Someone is inside or may be injured
Give emergency responders the location and the information you already have about the occupants. Do not go back through a damaged area to make your report more complete. A partial report from safety is more useful than exposing another person. Describe any known wire involvement or blocked entrance so responders can consider those hazards as well.
Notice next: Stay available to provide information from the safe location responders direct you to use. Leave rescue and access decisions to them.
