There are many causes of fire, such as oil fire, electrical equipment fire, etc. There are a lot of combustion engines (oxygen and liquid oxygen) in the oxygen workshop, which are more dangerous. Fire extinguisher, sand, water, nitrogen, etc. Different fire extinguishing equipments should be adopted for different fire methods. First of all, we should distinguish the objects and do not use them casually in order to avoid causing danger.
When liquid or oil, whose density is smaller than water, and water-soluble, is on fire, if water is used to put out the fire, the fire area will be enlarged. Sand, steam or foam fire extinguisher should be used to extinguish it, or air insulation should be used to extinguish it.
When the electrical equipment is on fire, neither foam fire extinguisher nor water is allowed to extinguish the fire. Instead, carbon Chloride fire extinguisher is needed. Because both water and foam have electrical conductivity, they are likely to cause electric shock to the firefighters. When the electric wire is on fire, the power should be cut off first and then put out with sand.
Generally, when solid is on fire, sand or water can be used to extinguish it.
When the oxygen pipeline is on fire, the gas source should be cut off first.
If you are on fire with your clothes, you should not beat your body. You should wrap your body with a fire blanket and roll back and forth on the ground.
In the dangerous parts of the workshop, some nitrogen cylinders or nitrogen pipelines can be prepared in advance for fire fighting.
