R407A is an HFC blend that is suitable for use in low and medium temperature refrigeration applications, such as those used in commercial refrigeration. It is an ideal retrofit solution for many existing R404A systems, offering a substantially lower carbon footprint due to its lower GWP, and improved energy efficiency.

Precautions to be taken in handling:  Avoid inhalation of high concentrations of vapors. Atmospheric levels should be controlled in compliance with the occupational exposure limit. Atmospheric concentrations well below the occupational exposure limit can be achieved by good occupational hygiene practice. The vapor is heavier than air, high concentrations may be produced at low levels where general ventilation is poor, in such cases provide adequate ventilation or wear suitable respiratory protective equipment with positive air supply. Avoid contact with naked flames and hot surfaces as corrosive and very toxic decomposition products can be formed. Avoid contact between the liquid and skin and eyes.
