Which document is essential for informing about hazardous chemicals?

The label is the essential document for informing about hazardous chemicals. It provides important information about the chemical’s identity, hazards, safe handling practices, and emergency measures. Labels typically include signal words, pictograms, and precautionary statements that indicate the nature of the hazards associated with the chemical, which is crucial for ensuring safety in environments where hazardous materials are present. By conveying this information in a clear and concise manner, labels help workers understand the risks and necessary precautions when handling these substances, ultimately promoting a safe working environment.

While notices, posters, and reports can provide additional information and awareness about hazardous chemicals, they do not fulfill the same foundational role that labels play in direct hazard communication. Labels are specifically designed to be immediately visible and are legally required on containers to help prevent accidents and ensure proper handling of chemicals.
