While there is information on chemicals that should not be used in high schools.  I believe that list is secondary to proper practices in the high school.
The teacher should plan the experiments and any demonstrations that he or she wants to do in the coming school year.  All those activities must be reviewed for safety as well as the educational value of each. If the quantities of chemicals used in the experiments can be scaled down to small scale or possibly microscale, then the teacher should consider that. Then, any list restricting chemicals should be consulted with an understanding of why each of the teacher's desired chemicals is on the list.  Finally, only sufficent quantities of chemicals for the coming year should be ordered.  Don't get tempted to order a kilogram of chemical if your need is for less than 100 grams.  Storage and disposal of chemicals must be considered.

With many thanks to everyone for their great answers to my "Fiesta Ware Lab" question, I now have another:

"Do you know of a list of chemicals that high schools should not have or use?"  [I guess he means from those commonly used in teaching Chemistry.]

A former student sent this question as he is teaching in a high school.  We teach a Chemical Lab Safety course, but the text was no help with this.  Thank you in advance for your help.
