Upon detecting dangerous goods, what is the flight attendant's immediate action?

The appropriate immediate action for a flight attendant upon detecting dangerous goods is to classify the items involved. This step is crucial because identifying the nature of the items allows the flight attendant to assess the level of danger presented by the goods. Proper classification helps determine the necessary procedures to follow, including how to handle the situation and whether to alert the appropriate authorities or take additional safety measures.

Understanding the specific classification of dangerous goods can also guide the crew in making informed decisions about passenger safety, potential evacuation, and securing the hazardous items. This initial step is vital before taking further actions, as it sets the groundwork for a safe and effective response to the situation.

Continuing normal operations or alerting passengers prematurely without assessing the situation can lead to unnecessary panic or mishandling of potentially dangerous items. Checking inventory lists can provide context but does not directly address the immediate concern of classifying the threat.
