What are the hazards in the top 10 high incidence industries of occupational diseases

1. What are the occupational hazards of titanium electrode forging operation

the main occupational hazards of forging operation are high temperature and thermal radiation. The old forging furnace is open type, the temperature can reach 800 ~ 900 ℃, and it is harmful. The heating furnace, which is now widely used, is closed and in good condition. However, when the furnace door is opened, the heat radiation intensity is also high when the forgings are put in or taken out. Carbon monoxide and sulfur dioxide are also produced in the forge, but in the well ventilated workshop, the concentration is generally not high. All kinds of hammers can produce strong noise and vibration. Forging operation is prone to equipment accident and scald, especially the injury caused by iron slag splashing during hammering2. What are the occupational hazards of heat treatment operation

the occupational hazard of heat treatment is high temperature, and all kinds of heating furnaces and salt baths are heat sources. When heating with high frequency, there will be high frequency electromagnetic field. Cyanide vapor can escape when cyanide bath is used. The vapor of benzene, toluene, methanol and other organic solvents can be released when organic solvents are used for gas carburizing

3. What are the occupational hazards in battery production

the main occupational hazards are lead smoke and lead dust. A large amount of lead dust can escape from lead melting, shot casting and grid plate. A large amount of lead dust can fly from ball milling (especially in discharging, loading, unloading and mixing). A large amount of lead dust and lead smoke can also be produced from coating, repairing and welding. Plate forming is to put the dried lead plate into the sulfuric acid forming tank with a specific gravity of 1.05-1.15 for charging, resulting in sulfuric acid mist. Lead melting, casting and plate drying have high temperature and heat radiation< What are the occupational hazards in the production of titanium electrode paint? the main occupational hazard in the production of titanium electrode paint is the inhalation of various solvent vapors, of which benzene is the most toxic. 1n the production of leaded paint, there are lead dust habits in the process of weighing, mixing and feeding, and irritating smoke and harmful gases (such as phenols and aldehydes) are produced in the boiling of hard resin and vegetable oil. Raw lacquer, phenolic resin, epoxy resin, solvent and grease can cause dermatitis 5. What are the occupational hazards of phosphate fertilizer production common phosphate fertilizers include phosphate rock powder, superphosphate, heavy superphosphate, calcium magnesium phosphate, etc., which are usually made from phosphate ore. A large amount of phosphorus containing dust is produced in crushing, ball milling and sieving of phosphorus ore, which can stimulate skin to produce dermatitis, eczema and chaps. Phosphate rock contains about. 7% fluoride. 1t can produce a lot of hydrogen fluoride, silicon tetrafluoride and sulfur dioxide in the process of mixing, forming, melting and discharging. 1t can cause upper respiratory tract irritation and chronic fluorosis. There is high temperature in heating stirring and melting of blast furnace 6. What are the occupational hazards in garment processing garment processing mainly includes three processes: cutting, sewing and ironing, and batch production mostly adopts flow process. The more dense the sewing machine, the stronger the noise. 1f a sewing worker keeps a forward posture for a long time, he may suffer from lumbago and leg pain. 1f the ironer holds the iron in hand for a long time, the right limb may ache, and the elderly may even have wrist tenosynovitis, scapulohumeral periarthritis, cervical spondylosis, etc. 1f the illumination is not enough, the vision will be affected 7. What are the occupational hazards in titanium electrode printing industry. The basic production process includes lead melting, typecasting, typesetting, paper molding, plate casting, plate repairing, copper plating or chromium plating, machine printing, binding, etc. Lead smoke is produced in lead melting, plate casting and lettering printing inks usually use benzene, toluene, xylene and gasoline as diluents, or used to wash the layout and cots, whose vapor can pollute the air in the workshop. There is noise in the wheel printing machine many chemicals such as phenol, formaldehyde, m-cresol, glacial acetic acid, phosphorus oxychloride, ammonia, benzaldehyde, ethyl acetate and alum chloride are used in lithography and gravure printing to stimulate corrosion< What are the occupational hazards in cotton textile industry? The basic production processes of cotton spinning and weaving include opening, blending, cleaning, carding, drawing, roving, spinning, warping, sizing, heald reeding and weaving. Cotton dust is produced in opening, mixing, cleaning and carding, and it can cause cotton dust disease by inhaling cotton dust. Many processes produce noise, and the weaving workshop has the most noise. 1f the textile workshop does not take heatstroke prevention measures in summer, strong solar radiation acts on the roof and walls, it can also form a high temperature and high humidity environment. There are a lot of work in the textile factory, if the lighting does not meet the requirements, it can cause eyesight fatigue and myopia. 1n addition, textile workers walk back and forth and stand more, not only labor-intensive, but also prone to flatfoot, varicose veins and other diseases the production process of wool textile industry is basically the same as that of cotton textile industry, but the raw wool may contain Bacillus anthracis and Brucella, so attention must be paid to disinfection 9. What occupational hazards exist in the electronic industry the electronic industry mainly involves the production and assembly of semiconductors, integrated circuits and electronic components. There are many kinds of poisons, such as carbon tetrachloride, benzene, trichloroethylene, acids, cyclohexanone, propanone, lead, etc. in addition, there are also harmful factors such as noise, dust, high frequency, ionizing radiation, etc< What are the occupational hazards in foundry operation? dust is the main occupational hazard in foundry operation. Dust is produced in grinding, sand screening, sand mixing, molding, unpacking, sand cleaning, noise spraying, sand coating and sand shell elimination in sand casting. Long term inhalation of foundry dust can cause pneumoconiosis. Melting furnace, molten metal and hot casting are all heat sources. Smelters and casting workers are affected by high temperature and strong heat radiation. Carbon monoxide and sulfur dioxide are produced during smelting and casting. Formaldehyde and ammonia can be produced when phenolic resin or urea formaldehyde resin is used as core binder. Wax casting can also produce a lot of ammonia. Zinc oxide dust is produced during brass casting, which causes casting heat after inhalation. Molding machine, tamping machine, noise sprayer, sanding machine, pneumatic tools and grinding wheel can produce noise and vibration copyright notice: This article is reproduced by 1nternet media, only representing the author’s point of view, and has nothing to do with this 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
