Fireplace extinguishers use various components for extinguishing fires. When selecting your extinguisher, you need to find out which kind of fireplace you might be preventing and then choose the best extinguishing substance for your application. Water: Water, or APW, extinguishers use condensed water to extinguish fires. APW extinguishers can only be useful for Class A shoots (combustibles such as report, towel, etc.); they cannot be useful for putting out different courses of fires.
Dried compound: Dry substances are used to extinguish A-, B-, C-, or D-type fires. They function by adding a fine layer of chemical dust on the product that is burning. Dried chemical extinguishers are very efficient at placing out fires. However, dry chemical extinguishers can be harsh and harsh to technology and specific different materials. Carbon dioxide: Co2 performs by eliminating oxygen from the immediate location of the fire. Carbon dioxide extinguishers are only ever used for B (flammable liquid) and D (electrical fires) extinguishers. For computer, medical and medical gear, and aircraft electronics, carbon dioxide will be a greater decision than dry substance extinguishers must be co2 extinguisher leaves number residue.
Metal/sand: Some school N bình chữa cháy mfz4 use steel or mud, such as for example salt chloride (NaCl) or powdered copper material, to smother shoots from materials and metal alloys. Salt (sodium chloride–NaCl) is probably the most generally applied product in metal/sand extinguishers. NaCl extinguishers work nicely with shoots concerning magnesium, salt, potassium, alloys of potassium and salt, uranium, and powdered aluminum.
Sodium carbonate extinguishers are also utilized on fires involving sodium, potassium, and alloys of potassium and sodium. Where pressure rust of metal is a thought, this kind of fireplace extinguisher would have been a greater decision than an NaCl extinguisher. Powdered copper (Cu) material is employed for fires involving lithium and lithium alloys. Graphite dust extinguishers are used on lithium fires as well as fires that require high-melting-point metals like titanium and zirconium. Sodium-bicarbonate-based extinguishers are applied to fires concerning steel alkyls and pyrophoric liquids.
Halotron I is just a clean agent replacement Halon 1211, which was banned from use because of its ozone depleting properties. Halotron I extinguishers are used for extinguishing shoots in computer rooms, clean rooms, and where telecommunications gear or electronics are present. Halotron leaves number deposit and is nonconducting but is higher priced than carbon dioxide. It must be observed that Halotron I will not be made following 2015.
FE-36 (CleanGuard) extinguishers are yet another clean agent replacement for Halon 1211. FE-36 extinguishers are less hazardous than Halon 1211 and Halotron I and supposedly haven’t any ozone-depleting potential. FE-36 can also be used for fires in computer rooms, clean rooms, and where telecommunications gear or electronics are present. Unlike Halotron I, FE-36 isn’t in the pipeline for phase-out.
Nonmagnetic fire extinguishers: Wherever strong magnets come in use, like, near magnetic resonance imaging (MRI) or nuclear magnetic resonance spectrometers (NMRSs), nonmagnetic fire extinguishers must certanly be chosen. The solid magnetic fields produced by this sort of gear can cause material cylinder fireplace extinguishers to fly across an area with fatal force.
