Wet chemical fire extinguishers, marked by oatmeal colored band, are effective against fires involving cooking oils and fats.
They employ an agent that reacts with burning cooking oil or fat to form a suds-like blanket across the fuel surface, cutting off the fire’s air supply and preventing the release of flammable vapors.
Wet chemical fire extinguishers are suitable for the following types of fires:
Class a – paper, textiles, wood, most plastics and rubber
Class f – cooking oils or fat
