What to do if formaldehyde exceeds the standard in kindergarten

If the formaldehyde level exceeds the standard in a kindergarten, it is quite serious. It will cause many children to suffer from formaldehyde poisoning. The treatment of formaldehyde poisoning is not yet perfect, so if it is found to exceed the standard, it must be dealt with in time. The first thing is to open the windows for ventilation. If necessary, you can also plant some plants in the room, which can also absorb formaldehyde.

1. Open windows for ventilation 2. Green plants absorb 3. Add activated carbon 4. Nano-photocatalytic technology: Use nano-photocatalytic decomposition of formaldehyde; Disadvantages: trace amount, little effect. 5. Masking technology (spraying, painting): Cover the pollution source; Disadvantages: The surface is good, but formaldehyde is still released slowly. 6. Oxidation technology: using strong oxidizing properties to decompose pollution; Disadvantage: toxic.

The above 6 methods each have their own advantages and disadvantages: 1) Green vegetation adsorption and window ventilation: characteristics, the processing capacity of green plants is too small, window opening is easy and is limited by climatic conditions. 2) Activated carbon adsorption technology: Adsorption materials made using microporous technology are used to adsorb chemical pollutants, and are very effective for formaldehyde and ammonia; Disadvantages: It is easy to become saturated in a short period of time, needs to be regenerated, and needs to be replaced frequently. 3) Nanotechnology catalytic technology works quickly and completely eliminates formaldehyde. Disadvantage: Requires professional formaldehyde removal personnel to operate.

1. Ventilation: because formaldehyde exists in three states: free, adsorbed and combined. Only free formaldehyde can be eliminated through ventilation. And it needs more than four times the normal wind speed to eliminate it. For formaldehyde inside furniture panels, the incubation period of its continuous release is as long as 3-15 years. Whether it is a new house or an old house, ventilation can only be a temporary solution and not a fundamental solution.

2. Add some tea leaves, grapefruit peels and plants. This effect is even worse. Because these things have limited adsorption capacity and effective adsorption capacity for toxic gases such as formaldehyde, they will not have much effect on slightly larger spaces. They only temporarily cover up the odor in the room and deceive everyone.

3. It is best to ask a professional management company to do a comprehensive management. Formulate different governance plans for different objects.

Formaldehyde, commonly known as formalin, is a colorless, irritating gas with a strong odor. Its 35% to 40% aqueous solution is commonly known as formalin. Formaldehyde is a protoplasmic poison that can bind to proteins. After inhaling high concentrations of formaldehyde, severe respiratory irritation and edema, eye stinging, headaches, and bronchial asthma may occur. Direct skin contact with formaldehyde can cause dermatitis, pigmentation, and necrosis.

Regular inhalation of small amounts of formaldehyde can cause chronic poisoning, resulting in mucosal congestion, skin irritation, allergic dermatitis, keratinization and brittle nails, and pain at the nail bed and fingertips. Long-term inhalation by pregnant women may cause malformations or even death in newborns. Long-term inhalation by men can lead to sperm deformity, death, and decreased sexual function. Severe cases can lead to leukemia, pneumothorax, and loss of reproductive ability. Systemic symptoms include headache, fatigue, poor appetite, palpitations, insomnia, weight loss, and autonomic nervous system disorders.
