Unfortunately, yes they are necessary for legal reasons, not practical ones. As an educator of safety, I teach people about SDSs only because I have to. What they really need to understand is GHS. I personally feel that SDSs are useless for the lab chemist because of (even with GHS) inconsistency and statements that are too broad. But I also am sure to mention these downfalls of SDSs and discuss other ways of determining likely hazards of chemicals such as previous experience, chemical structure, reaction chemistry, and other resources such as Lange's, Bretherick's, and Sax's handbooks. My actual go-to safety resource that I refer to anytime I don‰??t recognize a chemical that has been requested is my old '92-'93 Aldrich catalog. Even the 2012-14 version of that catalog has GHS codes that have been reliable for everything I have searched thus far. So, for the little bit of what I get to them that they will actually keep with them, I prefer that they understand what th!
e GHS codes are telling them instead of interpretations of a combination of broad statements that will vary from one SDS to the next. Why have the focus be on a huge document that sometimes confuses me?
....my 2 cents...

I should have specified that I was thinking of the laboratory use case with inventories of more than 50 chemicals in laboratory scale containers when I posed the question. I also don't think of regulatory compliance as value added to the use of the chemical, but rather an adjunct to the use of the chemical. Given that the average penalty associated with a HazCom violation is $500, which is less than the cost of many chemicals, I'm looking for ways that the safety information can be best used to support better use of the chemical.

I'm not sure that SDS's are for employees - they are written by chemical safety experts and significant safety expertise is needed to parse and interpret the information on the SDS. My hope is to help lab workers understand the GHS labels proficiently and then work with them to use SDSs to help answer specific questions that they have after reviewing the label information.

There are many other barriers associated with an Internet search - cryptic search ranking mechanisms obscure valuable sites, web sites that hide information behind poorly named tabs, etc. However, I'm not sure acquisition of an SDS is the end goal of someone working with a chemical - I suspect that they want to be able to answer a question about the use of a chemical.

This is precisely why a significant amount of chemical safety expertise is need to use SDS's; I think that many safety people undersell their skills in dealing with these challenges when they suggest anyone working with a specific chemical should be able to deal with all of the safety information available for it.

I agree that many emergency responders ask for SDS's, but I don't think SDS are well suited as emergency planning documents.
As you said, since (M)SDS's have been around for 30+ years and the GHS for 5 years, I think it's time to consider whether their value are worth the investment or whether there are other approaches to supporting worker's right to know, right to understand and right to act.
Thanks to everyone for their comments on this. I'd be interested in what others think as well.
