ARLINGTON, Va. — The U.S. Department of Transportation (DOT) Research and Special Programs Administration (RSPA) has released its final rule on refrigerant container shipment with changes sought by the Air-Conditioning and Refrigeration Institute (ARI) to avoid significant disruption in the transport of millions of cylinders.
In a rule issued May 8 titled “Hazardous Materials: Requirements for Maintenance, Re-qualification, Repair and Use of DOT Specification Cylinders,” the DOT amended the requirements for hazardous materials regulations applicable to the maintenance, requalification, repair, and use of DOT-specification cylinders issued on Aug. 8, 2002.
