The total volume of a storage tank according to building codes is equal to the volume multiplied by the storage pressure; what is the unit of measurement for storage pressure?

There is a dry hydrogen storage tank on the factory site, with a pressure of 8.0 MPa (absolute) and a volume of 22 m3. When installing this storage tank, what is the minimum distance required from it to industrial buildings with a fire resistance rating of Grade 1? Answer: The total volume of the storage tank is 22×8=176 m3; according to building codes, it should be 15 m3. Question: The answer given is 22×80=1760 – why is 80 used in the calculation?

When installing this storage tank, what is the minimum distance required from it to industrial buildings with a fire resistance rating of Grade 1? Answer: The total volume of the storage tank is 22×8=176 m3; according to building codes, it should be 12 m3. Question: The answer given is 22×80=1760 – why is 80 used in the calculation?
This volume is essentially standard; temperature is not taken into account, only pressure, and it is a rough calculation. So, the pressure is set at 80; the unit is bar, but it can be simply understood as atmospheric pressure.
Could you tell me where in the building codes it is specified that this unit is in bars? I couldn’t find it……
The specifications are clear, and the notes are very explicit
