Which of the following could be a consequence of not adhering to proper cargo handling procedures?

The correct choice is C, as failure to adhere to proper cargo handling procedures can lead directly to environmental contamination. Proper handling protocols are established to minimize the risk of spills, leaks, or accidental releases of hazardous materials during the loading and unloading processes. When these procedures are not followed, the likelihood of such incidents increases, which can have harmful consequences for the marine environment, wildlife, and surrounding communities.

While operational efficiency, safety measures, and cargo delivery time are important aspects of cargo handling, they are more likely to be enhanced through proper adherence to procedures. Ignoring established protocols can disrupt operations, result in safety risks, and potentially delay cargo delivery due to incidents that necessitate cleanup or other corrective measures. Hence, the consequence of environmental contamination stands out as a direct result of not following the necessary guidelines during cargo handling.
