Which action is essential in the embarkation process to prevent potential threats?

Conducting security screenings is a fundamental action in the embarkation process aimed at identifying and mitigating potential threats. This procedure involves systematically inspecting personnel, cargo, and equipment to ensure that no prohibited or dangerous items are being transported. By checking for explosives, weapons, or any hazardous materials, security screenings help safeguard the safety of all personnel involved and ensure the integrity of the operation.

In the broader context of embarkation, while actions such as loading materials in a specific order, checking weather conditions, and verifying load weight are also important for logistical efficiency and safety, they do not directly address the need to prevent threats. Security screenings are specifically designed to eliminate risks associated with threats, making this step a critical element in maintaining operational security during the embarkation process.
