I am working on our yearly chemical inventory and making labels so we will be in compliance with the GHS labeling.  I have three questions I don’t know the answers to:


1.        If I have multiple bottles of the same chemical, from different vendors, do I need SDS’s from each vendor?  And some of my bottles are really old, the vendors no longer exist, but the chemical is fine, so what SDS’s do I use for those?

2.       If I have a solution of say NaOH, that I made up myself, but keep around for months, I know it needs to have a GHS label. However, clearly a 0.10 M NaOH solution isn’t as hazardous as the solid is, and I have bottles of 5 or 6 different concentrations, from 0.10 M to 6.0 M, and they’d all have different hazards. The more dilute they are, the less dangerous, and the less requirement for PPE, so it doesn’t seem like they should have the same label, or SDS sheet.  If they don’t need to, where do I get the solution SDS’s and who’s name, address and phone number belongs on the label?  My name, because I made the solution, or the vendor of the solid I used to make the solution?

3.       Is there an inexpensive way to make the inventory, get the right SDS’s and print the GHS labels?


Thanks, feel free to email me directly, or to answer to the list serve.
