Fog nozzles can be used with foam solution to produce what?

Fog nozzles can be used with a foam solution to produce low expansion foam. This type of foam is characterized by a lower air content and is primarily used for blanket coverage and extinguishing classes of fires involving flammable liquids.

When a foam solution is introduced to a fog nozzle, the nozzle creates a fine mist of water and foam concentrate, which allows for the rapid spread of the foam across the burning surface. Low expansion foam provides a layer that smothers the fire, cooling the heat and suppressing vapors, thus effectively controlling or extinguishing fires.

The other foam types, such as high expansion foam, require different application techniques and equipment, typically involving specialized generators to produce large quantities of foam and air mixture. Medium expansion foam also has a different composition and application method that is more suitable for certain types of fires, but is not the product produced with a fog nozzle. Wet foam may refer to foam that retains more water content, which is also not the outcome specifically achieved with the use of a fog nozzle.

Thus, using a fog nozzle with foam solution is specifically effective in generating low expansion foam, ideal for tackling various flammable liquid fires.
