This depends on the rules of security in the working space.
because oxygen is combustible.
i think it is hazardous because it is not safe
All working conditions are potentially hazardous unless workers make them safe.
Every day, you breathe nitrogen and oxygen along with many other gases. Helium is inert and poses no threat at all except if you breathe only helium and you deprive yourself of oxygen. In theory, any gas can be breathed in small concentrations since the concentration is what determines hazardous effects. Even Oxygen can kill you if it is in too high of a concentration.
It is safe. More than 70% of the atmosphere is nitrogen
