The disclosed invention relates to novel biocompatible firefighting foam compositions that include a deep eutectic solvent. Disclosed are methods of making and using firefighting foams containing deep eutectic solvents, which may also be used in existing fire foam compositions as drop in solvent additives. The deep eutectic solvents may also be used in or as a principle component of surrogate firefighting foam compositions.

Firefighting foam compositions containing deep eutectic solvents

A sprinkler includes an inlet aperture, an outlet aperture, a body, a conical member, and a deflector. The inlet aperture receives fire suppressant agent at an inlet end of the sprinkler and the outlet aperture is at an outlet end of the sprinkler. The body extends along a longitudinal axis and includes an inner volume forming a fluid flow path between the inlet end and the outlet end of the sprinkler. The conical member is positioned at the outlet end of the sprinkler directs the fire suppressant agent outwards. The deflector receives fire suppressant agent from the conical member and distributes the fire suppressant agent about a service area. The deflector includes multiple tines, which each extend along a corresponding radial axis that is substantially perpendicular with the longitudinal axis. Each tine is offset by an angular amount about the corresponding radial axis.

The present invention provides a fire extinguishing composition. The composition comprises monoammonium phosphate and potassium chloride. In one embodiment, the composition comprises a weight percentage of monoammonium phosphate in a range of between about 51% and about 99%, and a weight percentage of potassium chloride in a range of between about 1% and about 49%.

Fire foam concentrates are provided that contain trimethyl glycine as a freeze suppressant, an effective amount of at least one anionic, zwitterionic or nonionic surfactant, and an effective amount of a foam stabilizing agent. Methods of preparing fire fighting foams from the concentrates, and methods of fighting fires using these foams, also are provided.

A nozzle assembly for encapsulating a gaseous solution in bubbles comprises a discharge tube having a diffuser and a foam solution spray nozzle mounted therein. The discharge tube has upstream and downstream ends. The discharge tube has a front face at the upstream end with a first opening configured to be joined to a gas supply line that provides a gaseous solution and a second opening configured to receive a non-expanded foam solution. The downstream end of the discharge tube is open. A chamber is formed within the discharge tube to receive the gaseous solution at the upstream end and release the gaseous solution through the diffuser into the discharge tube towards the downstream end.
