The 'Combustion Triangle' or 'Fire Triangle' is a simple model illustrating that in order for fire to exist, three elements are required - Oxygen, Heat and Fuel. It therefore means in order to prevent or extinguish a fire, removing any one of these components would do it.
When these three elements are combined at the right mixtures, a fire will naturally occur. However, a fire can be prevented from igniting or a fire that is already burning extinguished by removing any single one of these elements:
Passive Fire Protection attempts to contain fires and limit/slow their spread throughout a building, through use of devices such as fire resistant walls, doors and floors. Unlike with active fire protection, passive fire protection systems do not require turning on, or power, gas or water to operate. They are always 'on' (cannot be turned 'off') and are inherent to the structure of a building. In the event of a fire, passive fire protection systems can contain the spread of both fire and smoke.
Typical passive fire protection products include intumescent sprays and paints, for example Nullifire and Thermoguard, and fire boards, for example Flamebreaker and Lafarge, which when combined together can provide a passive fire protective system. The fire protective qualities of these systems are tested according to three key criteria:
A Durasteel fire protection system independently meets all of these criteria by combining lightness, strength, impact, blast resistance and durability with exceptional fire resistance in one product.
Durasteel systems are installed all across the world providing premier passive fire protection in many diverse areas, including airports, distribution and storage warehouses, power stations, petrochemical plants, tunnels and rail stations.
Active Fire Protection devices and systems are reactive and require a certain amount of motion and response in order to work. This type of fire protection is installed additionally to the structure of a building. There are two types of active fire protection:
