Let's talk about the harm caused by decoration.

What are the hazards in the process of interior decoration? What harm can it do to human body? Due to the different decoration materials, working tools and working environment used in indoor decoration, the types and intensities of hazard factors are different, mainly as follows: 1. Formaldehyde mainly exists in decorative materials made of urea-formaldehyde resin and phenolic resin, especially wood-based panels and adhesives. Decoration carpenters use these materials to assemble or bond by hand at work, and are exposed to higher concentration of formaldehyde without taking any protective measures. It is easy to cause headache, dizziness, allergic asthma and allergic purpura, and in severe cases, it can lead to the occurrence of tumors. 2. Benzene and its homologues include benzene, toluene, xylene and styrene. It mainly exists in decoration paints, additives and diluents of various paints and coatings, various adhesives, waterproof materials, etc. Variability, especially in summer. Acute poisoning mainly damages the central nervous system, ranging from dizziness, nausea, chest tightness and fatigue to coma and even death due to respiratory and circulatory failure. Long-term exposure to low concentrations of benzene will lead to chronic benzene poisoning, hematopoietic disorder and severe aplastic anemia or leukemia. 3. Ammonia mainly comes from concrete admixture used in building construction, especially the concrete antifreeze with urea and ammonia as the main raw materials added to concrete walls in winter construction, which is reduced to ammonia with the change of environmental factors such as temperature, leading to the increase of ammonia concentration in indoor air. In addition, the additives and brighteners used in furniture finishing contain ammonia water. Under this superposition condition, the short-term contact concentration of ammonia is relatively high, which is harmful to decorators. It mainly causes irritating damage to human respiratory tract, eyes and skin, causing tears, sore throat, cough, nausea and even dyspnea and pulmonary edema. 4. Radioactive substances-Radon mainly comes from stone decorative materials, such as granite, marble, gypsum, building ceramics, tiles, etc. Generally speaking, red, green and variegated granite stones are highly radioactive, such as azalea red and Indian red. Marble, most slate, dark series (including black, blue and brown in dark colors) and gray series granite have low radioactivity (such as mongolia black and Spanish beige). Long-term exposure to radiation and radioactive gas radon produced by radioactive nuclide decay in decorative materials such as granite and marble can affect the immune system and hematopoietic function of the body and even lead to lung cancer. 5. Dust mainly includes sawdust dust, cement dust, silica dust, gypsum dust, ceramic dust and organic dust. Inhalation of dust can cause pneumoconiosis, dust deposition and chronic inflammation of respiratory tract. 6. Noise and vibration In the decoration process, due to the use of high-noise equipment such as chainsaws, hammers, electric drills, planers and cutting saws, as well as the continuity of construction and personal awareness of occupational protection, decoration personnel are easily affected by high noise and local arm vibration. Decoration personnel are often exposed to strong noise and vibration, which will inevitably damage their health for a long time and affect their hearing system, immune system and nervous system. There are many harmful factors in the decoration process. If there is no protection or improper protection, it will cause all kinds of acute and chronic occupational poisoning, pneumoconiosis, tumor and noise deafness. Moreover, this part of the population is highly mobile, with weak awareness of protection, working long hours every day, and some decoration workers often stay at the decoration site, so the degree of harm they face is far greater than that of workers exposed to occupational hazards in some productive enterprises, and their health protection status is worrying. To this end, experts from the Municipal Center for Disease Control and Prevention reminded us to do a good job in labor protection for decoration personnel and protect their health. With the promulgation and implementation of the national mandatory standards for decorative materials, the harmful degree of decorative materials has been greatly reduced. In order to protect the health of decoration personnel, we should strengthen the protection from the following points: 1. When purchasing decoration materials, owners should give priority to new materials that are non-toxic or low-toxic and environmentally friendly, such as benzene-free coatings and low-formaldehyde synthetic boards. Decoration personnel should refuse to use unlabeled ingredients, Chinese instructions for use, hazard and protection instructions, and materials that are highly toxic and cannot be personally protected. 2. When decorating, open doors and windows to keep indoor ventilation. Unused paint, coatings, etc. Must be covered and stored to reduce volatilization. Wear work clothes, protective gloves and other health protection articles correctly at work. Wear a gas mask when painting, painting, waterproof treatment, etc. When grinding and cutting floor tiles or tiles, try to use wet methods and wear dust masks. Wear earplugs or earmuffs when doing noisy work. 3. It is forbidden to smoke, eat, rest and stay at the decoration site, and clean up the abandoned decoration materials in time. 4. Try to reduce the decoration work in high temperature season, because the release of harmful gases will increase with the increase of temperature; Shorten continuous working hours, arrange rest time appropriately, and breathe fresh air outside the house; You'd better take a bath after work. 5. Choose tools and equipment that have little impact on health. Such as chain saws, planers and cutting machines equipped with noise elimination devices and dust absorption devices. 6. Carry out occupational health examination at least once a year, especially those who are often exposed to benzene-containing substances or suspected high-radioactive stone materials should have regular blood analysis and testing, and bricklayers and carpenters who are exposed to dust should take X-ray chest films. 7. In case of poisoning due to accidents or high concentration of volatile toxic substances, the decoration personnel should leave the site immediately, move to fresh air, take off contaminated clothes, and rinse the skin with clean water. And go to the hospital for treatment in time. 8. Decoration personnel should learn more about the protection of occupational hazards and know some legal knowledge about safeguarding their rights and interests. Those who are employed by the decoration company should take the initiative to sign a labor contract with the decoration company before work, and specify the occupational hazards and protection in the labor contract for long-term preservation. In case of occupational hazards, the saved labor contract will be one of the important proof materials.
