Mechanical processing industry, what mask to choose

Welding and gas cutting is an indispensable and important processing technology in modern industrial production and equipment maintenance. 1n mechanical processing industry, welding is a high-density operation, and the occupational hazards are very concentrated. As special operators, there is a lack of professional introduction on the understanding of respiratory hazards leading to occupational diseases and the selection of safe and effective respiratory protective equipment, Welder’s pneumoconiosis is very common in our country, and there are few channels for the majority of welding workers to understand the relevant knowledge. We hope that we can help welding workers to prevent the occupational hazards of welding smoke and choose safe and effective respiratory protective equipment< There are many kinds of harmful substances in welding operation, such as metal elements, welding flux and welding smoke under the action of high temperature flame, which endanger the health of workers. The most common occupational diseases are welder's pneumoconiosis and metal smoke heat. The main form of transmission is that welding smoke is inhaled into the lung, which is harmful to the health of workers< (1) metal smoke fever: the main symptoms are shivering after work, followed by fever, tiredness, metal smell in the mouth, nausea, itching throat, dyspnea, chest pain, loss of appetite, etc< (2) manganese poisoning is characterized by fatigue, headache, dizziness, drowsiness, poor memory and autonomic nerve dysfunction, such as slight tremor of tongue, eyelids and fingers, difficulty in turning and squatting toxic gas hazards (1) nitrogen oxides – have a stimulating effect on the lungs (2) ozone – have a strong stimulating effect on the human respiratory tract and lungs the respiratory protection of welders should be combined with the operation characteristics. When working in the open air, the harmful substances produced by welding will not gather in high concentration, and the harm is light; As the last line of defense to protect workers’ health, individual respiratory protection can not only be effective, in many cases, compared with ventilation facilities, the cost of personal protective equipment (such as welding gas mask, dust mask, such as Wuhan Longfei mask) is also lower our website solemnly declares that this article is reprinted by network media, only representing the author’s point of view, and has nothing to do with our website. 1f the information column articles and comments violate your legal rights, please call to let us know, and we will deal with them in time.
