A minor Freon leak may not pose a health risk, but exposure to high amounts can cause harmful side effects, such as headaches, dizziness, heart palpitations, and irritation of the lungs, skin or eyes. Touching liquid Freon with bare skin may cause frostbite.
Freon leaking from an appliance rapidly converts to gas at room temperature, limiting exposure and health risks. A brand name for chemical refrigerants and pressurizers commonly used in air conditioners, refrigerators and spray cans in the past, the government regulates Freon's production and use due to its harmful effect on the ozone layer. Freon is more dangerous when it contaminates ground water or builds up in one area. Freon is sometimes directly inhaled for recreational drug use.
