What is a critical step before transporting hazardous materials?

Ensuring proper labeling and documentation is essential before transporting hazardous materials because it helps communicate the potential risks associated with the materials being transported. Proper labeling includes displaying the correct hazard symbols and placards that indicate the type of hazardous material, ensuring that anyone handling or coming into proximity with the cargo is aware of the dangers. Documentation includes shipping papers and manifests that provide details about the contents, such as their nature, quantity, and any required safety measures.

This step is crucial for compliance with regulations set forth by various authorities, such as the Department of Transportation (DOT), and facilitates safe handling in the event of an emergency. Proper documentation and labeling foster a safer transportation environment by ensuring everyone involved is informed and prepared for potential hazards.
