Fire extinguishers use various products for extinguishing fires. When selecting your extinguisher, you need to determine what type of fire maybe you are fighting and then select the very best extinguishing product for your application. Water: Water, or APW, extinguishers use pressurized water to extinguish fires. APW extinguishers can only be used for Type A shoots (combustibles such as report, fabric, etc.); they cannot be useful for getting out other lessons of fires.
Dried compound: Dry compounds are accustomed to extinguish A-, B-, C-, or D-type fires. They work by putting an excellent coating of compound dirt on the substance that’s burning. Dry substance extinguishers are quite effective at getting out fires. Nevertheless, dried substance extinguishers may be aggressive and corrosive to technology and particular different materials. Co2: Co2 operates by eliminating oxygen from the quick location of the fire. Carbon dioxide extinguishers are only actually used for T (flammable liquid) and C (electrical fires) extinguishers. For pc, medical and clinical equipment, and aircraft technology, co2 will be a greater decision than dry chemical extinguishers just because a carbon dioxide extinguisher leaves number residue.
Metal/sand: Some school N bình chữa cháy mt3 use metal or sand, such as for example sodium chloride (NaCl) or powdered copper steel, to smother shoots from materials and material alloys. Sodium (sodium chloride–NaCl) is the absolute most commonly applied material in metal/sand extinguishers. NaCl extinguishers work nicely with fires involving magnesium, salt, potassium, alloys of potassium and sodium, uranium, and powdered aluminum.
Sodium carbonate extinguishers may also be utilized on shoots involving sodium, potassium, and alloys of potassium and sodium. Wherever strain rust of stainless steel is a concern, this type of fireplace extinguisher would be a greater decision than an NaCl extinguisher. Powdered copper (Cu) metal is used for shoots concerning lithium and lithium alloys. Graphite powder extinguishers are utilized on lithium fires as well as shoots that require high-melting-point metals like titanium and zirconium. Sodium-bicarbonate-based extinguishers are applied to fires involving material alkyls and pyrophoric liquids.
Halotron I is really a clear agent alternative to Halon 1211, that was prohibited from use because of its ozone depleting properties. Halotron I extinguishers are used for extinguishing fires in computer areas, clear areas, and where telecommunications equipment or electronics are present. Halotron leaves number residue and is nonconducting but is higher priced than carbon dioxide. It should be observed that Halotron I will not be made following 2015.
FE-36 (CleanGuard) extinguishers are yet another clear representative replacement for Halon 1211. FE-36 extinguishers are less poisonous than Halon 1211 and Halotron I and supposedly don’t have any ozone-depleting potential. FE-36 can be useful for shoots in computer rooms, clean rooms, and wherever telecommunications equipment or technology are present. Unlike Halotron I, FE-36 isn’t in the pipeline for phase-out.
Nonmagnetic fire extinguishers: Wherever strong magnets come in use, for example, near magnetic resonance imaging (MRI) or nuclear magnetic resonance spectrometers (NMRSs), nonmagnetic fire extinguishers must be chosen. The strong magnetic fields made by this sort of equipment could cause material cylinder fireplace extinguishers to fly across an area with lethal force.
