While it may be very difficult to compile a list of chemicals that should 
be in a high school storeroom, it is much easier to create a list of 
chemicals to exclude of minimize. In my opinion, all of the chemicals on 
OSHA's Subpart Z list should be minimized or excluded. The Subpart Z list 
consists of the chemicals that OSHA considers to be confirmed as a cause 
of human health problems (mostly cancer). These conclusions have been 
created based upon the human epidemiological studies rather than just 
animal studies. Most of them have specific requirements for workers 
involved in the production, handling & use of these materials. The 
specific regulations can be accessed through the website shown below 
(29CFR Part 1910.1000-1096: 

All of the chemicals listed in Subpart Z require air monitoring to 
quantify the exposure levels, most of them require medical monitoring, & 
some of the chemicals require dedicated areas & systems with warning signs 
posted to segregate these areas. While OSHA's regulations do not cover 
students, I would think they would cover the instructors. But, regardless 
of the applicability of these regulations to a school setting, I believe 
there is no reason to expose the student, instructors, & other school 
employees to the potential health risk these materials can cause, 
especially if there is a less hazardous alternative available.

1910.1003       13 carcinogens including  4-nitrobiphenyl
1910.1004       alpha-Naphthylamine.
1910.1006       Methyl chloromethyl ether
1910.1007       3,3'-Dichlorobenzidine (& its salts)
1910.1008       bis-Chloromethyl ether
1910.1009       beta-Naphthylamine
1910.1010       Benzidine
1910.1011       4-Aminodiphenyl
1910.1012       Ethyleneimine
1910.1013       beta-Propiolactone
1910.1014       2-Acetylaminofluorene
1910.1015       4-Dimethylaminoazobenzene
1910.1016       N-Nitrosodimethylamine
1910.1017       Vinyl chloride
1910.1018       Inorganic arsenic (compounds)
1910.1025       Lead 
1910.1026       Chromium(VI) (compounds)
1910.1027       Cadmium (& compounds)
1910.1028       Benzene
1910.1044       1,2-Dibromo-2-chloropropane
1910.1045       Acrylonitrile
1910.1047       Ethylene oxide
1910.1048       Formaldehyde
1910.1050       Methylenedianiline
1910.1051       1,3-Butadiene
1910.1052       Methylene chloride

In my opinion, other chemicals to be wary of include those that form 
peroxides relatively quickly, are explosive or can be easily converted to 
explosives, are highly toxic, are named within the DEA regulation or are 
on the DEA Chemicals of Concern list. Some of these categories are due to 
lab safety issues, others are due to security/liability issues (how to 
keep the chemicals from being misappropriated for illegal uses).
