8, and reservoir 10 of water + anti-freeze 12 releasably fastened at 14 to 2 and connected to horn 8 via pipe 16. When valve 4 is opened the CO 2 draws liquid from 10 and the mixture discharges as finely divided liquid particles entrained in solidified CO 2 .
