What is a product safety sign or label?

A product safety sign or label is primarily an identifier that provides critical safety information regarding the product. This type of label typically includes warnings, instructions, and other essential data that inform users about safe and proper use, potential hazards, and necessary precautions to take. The purpose of such labeling is to help prevent accidents and injuries during the use of the product, thereby enhancing the overall safety for the consumer.

In contrast, the other options do not fulfill this role. A decorative sticker on a product serves purely an aesthetic purpose and does not convey safety-related information. A warranty identifier is associated with the product's guarantee or service coverage rather than safety details, while a price tag simply provides pricing information without addressing safety concerns. Each of these alternatives lacks the primary function of a safety sign or label, which is to communicate necessary safety information effectively.
