- Appendix AWaste Minimization Checklist
This guide explains how you can minimize the hazardous wastes and other chemical pollution generated by experiments that are performed in classroom laboratories. It is intended for middle school, high school, and college science teachers.
Specifically, this guide will help you
This guide deals primarily with chemicals that will be used in a chemistry or biology laboratory in an educational institution. It does not deal with radioactive materials.
- Generate less waste and pollution and save money by purchasing chemicals effectively.
- Substitute safer chemicals for hazardous chemicals.
- Deal with a large inventory of mislabeled or unlabeled chemicals that were left by another teacher.
- Communicate the importance of waste minimization to school administrators.
- Recycle chemicals.
- Teach students environmental responsibility as you teach them to perform experiments.
The guidance presented is just thatguidance. Weigh it against other factors and always follow your good judgment; prudent safety practices; federal, state, and local laws and regulations; and school policies.
Because this guide is intended for teachers ranging from middle school to college, some of the guidelines we present may not apply to you. For example, guidance to substitute cyclohexane for benzene would be irrelevant to a middle school science teacher, whose students would never use a substance as hazardous as benzene. Similarly, a high school teacher might not have access to the resources needed to obtain the equipment necessary to do microscale experiments. If a guideline doesnt apply to you, it may give you other ideas. If you feel a guideline may be very helpful but you do not have the resources to implement it, you may want to approach your administration and request the necessary resources.
We realize that, as a teacher, you are subject to many pressures. We dont want waste minimization and pollution prevention to become another burden. It is our intention that this guide will provide you with information to help you deal with important waste minimization issues in the easiest manner possible. In fact, you should find that minimizing waste will simplify other jobs that you currently perform, such as disposing of chemicals and dealing with excess inventory.
