Help & FAQs ...
How’d you choose these chemicals?
Over 98% of the chemicals on the list have been seen in secondary schools in Washington State during both the King County and Washington State Rehab the Lab Projects. The others were listed as chemicals of concern in schools by the American Chemical Society.

What’s “Hazard Rank”?
Hazard rank is a short-hand quick assessment of comparative hazards. 0 is very low hazard and relatively safe for students to handle. 5 is extremely hazardous (physically &/or toxicologically) AND has little-to-no educational utility in primary or secondary schools.
What’s “Minimum Grade Level Restrictions” mean?
This is our attempt to provide recommendations for the minimum grade level curriculum that should use these chemicals. The rating is based on three factors: 1) the chemical’s comparative hazards, 2) if the chemical is sold by one of the three major chemical supply companies for schools (Flinn Scientific, Carolina Biological Supply or Sargent Welch), and 3) the frequency of use in experiments in specific grade-level chemistry. For instance, Acetic Anhydride is used in the manufacture of aspirin in Advanced Placement organic chemistry (AP Chem). AP Chem is college-credited curriculum taught to high school students.
What’s “Storage Category”?
If you click on the word “storage category” in the database, it will sort it alphabetically. What you’ll see is that chemicals with the same storage category share the same hazardous characteristics. It’s a system designed to keep incompatible chemicals away from each other. Categories preceded by the letter “O” are organic compounds, those with an “I” are inorganic.

Who’s the intended audience for the School Chemicals Database?
The intended audience is public and private primary & secondary school science teachers, risk managers and purchasing agents. However, the database is also a very useful tool for public health, safety and health, and environmental inspectors visiting any kind of laboratory. It is also useful for people wishing to know the hazards of one of the ingredients of a commercially available product.
