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.

1. FIRE SAFETY COURSE FEES:
Fire is a rapid chemical reaction
of oxidant with fuel accompanied
by the release of energy, indicated
by incandescence or flame.

2.  On the basis of the type of fuel, fires are
classified into the following
 Class A Fires — solid combustible materials
of organic nature such as wood, paper,
rubber, plastics, etc.
 Class B Fires — flammable liquids

3.  Type of extinguishers and the classes of fire
for which they can be used
 Water- Class A fire Dry
 chemical powder- Class B
 fire Foam- Class A & B
 fire Carbon dioxide- Class B & C
 fire Special dry powder- Class D fire

4.  • The extinguishing agent is aqueous film
forming concentrate in water which forms
air foams when discharged through
an aspirating nozzle.
• It has a blanketing effect excluding oxygen
from the surface of the fuel as it spreads on
the fuel.
• Prevents vapour formation from the surface
of the burning liquid
