What are the advantages of heptafluoropropane gas fire extinguishing system compared with water fire extinguishing? Heptafluoropropane gas fire extinguishing agent is a clean, safe and rapid fire extinguishing agent. Fire extinguishing principle The fire extinguishing principle of the sevoflurane gas fire extinguishing system is that the heat capacity of the agents and air inclusions is much higher than that of pure air, and a large amount of heat is absorbed to reach the goal of cooling; at the same time, there is a chemical action that stops the incineration reaction chain.
After entering the autumn, the north is windy, the weather is dry, and it is easy to catch fire. In some southern areas, it is rainy, and the electrical lines are wet, and it is easy to cause short circuits to cause fires. In fact, many fires in life can be prevented and avoided. This autumn, Chongqing Jiangbei Firefighting and everyone will learn how to avoid causing fire. First, avoid fires in electrical lines. Among household fires, fires caused by aging circuits account for a large proportion, especially in old residential areas. This phenomenon is more prominent. Therefore, in the daily life of citizens, don't pull the wires in a random way. In wet environments such as kitchens and bathrooms, take measures to protect the circuit leakage. In rainy areas in autumn, citizens often check the electrical wiring in their houses.
Carbon dioxide is the earliest extinguishing agent used in gas fires. In the fire extinguishing solution of the power distribution room, carbon dioxide is widely welcomed by customers because of its one-time investment and low maintenance cost of Nissan. However, from the perspective of instrument protection and personnel safety, there are some deficiencies in the carbon dioxide fire extinguishing system. On the one hand, carbon dioxide stored in liquid or solid state vaporizes and absorbs heat during injection, which causes the temperature of the protected area to drop rapidly for a short period of time, causing "cold shock" and "cold quenching" phenomena, which damages precision instruments to a certain extent. On the other hand, to achieve the fire extinguishing effect, the fire extinguishing concentration of carbon dioxide is greater than the asphyxiating concentration of people, which is not suitable for places where people often stay. ?
The method of using a carbon dioxide fire extinguisher is to lift the fire extinguisher with one hand and remove the safety pin with the other hand. Unscrew the handwheel or press the handle on the fire extinguisher, and then hold the nozzle or point the nozzle at the root of the flame. , And gradually move forward.
The method of using the foam fire extinguisher is a portable fire extinguisher, and the other hand supports the base of the fire extinguisher. Turn the fire extinguisher completely with both hands, and place it diagonally in front of the chest so that the foaming agent from the nozzle is directed at the root of the flame Sweep and gradually advance forward.
The use of dry powder fire extinguisher is to lift the fire extinguisher with one hand, pull out the safety latch with the other hand, press the handle, and then hold the nozzle or direct the nozzle to the root of the flame and gradually advance.
Can extinguish fires of Class A solid substances, Class B combustible liquids, Class C gases and fires of live equipment, but cannot extinguish fires of light metals.
