School is back in session and excitement is high. Teachers are always looking for new ways to make class more compelling, and the chemistry lab has some of the most thrilling projects.

Elephant toothpaste, dry ice, borax, and several other experiments require the safe storage and refrigeration of chemicals. While these projects are fun in the classroom under close supervision, it’s important to be aware of the potentially dangerous materials surrounding you.

Never store chemicals in the same place as food and drinks.

Even if the chemicals and their containers appear to be clean, it is possible for toxic fumes and materials to be lingering. A refrigerator that has housed chemicals should not contain anything that someone will ingest later.

Leave the lunches outside of the chemistry lab to keep everyone safe and be sure to keep an up-to-date inventory on all chemicals that includes expiration dates.

Have a great school year, and be safe!
