Device for Distribution of Fire Suppressant
A device for protecting a lineman or firefighter from an electrical fire that occurs while working within a manhole. The device dispenses a non-conductive amount of fire suppressant material having fire suppression and extinguishing properties without creating an electrically conductive environment. The admixture preferably can cling to walls, ladders, clothing and skin.
1 . A device for suppressing a manhole electrical fire comprising:
a container;
an admixture of non-conductive fire suppressant stored within said container;
a distribution structure fluidly coupled to said container, said distribution structure having at least one spray nozzle juxtapositioned to a manhole opening; and
an activation means positioned between said container and said distribution structure, said activation means for use in releasing said stored admixture into said nozzle for dispensing through said manhole opening.
2 . The device for suppressing a manhole electrical fire according to claim 1 wherein said distribution structure is a ring shaped member constructed and arranged for placement along an edge of an open manhole.
3 . The device for suppressing a manhole electrical fire according to claim 2 wherein said distribution structure includes a plurality of spray nozzles having a directional spray pattern into the manhole opening.
4 . The device for suppressing a manhole electrical fire according to claim 3 wherein said spray nozzles provide overlapping spray patterns of said admixture.
5 . The device for suppressing a manhole electrical fire according to claim 1 wherein said nozzle rotates for distribution of said admixture of non-conductive fire suppressant.
6 . The device for suppressing a manhole electrical fire according to claim 1 wherein said container is coupled to said distribution structure by a flexible hose.
7 . The device for suppressing a manhole electrical fire according to claim 1 wherein said activation means is a manually operated valve.
8 . The device for suppressing a manhole electrical fire according to claim 1 wherein said activation means is a battery operated solenoid.
9 . The device for suppressing a manhole electrical fire according to claim 8 including at least one remote trigger electrically coupled to said solenoid.
10 . The device for suppressing a manhole electrical fire according to claim 9 wherein said remote trigger is wireless.
11 . The device for suppressing a manhole electrical fire according to claim 1 wherein said admixture is effective in reducing airborne organic compounds and airborne metals when added to an active arc fault.
12 . The device for suppressing a manhole electrical fire according to claim 1 wherein said storage container is pressurized with a compressed gas.
13 . A device for suppressing a manhole electrical fire comprising:
a container pressurized with a compressed gas;
an admixture of non-conductive fire suppressant stored within said container;
a distribution ring fluidly coupled to said container sized for placement about a manhold opening, said distribution ring having at least one spray nozzle directed into the manhole opening; and
a battery operated solenoid valve positioned between said container and said distribution ring, said solenoid for use in releasing said stored admixture into said nozzle for dispensing through said manhole opening upon activation.
14 . The device for suppressing a manhole electrical fire according to claim 13 wherein said distribution ring includes a plurality of spray nozzles having a directional spray pattern into the manhole opening.
15 . The device for suppressing a manhole electrical fire according to claim 13 wherein said container is coupled to said distribution structure by a flexible hose.
16 . The device for suppressing a manhole electrical fire according to claim 13 including at least one remote trigger electrically coupled to said solenoid.
17 . The device for suppressing a manhole electrical fire according to claim 16 wherein said remote trigger is wireless.
