What is the first step you should take in a critical incident over the radio?

In a critical incident, the first step in communication is to state the nature of the incident clearly and concisely. This is essential because it establishes a context and understanding for those who are responding to the situation. By articulating the incident right away, you enable others to assess the urgency and type of response needed, facilitating quicker and more effective action.

This initial communication sets the stage for all further actions, ensuring that everyone involved is on the same page regarding what is happening. Following this, additional details can be provided, such as requesting backup, sharing a history of the situation, or identifying parties involved, but the priority is always to convey the nature of the incident first. This clarity helps in orchestrating an effective response and enables resources to be allocated appropriately based on the needs of the situation.
