Does this belong to category three containers?

Does a vertical carbon dioxide storage tank with a volume of 80 M3 and a design pressure of 2.2 Mpa fall under category III containers?
It should be the medium-pressure storage container with PxV exceeding 10.
Class III pressure vessels are those that fall under one of the following categories: 1) High-pressure vessels； 2) Medium-pressure vessels (only for media with extremely high and high toxicity) ； 3) Medium-pressure storage vessels (only for flammable or moderately hazardous media with a pV product of 10 MPa·m3 or greater) ； 4) Medium-pressure reaction vessel (only for flammable or moderately hazardous media with a pV product of 0.5 Pa·m3 or greater) ； 5) Low-pressure vessels (only for media with extremely high or high toxicity levels, and a product of at least 0.2 MPa·m3) ； 6) High-pressure and medium-pressure shell-and-tube waste heat boilers ； 7) Medium-pressure glass-lined pressure vessels ； 8) Pressure vessels manufactured from materials with a high strength grade (meaning that the minimum specified value for tensile strength in the relevant standards is 540 MPa or higher) ； 9) Mobile pressure vessels, including railway tank cars (for liquefied gases and cryogenic liquids), tank trucks, and tank containers (for liquefied gases and cryogenic liquids), etc ； 10) Spherical storage tanks (volume greater than or equal to 50 m3) ； Low-temperature liquid storage containers (capacity greater than 5 m3). 11) Low-temperature liquid storage containers (with a volume greater than 5 m3): Give extra points if you think it’s useful; I’m poor, buddy!
Hehe, it should be three types of containers.
For simple book-flipping tasks, it’s better to do them by yourself
According to the old regulations, it should be a Class 2 container, as CO2 has ordinary properties. Non-toxic and non-flammable. New capacity regulation checklist decision.
First of all, carbon dioxide is not an extremely hazardous substance; it is not flammable, nor is it a liquefied gas – it can only be considered part of the second category of substances； Secondly, pv=1.76*10^5. It lies within the interval of Class II containers on the category classification diagram. So, I think it is a Class II container regardless of whether the new or old capacity regulations are applied.
Three categories of containers: 1. Medium-pressure containers containing media with extremely high or high toxicity, and low-pressure containers with P×V > 0.2 MPa·m3; 2. Medium-pressure reaction containers containing media with moderate flammability or toxicity and P×V > 0.5 MPa·m3, as well as medium-pressure storage containers with P×V > 10 MPa·m3; 3. High-pressure and medium-pressure shell-and-tube waste heat boilers; 4. High-pressure containers and ultra-high-pressure containers
