Final answer:
When a supplier label is unreadable, it must be replaced to maintain safety standards and ensure safe handling of the product.
Step-by-step explanation:
If a supplier label becomes damaged and unreadable, the correct action is to have it replaced. Supplier labels contain important information about the product, such as instructions for safe handling, risks associated with the product, and emergency contact information. These labels are crucial for maintaining safety standards in a work or educational environment, especially when dealing with potentially hazardous materials. Ignoring the damaged label or leaving it as is could lead to unsafe handling and accidents. Reporting to the authorities may be necessary if there is a wider issue with label quality or if the supplier fails to provide the required information.
