The Smokin' Science of Fire Extinguishers

The video tutorial explains the chemistry of fires and the fire tetrahedron, which consists of oxygen, fuel, heat, and a chemical chain reaction. It discusses different fire classes (A, B, C, D, K) and the appropriate extinguishers for each. Class A fires involve common materials, Class B fires involve flammable liquids or gases, Class C fires involve electrical equipment, Class D fires involve combustible metals, and Class K fires involve cooking oils. The video emphasizes the importance of using the correct extinguisher to prevent spreading the fire or causing harm.

What are the four elements that make up the fire tetrahedron?

Explain why water is not always effective in extinguishing class B fires.

What distinguishes class D fires from other types of fires?

Describe the function of class K fire extinguishers and where they are typically used.

What mnemonic can help remember the different classes of fires?
