There is an old saying about fire. It goes that whilst fire is a great servant it is a terrible master. What this basically means is that when we have it under control like in a fireplace, on a barbeque or a gas hobĀ  then it is fine. However, if it is allowed to burn wild and free it is ridiculous destructive and dangerous. A recent example of this is the wildfires experienced in Australia. This is why offices and the home should have a regular Fire Risk Assessment Bristol and surrounding areas, provided by the company in the link.

Fire is started in simple principles. You need three elements which is known as the fire triangle. The first is a source of heat. This can be from a spark, a naked flame, a cigarette or the sun’s magnified rays.

The second element is there needs to be a fuel to act as a source to keep the heat going. Flammable material comes in all shapes and sizes be it wood, oil or paper.

The third element is something that is in the atmosphere and the fuel. It is oxygen. This feeds the heat and allows it to expand to get to more of the fuel.

The way to stop the fire is to remove any of these elements. For example, water will cool the heat element. A foam or powder will remove the oxygen.
