Light weight aluminum powder fire is identified by a high fire temperature level, quick melting rate, huge eruptive power, solid induction heat. While burning, it was usually green blue fire and also send out silvery white light, surge stress can be as much as 6.3 kg/cm2. To the surrounding structures and also individual security have excellent devastating power as well as perniciousness. Hence, dealing with light weight aluminum powder fire is challenging. Initially the fire scene after surge is much more complicated; 2nd it requires to select best fire snuffing out representative while battling, as well as take the correct fire battling techniques; 3 because of solid induction heat, fire rescue are challenging to shut; 4th is light weight aluminum powder lightweight, excellence tiny, simple to fly, need to hold a mindful strategy in combating, or else, will certainly make light weight aluminum powder dashes, kind of second surges, leading to higher losses; 5 is the high fire temperature level, while the light weight aluminum powder looseness is tiny, hard to produce.
Light weight aluminum powder fire dangers: run into smaller sized ignition resource in air can break right into fires; light weight aluminum powder discolored with oil airborne, such as lot storage space for a very long time, collection agency sticks around, additionally simple to create spontaneous burning or surge, as well as the smaller sized the light weight aluminum powder fragment dimension, the better danger of surge, when it got to 40g/m3 focus over airborne, experience fire can blow up. For that reason, in the administration of unsafe chemicals, light weight aluminum powder is identified as 2 combustible solids.
Snuffing out representative option
Second of all, light weight aluminum powder at area temperature level can have a burning response with chlorine and also bromine, likewise can respond with halogenated alkyl to create a percentage of light weight aluminum chloride plays catalytic duty, it usually results in eruptive burning. As a result, light weight aluminum powder fire additionally can not make use of CTC, 1211 fire snuffing out representative to eliminate the blaze.
In order to successfully snuff out fire light weight aluminum powder, it has to be appropriately select as well as use fire snuffing out representative. First of all, light weight aluminum powder ablaze can not be combating with water and also foam, it is typically due to the fact that the light weight aluminum powder surface area has a layer of oxide movie normally will not respond with water. However the brand-new made light weight aluminum oxide or the movie has actually diminished light weight aluminum powder, and also the fire or in custom aluminum cans a heat cooking light weight aluminum powder can promptly respond with water and also bubbles, produce dangerous eruptive burning hydrogen, as well as combined with air will certainly develop eruptive blends. For that reason, the light weight aluminum powder fire restriction combating with water as well as foam.
Third, light weight aluminum powder lightweight, excellence, as soon as ran into wind or gas jet is conveniently flying to create eruptive blends airborne. As a result, light weight aluminum powder fire can not utilize co2 and also various other gases extinguishers to eliminate the blaze.
According to the above attributes, light weight aluminum powder fire combating ought to utilize 7150 snuffing out representative or completely dry chemical, completely dry sand as well as graphite powder, completely dry magnesium, and so on to eliminate the blaze. Since this fire snuffing out representative can cover in the surface area of the burning light weight aluminum powder, to remove the air, and also can efficiently avoid the light weight aluminum powder blowing to combine with air, so regarding attain the objective of fire asphyxia.
Snuff out the light weight aluminum powder fire ought to be kept in mind the problems as adhere to
According to the qualities of light weight aluminum powder fire burning, in the battling procedure needs to focus on the complying with inquiries. In the combating, it is not permitted to easily open up the home window to stay clear of the wind makes light weight aluminum powder flying, creating a surge wounding. Firemens ought to take note of observe as well as use the surface as cover, to stay clear of radiation warmth, warm body, homes collapse as well as created surge casualties. Make complete use safety and security devices, prepared to shield themselves, to promote group activity. Prompt closure the workshop mill and also procedure systems of numerous shutoffs, initially quit device, power interruption and afterwards dealing with the blaze.
