Freeze spray

Freeze spray (cold spray or vapocoolant) is a type of aerosol spray product containing a liquified gas used for rapidly cooling surfaces, in medical and industrial applications. It is usually sold in hand-held spray cans. It may consist of various substances, which produce different temperatures, depending on the application.

Some of them are highly flammable. Several other types of compressed gas sprays also have a freezing effect: for example, tetrafluoroethane, gas dusters, liquid nitrogen, and carbon dioxide fire extinguishers.
