This document provides an overview of fire safety training. It discusses the fire triangle and tetrahedron that represent how fire occurs. It outlines common causes of fires such as faulty wiring, smoking materials, and welding operations. The document describes different classes of fires from A to E and the appropriate extinguishers for each class. It demonstrates how to properly use a fire extinguisher with the PASS method of pull, aim, squeeze, and sweep. The goal of the training is to teach participants how to identify fire types, select the correct extinguisher, and safely fight early-stage fires.

• After this training you
should be able to:
• IDENTIFY common classes
of fires
• SELECT the proper type of
extinguisher
