Skin or eye contact with fluorocarbon refrigerants can lead to irritation and frostbite. This is primarily due to the extremely low temperatures of these substances, which can cause the skin or tissues of the eye to freeze almost instantaneously upon contact. Frostbite occurs when the skin and underlying tissues freeze, leading to damage and potential necrosis if not treated promptly. In addition to frostbite, irritation can manifest as redness, swelling, pain, or a burning sensation, depending on the length and severity of the exposure.

The other choices do not accurately reflect the typical effects of contact with fluorocarbon refrigerants. Severe allergic reactions are not commonly associated with these substances in the context of contact; instead, they are more likely to cause physical damage due to temperature. Instantaneous evaporation describes the behavior of some refrigerants upon exposure to air but does not represent a consequence of direct skin or eye contact. Heat generation is not a relevant factor when discussing the effects of cold refrigerant contact, as these substances are typically used for their cooling properties.
