In recent years, as people pay more and more attention to health, many painters are also worried that the poorly designed painting workshop will cause them to suffer from occupational diseases, so many companies are faced with the problem of recruiting people. If we want to solve this problem, our business managers must first understand the main hazards of the paint shop, what measures should be taken to manage, and how to let the shop workers know how to protect themselves. Today, Chuangzhi Coating will introduce it to you.

1. What are the main hazards in the paint shop?
As everyone in the industry knows, the main hazardous materials in the paint shop are divided into three categories, including waste gas, waste water and waste residue. Among them, the exhaust gas is a major threat to the staff and production safety of the paint shop. Because it will form paint mist, organic solvent vapor and dust during the spraying process, long-term exposure and inhalation of the operator can cause chronic poisoning and damage health. If they are discharged outdoors, it will cause air pollution. Some photochemically reactive solvents can form more toxic substances after being exposed to ultraviolet rays in sunlight, causing pollution.

In addition to the three wastes mentioned above, the main hazard in the paint shop is the paint used in the spraying process. The toxicity of paints is mainly caused by toxic substances such as solvents, pigments and some of them. Organic solvents are generally fat-soluble (good solubility for oils and fats). Therefore, when the solvent enters the human body, it can quickly interact with fatty substances, especially the nerve tissue, causing paralysis, action and language barriers. When organic solvents enter the human body, they can quickly interact with fatty substances, especially paralyzing nerve tissues, causing action and language barriers.

The toxicity of organic solvents to the nervous system is common, but due to different chemical structures, various organic solvents have their own personality and toxicity. The toxic solvents are mainly benzene, tetrachloroethane, isocyanate and the like. Taking benzene as an example, long-term work in an environment where the concentration of benzene is 100-300 mg may result in chronic poisoning of a different degree. Among them, benzene poisoning can be divided into the following three cases:

(1.) Mild benzene poisoning: may have headache, dizziness, general weakness, fatigue, lethargy, palpitations and loss of appetite, occasionally nosebleeds and bleeding gums.

(2.) Moderate benzene poisoning: white blood cells fall below 3000, red blood cells and thrombocytopenia, nasal and gum bleeding frequently, bruising and purple spots appear under the skin, women's menstrual period is prolonged, and resistance is decreased.

(3.) Severe benzene poisoning: white blood cells fall below 2000, red blood cells and platelets are greatly reduced, oral mucosa and subcutaneous hemorrhage, extensive retinal hemorrhage, enlarged liver, significant changes in bone tissue, polyneuritis, and aplastic anemia.

In order to ensure the health of the operator, it is necessary to rely on exhaust and ventilation to reduce the concentration of solvent vapor in the air below the maximum allowable concentration, that is, a safe concentration that is not damaged for a long time. Some pigments (such as lead-containing pigments and compounds such as antimony, cadmium, and mercury) and anti-fungal agents (such as organic mercury and octahydroxyquinoline copper) used in wooden carts are harmful substances, which can cause poisoning reactions if inhaled. . Some base materials are also very toxic. 


For example, polyurethane lacquer contains free isocyanate, which can make the respiratory system allergic; organic amines contained in the ring resin coating may be dermatitis. Therefore, precautions must be taken when applying these coatings to prevent inhalation or contact.

2. How should workshop workers protect themselves?
(1.) Read the relevant technology carefully before using any paints and tools and follow the safety instructions.

(2.) When performing rust removal, grinding, spraying, etc., it is necessary to wear protective glasses and filter masks to prevent damage to the eyes and respiratory system such as gravel and paint mist. Acid-resistant gloves and goggles should be worn when pickling or rust removal. The use of bipartite coatings, especially those containing isocyanates, must be carried out in a spray booth with a sealed and well ventilated system. The operator must wear an activated carbon filter or a gas mask.

(3.) Ensure good circulation during indoor construction. When the painting operation is carried out in the painting booth, the exhaust system must be activated and continue to be activated for about 10 minutes after the spraying operation is completed to remove the spray and avoid the accumulation of solvent gas.

(4.) Protective overalls must be worn when handling and handling paint. Care must be taken when using toxic and hazardous paints and accessories. Do not expose the eyes, mouth and other exposed parts of the body. If there is any contact, wash it with plenty of water immediately and ask your doctor for treatment.

(5.) Clean paint and other flammable materials splashing on the ground at any time. After construction, the paint bucket should be closed, cleaning tools and paints should be cleaned; protective equipment should be kept in special order.

(6.) It is forbidden to smoke, eat or store beverages in the paint shop. After work, wash hands and face thoroughly before eating.
