What organization establishes specifications for disposable refrigerant cylinders?

The organization responsible for establishing specifications for disposable refrigerant cylinders is the Department of Transportation (DOT). This is because the DOT regulates the transportation of hazardous materials, including refrigerants, and sets standards for the design and manufacture of pressure vessels and cylinders used in the transportation of these materials.

Since refrigerants are often transported in these cylinders, the DOT's regulations ensure that they are built to appropriate safety standards to prevent leaks and explosions. Specific requirements can include the materials used, pressure ratings, and labeling, all of which the DOT defines to promote safety during transport and handling.

Understanding this is crucial for technicians dealing with refrigerants, as adherence to DOT regulations ensures compliance with safety laws and protects both the technician and the environment during the disposal of refrigerant cylinders.
