滅火器滅火時的噴射口應該對準火焰哪里？
川消小編給您講，實際上用滅火器滅火時，滅火器的噴射口應該對準火焰的根部。下面我們從兩方面內容了解起來。
Where should the nozzle of the fire extinguisher aim at the fire? Chuan Xiaobian told you that when using a fire extinguisher to extinguish a fire, the nozzle of the fire extinguisher should aim at the root of the flame. Now let's learn from two aspects.
干粉滅火器：
Dry powder fire extinguisher:
滅火時，可手提或肩扛滅火器快速奔赴火場，在距燃燒處5米左右，放下滅火器。如在室外，應選擇在上風方向噴射。使用的干粉滅火器若是外掛式儲壓式的，操作者應一手緊握噴槍、另一手提起儲氣瓶上的開啟提環。
When putting out a fire, you can quickly rush to the fire site with a portable or shoulder mounted extinguisher, and put down the extinguisher about 5 meters away from the burning place. If it is outdoors, spray in the upwind direction. If the dry powder extinguisher used is of externally mounted pressure storage type, the operator shall hold the spray gun with one hand and lift the opening bail on the gas cylinder with the other hand.
如果儲氣瓶的開啟是手輪式的，則向逆時針方向旋開，并旋到高位置，隨即提起滅火器。當干粉噴出后，迅速對準火焰的根部掃射。
If the opening of the gas cylinder is handwheel type, unscrew it counterclockwise, rotate it to the high position, and then lift the fire extinguisher. When the dry powder is sprayed, it should be aimed at the root of the flame quickly.
使用的干粉滅火器若是內置式儲氣瓶的或者是儲壓式的，操作者應先將開啟把上的保險銷拔下，然后握住噴射軟管前端噴嘴部，另一只手將開啟壓把壓下，打開滅火器進行滅火。有噴射軟管的滅火器或儲壓式滅火器在使用時，一手應始終壓下壓把，不能放開，否則會中斷噴射。
If the dry powder extinguisher used is of built-in gas cylinder or pressure storage type, the operator should first pull out the safety pin on the opening handle, and then hold the nozzle at the front of the spray hose, with the other hand, press the opening handle down, and open the extinguisher to extinguish the fire. When using a fire extinguisher with a spray hose or a pressure storage fire extinguisher, always press the handle down with one hand and do not release it, otherwise the spraying will be interrupted.
二氧化碳滅火器：
Carbon dioxide extinguisher:
滅火時只要將滅火器提到或扛到火場，在距燃燒物5米左右，拔出滅火器保險銷，一手握住喇叭筒根部的手柄，另一只手緊握啟閉閥的壓把。對沒有噴射軟管的二氧化碳滅火器，應把喇叭筒往上板70-90度。
When putting out a fire, just lift or carry the extinguisher to the fire site, pull out the safety pin of the extinguisher at a distance of about 5 meters from the combustor, and hold the handle at the bottom of the horn with one hand and the handle of the on-off valve with the other hand. For carbon dioxide extinguishers without jet hoses, the horn shall be 70-90 degrees higher than the upper plate.
使用時，不能直接用手抓住喇叭筒外壁或金屬連線管，防止手被凍傷。滅火時，當可燃液體呈流淌狀燃燒時，使用者將二氧化碳滅火劑的噴流由近而遠向火焰噴射。
When using, do not directly grasp the outer wall of the horn or the metal connecting pipe with your hands to prevent your hands from being frostbitten. When putting out a fire, when the flammable liquid burns in flowing form, the user sprays the carbon dioxide extinguishing agent from near to far to the flame.
如果可燃液體在容器內燃燒時，使用者應將喇叭筒提起。從容器的一側上部向燃燒的容器中噴射。但不能將二氧化碳射流直接沖擊可燃液面，以防止將可燃液體沖出容器而擴大火勢，造成滅火困難。
If the flammable liquid burns in the container, the user should lift the horn. Spray from the upper side of the container into the burning container. However, it is not allowed to directly impact the flammable liquid surface with the carbon dioxide jet, so as to prevent the flammable liquid from rushing out of the container and expanding the fire, causing difficulty in extinguishing.
The above is the relevant answer to the question. If you are interested in understanding or need to buy fire-fighting equipment such as fire extinguishers, please come to our website http://m.xintli.net Consult.
