What are reusable refrigeration containers known as?

Reusable refrigeration containers are specifically identified as DOT-49 containers according to the Department of Transportation (DOT) regulations. These containers are designed to be durable and capable of withstanding the conditions associated with transporting refrigerated materials. They comply with safety standards required for packaging, handling, and transporting hazardous materials under the DOT's specifications.

Understanding the correct designation helps ensure that refrigeration operating engineers are familiar with the types of containers used in their industry, promoting safety and compliance with regulatory requirements. The other designations, such as DOT-39, DOT-32, and DOT-80, refer to different types of containers or specifications that may not be suited for refrigeration or hazardous materials in the same context, emphasizing the importance of recognizing the specific application for which DOT-49 containers are intended.
