When shipping refrigerants in hazard class 2.2 what information needs to be on the shipping paper?

• A. Number of cylinders of each gas
• B. Total weight
• C. Chemical names
• D. Temperature range

Answer: (A)

For Class 2.2 refrigerants, the quantity documented on the shipping paper is the number of cylinders of each gas. This packaging-unit quantity makes it clear how many containers are in the shipment, which is the most practical and enforceable way to gauge potential hazard and handle the load safely. Gas weights can vary with cylinder tare and different cylinder sizes, so listing the number of cylinders provides a consistent, easy-to-check measure for carriers and responders.

The shipping paper will also include the proper shipping name, hazard class, and UN number, but the exact quantity is expressed as cylinder count. Temperature range isn’t a required field for this purpose, and while chemical names are part of the description, they don’t convey the shipment’s quantity by themselves.
