Cellular glass system for suppression of vaporization, fire and thermal radiation from liquid hydrocarbons
A passive fire suppression system including at least one tapered cellular glass block and having a cap with a tapered shape disposed on the top of the at least one cellular glass block. The passive fire suppression system allows drainage from the upper surface to the bottom of the system. The drainage is beneficial for both environmental conditions such as rain as well as for incidents where combustible liquids are spilled on the top surface of the system. Therefore, the system will not only shield any combustible materials that are under the system but will also quickly drain any combustible liquids that may spill onto the top of the system to the lower surface.

at least two cellular glass blocks, wherein each of the cellular glass blocks comprises cellular glass having a lower density than that of the liquid hydrocarbon,
the at least two cellular glass blocks each having a top, a bottom, and a plurality of sides extending downwardly from the top, the top comprising at least two surfaces which slope from a midline having a first height downwardly to a second height;
wherein the at least two cellular glass blocks are interconnected by a self-draining connector bridge capable of draining the liquid hydrocarbon.
2. The system of claim 1 , further comprising a cap situated on the top of at least one of the cellular glass blocks.
3. The system of claim 2 , wherein the cap covers the surfaces of the top.
4. The system of claim 2 , where the cap covers more than one of the cellular glass blocks.
5. The system of claim 2 , further comprising a base disposed on the bottom of each of the cellular glass blocks.
6. The system of claim 5 , wherein the cap, the base, and the connector bridge are metallic.
7. The system of claim 1 , wherein the surfaces of the top slope downwardly from the first height to the connector at the second height.
8. A passive fire suppression system for use with a liquid hydrocarbon fuel, the system comprising:
a plurality of cellular glass blocks, each of the cellular glass blocks comprising cellular glass having a density less than the liquid hydrocarbon, each of the glass blocks having a top comprising at least two surfaces which slope from a midline having a first height downwardly to a second height;
a cap disposed on the top of at least one cellular glass block, covering the surfaces of the glass block;
a self-draining connector bridge positioned at the second height between adjacent caps, the connector bridge comprising at least one drainage hole.
9. The system of claim 8 , wherein the self-draining connector bridge comprises a plurality of drainage holes arranged in a substantially linear fashion along a line defined by two adjacent glass blocks.
10. The system of claim 8 , further comprising a base disposed on the bottom of each of the cellular glass blocks.
11. The system of claim 10 , further comprising at least one connector strip connecting the cap and the base.
12. The of claim 11 , wherein the cap, the base, and at least one connector strip are metallic.
13. The system of claim 8 , wherein the cap covers more than one of the cellular glass blocks.
14. A method of reducing the risk of fire, thermal radiation, and vaporization from a contained liquid hydrocarbons, the method comprising:
positioning a plurality of cellular glass blocks on the surface of the liquid hydrocarbon;

16. The method of claim 14 , wherein the plurality of cellular glass blocks are positioned such that the surface of the liquid hydrocarbon is covered.
17. The method of claim 14 , wherein the cellular glass blocks further comprise a base disposed on the bottom of the cellular glass block.
18. The method of claim 17 , wherein each of the cellular glass blocks further comprise a connector strip connecting the cap and the base of the cellular glass block.
