R449A is a pressurized liquefied gas (UN 3161). Although A1 non-flammable, ensure adequate ventilation to prevent oxygen displacement in confined spaces. Do not invert or expose cylinders to sunlight.
| Storage & Transportation | Store in a cool, well-ventilated warehouse away from fire and heat; temperature not above 52℃. Keep separated from oxidizers and acids. Cylinders must be periodically inspected. |
