Dr. Wang Mingxuan
Chronic poisoning can occur in the human body from frequent, small inhalations of formaldehyde. Formaldehyde strongly irritates the respiratory tract, eyes, and skin. Inhaling high concentrations of formaldehyde vapor over a short period may cause breathing difficulties and, in severe cases, lead to suffocation. Once formaldehyde poisoning occurs, the first step is to avoid exposure to the source of formaldehyde and to avoid staying for prolonged periods in enclosed environments. During treatment, the patient should walk on their own and be moved to a well-ventilated area. If the patient is unable to walk normally, they must be immediately transferred to a hospital.
