Under NYC fire code, refrigerant storage containers must be approved by which organization?

• A. US Department of Transportation
• B. EPA
• C. OSHA
• D. NFPA

Answer: (A)

Storage of refrigerants involves handling pressurized hazardous materials, so the containment must have official certification to ensure safety under both storage and potential transport conditions. Under NYC fire code, the organization responsible for approving refrigerant storage containers is the U.S. Department of Transportation. This means the containers are designed, tested, and marked to meet federal requirements for pressure resistance, containment, venting, and labeling, helping prevent leaks or ruptures in a storage area. The EPA regulates environmental aspects of refrigerants themselves, OSHA covers worker safety practices, and NFPA provides standards that the code may reference, but actual container approval comes from DOT. Look for DOT-approved markings on the cylinders and storage vessels as the sign of compliance.
