Subject: Re: [DCHAS-L] SDS concern

On a related note to this question- what's the best approach for determining the effect of modifications (i.e. dilution) to materials from the original SDS form? I don't have to do any official documentation, but I'm curious how to best approach this kind of situation for internal risk assessment.

Aniello:

The short answer is, "Yes, it is incorrect to provide an SDS that is not reflective of the stuff in the bottle." 29CFR1910.1200(g)(5) states in part:

"The chemical manufacturer, importer or employer preparing the safety data sheet shall ensure that the information provided accurately reflects the scientific evidence used in making the hazard classification."

There are a boatload of regulations contained in Appendices A and B of the Hazard Communication Standard and in the GHS "Purple Book" on how to determine the classification of the material. Appendix C of HAZCOM gives the required label hazard and precautionary statements as well as the required pictograms for the SDS.

Hi-

Please let me start to wish Monna Happy Birthday!!!!

My concern is the following. We run a Chemistry Outreach program to local high schools.We provide some different types of equipment and small quantities of chemical solutions to these sites. I was questioned today by an individual that came from industry and now is working in academia. The concern was that the SDS should reflect not only the chemical but the form it is in. For example, I prepared a 0.1M Magnesium Sulfate solution. I usually provide an SDS of Magnesium sulfate heptahydrate solid and not of the solution I prepared. Is that wrong? I researched OSHA and did not see anything in the language? Is there anything in the new GHS system? I could not find anything. I appreciate everyone's help and input.

Thanks,
