What must be done before transporting hazardous materials?

Before transporting hazardous materials, ensuring compliance with regulations, proper labeling, and secure packaging is essential. This step is critical because it guarantees that the materials are handled according to federal, state, and local laws, which are designed to protect public safety and the environment.

Proper labeling communicates the nature of the hazards associated with the materials, facilitating appropriate responses in case of accidents. Secure packaging is necessary to prevent leaks or spills during transport, which can lead to dangerous situations for the public, emergency responders, and the environment.

The other options do not address the fundamental requirements needed for the safe and compliant transportation of hazardous materials. Posting on social media does not relate to the safe transport process, while shipping without proper documentation could result in legal penalties and increased risk during transit. Using the same packaging as non-hazardous materials fails to consider the specific requirements for hazardous items, which may differ significantly based on their nature and potential hazards.
