Difference and usage of carbon dioxide fire extinguisher and dry powder fire extinguisher
When the fire extinguishing, as long as the fire extinguisher spray barrel aligned with the fire source, open the valve, the liquid carbon dioxide immediately gasification, and in high-pressure action, rapid jet. Using the handwheel, can remove the aluminum seal, in accordance with the handwheel counterclockwise, the valve can be opened; the use of duckbill type, can be the right hand pulled out the pin at the same time, with the left hand to hold the pressure, then the valve is opened.
Carbon dioxide is suffocating gas, harmful to humans, should pay attention to safety when using. At the time of the fire, to prevent the resurgence embers of continuous injection. Such as outdoor, you can not use the wind.
Carbon dioxide fire extinguishing agent is a kind of low temperature liquefied gas, can reduce the oxygen content and reduce the surface temperature of combustion air, the combustion physical disruption of the fire extinguishing principle, leaving no trace, and certain insulation performance etc.. Therefore, it is suitable for extinguishing the first fire, such as electrical appliances, precious equipment, books, archives, instruments and meters, etc. under 600 volts (V), as well as general B fire. Is a vehicle, ships, factories, scientific research units, museums and other essential fire equipment.
Carbon dioxide fire extinguishers will soon be filled with high-pressure liquid carbon dioxide in the tank, filling capacity of 2 kg (kg), 3 kg (kg), 5 kg (kg), 7 kg (kg) of four specifications.
