Safety & Precautions

Safety Notice

R22 is an HCFC controlled substance under the Montreal Protocol and its production is being phased down. It remains suitable for servicing existing equipment; new systems should consider low-GWP alternatives such as R32, R290 or HFOs.

Storage & Transportation	Store in a cool, well-ventilated warehouse away from fire and heat sources; temperature not above 52℃. Keep separated from oxidizers and acids. Cylinders must be periodically inspected; handle gently to avoid damage.
