Teachers should carefully purchase and label chemicals for elementary classrooms. Before purchasing chemicals, teachers should obtain a material safety data sheet for each chemical and confirm with the science department head that chemicals are safe. When purchasing, teachers should buy generic chemicals in limited quantities and avoid anything with a National Fire Protection Association rating over 2. All chemicals must be clearly labeled with their name, manufacturer information, date received, hazard symbol, strength, and highlighted emergency instructions, and the label needs a protective coating.
