Dear Shailesh / Sagar, thanks for the attachments. Dear Dipil, thanks for the links.
Dear Rajendra,
What is important is to identify the hazards of the chemicals being used by you. To do this, refer to the MSDS, which would have defined the type of PPEs. Refer to the relevant IS code for those PPEs and procure them. Have your quality checkups as per the IS Code. This will serve your purpose.
Thanks & Regards,
Sudhir
