To effectively label hazardous chemicals, which statement is required?

To effectively label hazardous chemicals, the inclusion of the GHS signal word is essential. The Globally Harmonized System (GHS) provides standardized communication regarding hazards, and the signal word is a significant part of that system. It typically falls into two categories: "Danger" for more severe hazards and "Warning" for less severe ones. The presence of a signal word immediately alerts users to the potential risks associated with the chemical, thus playing a crucial role in safety and risk management.

Labeling not only relies on signal words but also encompasses other elements like supplier names, usage instructions, and storage guidelines. However, the GHS signal word is foundational in indicating the level of hazard and ensuring users can quickly recognize the seriousness of the chemical's potential impact, thereby promoting safer handling and use.
