Light weight aluminum powder fire is defined by a high fire temperature level, quick melting rate, large eruptive power, solid induction heat. While burning, it was normally green blue fire as well as send out silvery white light, surge stress can be approximately 6.3 kg/cm2. To the surrounding structures as well as individual security have excellent harmful power as well as perniciousness. Therefore, dealing with light weight aluminum powder fire is hard. Initially the fire scene after surge is a lot more intricate; 2nd it requires to select best fire snuffing out representative while dealing with, as well as take the correct fire dealing with approaches; 3 because of solid induction heat, fire rescue are tough to shut; 4th is light weight aluminum powder lightweight, excellence tiny, very easy to fly, have to hold a mindful technique in battling, or else, will certainly make light weight aluminum powder dashes, kind of second surges, causing higher losses; 5 is the high fire temperature level, while the light weight aluminum powder looseness is little, hard to produce.
Light weight aluminum powder fire dangers: experienced smaller sized ignition resource in air can rupture right into fires; light weight aluminum powder discolored with oil airborne, such as stack storage space for a long period of time, enthusiast sticks around, additionally simple to trigger spontaneous custom aluminum cans burning or surge, as well as the smaller sized the light weight aluminum powder fragment dimension, the higher danger of surge, when it got to 40g/m3 focus over airborne, experience fire can blow up. As a result, in the monitoring of harmful chemicals, light weight aluminum powder is categorized as 2 combustible solids.
Snuffing out representative option
According to the above features, light weight aluminum powder fire combating must make use of 7150 snuffing out representative or completely dry chemical, completely dry sand as well as graphite powder, completely dry magnesium, and so on to combat the blaze. Due to the fact that this fire snuffing out representative can cover in the surface area of the burning light weight aluminum powder, to remove the air, as well as can properly avoid the light weight aluminum powder blowing to combine with air, so regarding attain the function of fire asphyxia.
In order to properly snuff out fire light weight aluminum powder, it needs to be properly pick and also use fire snuffing out representative. First of all, light weight aluminum powder ablaze can not be battling with water as well as foam, it is typically due to the fact that the light weight aluminum powder surface area has a layer of oxide movie usually will not respond with water. However the brand-new made light weight aluminum oxide or the movie has actually diminished light weight aluminum powder, as well as the fire or in a heat cooking light weight aluminum powder can swiftly respond with water as well as bubbles, discharge harmful eruptive burning hydrogen, as well as combined with air will certainly create eruptive combinations. Consequently, the light weight aluminum powder fire restriction combating with water and also foam.
Third, light weight aluminum powder lightweight, excellence, when experienced wind or gas jet is conveniently flying to develop eruptive mixes airborne. For that reason, light weight aluminum powder fire can not utilize co2 and also various other gases extinguishers to eliminate the blaze.
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 produce a percentage of light weight aluminum chloride plays catalytic duty, it frequently causes eruptive burning. For that reason, light weight aluminum powder fire likewise can not utilize CTC, 1211 fire snuffing out representative to combat the blaze.
Snuff out the light weight aluminum powder fire must be kept in mind the concerns as comply with
According to the attributes of light weight aluminum powder fire burning, in the combating procedure must focus on the adhering to inquiries. In the combating, it is not permitted to easily open up the home window to prevent the wind makes light weight aluminum powder flying, creating a surge wounding. Firemans need to focus on observe and also use the surface as cover, to stay clear of radiation warm, warm body, homes collapse and also created surge casualties. Make complete use safety and security tools, prepared to shield themselves, to help with group activity. Prompt closure the workshop mill and also procedure systems of different shutoffs, initially quit device, power blackout and afterwards battling the blaze.
