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