Ralph, Re: "only a toxicologist:"   Tomorrow I'll be teaching a seminar in SDS reading for NYCOSH with an emphasis on Section 11.  And GHS gives you to tools to do that interpretation by mandating the category and signal words based on LD50s and other tests.  


The same nonsense is perpetrated about interpretation of the TLVs (as long as you also know the effects that the TLV was set to avoid). In my view, Industry forces toxicologists and ACGIH to say that this stuff is off limits to all but experts in order to throw up yet another road block to common sense evaluation of the relative safety of the products we use.

The way I see it, Industry's first line of defense against common sense is to fight any requirement to test chemicals for toxicity so there is no data to evaluate.  Once data is generated, they try keep people from seeing it, using it, or they confuse the meaning of the data with data they generate (See the book, Doubt is their Product, by David Michaels).   

Any SDS-educated worker can use tox and TLV data to good effect and should.  Power to the people.

>Replacement of hexanes with pentane. The neurological effects of n-hexanes are well known since 1960 through occupational studies

Good example. Another example of this discovery was related to auto mechanics in California.

Is this true? I often see toxicological data on Safety Data Sheets, which have a much broader audience than toxicologists.
