How harmful is R-134A on the skin?

Answer 1

R-134A (tetrafluoroethane) is generally considered to have low toxicity for skin exposure; however, it can cause irritation, dryness, or frostbite if it comes into contact with skin, especially in liquid form due to its low boiling point. Prolonged exposure may lead to more severe skin reactions. It's advisable to avoid direct contact and to handle it with protective gear when using it in applications such as refrigeration. If skin contact occurs, it’s important to wash the area with soap and water and seek medical attention if irritation persists.
