THE MANEUVER INVOLVES USING A LARGE, DURABLE TARP TO COVER A COMPRESSED LIQUEFIED GAS TANK THAT IS RELEASING ITS CONTENTS. BY DAVID F. PETERSON, CHMM Incidents involving gases or matter in the gaseous state cause the most problems for responders. This is because gas can travel where it wants and presents an inhalation exposure problem (especially if it is toxic or irritating) and because a gas and air mixture can ignite if the gas is flammable. These inherent problems are compounded if the gas is also compressed into a liquid and stored in a pressurized tank. The gas will exit the tank under pressure in a release, and the escaping gas will present a cold temperature or thermal hazard. Responders may use numerous methods to handle compressed liquefied gas (CLG) releases (e.g., cold patches, hot tapping, off-loading to another container); the Triple-T Maneuver is one of them. GAS BEHAVIORFirst, however,…
