The main causes of oxygen accidents in metallurgical production are fire and burn accidents caused by oxygen combustion or combustion supporting, and explosion accidents caused by oxygen explosion. The degree of damage and damage is very serious. Analysis and statistics show that the main causes of oxygen accidents in metallurgical production are: man-made illegal operation and misoperation, defects of equipment and facilities, lack of safety technology knowledge and unskilled operation.

Nonferrous metal smelting production includes smelting and processing of copper, lead, zinc, aluminum and other rare and precious metals. Its production process has the characteristics of complex equipment and process, wide range of equipment and facilities, various types of work, cross operation, frequent operation and many risk factors. The main hazard sources are: high temperature, noise, smoke and dust hazards, toxic and harmful, flammable and explosive gases and other substances poisoning, combustion and explosion hazards, various furnace operation and operation risks, falling accidents from high places, etc.

According to the statistical analysis of previous accidents, the main causes of safety accidents in nonferrous metal smelting production are: illegal operation and not familiar with, do not understand safe operation technology, process equipment defects and technical design defects, protection device failure or defect, lack of on-site inspection and guidance, imperfect or lax implementation of safety rules and regulations, and poor working environment conditions.

The main hazard sources in the process of gold smelting are: high temperature, noise, smoke and dust hazards, cyanide and mercury poisoning, flammable and explosive gases and other substances poisoning, combustion and explosion hazards, and falling accidents from high places. According to the statistical analysis of previous accidents, illegal operation or misoperation, defects of equipment (facilities) and protective devices, lack of safety technical knowledge, lack of on-site inspection guidance, lack of monitoring measures, monitoring devices and personal protective equipment, and imperfect accident prevention and rescue measures.
