10-33: Emergency! All units stand by

In APCO 10-codes, 10-33 refers to "Emergency! All units stand by."

This code is used by law enforcement to indicate that there is an emergency situation that requires immediate attention and that all other units should hold off on non-emergency communications. It is a way to prioritize communication during critical incidents, ensuring that important information can be relayed without interference.

For example:

  • Officer: "Dispatch, we have a 10-33 situation at the intersection of 1st and Elm."
  • Dispatcher: "All units, be advised, we have a 10-33 in progress. Stand by for further instructions."

The use of 10-33 helps manage radio traffic and ensures that all available resources can be directed to the emergency at hand. This code is crucial for effective coordination and response during high-pressure scenarios.
