What key elements are included in a chemical label?

Chemical labels play a critical role in communicating important safety information about hazardous substances. The correct choice highlights key elements that must be included on a chemical label to ensure safe handling and awareness of the associated risks.

The product identifier allows users to easily recognize the chemical being handled. Hazard symbols visually represent the specific dangers associated with the chemical, enabling quick recognition of the type of hazards present. The signal word indicates the severity of the hazard, using terms like "Danger" or "Warning" to effectively convey the urgency needed for caution. Hazard statements provide specific details about the nature of the hazards, while precautionary statements outline recommended safety measures and first-aid responses. Together, these elements work to inform users effectively, enhancing their understanding of how to safely handle the chemical and respond appropriately in case of an emergency.

While the other choices mention important information that can be relevant in various contexts, they do not capture the essential components specifically required by regulatory standards for chemical labeling, which are vital for safety and compliance in workplaces handling hazardous materials.
