3. Storage
New Refrigerant R-407C
R-407C are liquefied gases, and the High-Pressure Gas Safety Law must be observed in handling
them. Before using, refer to the High-Pressure Gas Safety Law.
The High-Pressure Gas Safety Law specifies standards and regulations that must be followed to
ensure the safe use of high-pressure gases. Be sure to follow the regulations to prevent accidents.
Since R-407C are high-pressure gases, they are contained in high-pressure vessels.
Although those vessels are durable and strong, careless handling can cause damage that can lead to
unexpected accidents. Do not drop cylinders, let them fall, apply impact or roll them on the ground.
Although R-407C are not flammable, they must be stored in a well-ventilated, cool and dark area in the
same way as any other high-pressure gases.
It should be noted that high-pressure vessels are equipped with safety devices that releases gas when
the ambient temperature reaches a certain level (fusible plug melts) and when the pressure exceeds a
certain level (spring-activated safety valve operates).
