What are the four methods of fire extinguishment represented by the Fire Triangle and Fire Tetrahedron, and how does each method stop combustion?
Why is water considered the most common extinguishing agent in structural firefighting, and how do specific heat and latent heat of vaporization contribute to its effectiveness?
What are some of the advantages and disadvantages of using water as a suppression agent, particularly in structural fires?
Compare and contrast the primary extinguishing mechanisms of carbon dioxide (CO₂), Class A foam, and Class B foam.
Why are wet chemical agents used for Class K fires, and what is the role of saponification in extinguishing cooking oil and grease fires?
What types of fires are dry chemical, dry powder, and clean agents designed to extinguish, and what factors influence when each agent should be used?
