In order to dam up leaking liquid chemicals or contaminated water after a fire within a building, effective and quickly operational gate seals are needed. These also serve as protection against penetrating surface water.
Internal works traffic and the general production process often do not allow permanent or constructional protective measures. The double-chamber hose, however, can be applied as a mobile protection device which in case of an emergency is installed within several minutes. Thanks to its specially inserted filling device, both hose chambers can be filled with water simultaneously.
