How often do SDS’s need to be updated for ISO 14001? I have heard its either yearly or as necessary, but some searching also says every 3 years so I am unsure. This is for the NC,USA.
I run a quality assurance lab that deals with some Hazmat materials (resin, catalysts, mold cleaners/releases, acetone, etc) and am currently working on getting ISO 14001 certification.
There is no quantified requirement per the standard. I suggest referencing the manufacturer or standard database for the most current revision, then you don't have to keep up with it.
When writing work instructions state "see database for latest revision" or " reference manufacturer". One less headache for document control.
