Dr. Li Jingli
Freon, commonly referring to chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), is a class of substances that were once widely used as refrigerants, foaming agents, and aerosol propellants. Their effects on health are mainly reflected in the following aspects:
1. Allergic reactions: Some individuals may experience skin allergies or irritation of the eyes and respiratory tract upon exposure to Freon, leading to symptoms such as itching, swelling, or difficulty breathing. However, these reactions typically occur only with direct and significant exposure.
2. Asphyxiation risk: If leaked in an enclosed space, Freon can displace oxygen in the air, causing oxygen deficiency and potentially leading to asphyxiation.
If you suspect you have been exposed to Freon or are experiencing related symptoms, leave the area immediately and seek medical assistance.
