It is important to know portable containers must be under the positive control of the employee using it. If the employee walks away from the container and loses control of the chemical, it must be labeled as a workplace/secondary container.
Portable containers are used to transfer hazardous chemicals from labeled containers, and are intended only for the immediate use of the employee who performs the transfer. The employer is not required to label portable containers into which hazardous chemicals are transferred from labeled containers, and which are intended only for the immediate use of the employee who performs the transfer.
Drugs which are dispensed by a pharmacy to a health care provider for direct administration to a patient are exempted from labeling.
