Refrigerant R134A Properties: Combustibility

WARNING: This page is about a different car, the 2023 Audi S3, 2023 Audi RS 3, 2023 Audi A3 Quattro, and 2023 Audi A3. However, it is still accessible from the selected car via links, so may be relevant.

Refrigerant is non-flammable. It actually has a fire-resistant or fire extinguishing effect. Refrigerant breaks down when exposed to flames or extremely hot surfaces. UV light (occurring for example during electric welding) also causes refrigerant decomposition. The resulting decomposition products are toxic and must not be inhaled. However, irritation of the mucous membranes provides an adequate and timely warning.
