Most Equipment with A2L Refrigerants can be Transported with Current Methods

Last week the Department of Transportation sent a letter of interpretation to the industry confirming manufacturers, distributors, and contractors can transport AC and refrigeration equipment over ground containing up to 25 pounds or 12 kg or A2L and A3 refrigerants without the need for HAZMAT protocols. This confirmation means most equipment using A2L refrigerants sold by distributors can be transported in the same manner as current equipment using A1 refrigerants. A2L refrigerants have a lower flammability rating and are non-toxic, A3 refrigerants have a higher flammability rating and include refrigerants such as propane.
