What type of briefing is essential when standard safety briefings cannot be used?

An individual safety briefing is essential when standard safety briefings cannot be used, as it caters specifically to the needs and circumstances of an individual passenger or crew member. This type of briefing is crucial in situations where unique concerns, disabilities, or specific personal circumstances exist that require tailored information directly relevant to that person's safety.

In contrast to standard briefings, which deliver the same information to a larger group, an individual safety briefing allows for a more personal approach. It ensures that the individual understands safety procedures as they pertain to their specific situation, providing clarity on how to respond in emergencies and ensuring that essential information is conveyed directly to them.

This personalized method also offers the opportunity to answer questions and address any particular needs that may not be covered in a general briefing, enhancing the overall safety and preparedness of all individuals involved.
