Manage fire fighting with Fireblocker

The Fireblocker system will give fire fighters the opportunity to manage the fire within tunnels with a greater controllability.

Reduce fire area by blocking the tunnel

The idea is to block the tunnel from either side of the fire with a large balloon ( or a couple of balloons) mounted on a special vehicle. The balloon (or balloons) will be inflated partly with the non combustible gas Helium for sealing of the overhead structure and partly with air and will so sealing of and reducing the area where the fire exists.
These large balloons are being transported, in an un-inflated capacity, towards the fire on a bus type means of transport and being brought as close to the fire as possible without risking the inflatable devices or transport vehicle catching fire.

The material of which the inflatable balloons are made of exist of a high temperature resistant material and is resistant till approximately 1000 degrees centigrade.

Inflate and block

When the van type vehicle comes near the fire it will park in the middle of the tunnel releasing a large flow of gas into the balloons. After the balloons have fully expanded they will block the tunnel completely and the transport of oxygen towards the fire (together with other gasses) will be blocked.

Due to the fire, oxygen will be consumed in the fire area and this will decrease the oxygen percentage in the blocked area between two van type vehicles parked at each side of the fire.
