Hazards involved with Oxygen Compressor buildings

[llls]

Hi,

I am looking at issues with oxygen compressor building. Recently came a across thsi problem:
The issue is the comp building is naturally ventilated via the roof apex opening (600 wide runs along the building roof). The interstage PSV and discharge PSV tail piping vents within the building and I am concern about the oxygen rich environment created during PSV lift or due to passing PSV etc.
Has any body seen this problem?

its a concern, they should be vented safely regardless of the gas
