What kind of information must the labels provide specifically?

Labels must provide specific information about the hazards associated with the chemicals they are marking. This is critical for ensuring safety in environments where hazardous materials are present. By clearly communicating the hazards, including health risks, flammability, and environmental dangers, labels enable workers and emergency responders to handle substances safely and appropriately.

The other choices do not align with the primary purpose of hazard communication. While product price, manufacturer location, and general product use might be relevant information in other contexts, they do not address the specific safety information that is essential for preventing accidents and ensuring proper handling of hazardous substances. Similarly, providing only the chemical compound name does not offer sufficient hazard information, as it is the specific hazards associated with that chemical that need to be communicated effectively on labels.
