Deafness frequently observed in explosion victims, currently following terrorist attack, is a barrier to communication between victims and first responders. This may result in a delay in the initial triage and evacuation. In such situations, Paris Fire Brigade (Paris, France) proposes the use of assistance cards to help conscious, but deafened patients at the site of an attack where there may be numerous victims.
