Carbon dioxide fire extinguisher Introduction
Carbon dioxide extinguisher is a fire extinguisher that uses liquid carbon dioxide filled to spray out a fire. It is composed of cylinder, valve, injection system and other components. Divided into: (1) portable carbon dioxide fire extinguisher. The total weight is less than or equal to 28kg, its specifications are 2kg, 3.5kg, 5kg, 7kg four kinds; (2) wheeled carbon dioxide fire extinguisher. The total weight is greater than 28kg, and its specifications are 20kg and 25kg. Carbon dioxide fire extinguishers are suitable for fighting the initial fire of various flammable liquids and flammable gases. As well as live equipment and precision electronic instruments, valuable equipment fire. However, it should not be used when the wind blows outdoors, and after the use of a narrow and confined space, timely ventilation or personnel evacuation from the scene should be required to prevent suffocation.
Fire extinguishing principle
When pressurized, the liquid carbon dioxide is compressed in a small cylinder, and then it is ejected when extinguishing the fire, which has the effect of cooling and isolating the air.
Carbon dioxide fire extinguishers are mainly used to save valuable equipment, archives, instruments, electrical equipment below 600 volts and the initial fire of oil.
Scope of application
With good fluidity, high injection rate, non-corrosive containers and not easy to deteriorate and other excellent properties, used to extinguish books, archives, valuable equipment, precision instruments, electrical equipment below 600 volts and oil initial fire. Suitable for fighting Class B fires (such as kerosene, diesel, crude oil, methanol, ethanol, asphalt, paraffin, etc.) Suitable for fighting Class C fires (such as gas, natural gas, methane, ethane, propane, hydrogen, etc.) Fight Class E fires (fires in which objects burn with electricity).
