Appendix C. Procedures for Storing Student Chemical Samples Between Lab Meetings

The ACC HazCom Program requires that all chemicals in secondary containers (this includes student samples) be labeled with:

• chemical name(s)
• physical and health hazards, including target organs

Below are the specific procedures that will be used to store student samples from one lab period to the next.

(1) The students will label their individual containers with their name, the instructor name, course number (e.g., CHEM 2423) and meeting time/day.

(2) The Science Lab Assistant will provide a large container (box, pan, bucket, etc.) in which to store all the samples from that section. This large container will be labeled with: (a) the experiment number, (b) the name(s) of the chemicals and (c) the health and physical hazards, including target organs.

(3) The Science Lab Assistant will make available a storage area for these chemicals, which may be: (a) a functioning fume hood, or (b) the chemical storeroom. In some instances, upon approval from the Safety Officer or Risk Management Office, student samples may be stored in the lab room.

Under no circumstances will chemicals be: (a) stored in student drawers or (b) stored without proper labeling.

(4) Once the student samples are no longer needed, the instructor will have the students properly dispose of the chemicals. The instructor or the Science Lab Assistant should promptly dispose of chemicals left by students who have dropped the course.
