    The vast majority of coatings and solvents used in the coating workshop are toxic substances, forming paint mist, organic solvent vapor and dust in the work, operators long-term contact and inhalation of the body can cause chronic poisoning, harmful to health. If they are released outdoors, they can lead to air pollution, and some photochemically reactive solvents can form more toxic substances after exposure to ultraviolet light in the sun, causing public hazards.automobile repair enterprise's coating workshop is a three-dimensional operation, a higher degree of automaticity, the use of acid, alkali and other flammable coatings and other substances to deal with the coating if the operation is not proper, it is easy to occur personal and equipment accidents. In addition, in the coating process to produce exhaust gas, waste water and waste, such as "three waste", pollution of the environment. Therefore, the coating workshop is the factory's public hazard prevention and control focus and fire prevention key areas. Therefore, technicians and managers engaged in coating work must be fully familiar with coating safety and effective methods to control the occurrence of pollution and fire disasters. In the coating, because the materials used in the containing of harmful substances, so that the operator may suffer from acute or chronic poisoning, occupational diseases, skin diseases. It is therefore necessary to strengthen the protection of the working environment, labour protection and the health of workers.of these coatings is mainly caused by toxic substances such as solvents, pigments and some of their materials. Organic solvents are generally fat-soluble (good solubility for grease). Therefore, when solvents enter the human body can quickly and fat-containing substances, especially on nerve tissue paralysis, production and movement and language disorders. Organic solvents can act quickly with fatty substances after entering the body, especially in nerve tissue paralysis, movement and language disorders. The toxicity of organic solvents to the nervous system is common, but due to different chemical structures, various organic solvents also have their own personality, toxicity is not the same, of which toxic solvents are mainly benzene, tetrachloroethane, isocyanate lipids and so on. In the case of benzene, for example, long-term work in an environment with a concentration of 100-300 mg and m may produce a degree of chronic poisoning. Mild benzene poisoning: headache, dizziness, weakness, fatigue and drowsiness, palpitations and loss of appetite, and occasionally nosebleeds and bleeding gums. Moderate benzene poisoning: white blood cells dropped below 3000, red blood cells and plate plates decreased, nose, gums bleeding frequently, under the skin can appear bruising, purple spots, women's menstruation extended, resistance decreased. Severe benzene poisoning: white blood cells down to less than 2000, red blood cells and platelets significantly reduced, oral mucosa and epithelial bleeding, extensive retinal bleeding, swelling of the liver, significant changes in bone tissue, multiple neuritis, regenerative anemia and so on.in order to ensure the health of the operator, the concentration of solvent vapor in the air must be reduced by exhaust and breathing to below the maximum permitted concentration, i.e. the safe concentration that is not damaged for a long time. Some pigments (e.g. lead pigments and compounds such as palladium, cadmium, mercury, etc.) and mold inhibitors used in wooden cartons (e.g. organic mercury, octoxyhydroxyquine copper salts) are harmful substances that can cause a toxic reaction if inhaled into the body. Some substrates are also highly toxic, such as polyurethane paint containing free isocyanide, which can make the respiratory system allergic; The organic amine-like agent contained in the ring resin coating may be dermatitis, etc. In addition, in order to ensure the safety of the life of the coating staff, workers should also pay attention to the following: 1, before using any paint and tools should carefully read the relevant technology, and follow the relevant safety instructions.2, indoor construction should ensure good circulation. The exhaust system must be operated during the coating operation between the paint rooms and continue to operate for about 1min after the spraying work is complete in order to remove the spray and avoid the accumulation of solvent gases.3, protective work clothes must be worn when using and handling coatings. In rust removal, polishing, spraying and other work, must wear protective glasses, filter masks, to prevent gravel, paint fog and other damage to the eyes and respiratory system. Wear acid-resistant gloves and protective glasses when using acid wash to remove rust or lye to remove rust. The use of two-part coatings, especially those containing isocyanate, must be carried out in a sealed and well-ventilated paint room, and the operator must wear an activated carbon filter breathing mask or gas supply mask.4, when using toxic and harmful coatings and accessories, be careful not to make them contact with the eyes, mouth and other exposed parts of the body. If there is contact should be immediately washed with a large amount of water, and ask a doctor to deal with.5, it is prohibited to smoke, eat or store drinks in the coating workshop.6, after work, before eating must thoroughly wash hands and face.7, at any time to clean up the paint spilled on the ground and other flammable materials after the completion of construction should be closed paint barrels, cleaning tools and paint; Protective supplies should be specially kept without any contaminant materials and paper, etc. must be immediately placed in covered metal containers. 8, if you feel unwell, should report as soon as possible and ask a doctor to check.
