What is essential to ensure the safety of specimens during transport?

Using a biohazard leakproof container is essential for ensuring the safety of specimens during transport because it prevents contamination and protects both the specimens and the individuals handling them. This type of container is specifically designed to contain any potential leakage of biological materials, which is crucial for maintaining sample integrity and minimizing the risk of exposure to pathogens. When specimens are transported, they can be subject to various conditions that may cause them to leak or break. A leakproof container contributes significantly to biosafety measures, helping to protect healthcare workers, laboratory personnel, and the environment.

Labeling specimens, while important for identification and traceability, does not provide the physical containment necessary to ensure safety during transport. Cooling specimens in ice may be appropriate for certain types of samples but does not address the risk of biohazard exposure. Transporting specimens in a cardboard box lacks the specific safeguards needed for containing biological materials, making it an insufficient choice for ensuring overall safety in this context.
