Basics principles on which fire extinguishers works: -Smouldering: It involves removal of oxygen or decreasing presence of oxygen. - Cooling: It involves the process of reducing heat or removal of heat. -Starvation: It involves the removal of fuel from the scene of fire .
During a fire, there is a constant supply of oxygen as it diffuses from the surrounding air. The amount of oxygen present can influence the rate and intensity of the flame. To extinguish a fire, you can remove the oxygen supply by smothering the flame with an agent that blocks out the oxygen supply.
Oxygen, heat, and fuel are frequently referred to as the "fire triangle." Add in the fourth element, the chemical reaction, and you actually have a fire "tetrahedron." The important thing to remember is: take any of these four things away, and you will not have a fire or the fire will be extinguished.
Fire requires fuel, heat and oxygen to burn. Fire extinguishers apply an agent that will cool burning heat, smother fuel or remove oxygen so the fire cannot continue to burn. A portable fire extinguisher can quickly control a small fire if applied by an individual properly trained.
A fire needs three elements - heat, oxygen and fuel. Without heat, oxygen and fuel a fire will not start or spread. A key strategy to prevent fire is to remove one or more of heat, oxygen or fuel.

Financial Independence, Retire Early (FIRE) is a financial movement defined by frugality, extreme savings, and investment. FIRE proponents may start by calculating their FIRE number, generally 25 times their annual expenses, which is the amount of money they expect to need in order to retire comfortably.
It's easy to remember how to use a fire extinguisher if you can remember the acronym PASS, which stands for Pull, Aim, Squeeze, and Sweep. Pull the pin. This will allow you to discharge the extinguisher.
The theory of fire extinguishment is based on removing any one or more of the four elements in the fire tetrahedron to suppress the fire. In order to remove the heat, something must be applied to the fire to absorb the heat or act as a heat exchanger.
There is a golden rule when it comes to fires and the use of fire extinguishers, and that is: If in doubt, get out. That essentially means, if you're considering whether you'd be able to tackle a fire confidently and successfully with an extinguisher and you have any doubts, simply evacuate.
In order to extinguish a fire, one of the three elements of the fire triangle must be eliminated. This is due to the fact that a fire cannot begin or continue when there is zero or insufficient heat, fuel, or oxygen.
Fire safety signs are designed to let occupants of a building know what to do in the event of a fire. They can pinpoint fire safety equipment and warn staff of potential fire hazards.
Understanding the three P's of fire safety – prevention, protection, and preparation – can help you keep your property and loved ones safe from the devastating effects of fire. In this article, I will explore the importance of each P and provide tips on how you can implement them in your daily life.
The letter on a fire extinguisher indicates its classification: Class A puts out ordinary combustible fires (wood, paper, plastic, etc.) Class B puts out flammable liquid fires (oil, gas, petroleum, etc.) Class C puts out electrical fires.
The majority of fire-related deaths are caused by smoke inhalation of the toxic gases produced by fires.
They work by smothering the fire: when you put a layer of powder or foam on the fire, you cut the fuel off from the oxygen around it, and the fire goes out.
The employer shall provide portable fire extinguishers and shall mount, locate and identify them so that they are readily accessible to employees without subjecting the employees to possible injury. Only approved portable fire extinguishers shall be used to meet the requirements of this section.
The 3 things a fire needs are heat, fuel and oxygen. These three elements work together to help a fire start and take over. However, if any of the three elements are removed from a fire, then it will extinguish and no longer pose a threat.
Nobody should put themselves in danger to fight a fire and it is important that anyone attempting to fight a fire knows how to use the equipment and has a clear exit route available. The golden rule is that only one extinguisher is used. If that fails to extinguish the fire, STOP and leave.
The 4% rule refers to the idea that, once this money is saved, you should aim to withdraw 4% of your savings per year during retirement.
It is easy to remember how to use a fire extinguisher if you can remember the acronym PASS, which stands for PULL, AIM, SQUEEZE, and SWEEP. Pull the pin. This will allow you to discharge the fire extinguisher.
