Light weight aluminum powder fire is defined by a high fire temperature level, quick shedding rate, huge eruptive power, solid induction heat. While burning, it was normally green blue fire and also discharge silvery white light, surge stress can be as much as 6.3 kg/cm2. To the surrounding structures and also individual security have fantastic 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 intricate; 2nd it requires to pick appropriate fire snuffing out representative while battling, as well as take the appropriate fire dealing with techniques; 3 because of solid induction heat, fire rescue are challenging to shut; 4th is light weight aluminum powder lightweight, excellence little, simple to fly, should hold a mindful strategy in combating, or else, will certainly make light weight aluminum powder sprinkles, type of additional surges, causing higher losses; 5 is the high fire temperature level, while the light weight aluminum powder looseness is tiny, challenging to produce.
Light weight aluminum powder fire risks: run into smaller sized ignition resource in air can break right into fires; light weight aluminum powder discolored with oil airborne, such as stack storage space for a very long time, enthusiast sticks around, additionally simple to create spontaneous burning or surge, as well as the smaller sized the light weight aluminum powder bit dimension, the better threat of surge, when it got to 40g/m3 focus over airborne, experience fire can take off. As a result, in the monitoring of unsafe chemicals, light weight aluminum powder is categorized as 2 combustible solids.
Snuffing out representative choice
In order to successfully snuff out fire light weight aluminum powder, it has to be appropriately pick as well as use fire snuffing out representative. To start with, light weight custom aluminum cans aluminum powder ablaze can not be combating with water as well as foam, it is generally due to the fact that the light weight aluminum powder surface area has a layer of oxide movie typically will not respond with water. Yet 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 promptly respond with water as well as bubbles, release harmful eruptive burning hydrogen, as well as blended with air will certainly create eruptive mixes. Consequently, the light weight aluminum powder fire restriction combating with water as well as foam.
Second of all, light weight aluminum powder at space 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 typically brings about eruptive burning. Consequently, light weight aluminum powder fire likewise can not make use of CTC, 1211 fire snuffing out representative to eliminate the blaze.
According to the above features, light weight aluminum powder fire combating must utilize 7150 snuffing out representative or completely dry chemical, completely dry sand and also 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, and also can properly avoid the light weight aluminum powder blowing to combine with air, so regarding attain the objective of fire asphyxia.
Third, light weight aluminum powder lightweight, excellence, as soon as came across wind or gas jet is conveniently flying to develop eruptive blends airborne. As a result, light weight aluminum powder fire can not utilize co2 as well as various other gases extinguishers to eliminate the blaze.
Snuff out the light weight aluminum powder fire need to be kept in mind the concerns as adhere to
According to the qualities of light weight aluminum powder fire burning, in the dealing with procedure must take notice of the adhering to inquiries. In the battling, 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. Firemens must focus on observe and also use the surface as cover, to prevent radiation warm, warm body, homes collapse as well as created surge casualties. Make complete use security devices, prepared to safeguard themselves, to help with group activity. Prompt closure the workshop mill as well as procedure systems of different shutoffs, initially quit maker, power blackout and afterwards dealing with the blaze.
