What action must be taken during a red alert situation?

During a red alert situation, the primary concern is ensuring the safety and security of personnel. The correct action of seeking shelter inside is crucial, as a red alert typically indicates a potential or existing threat, such as severe weather, a security incident, or any other emergency that necessitates immediate protective measures.

In such situations, personnel must prioritize their safety by moving to designated safe areas, which are often located within structures that can provide protection from the elements or potential hazards. This practice helps to minimize exposure to danger, whether it be related to environmental conditions or security risks.

The other courses of action do not prioritize safety. Resuming ramp activity immediately disregards the potential threat and could place personnel at risk. Using hand signals for communication might be necessary in certain circumstances but does not address the urgent need for safety. Continuing operations as usual could lead to serious consequences if the threat is imminent and requires immediate action to protect those on-site.
