Title Fire hazard from electrostatic charging of carbon dioxide
Original title Zündgefahren durch elektrostatische Aufladung von Kohlendioxid [in German]
Bibliographic information 1982, Vol.34, No.7, p.393-393. 13 ref.
Abstract Many accidents involving tanks can be attributed to ignition of explosive gas/air mixtures by discharge of electrostatically charged carbon dioxide, which is used for fire extinguishing or displacement of explosive atmospheres. Laboratory experiments demonstrated the electrostatic charging of carbon dioxide at the outlet of a tank of compressed gas. The electric charge can vary from 0.01 to 30µC/kg, depending on the way the gas expands and on the shape of the outlet. Thus, CO2 tanks and installations should be earthed if they are to be used in the presence of explosive mixtures. Dry ice would be a safe means of displacing explosive gases and mixtures.
