What should I do with sulfur hexafluoride gas poisoning?

Sulfur hexafluoride itself is a non-toxic and harmless gas, but under the action of high temperature and high pressure arc, it tends to decompose and free a variety of products, mainly S2F10, SF4 and SF2, as well as a small amount of S2, F2, S, F, etc. Some of these decomposers are toxic substances that will cause harm to the human body. At the same time, if a large amount of sulfur hexafluoride gas is inhaled, it will also cause adverse reactions such as asphyxia. But sulfur hexafluoride gas is the "oxygen" that is not available in the power industry, in case of sulfur hexafluoride gas poisoning? How to prevent sulfur hexafluoride gas poisoning? How do we know if sulfur hexafluoride is poisoned?

Prevention of sulfur hexafluoride gas poisoning

Why does sulfur hexafluoride gas poisoning occur? Due to technical problems and other reasons, the purity of some SF6 gas products is not up to standard, and there will be some harmful impurities when leaving the factory. There is also a case that when dealing with SF6 gas equipment, personnel improper operation, resulting in SF6 power equipment leakage, toxic and harmful substances leakage, resulting in sulfur hexafluoride gas poisoning. Of course, there are also some companies in the regular inspection of leakage and cut corners, resulting in equipment failure, resulting in sulfur hexafluoride gas poisoning.

What are the symptoms of sulfur hexafluoride gas poisoning? How do we self-check for sulfur hexafluoride gas poisoning? The toxic gases in sulfur hexafluoride gas and the dust produced in the equipment have certain harm to the human respiratory system and mucous membranes. Generally, after sulfur hexafluoride gas poisoning, there will be different degrees of tears, sneezing, runny nose, hot sensation in the nose and throat, hoarseness, cough, dizziness, nausea, chest tightness, neck discomfort and other symptoms. In the event of such poisoning, the person affected by sulfur hexafluoride gas should be promptly moved to a place with fresh air and treated in time.

Is sulfur hexafluoride gas poisoning serious? Once the sulfur hexafluoride gas encounters high heat, high temperature (such as: electric arc), it will produce byproducts - sulfur oxide and hydrogen fluoride gas, which coexist with the undecomposed sulfur hexafluoride gas. At this point, there are three types of gases. Sulfur oxide is a kind of sulfuric anhydride, which is easily absorbed by the wet mucous membrane surface of the human body to produce sulfuric acid and sulfite, and has a strong irritating effect on the eyes and respiratory mucosa. The specific manifestations are tears, cough, burning throat, eye conjunctiva and respiratory tract tingling symptoms. When you encounter human sweat, your skin will become red and swollen. Hydrogen fluoride, soluble in water. It is also easily absorbed by the body's wet mucous membrane surface to produce hydrofluoric acid, which is as harmful to the human body as sulfur oxide - the eyes and respiratory tract, but more harmful. Hydrofluoric acid is often used to etch glass, which shows that it is extremely corrosive. If you encounter human sweat, the formation of hydrofluoric acid on the surface of the skin, it can penetrate the surface of the skin to the deep penetration, the formation of ulcers and necrosis, and not suitable for cure. If bone damage causes bone fluorosis, there is no recovery. Hydrogen fluoride is more toxic than sulfur oxide and sulfur hexafluoride.

What are the regulations for preventing sulfur hexafluoride gas poisoning?

Agencies at all levels should set up a dedicated sulphur hexafluoride safety protection post in the safety department to be responsible for the safety protection of sulphur hexafluoride gas. Operation, maintenance, testing departments should have full-time personnel responsible for safety protection. Sulfur hexafluoride safety protection should be included in the scope of chemical technical supervision. All kinds of safety monitoring instruments should be regularly calibrated and calibrated to be in good condition at any time. Equipment operation, maintenance and gas test personnel should be given nutrition and health subsidies. Staff engaged in sulfur hexafluoride gas test, operation, maintenance and supervision should be examined once or twice a year, the physical examination items should have special requirements (such as blood phase, respiratory system, skin, bone density, etc.), and establish health records.
