Can milk put out a fire?
Milk and Grease Fires Some experts say milk also can cause a fireball or explosion when put on a grease fire. The only way milk can put out a grease fire is if such a vast quantity of milk is used that it completely submerges the fire, causing the fire to run out of oxygen.
What are 3 elements of fire?
Oxygen, heat, and fuel are frequently referred to as the “fire triangle.” Add in the fourth element, the chemical reaction, and you actually have a fire “tetrahedron.” The important thing to remember is: take any of these four things away, and you will not have a fire or the fire will be extinguished.

What is tetrahedron of fire?
the fire tetrahedron is a four-sided geometric representation of the four factors necessary for fire: fuel (any substance that can undergo combustion), heat (heat energy sufficient to release vapor from the fuel and cause ignition), oxidizing agent (air containing oxygen), and uninhibited chemical chain reaction ( …
What is a Class D fire?

What kind of fire is a Type A fire?
“A” TRASH–WOOD–PAPER Fire extinguishers with a Class A rating are effective against fires involving paper, wood, textiles, and plastics. The primary chemical used to fight these fires is monoammonium phosphate, because of its ability to smother fires in these types of materials.
What are the 5 types of fire?
