What should I do if formaldehyde exceeds the standard and causes formaldehyde poisoning?
Formaldehyde poisoning refers to the phenomenon that the concentration of formaldehyde in indoor air exceeds the national standard limit, which has typical pathological manifestations in human body. Formaldehyde poisoning can be divided into three levels according to the degree of harm, namely mild, moderate and severe. Different indoor formaldehyde concentrations have different degrees of harm to people's health. Therefore, people should adopt scientific methods to treat formaldehyde according to indoor formaldehyde detection data and poisoning characteristics.
1. For those with mild poisoning, it is suggested to leave the indoor environment with excessive formaldehyde immediately and move to an open and ventilated environment. Rinse the whole body with plenty of water in time. And was with soapy water or 2% sodium bicarbonate solution. If you accidentally touch your eyes, please rinse with plenty of water.
2. Moderately poisoned people are allowed to inhale 0. 1% dilute ammonia water. In order to quickly remove the throat edema and lung water caused by poisoning, it is suggested to use enough glucocorticoid at the early stage of treatment.
3. If you accidentally come into contact with a certain amount of formaldehyde in a short time, you will find respiratory irritation. Both need to be observed for 2 days. It is necessary to avoid the aggravation of illness caused by activities.
4, through reasonable oxygen therapy, keep the respiratory tract unobstructed, give bronchospasm, defoamer, tracheotomy when necessary.
5, symptomatic treatment, prevention of infection, prevention and treatment of complications.
The above are several first-aid measures for formaldehyde poisoning. You can deal with it selectively according to the actual situation. How can we avoid formaldehyde poisoning?
How to prevent indoor formaldehyde poisoning?
1. In the early stage of decoration, the building materials should be purchased with environmental protection materials that meet the national standards.
Controlling indoor formaldehyde residue means reducing the possibility of formaldehyde poisoning from the source. Therefore, when choosing building materials in the early stage of decoration, we must choose environmentally friendly building materials, especially in the selection of wood-based panels. We must choose boards that meet the standards of environmental protection ten ring Standard and E 1 or above. In the selection of coatings and furniture, we must also ensure that the boards are environmentally friendly, at least without irritating smell and paint smell.
2. In the middle period of decoration, the decoration process should be properly controlled to avoid excessive use of blockboard as grass-roots modeling and glue paint.
Some car owners like luxurious and beautiful appearance. You know, the more luxurious and beautiful it is, the more auxiliary materials and plates are used, and the more natural formaldehyde remains. Therefore, in the middle of decoration, the use of plates should be minimized to avoid the formation of too many hidden sources of formaldehyde release. Try not to spray paint on site. Diluents in paint are mainly benzene and toluene, which are harmful.
3. In the later stage of renovation, strengthen ventilation, and green plants and activated carbon can be used.
By the end of the renovation, all the furniture had been finished. At this time, the initial treatment method is forced ventilation to disperse the smell. Ventilation of in addition to formaldehyde is a simple and practical method. However, ventilation alone is not enough. We should also take some effective measures to control formaldehyde pollution. For example, putting some green plants indoors, such as Dendrocalamus giganteus and Chlorophytum, can properly adsorb formaldehyde, but because of the limited adsorption area of green plants, it can only play an auxiliary role.
If prevention is done in the early stage of renovation, then indoor formaldehyde control is needed at this time after renovation.
The so-called indoor formaldehyde treatment, Bian Xiao here refers to the professional in addition to formaldehyde company using scientific methods and special products to treat both the symptoms and root causes of formaldehyde release. The indoor formaldehyde treatment method adopted by Shaanxi Xinjubang Environmental Protection Technology is its comprehensive solution in Li Meijing and in addition to formaldehyde. The core of this scheme is that the super-active nano photocatalyst in Li Meijing, which can be activated by indoor natural light, has the same effect as the double-effect photocatalyst in Li Meijing, which has the national patent * * *, and at the same time, the formaldehyde emission source is controlled to meet the standard. The principle of Li Meijing in addition to formaldehyde is as follows:
Nano-photocatalyst film is a nano-film layer formed on the surface and wall of furniture after nano-photocatalyst is atomized and sprayed. The mechanism of purifying and decomposing formaldehyde by this membrane is as follows:
