How can crew members reassure passengers during a fire incident?

During a fire incident, it's essential for crew members to provide guidance that helps passengers remain as calm and safe as possible. Instructing passengers to breathe through clothing is a practical measure that can minimize inhalation of smoke and harmful gases, which is crucial for staying safe in a fire situation. This method can also help prevent panic among passengers, as it gives them a clear action to take in an emergency, signaling that there is a way to protect themselves even in a stressful situation.

Other options, although they may seem to offer assistance or reassurance, do not directly address the immediate dangers of a fire. Announcing an evacuation might be necessary at some point, but it can potentially create chaos and fear especially if passengers are not calm. Offering refreshments may be well-intentioned but is not relevant or useful during a fire emergency. Telling jokes could undermine the seriousness of the situation and might not be effective in helping passengers respond appropriately to the threat of fire.
