If you are looking for the SDS because you have the material in your current inventory, one might be tempted to simply use it up to eliminate the need to have the SDS.However, you still need to document your company's use of that material under .1020, Access to Employee Exposure and Medical Records, and the SDS is normally the easiest way to do that.A "harmless" chemical may later be found to cause cancer or other disease sometime in the future (asbestos is one good example).It is certainly to your corporation's legal benefit to be able to produce documentation showing that you had supplied all the protective equipment and procedures necessary according the SDS you had at the time.

However, be sure to carefully check the revision dates on your sheets to make sure there haven't been any changes/updates that you might otherwise overlook!For chemicals that were delivered after the HCS took effect but are no longer produced, you can try the distributor you purchased the material from or the manufacturer directly per the principle of "downstream flow".You may run into some issues if the material is no longer manufactured or has been reformulated, so some effort may be required.As long as you've made (this is our best guess) looking at a "de minimus" violation, i.e.one where OSHA might note it during an inspection but not assess a penalty.
