What type of statements must labeling include to warn users about the chemical?

Labeling must include warning statements and precautionary statements to effectively inform users about the hazards associated with a chemical. This requirement is grounded in the principles of Hazard Communication, which aim to provide essential information about chemical hazards to ensure safe handling and use. Warning statements are critical as they clearly identify the potential risks a user might encounter, while precautionary statements give guidance on how to minimize those risks—such as safe handling procedures, storage recommendations, and personal protective equipment to use.

The inclusion of these specific types of statements on labels is crucial as it not only informs users of the dangers but also helps in preventing accidents and health issues related to hazardous substances. By understanding both the nature of the hazard and the necessary precautions, individuals can take appropriate measures to safeguard themselves and others around them.

This focus on warning and precautionary statements is mandated by regulations such as the OSHA Hazard Communication Standard, which emphasizes the importance of communicating information about hazardous chemicals in a clear and actionable manner.
