a second hose mounted external to the first hose along an entire length of the first hose for transporting pressurized gas; and
a plurality of quick release connectors coupled to respective exit points along the second hose and spaced apart at predetermined intervals substantially along an entire length of the first hose incident to a zone of fire, wherein the firefighter is able to connect to any one of the plurality of quick release connectors for receiving the pressurized gas from the second hose at sufficient pressure to fill the portable pressurized tank without leaving the zone of fire.
2. The firefighting system of claim 1 , further including a sheath to encase the first hose and the second hose.
3. The firefighting system of claim 2 , wherein the sheath is made of non-flammable material.
4. The firefighting system of claim 2 , wherein the sheath made of rubber.
5. The firefighting system of claim 1 , further including a third hose for coupling the portable pressurized tank to the second hose.
6. The firefighting system of claim 1 , further including a transceiver electrically coupled to the plurality of quick release connectors for receiving a connector-dependent signal activated by connecting the portable pressurized tank to one of the plurality of quick release connectors, wherein the connector-dependent signal indicates the one of the plurality of quick release connectors to which the portable pressurized tank is connected.
7. The firefighting system of claim 1 , wherein each of the plurality of quick release connectors further include a plurality of independent stations, the firefighter being able to connect to any one of the plurality of independent stations.
8. A firefighting system for filling portable pressurized tanks used for life support while fighting a fire, comprising:
a first hose for transporting a firefighting compound;
a conduit for transporting pressurized gas; and
a plurality of connectors coupled to exit points along the conduit and spaced apart substantially along a length of the first hose, wherein the portable pressurized tank is connectable to each one of the plurality of connectors for receiving the pressurized gas from the conduit at sufficient pressure to fill the portable pressurized tank.
9. The firefighting system of claim 8 , wherein the plurality of connectors further include a quick release mechanism to allow the portable pressurized tank to quickly disconnect from the conduit.
10. The firefighting system of claim 8 , further including a sheath to encase the first hose and the second hose.
11. The firefighting system of claim 10 , wherein the sheath is made of non-flammable material.
12. The firefighting system of claim 8 , wherein each of the plurality of connectors further include a plurality of independent stations, a firefighter being able to connect to one of the plurality of independent stations.
13. The firefighting system of claim 8 , further including a third hose which is adapted to couple the portable pressurized tank to the conduit.
14. In a firefighting system, a firefighter using a portable pressurized tank for life support while fighting a fire, comprising:
a first hose for transporting a firefighting compound;
a second hose disposed along an entire length of the first hose for transporting pressurized gas;
a plurality of connectors coupled to exit points spaced apart along the second hose, wherein the firefighter is able to connect the portable pressurized tank to one of the plurality of connectors; and
a transceiver electrically coupled to the plurality of connectors for receiving a connector dependent signal activated by connecting the portable pressurized tank to one of the plurality of connectors, wherein the connector-dependent signal indicates the one of the plurality of connectors to which the portable pressurized tank is connected.
15. The firefighting system of claim 14 , further including a sheath to encase the first hose and the second hose.
16. The firefighting system of claim 14 , wherein the plurality of connectors further include a quick release mechanism to allow the portable pressurized tank to quickly disconnect from the second hose.
17. The firefighting system of claim 14 , wherein each of the plurality of connectors further include a plurality of independent stations, the firefighter being able to connect to any one of the plurality of independent stations.
18. The firefighting system of claim 14 , further including a third hose which is adapted to couple the portable pressurized tank to the second hose.
19. A method of making a firefighting system for use in filling portable pressurized tanks, comprising:
providing a first hose for transporting a firefighting compound;
providing a second hose mounted external to the first hose along an entire length of the first hose for transporting pressurized gas; and
providing a plurality of quick release connectors coupled to exit points along the second hose and spaced apart at predetermined intervals substantially along an entire length of the first hose, wherein the portable pressurized tanks are connectable to each one of the plurality of quick release connectors for receiving the pressurized gas from the second hose at sufficient pressure to fill the portable pressurized tank.
20. The method of claim 19 , further including providing a sheath to encase the first and the second hose.
21. The method of claim 19 , further including providing a third hose which is adapted to couple the portable pressurized tank to the second hose.
