BACKGROUND

Exemplary embodiments of the present disclosure pertain to the art of fire suppression agents.

Halon 1301 has frequently been employed as a fire suppression agent but there is currently a desire to replace Halon 1301 with more environmentally friendly fire suppression agents or blends of agents. CF3I has been suggested as an alternative but faces obstacles. Solutions are needed for environmentally friendly fire suppression agents which incorporate CF3I.

BRIEF DESCRIPTION

Disclosed is a fire suppression agent composition including CF3I and an additional fire suppression agent selected from the group consisting of HFC-23, HFC-125, HFC-227ea, dodecafluoro-2-methylpentan-3-one (Novec 1230), and HCFO-1233zd(E), wherein the fire suppression agent composition passes the FAA aerosol can test.

In addition to one or more of the features described above, or as an alternative to any of the foregoing embodiments, the fire suppression agent composition has a lower human toxicity than CF3I.

In addition to one or more of the features described above, or as an alternative to any of the foregoing embodiments, CF3I is present in an amount of 30 to 70 weight percent (wt %), based on the total weight of the fire suppression composition.

In addition to one or more of the features described above, or as an alternative to any of the foregoing embodiments, the additional fire suppression agent is present in an amount of 30 to 70 wt %, based on the total weight of the fire suppression composition.

In addition to one or more of the features described above, or as an alternative to any of the foregoing embodiments, the molar ratio of CF3I to the additional fire suppression agent is 0.4 to 1.5.

In addition to one or more of the features described above, or as an alternative to any of the foregoing embodiments, the additional fire suppression agent has a boiling point lower than CF3I. The difference between the boiling points is greater than or equal to 10° C. The difference between the boiling points is greater than or equal to 25° C.
