ARLINGTON, Va. — The U.S. Department of Transportation's (DOT's) Research and Special Programs Administration (RSPA) has released its final rule on shipment of refrigerant cylinders with changes sought by the Air-Conditioning and Refrigeration Institute (ARI), which the association says will avoid disruption in the transport of cylinders.
In its rule (49 CFR 107, 171, 173, 177, and 180), titled "Hazardous Materials: Requirements for Maintenance, Requalification, Repair, and Use of DOT Specification Cylinders," the DOT amended the requirements for hazardous materials regulations applicable to DOT specification cylinders issued on August 8, 2002.
