Step-by-step explanation:
If you must decant a controlled product into a container that you keep around the workplace, you must affix a workplace label on it providing information in three areas. This is important because the workplace label provides essential information about the product, such as its hazards, precautions, and how to handle it safely. By placing a workplace label on the container, you ensure that everyone who comes into contact with the product is aware of its properties and can take the necessary precautions.
