Permanent Container Labels
No lab worker should use, store any hazardous substance in a laboratory if the container (including bags, barrels, bottles, boxes, cans, cylinders) does not meet the following labeling requirements in OSHA’s Hazard Communication standard (29 CFR 1910. 1200(F)(1):
Portable (Secondary) Container Labels
Often, laboratory operations require transferring chemicals from the original labeled container into a secondary container (e.g., beaker, flask, or bottle). Portable containers must comply with the labeling requirements listed above if any of the following events occur:
When a secondary container is used for longer than one shift or does not meet the requirement outlined in the permanent container labels section, above, a label needs to be applied to the secondary container. This label must contain two key pieces of information: the identity of the hazardous chemical (s) in the container (e.g., chemical name) and the hazards present.
Replacement Container Label
The existing label on a container entering the workplace from a supplier must not be removed, altered or defaced. If a chemical containers original label must be replaced, the new label must contain the same information as the original. Only use labels, ink and markings that are not soluble in the liquid content of the container.
