What is the purpose of labeling hazardous substances?

The primary purpose of labeling hazardous substances is to inform and alert handlers of potential dangers. Labels are critical for ensuring that anyone who comes into contact with the hazardous materials is aware of the risks involved, including physical hazards and health risks. This information is vital for the safe handling, transport, and storage of these substances, as it helps to prevent accidents and ensures that proper safety measures are taken.

Labels commonly include symbols, words, and instructions that clearly communicate what the substance is and the specific hazards it poses. This is essential not only for those directly handling the materials but also for emergency responders in case of spills or accidents. Effective labeling improves safety and compliance with regulatory requirements, such as those outlined in transportation safety laws, thereby protecting workers, the environment, and the public at large.

Other options do not serve the primary function of hazardous material labeling. For instance, entertainment is unrelated to safety, and obscuring the contents contradicts the principle of transparency required for safe handling. Compliance with international shipping rates, while a factor in global logistics, does not pertain to the function of warning about hazards associated with substances.
