Fire suppression

01 Feb 2002

EUROTUNNEL is installing water mist fire suppression from Fogtec Brandschutz on seven HGV shuttle trains. Each vehicle is to be fitted with 30 Fogtec water nozzles, spaced at 1m intervals. Activated by infra-red sensors, the nozzles do not have moving parts, and are modular for ease of servicing.

Wind tunnel testing showed that Eurotunnel's fire suppression requirements could best be met with a water mist. Gas extinguishing could not be used because of the open structure of the shuttles, and the water needed by a conventional deluge system could not be carried on board.
