All fire extinguishing systems rely on breaking the fire triangle, which consists of three main elements:
1. Fuel, or flammable material, includes things like paper, fabric, and wood.
2. Heat, which is produced by converting energy into various forms.
3. Oxygen, which is present in the open air and contributes to the rate of reaction and the spread of fire.
One or more of the components of the fire is fought in one of the following methods when the three factors of ignition—a chemical reaction—are present
1. Cooling, or lowering body temperature
2. Suffocation (oxygen deficiency)
3. Insulation (obstructing the flammable substance)
Fire Blockers CO. has placed a high priority on this topic since it is essential to have a fire extinguishing system in both residential and non-residential constructions, especially given the rapid improvements in firefighting and extinguishing technology. Because of their large quantity, fire extinguishing systems are split into two primary categories:
The manual extinguishing system is effective in the first stage of the fire. It is a low-cost system that is easy to use for ordinary people, so it must be present in all residential and non-residential buildings. It is divided into two types:
It is a cylinder containing compressed chemical compounds that work to break the fire triangle. It has many types that differ according to the type of material used to extinguish the fire, the most famous of which are the powder extinguisher and the carbon dioxide gas extinguisher.
It is a metal box that is fixed to the wall. Inside it is a hose with a nozzle at one end and the other end is connected to a pump to pressurize the liquids using pipes that can withstand high pressure. It has several types, the most famous of which are those that work with water and foam.
With the development of technology, many systems have been invented to combat fires automatically without human intervention in operation to reduce the risks to lives and property. In general, this type of extinguishing system is considered expensive compared to other systems and is usually only installed in areas with a high degree of risk (High Risk) such as factories, workshops, warehouses, etc. In general, automatic extinguishing systems have been divided into two main sections, which are:
The wet fire extinguishing system depends on the use of water alone or with some chemical additives. The general form of the system is a network of pipes with sprinklers that have an explosive head at a certain temperature, and they are distributed in a geometric manner inside the building. The water is pressurized inside the pipe network by at least one pump that operates automatically as soon as the pressure inside the pipe network decreases.
In this system, clean gases are used to extinguish the fire, such as carbon dioxide and FM200. They are filled in compressed cylinders and connected to a network of pipes containing nozzles that distribute the compressed gas in a technical manner so that it covers all the area that needs to be protected. This system is usually used in areas that are damaged by the wet extinguishing system, such as engine rooms, important equipment, and archive rooms.
