The principles of fire prevention are essential to prevent fires. Fires can be started by a spark, strike a match, or obstruct machinery ventilation. Other causes include flammable materials being placed near heaters or air conditioners. Any combustible material, including wood, paper, oil, gasoline, and plastic, can burn. Fuel is needed for a fire to start and can be solid or liquid. While solid fuels must reach a critical temperature to ignite, many liquids release flammable vapors even when they are cold. Gases are the most dangerous combustible substances since they can ignite instantly, so they must be kept at a safe distance.

Heat
The principle of fire prevention is based on the concept that heat is required for a fire to start. All flammable materials produce flammable vapors when they burn. Heat is also necessary to spread a fire because it removes moisture from nearby fuel and pre-heats any fuel in its path. Heat can be obtained from the Sun, hot surfaces, sparks, friction, electrical energy, etc.
While some materials are not combustible, they are combustible. Fire spreads through conduction, which occurs when material comes in contact with fire. High temperatures pass through these materials and ignite the fuel source on the other side. A good example of this is metal. Metal doesn’t catch fire easily, but it can heat up to a high temperature and set on paper.
Oxygen
Fire is an explosive event requiring heat, fuel, and oxygen. While ambient air comprises mainly oxygen, most fires require only 16% of this to burn. Oxygen acts as an oxidizing agent, enabling the fuel to react with the oxygen to release heat and produce combustion. Fire prevention practices should minimize this risk while still meeting legal requirements.
A well-designed oxygen reduction system can effectively reduce the oxygen concentration in the air. The level of protection must be established and maintained by identifying and testing all substances in the area to be protected. Design concentrations are based on the lowest ignition threshold substance in the protected area. Group-related risks are defined in material configurations, which are known, and can be assigned a fixed design concentration. Oxygen reduction is possible without sacrificing protection from fire.
Fuel
Fuels are the principal sources of fire. These substances can burn readily in a normal atmosphere. Fuels can include wood, gasoline, diesel fuel, flammable gas, paper, and oil. Propane and butane are also flammable gasses. Most petroleum products have flammable vapors and can be controlled by proper housekeeping and operating procedures. Fuels should be stored in sealed containers at a safe distance from flammable materials or potential ignition sources.
It is essential to understand what fuels are and what type of fuel they are when preventing fire. All fuels need heat to ignite, and the heat generated will keep the fire burning. Heat will also spread fire, removing moisture from fuels nearby and pre-heating all fuels in its path. A fire will spread and consume as much fuel as there is, and there are three basic types of fuels.
Proper housekeeping
Performing good housekeeping at work will help you avoid injuries and accidents. In addition to preventing injuries, good housekeeping also improves productivity.
In addition to preventing injuries, good housekeeping is essential in fire prevention, and it can also prevent fires from spreading throughout your workplace. A good housekeeping program will keep walkways clear of clutter and trip hazards, promoting morale and ensuring that everyone can exit safely. Fire and smoke spread faster than most people realize, so preventing fires is critical. Fire prevention starts with the right attitude, proper housekeeping, and how to prevent them.
Steam
When used correctly, steam can reduce the chance of a fire reigniting. Steam creates a thermal buffer beneath the gases, inhibiting their interaction with oxygen. Overproduction of steam can also affect thermal balance and visibility and may impair firefighters’ PPE. It is important to remember that steam without fire gases is colorless. However, excessive steam production can affect the neutral plane, which is the layer of fresh air that firefighters must protect themselves from.
A firefighter must learn about the difference between water and steam because each is affected differently by the presence of heat. Because steam and water have different expansion ratios, it’s essential to understand how water can affect the flame and the structure that a fire is consuming. The International Society of Fire Service Instructors developed a guide to firefighting with water and steam. It also shows how the flow of water affects fire gases and the structure.
