Which of the following is true about hazardous materials?

Hazardous materials are indeed strictly regulated due to safety concerns, which is why this choice is the correct answer. The regulation of hazardous materials is vital to ensure the safety of workers, the environment, and the general public. These materials can pose significant risks, including chemical exposure, fires, explosions, and contamination. Consequently, various governmental and international regulations exist to control their handling, storage, transport, and disposal.

These regulations aim to mitigate risks associated with hazardous materials by establishing guidelines for proper labeling, packaging, and transportation practices. Compliance ensures that individuals and organizations minimize potential hazards and respond effectively in case of emergencies.

The other options reflect misconceptions about hazardous materials: they are not only relevant to shipping contexts, they are subject to environmental laws, and they require special handling during transportation to ensure safety.
