This document discusses different types of fire extinguishers and their uses. It explains that there are four elements required for fire - oxygen, heat, fuel and a chemical reaction. It describes various fire extinguishers like water, foam, dry powder, and carbon dioxide, indicating what types of fires each can be used on. The document also discusses fire control methods, fire protection methods, and common fire control equipment like fire extinguishers, hydrants, smoke/heat detectors, fire alarms, sprinklers and blankets.

The document provides information on fire extinguishers, including their types, classifications of fires, and how to use them. It discusses water, carbon dioxide, dry chemical, wet chemical, and combustible metal extinguishers. The fire tetrahedron and combustion process are also explained. Fires are classified as Class A, B, C, D or K based on the type of fuel. Proper use of an extinguisher requires following the PASS method of pulling the pin, aiming at the base of the fire, squeezing the handle, and sweeping side to side. Safety procedures like RACE and knowing department emergency plans are also outlined.

This document provides training on fire safety, including how fires start by requiring fuel, oxygen, and heat; the four classes of fires; how to prevent fires; when not to fight a fire; how to use a fire extinguisher using the PASS method of Pull, Aim, Squeeze, Sweep; what to do after using an extinguisher; how to evacuate a burning building; and what to do if a person is on fire by having them stop, drop and roll. The overall goal is to describe fire safety and prevention, proper use of extinguishers, and emergency procedures.

Fire requires oxygen, heat, and fuel to burn in a process called the fire triangle. Fires can be classified based on the type of material burning, such as class A for non-metals, class B for flammables, and class C for gases. Proper fire prevention involves identifying ignition sources and fuels, fireproofing structures, installing alarms, and training occupants. In the event of a fire, it is important to remember RACE - rescue people in danger, alert others and emergency services, contain the fire, and evacuate safely.

Fire requires three elements: a fuel source, oxygen, and heat. Fire extinguishers work by eliminating one of these elements. There are four fire classifications - Class A for ordinary combustibles, Class B for liquids, Class C for electrical equipment, and Class D for chemicals. Different types of fire extinguishers use various pressurized agents like water, dry chemical, or carbon dioxide to put out different fire classes - water for Class A, dry chemical for Classes A, B, and C, and carbon dioxide for Classes B and C. Proper selection depends on the extinguishing agent and location.

This document provides information on fire safety and the use of fire extinguishers. It discusses the combustion process and fire classes A through K. It then describes the different types of portable fire extinguishers - pressurized water, carbon dioxide, and multipurpose dry chemical - and how they work to extinguish fires through cooling, smothering, or interrupting the chemical reaction. Guidelines are given for responding to a fire emergency using the R.A.C.E. method of rescue, alarm, contain, extinguish, as well as operating a fire extinguisher safely using the P.A.S.S. technique of pull, aim, squeeze, sweep.

This document provides information on fire sensors and fire detection systems. It discusses the causes and types of fires, and classifies them into 6 main categories (A-F). It then explains the different types of fire extinguishers and how they work by removing elements from the fire tetrahedron like oxygen, heat or fuel. The document outlines the basic components of a fire alarm system including inputs like manual pull stations and smoke detectors, as well as outputs like horns and strobes. It describes the stages of a fire and the different types of detectors used, such as photoelectric, ionization and heat detectors. Finally, it provides a practical example of a fire suppression system animation video.
