Introduction to the hazards of paint:
1, a large number of teratogenic research data confirmed that the toxic substances left in the house decoration can cause fertility deformity.
2. The large amount of benzene series (benzene, toluene, xylene) used in septic paint and decorative glue can damage hematopoietic function, cause blood diseases, and can cause cancer; induce leukemia.
3, allergic common polyester paint in the important component TDI is listed as a high-hazard class in the national standard GB5044-85. Induced rash, dizziness, decreased immunity, respiratory damage, asthma and other allergic reactions.
4, brain poisoning manifested as damage to the nervous system. Solvents in paint (commonly known as thinner materials) accumulate in the central nervous system for a long time, leading to damage to brain cells, causing chronic solvent poisoning syndrome, neuropsychiatric disorders and so on. Reduce children's intelligence.
What is the danger of paint?
The gas of paint is mainly organic solvent. For the toxicity of organic solvent, please refer to the information here:
1. Toxicity of organic solvents
If a person inhales a vapor of an organic solvent for a long time, it will cause chronic poisoning. However, if exposed to a high concentration of organic solvent vapor for a short period of time, there is a risk of acute poisoning. In industrial hygiene, the harm of organic solvents to the human body is closely related to the volatility of solvents. At normal temperatures, low volatility solvents are less likely to pose a hazard in air. Other factors related to human harm include solvent fat solubility, reactivity, impurities, ways and means of absorption by the human body, metabolic rate of the human body, accumulation, individual feelings and sensitivities, and length of exposure.
2. Ways to harm the human body
(1) Hazards caused by skin contact:
Organic solvent vapor can irritate the mucous membranes of the eyes and cause tears; contact with the skin can dissolve the skin oil and penetrate into the tissues, interfere with physiological functions, dehydration, and infect dirt and bacteria due to dry skin. The keratinization of the skin causes keratinization of the epidermis, which stimulates the epidermis to cause redness and bubbles. Solvent infiltration into the human body destroys blood cells and bone marrow.
(2) Hazards caused by respiratory organs:
After the organic solvent vapor is inhaled into the human body through the respiratory organs, people often develop anesthesia. After the inhalation of steam, most of the cells are managed to reach the lungs, and then transmitted to other organs via blood or lymph, causing various degrees of poisoning. Because the human alveolar area is more than ten times the body surface area, and the blood circulation rate is very fast, it often causes significant toxicity to the respiratory tract, nervous system, lung, kidney, blood and hematopoietic system, and the inherent machine solvent causes poisoning through the respiratory organs. Most valued.
(3) Hazards caused by digestive organs:
Organic solvents are mainly caused by digestion and management. They are caused by eating, smoking or finger smearing in a contaminated solvent vapor. The damage is caused by the oral cavity, the esophagus and the gastrointestinal tract, causing nausea and vomiting. The digestive system harms other organs.
3. Physiological effects on human health
The general symptoms of organic solvent poisoning are headache, fatigue, loss of appetite, dizziness, and the like. High concentration of acute poisoning inhibits the central nervous system, causing loss of consciousness and anesthesia, which initially causes excitement, lethargy, headache, dizziness, exhaustion, loss of appetite, loss of consciousness, etc.; chronic poisoning caused by low concentration of vapor affects Hematopoietic system such as platelets and red blood cells, bleeding in the nostrils, gums and subcutaneous tissue, causing anemia in the human body.
The effects of general organic solvents on human physiology are as follows:
(1) Damage to the nervous system:
(2) Damage to liver function:
(3) Damage to kidney function:
(4) Destruction of the hematopoietic system:
(5) For mucous membranes and skin irritation:
3. Ways to reduce or reduce paint hazards:
Workers who have been in contact with paint for a long time should wear masks and gloves during construction to avoid direct contact between the paint and the skin. It is not advisable to drink white wine because alcohol will prolong its residence time in the body and is extremely unhealthy for health; the workplace should maintain air circulation. Reduce its concentration in the air; usually eat more foods with high vitamin content, drink plenty of water.
