Footnotes to Appendix

Add the phrase BASED ON TEST WITH LABORATORY ANIMALS if only animal data are available to substantiate the chronic effect. 

If the foreseeable use of a corrosive chemical may involve the generation of a mist, is Avoid breathing mist an appropriate precautionary measure, or would a stronger direction be better Should a respirator be recommended If so, should a specific respirator he identified Perhaps engineering controls should be recommended. When such specific recommendations are made, have you accepted an unreasonable level of liability, or have you diminished your liability Judgment is required. If it is reasonably foreseeable that a nonhazardous chemical can be put to a surreptitious use, with the result that a different and hazardous chemical is produced, should that consequence be addressed on the label, or would such mention perhaps encourage such undesirable use  

Should a precautionary label address a foreseeable hazard that arises when a chemical is used in a plausible but unintended way—perhaps as one ingredient in a three component mixture that could result in a hazardous product For example, carbon, intended and labeled for use in an air purifying system can be mixed with potassium nitrate and sulfur to form Black Powder , a common explosive. Should a label address a foreseeable consequence that is minimally harmful but is extremely unpleasant To what extent should a label-constructor depend upon specialized knowledge possessed by an intended user of a chemical Clearly, judgment is required.
