I recommend the handbook "Prudent Practices in the Laboratory: Handling and Disposal of Chemicals" by the National Research Council published by National Academy Press. The book is focused on applying common sense safety measures in the laboratory for a variety of chemicals. The editors note that the MSDS documents are oriented to large quantities of chemical like those found in tankers or drums and that the protocols outlined are often unrealistic for the routine laboratory. They have guidelines for HF handling in the laboratory including a mini-safety summary and a chapter which has prudent safety practices for HF use. The whole focus of the book is toward the laboratory sized reagent containers and activity making it much more realistic than the MSDS is for daily use. Do not get me wrong, the MSDS should still be studied. However, if you followed those to a tee, you would have a bunny suit on and a fire hose every time you opened your 1 liter bottle of 2-propanol. The benefit of this book is that it is authoritative and perhaps it can help those doing battle with the abundant and sometimes very frustrating element administratium.

Thanks for the comments, you are exactly correct in your view.
Now if I could just convince non-chemist regulators of that, it would be a miracle...
They are taking the recommendations from the MSDS's and using those as absolute requirements regardless of how much chemical is used.
Were approaching the use of 1 ml of HF as requiring full body suit......
