What kind of substances does the labeling requirement apply to?

The labeling requirement applies to all hazardous substances, which encompass a wide range of materials, including solids, liquids, and gases. This broad scope is critical for ensuring safety and awareness in various environments, such as workplaces and healthcare settings. By mandating that all hazardous substances are properly labeled, it ensures that individuals handling or potentially exposed to these materials are informed of the risks and can take appropriate precautions.

Labeling helps communicate essential information, such as the nature of the hazard, handling instructions, and first aid measures, thus playing a vital role in preventing accidents and ensuring compliance with safety regulations. This comprehensive approach to labeling is essential because hazards can exist in multiple forms, and individuals must be equipped with the right knowledge to manage these risks effectively.
