What should be included in the labeling of hazardous chemicals besides the name?

Labeling of hazardous chemicals is crucial for ensuring safety in environments where these substances are used or stored. The correct answer emphasizes the importance of including warning labels and hazard information on the labeling. This information provides essential details about the potential risks associated with the chemical, such as toxicity, flammability, or reactivity. It helps inform users of the necessary precautions to take while handling the substance, which is vital for preventing accidents and ensuring workplace safety.

Warning labels typically include symbols or pictograms that visually represent hazards, alongside clear text that describes the risks and recommended safety measures. This aligns with established regulatory standards, such as those outlined by the Occupational Safety and Health Administration (OSHA), which require specific hazard communication for chemicals used in workplaces. By highlighting these hazards, individuals can make informed decisions about how to properly work with and store hazardous materials, thus promoting a safer working environment.

In contrast, while the other options may contain relevant information in certain contexts, they do not prioritize the immediate safety implications that hazard information provides. The molecular weight, manufacturer's address, and price tag do not address the critical need for users to understand the risks associated with handling hazardous chemicals.
