In metallurgical production, a large number of gas are produced and used: blast furnace gas, coke oven gas, converter gas, producer gas and ferroalloy gas. The components and percentages of various kinds of gas are different. The main components are carbon monoxide, hydrogen, methane, nitrogen, carbon dioxide, etc.
Gas is one of the main hazard sources in metallurgical production, and its main hazards are corrosion, toxicity, combustion and explosion. The main categories of gas accidents are: acute poisoning and suffocation accidents, fire and burning accidents caused by combustion, explosion injury and damage accidents caused by explosion.
The main causes of gas accidents in metallurgical production process are: illegal operation or misoperation, defects of equipment (facilities) and protective devices, lack of safety technology knowledge, lack of inspection guidance and monitoring measures on site, lack of monitoring device and personal protective equipment, and imperfect accident prevention and rescue measures.
Oxygen is widely used in metallurgical production. Oxygen is easy to support combustion and can be burned with almost all combustible materials. When mixed with other combustible gases in a certain proportion, it is easy to explode. The main danger is easy to burn and explode. When oxygen burns, the temperature is usually very high, the fire is very fierce, and the disaster is serious. The burning and burning accidents caused by oxygen combustion are often large and deep, which are difficult to cure. Oxygen explosion is usually very strong, very violent, impact, destructive and destructive.
