It explains the three components needed for a fire, different classes of fires, types of fire extinguishers and their uses, and the P.A.S.S. method for using an extinguisher. Key safety tips include only fighting small, incipient fires if you have the proper equipment, and evacuating the building immediately if the fire spreads or your instincts say to get out.
