summary

The severity of the signs of formaldehyde poisoning depends on the amount of formaldehyde inhaled or ingested by a person. How to correctly identify it in the earliest symptoms of formaldehyde poisoning. Formaldehyde (chemical formula HCHO, molecular weight: 30.03) is a colorless gas with strong pungent odor. It is soluble in water and alcohol ether. It is gaseous at room temperature, usually in the form of aqueous solution and gas. Acute formaldehyde poisoning is a systemic disease mainly caused by exposure to high concentration of formaldehyde vapor. Symptoms of formaldehyde allergy? Let's talk about it

Symptoms of formaldehyde allergy

The symptoms were transient eye and upper respiratory tract irritation, such as eye irritation, tears, sore throat, chest tightness, cough, etc. The symptoms included blurred vision, dizziness, headache and fatigue,

Persistent cough, hoarseness, chest pain, dyspnea, scattered patchy or patchy shadow on chest X-ray examination. After a large amount of formaldehyde vapor was inhaled in a short time, the patients with upper respiratory tract irritation reaction should be observed for at least 24 hours to avoid aggravating the disease after activity.

Mild and moderate poisoning, after short-term rest treatment, can be generally engaged in the original work after cure. But those with allergic constitution and severe poisoning should be transferred after cure. Physical examination should be carried out in the Department of internal medicine, ENT, dermatology, chest X-ray fluoroscopy or film reduction and other relevant examinations. If possible, the lung function can be measured.

matters needing attention

The ventilation method does not need to be explained too much. It is a simple and effective method to exhaust harmful gases to the outside through the flow of air. The disadvantage is that the formaldehyde release cycle is long, generally three to 15 years. It is obviously unrealistic to leave the new house idle for more than three years after decoration. Therefore, ventilation alone can not meet the requirements.
