Fire - The construction and operation The construction and operation of modern fire extinguishers
Modern portable fire extinguishers are usually stored under pressure or Cartridge Operated Extinguishers. Manufacturers of fire extinguishers tend to produce two types of extinguishers stored pressure fire extinguishers are the most common.
Construction materials fire extinguisher.
Typically extinguisher modern organizations are constructed from steel, aluminum or aluminum alloy. These materials provide a fire extinguisher outside durable to withstand the blows, the outside temperature and corrosion. The toner cartridge operated extinguishers gas is usually covered with plastic cartridge to give additional protection against the contents of the extinguisher. There are two types of gas cartridges are in the modern fire extinguishers, are but disk cartridge piercing and seed failure. The disk cartridge piercing gas has a diaphragm which is pierced with a pin adapted form. The cartridge seed out of gas has a pip is broken by a dull time. In a gas cartridge extinguishers used only the cartridge itself is under pressure as a pressure extinguisher standing the whole body of the extinguisher is pressurized.
How different fire extinguishers work.
Stored pressure fire extinguishers work as follows: -
1. The fire extinguisher is operated by releasing the ankle, breaking the tamper seal and pressing the extinguisher handle.
2. The pressure stored in the top of the extinguisher (dry air or nitrogen) is released.
3. The forces of downward pressure on the extinguishing agent in fire extinguishers (water, foam, powder, etc.)
4. The extinguishing agent is forced into the trap of fire extinguisher, the pipe plug on the head and fire.
5. Some pipes are equipped with a fire extinguisher control squeeze the handle to regulate the flow of the extinguisher.
Fire extinguishers gas cartridge work as follows: -
1. The fire extinguisher is operated by releasing the ankle, breaking the tamper seal and pressing the extinguisher handle.
2. The action of pressing the extinguisher handle pushes a rod down on the seal of the cartridge.
3. The axis pierces the seal on the cartridge and release the pressure in the gas cartridge.
4. The pressure in the extinguishing of the gas cartridge and down on the forces of the extinguisher.
5. The extinguisher is then forced the siphon hose from the filler cap on his head and fire.
Sprinklers are commonly available on the market and are the type of fire extinguisher that people see most often while going about their daily business. Sprinklers are available in a variety of sizes, with 6 and 9 liter version being the most popular.
Foam extinguishers are also widely available on the market today. There are generally two types of foam extinguishers available. These are AFFF, FP, FFFP, AR, and EF, with the variant AFFF is the most commonly used.
Powder extinguishers are located in a variety of modern buildings. The fire extinguisher powder found most often is the dry powder ABC extinguisher. This type of extinguisher is again available in a variety of sizes and fire resistance with 6 kg and 9 kg being the most common.
Carbon dioxide extinguishers are not so common as water and foam extinguishers, but they have their particular areas where they are very effective. They are frequently observed in the 2 kg and 5 kg versions and are often seen near electrical equipment.
