A workplace label is not required if a transferred material is completely used over the course of the same work shift:

The statement is true because workplace labeling regulations often stipulate that labels are required for materials that are either stored or used over an extended period. If a transferred material is completely used within the same work shift, it falls under a practical exception to the labeling requirement. This is primarily because the risk of mishandling or misidentifying the material is significantly reduced when it is consumed or used in a single shift, thus minimizing the potential hazards associated with the material. Additionally, in fast-paced environments where materials are used immediately, the priority is on safety and efficiency, allowing for exemptions under specific conditions like this. This acknowledges that immediate use diminishes the likelihood of exposure or accidents related to unattended or improperly labeled materials.
