Chemicals should be stored in the manufacturer's container and labels should not be removed or defaced.
It is the responsibility of the laboratory professor/instructor to ensure that all secondary chemical containers are labeled correctly, i.e. chemical name, signal word, hazardous class, and date.
Chemical containers that will be used within one day and by the same person are exempt from the above requirement.
Hazardous waste containers are to be labeled accordingly. See Appendix F.
