How to use fire mask to save people from fire
Modern high-rise buildings are decorated with more plastic decoration and wooden furnishings, and a considerable number of families use a lot of foam-filled furniture. These decoration items are beautiful, but if they are caught in a fire, the spread will be very fast. And during the extinguishing process, a large amount of toxic smoke, such as carbon monoxide and hydrogen cyanide, will be generated. Toxic smoke is one of the main reasons for the obstacles to escape and lead to the unfortunate death of people. There are two main aspects of fire-related casualties: one is the suffocation of smoke and poisonous gas, and the other is the burn of flames and powerful heat radiation. As long as you can avoid or reduce these two hazards, you can maintain your own safety and reduce injuries. Therefore, to control some of the fire rescue tips, you may be able to achieve a second life in a dilemma.
According to the statistics of the cause of casualties in fires in the United Kingdom, people who died of suffocation due to carbon monoxide poisoning or other toxic fumes generally accounted for more than 90% of the total number of deaths from fires. He was poisoned, suffocated, collapsed, and buried in flames. Therefore, if the filter-type fire-fighting self-rescue respirator can be worn in the early stage of the fire to filter out the poisonous gas produced by the extinguisher, the wearer can fight for more escape time and rescue time. Filtered self-rescue fire fighting respirators, also known as gas masks, smoke masks, fire escape masks, etc., are generally deployed in public places and residences such as hotels, offices, hospitals, shopping malls, airport waiting halls, and entertainment venues for people to have a fire. Time to escape. Gas masks can filter carbon monoxide (CO), hydrogen cyanide (HCN) and other toxic fumes, due to a key filter installation-the canister. The canister can filter carbon monoxide (CO) due to a catalyst (Hogarat agent) layer inside. The catalyst is a kind of catalyst. When carbon monoxide (CO) passes through the filter canister, it reacts with oxygen in the air to produce carbon dioxide (CO2) which is harmless to the human body. Because the catalyst is very easy to absorb the moisture in the air and fail, the canister is also added with a drying agent layer in front of the catalyst layer. When in use, the drying agent layer first filters out the water entering the canister, so that the catalyst layer can play its maximum role. Hogarat agent is also known as catalyst: it is a granular catalyst made of active manganese dioxide and copper oxide in a certain proportion, and it is generally used in the protection of gas. Hogarate agent is a catalyst with good CO oxidation at room temperature. It has the characteristics of low cost and high catalytic performance, and can adsorb carbon monoxide, so it is widely used in filter self-rescue respirators.
Carbon monoxide removal catalyst, also called CO removal catalyst and Hopcalite catalyst, is mixture of Copper Oxide and Manganese Dioxide, Carbon monoxide removal catalyst is used to convert carbon monoxide into carbon dioxide . With advantage of low cost and high efficiency, XINTAN Carbon monoxide removal catalyst is widely applied in fire escape equipment, diving devices , air-purifying respirator, environmental protecting ,mine rescue, exhaust treatment other fields . We have gained favor of domestic and foreign customers. Although primarily used to converting carbon monoxide to carbon dioxide, Hopcalite catalysts is also used to remove ethylene oxide and other VOCs as well as ozone from gas streams.
