Is Freon harmful to humans?

Under normal circumstances, Freon is harmful to the human body. The specific analysis is as follows:

First, once Freon enters the body, it can replace oxygen atoms in the blood, reducing the blood's ability to transport oxygen and leading to tissue hypoxia and hypoxemia. In severe cases, hypercapnia may also occur. If exposed to large amounts of Freon gas, individuals should immediately move to an area with fresh air to prevent damage to the respiratory system. Second, Freon rapidly decomposes in the atmosphere, generating various toxic gases such as hydrochloric acid, chlorine, and carbon monoxide. Chlorine, in particular, is irritating to the respiratory system and may cause respiratory tract irritation. Individuals who inhale photodecomposed Freon may experience symptoms such as coughing, breathing difficulties, and dizziness. Additionally, Freon is a refrigerant; if the eyes or skin are exposed to Freon, cryogenic burns may occur, causing injury to the skin and eyes. Contact should be avoided promptly. Freon exposure may also trigger allergic reactions. It is recommended that individuals maintain a regular lifestyle, avoid staying up late, and engage in moderate daily physical exercise.
