>What the PPE required in the lab?
>Is the safety shoes is mandatory inside the lab or not?
>Is the Helium and argon cylinders have to be outside the lab or not?
>Are there any special clothes need to be wear inside the lab?

These questions are best answered based on a risk assessment specific to the work being conducted. Resources to support such a risk assessment include:
1) The National Academy of Sciences publication "Prudent Practices in the Laboratory: Handling and Management of Chemical Hazards, Updated Version (2011)" at
2) The ACS document "Identifying and Evaluating Hazards in Research Laboratories" and accompanying web site at

Let me know if you have any questions about this.
