This document discusses fire safety courses and fees. It classifies fires into different classes based on the type of fuel. Class A fires involve solid organic materials, Class B involve flammable liquids, and Class C involve energized electrical equipment. It lists the types of fire extinguishers that can be used for each class, such as water, dry chemical powder, foam, and carbon dioxide. The document also provides information on how foam acts as an extinguishing agent by forming an air foam with a blanketing effect to prevent oxygen and vapour formation at the fuel surface. It concludes with contact information for the National Safety Academy branch offering fire safety courses.
