R134a, that is, 1,1,1,2-tetrafluoroethane, is widely used in many fields such as refrigeration. Its safety and operating specifications are related to the stability of production and use, and cannot be ignored.
From the perspective of physical and chemical characteristics, R134a is a colorless and odorless gas with relatively stable chemical properties. However, in high temperature or open flame environments, there is still a risk of decomposition, resulting in harmful hydrogen fluoride and other substances. Therefore, when storing and using, be sure to keep away from fire and high temperature heat sources.
When talking about storage specifications, it should be stored in a cool and well-ventilated place. The warehouse temperature should not be too high to prevent the container from breaking due to sudden pressure rise. At the same time, the storage area should be kept away from flammable and explosive items, and the storage container should be checked regularly. If there are signs of corrosion or damage, it must be dealt with immediately.
During the operation process, the use field needs to be well ventilated to prevent gas accumulation. Operators should wear appropriate protective equipment, such as gas masks, protective gloves, etc., to avoid gas contact with the skin and respiratory tract. During the filling process, operate strictly according to the specified pressure and filling amount, and must not overpressure or exceed.
