When transferring a chemical to a different container, which of the following is NOT required on its label?

The correct choice highlights that an expiration date is not a required label element when transferring chemicals to a different container. This is relevant because chemical labeling primarily focuses on safety and identification for the handling and use of the substance.

When a chemical is transferred, the name of the chemical is crucial for clear identification, handling warnings are essential to inform about the potential dangers associated with the chemical, and instructions for use are important for ensuring the safe application of the product. However, while expiration dates can be important for certain products, particularly consumables or pharmaceuticals, they are not universally applicable for all chemicals, especially in the context of hazardous materials or industrial uses. Therefore, including an expiration date may not be necessary in every situation involving chemical transfer, allowing for a more flexible approach related to the chemical’s application and purpose.
