Light weight aluminum powder fire is identified by a high fire temperature level, quickly shedding rate, large eruptive power, solid convected heat. While burning, it was normally green blue fire and also release silvery white light, surge stress can be approximately 6.3 kg/cm2. To the surrounding structures as well as individual safety and security have terrific devastating power as well as perniciousness. Hence, combating light weight aluminum powder fire is tough. Initially the fire scene after surge is much more intricate; 2nd it requires to pick ideal fire snuffing out representative while combating, as well as take the correct fire combating approaches; 3 as a result of solid induction heat, fire rescue are hard to shut; 4th is light weight aluminum powder lightweight, excellence little, very easy to fly, should hold a careful method in combating, or else, will certainly make light weight aluminum powder dashes, type of additional surges, causing better losses; 5 is the high fire temperature level, while the light weight aluminum powder looseness is tiny, tough to produce.
Light weight aluminum powder fire threats: run into smaller sized ignition resource in air can rupture right into fires; light weight aluminum powder tarnished with oil airborne, such as load storage space for a very long time, enthusiast remains, likewise simple to trigger spontaneous 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 take off. As a result, in the administration of dangerous chemicals, light weight aluminum powder is identified as 2 combustible solids.
Snuffing out representative choice
Third, light weight aluminum powder lightweight, excellence, when experienced wind or gas jet is quickly flying to create eruptive mixes airborne. As a result, light weight aluminum powder fire can not make use of 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 as well as bromine, additionally can respond with halogenated alkyl to create a percentage of light weight aluminum chloride plays catalytic function, it usually brings about eruptive burning. For that reason, 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 qualities, light weight aluminum powder fire battling need to make use of 7150 snuffing out representative or completely dry chemical, completely dry sand and also graphite powder, completely dry magnesium, and so on to eliminate 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 custom aluminum cans the air, as well as can successfully avoid the light weight aluminum powder blowing to blend with air, so regarding accomplish the objective of fire asphyxia.
In order to properly snuff out fire light weight aluminum powder, it should be properly select as well as use fire snuffing out representative. To start with, light weight aluminum powder ablaze can not be battling 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. Yet the brand-new made light weight aluminum oxide or the movie has actually diminished light weight aluminum powder, and also the fire or in a heat cooking light weight aluminum powder can rapidly respond with water as well as bubbles, produce unsafe 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.
Snuff out the light weight aluminum powder fire ought to be kept in mind the problems as adhere to
According to the features of light weight aluminum powder fire burning, in the dealing with procedure needs to focus on the adhering to concerns. In the battling, it is not enabled to easily open up the home window to prevent the wind makes light weight aluminum powder flying, creating a surge wounding. Firemans need to take note of observe and also use the surface as cover, to prevent radiation warmth, warm body, residences collapse and also triggered 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 maker, power failure and afterwards combating the blaze.
