Fire extinguisher hazards.

Halon extinguishing agents, which are widely used in the fire protection industry, are ozone-depleting substances and are one of the main culprits in the destruction of the ozone layer. When people use halon fire extinguishers to fight fires or train, halon gas is naturally emitted into the atmosphere.

Halons contain chlorine and bromine, which decompose free radicals of chlorine and bromine after being exposed to sunlight radiation in the atmosphere, and these chemically active groups combine with ozone to take away an oxygen atom in the ozone molecule, triggering a destructive chain reaction that destroys the ozone layer, thereby reducing ozone concentration and producing an ozone hole.

Halons live decades in the atmosphere, and their depletion of the ozone layer in the stratosphere will last for decades or more. Therefore, the destructive effect of halons on the ozone layer is enormous.

1211 is the code name of difluorochloro-bromomethyl dichloride this chemical agent, 1211 fire extinguisher is loaded with this haloalkane, it is a low boiling point of liquefied gas, with high fire extinguishing efficiency, low toxicity, low corrosion, long-term storage without deterioration, no trace after extinguishing the fire, no pollution of the protected substance, good insulation performance and so on. It is a gas fire extinguisher. Hope my explanation is helpful to you!

1211 is the code name of difluorochloro-bromomethane, which is a discontinued fire extinguisher and is no longer in circulation.

1211 fire extinguishing agent is a liquefied gas with low boiling point, which has the advantages of high fire extinguishing efficiency, low toxicity, low corrosiveness, long-term storage without deterioration, no trace after fire extinguishing, and good insulation performance. However, due to the strong destructive effect of the fire extinguishing agent on the ozone layer, China has stopped production in 2005.

Extended Materials. Fire extinguishing principle:

The fire extinguishing agent is in a pressurized liquefaction state in the cylinder, and the fire extinguishing agent sprayed from the cylinder is a mixture of fine droplets and vapors, which is heated when in contact with the combustible material and produces bromine ions and hydrogen free radicals, so that the combustion chain reaction is quickly stopped and the fire is extinguished.

The explosion suppression peak of 1211 is small, and the combustion of 1211 mixed with 6 7% volume of flammable gas stops, it is especially suitable for extinguishing fires such as oil organic solvents, high-voltage electrical equipment and precision instruments, and its fire extinguishing efficiency is more than 4 times higher than that of carbon dioxide.

It should be noted that when extinguishing the fire, it is necessary to maintain an upright position, not to be used horizontally or upside down, and the nozzle should be aimed at the root of the flame, from near to far, and quickly advance and strafe; To prevent the recurrence of flashbacks, sporadic small fires can be fired.

In case of combustible liquid burning in the container, the jet of 1211 fire extinguishing agent can be sprayed to the inner wall of the container from top to bottom. If extinguishing a fire on the surface of a solid substance, the nozzle should be aimed at the place where the burning is most violent, and the spray should be sprayed left and right.

Summary. The 1211 fire extinguisher is one of the types of alkyl halide fire extinguishers.

The 1211 fire extinguisher is one of the types of alkyl halide fire extinguishers.

1211 fire extinguishing agent is a liquid holding gas with low boiling point, which has the advantages of high fire extinguishing efficiency, low toxicity, low corrosion, long-term storage without deterioration, no trace after fire extinguishing, no pollution of the protected substance, and good insulation performance. This type of fire extinguisher, the use of nitrogen pressure installed in the hole casing cylinder will be 1211 fire extinguishing agent sprayed out of the fire extinguishing, it belongs to the pressure storage type, 1211 is the code of difluorochloro-bromomethane, it was once the most widely produced and used halide fire extinguishing agent in China, in a liquid tank in the cylinder, but because the fire extinguishing agent has a strong destructive force on the ozone layer, China has stopped production in 2005.

It belongs to the pressure storage type fire extinguisher, the main components of which are difluorochloro-bromomethane, when extinguishing the fire, it mainly relies on nitrogen to spray out the internal difluorochloro-bromomethane, so as to achieve the effect of fire extinguishing, suitable for extinguishing combustible gas, liquid and other fires, but the use of this fire extinguisher is very harmful to the environment. What are the types of common fire extinguishers1, dry powder fire extinguishers Zaojing, mainly sodium bicarbonate and ammonium phosphate two components of fire extinguishers, can be used for some flammable, combustible pages, gases and fires caused by electrical equipment, can also be used for fires caused by solid substances, but can not be used to extinguish the fire of metal burning benches. 2. Foam fire extinguishers, which are mainly carbon dioxide and foam, are usually used to extinguish Class B fires, such as oil or grease, etc., but cannot be used to extinguish fires that are water-soluble or carry flammable liquids, such as fires caused by some chemical substances alcohol, esters, ethers, ketones, etc., and cannot be used for fires caused by some power equipment.

3. Carbon dioxide fire extinguisher is mainly used to extinguish the fire through the dry ice inside the bottle, which can extinguish the general fire in life and some valuable equipment, archives and other fires, and can also be used for fires caused by some electrical equipment, but can not be used for high-voltage electricity ignition and oil ignition above 600 volts.
