Injury may result if any part of your skin not covered by the liquid solution is allowed to come into contact with the fire. For maximum protection, consider wearing rubber laboratory gloves when lighting your hands.
What is class F fire?
Class F fires are fires which involve cooking oil or fat. Though technically a sub-class of fires caused by flammable liquids or gases, they differ from conventional fires due to the extremely high temperatures involved.
What is Type D fire?

What is a CO2 fire extinguisher?
CO2s are designed for Class B and C. (flammable liquid and electrical) fires only. Carbon dioxide extinguishes work by displacing oxygen, or taking away the oxygen element of the fire triangle. The carbon dioxide is also very cold as it comes out of the extinguisher, so it cools the fuel as well.
What type of fire extinguisher is CO2?
CARBON DIOXIDE (CO2)
They were originally designed for use on flammable liquid fires and therefore have a class B fire rating. They can be used on electrical fires, as CO2 is not a conductor and they do not leave behind any harmful residue.

What type of fire is K?
What Are Class K Fires? A Class K fire is fueled by flammable cooking liquids, such as cooking oil, and animal or vegetable-based greases. These liquids, when brought up to high temperatures, become volatile and can easily ignite. Due to their high flammability, they also spread rapidly.
