Now that you know about the proper use of labels, here is a checklist for label compliance: Is there a person designated to ensure that newly received containers are labeled? Is there a person designated to ensure that containers are labeled as they are shipped out? Is there a periodic audit system in place to find and replace labels that have fallen off containers or that have become unreadable in use? Are all containers that are used by workers on different shifts properly labeled? Do workers understand the information contained on labels for the chemicals in their work areas?
