What to Do in Case of Formaldehyde Poisoning

Formaldehyde poisoning can be managed through measures such as immediate removal from the contaminated environment, thorough cleansing of the skin and mucous membranes, maintaining airway patency, symptomatic and supportive treatment, and hospital observation and care. The specific management approach varies depending on the severity of poisoning; therefore, individuals experiencing suspicious symptoms—such as dizziness or sore throat—should seek medical attention promptly.

1. Removal from the contaminated environment: Upon recognizing signs of formaldehyde poisoning, immediately leave the formaldehyde-containing space and move to a well-ventilated outdoor area with fresh air. Cease further inhalation of the toxic gas, remove contaminated outer clothing, and minimize ongoing contact between the body and harmful substances. Do not remain in place—rapidly distance yourself from the contamination source to reduce continued toxin exposure and associated harm.

2. Cleansing of skin and mucous membranes: If the skin comes into direct contact with liquid formaldehyde, thoroughly rinse the affected area with running water. If eye irritation or tearing occurs, gently flush the eyes with clean water to reduce residual irritant effects. Avoid rubbing the eyes or surrounding skin. After rinsing, rest quietly and monitor whether skin or ocular discomfort improves.

3. Maintaining airway patency: Position the poisoned individual comfortably and loosen their collar to ensure unobstructed breathing. In cases of coughing or chest tightness, encourage quiet sitting rest and minimize physical activity to reduce oxygen demand. Monitor respiratory rhythm closely; if breathing becomes rapid or labored, do not administer food or drink, and await professional medical assistance.

4. Symptomatic and supportive management: For mild poisoning, after evacuation from the exposure site and thorough rinsing, rest adequately in a quiet environment while closely observing changes in symptoms such as dizziness or pharyngeal irritation. Do not self-administer medications indiscriminately. If discomfort persists or worsens, promptly visit a healthcare facility for professional evaluation and subsequent management.

5. Hospital observation and treatment: Moderate-to-severe formaldehyde poisoning requires hospital admission for comprehensive care. Healthcare providers will implement integrated interventions based on organ involvement, continuously monitor pulmonary, ocular, and other systemic functions, prevent delayed-onset injuries, and mitigate disease progression.

Prior to moving into a newly renovated home, ensure adequate ventilation by opening windows widely; minimize time spent in enclosed spaces; breathe fresh air regularly; routinely assess your own physical condition; and, whenever possible, avoid indoor environments with high formaldehyde concentrations.
