In APCO 10-codes, 10-89 refers to "Bomb Threat."
This code is used by law enforcement or emergency services to indicate that there is a bomb threat at a particular location. When a unit communicates a 10-89, it usually means they are responding to or investigating a situation involving a reported bomb or explosive device.
For example, a communication might look like this:
- Unit 34: "Dispatch, this is Unit 34, we have a 10-89 at the city hall."
- Dispatcher: "Copy that, Unit 34. Units are being dispatched to assist."
Using 10-89 helps ensure that the seriousness of the situation is conveyed clearly, allowing for appropriate emergency protocols and resources to be mobilized.
