What information must be included on a chemical label?

The requirement for what must be included on a chemical label is clearly defined under the Hazard Communication Standard (HCS). A chemical label must provide essential details that ensure safe handling and understanding of the hazards associated with the chemical.

The correct choice involves the inclusion of the product identifier, which allows users to know exactly what the chemical is, alongside a signal word, which indicates the level of hazard (such as "Warning" or "Danger"). Hazard statements succinctly describe the nature of the hazards, while precautionary statements provide guidance on how to minimize risks associated with the chemical's use, storage, and disposal. Additionally, supplier information is necessary so that consumers or handlers can easily trace back to the manufacturer for safety data or further inquiries.

This comprehensive information is critical for ensuring safety in the workplace and prevents accidents or health issues arising from chemical exposure. The other options lack essential information that is crucial for the effective communication of hazards associated with chemicals.
