Abstract

A fire suppressant mixture comprising: an organic or supplemental organic fire suppressant compound having a boiling point; and an organic compound with a boiling point lower than the boiling point of the organic fire suppressant compound, wherein the organic fire suppressant compound and the organic compound are combined such that a boiling point of the mixture is lower than the boiling point of the organic fire suppressant. In some embodiments, the organic fire suppressant compound is FK 5-1-12 and the organic compound is carbon dioxide. In other embodiments, the mixture is supplemented with an additional organic compound CF 3 I and an inorganic pressurizing gas, such as nitrogen.

Claims (22)

1. A fire suppressant mixture consisting essentially of:

an organic fire suppressant selected from the group consisting of FK 5-1-12 and CF 3 I carbon dioxide; and,

a pressurizing gas selected from the group consisting of nitrogen, argon and helium;

wherein enough carbon dioxide is present in the fire suppressant mixture such that a normal boiling point of the fire suppressant mixture is at least 40 degrees Celsius lower than a normal boiling point of the organic fire suppressant.

2. The fire suppressant mixture of claim 1 , wherein the organic fire suppressant-is FK 5-1-12.

3. The fire suppressant mixture of claim 1 , wherein the pressurizing gas is nitrogen.

4. The fire suppressant mixture of claim 1 , wherein the mass ratio of the organic fire suppressant to carbon dioxide is approximately 4 to 1.

5. The fire suppressant mixture of claim 1 , wherein the organic fire suppressant is CF 3 I.

6. The fire suppressant mixture of claim 2 , wherein the organic fire suppressant compound is a mixture of both FK 5-1-12 and CF 3 I.

7. The fire suppressant mixture of claim 6 , wherein the organic fire suppressant and the carbon dioxide have a weight ratio of about 4 to 1, respectively, to about 5 to 1, respectively.

8. The fire suppressant mixture of claim 1 , wherein the normal boiling point of the fire suppressant mixture is between 40 and 75 degrees Celsius lower than the normal boiling point of the organic fire suppressant.

9. The fire suppressant mixture of claim 1 , wherein the normal boiling point of the fire suppressant mixture is at least 75 degrees Celsius lower than the normal boiling point of the organic fire suppressant.

10. The fire suppressant mixture of claim 1 , wherein the normal boiling point of the fire suppressant mixture is between 75 and 100 degrees Celsius lower than the normal boiling point of the organic fire suppressant.

11. The fire suppressant mixture of claim 1 , wherein the organic fire suppressant and the carbon dioxide have a weight ratio of about 4 to 1, respectively, to about 5 to 1, respectively.

12. A fire suppressant mixture consisting essentially of:

FK 5-1-12;

carbon dioxide; and,

a pressurizing gas other than carbon dioxide;

wherein enough carbon dioxide is present in the fire suppressant mixture such that a normal boiling point of the fire suppressant mixture is at least 75 degrees Celsius lower than a normal boiling point of FK 5-1-12.

13. The first suppressant mixture of claim 12 , wherein the pressurizing gas is selected from the group consisting of nitrogen, argon and helium.

14. The fire suppressant mixture of claim 13 , wherein the normal boiling point of the fire suppressant mixture is between 75 and 100 degrees Celsius lower than the normal boiling point of FK 5-1-12.

15. The fire suppressant mixture of claim 12 , wherein the pressurizing gas is nitrogen.
