What must the first two officers who enter a room ensure?

The first two officers who enter a room during an active shooter scenario prioritize clearing the room for any possible threats because their immediate goal is to locate and neutralize the active threat to ensure the safety of themselves and any potential victims. The emphasis on clearing the room highlights the need for rapid assessment and action in a high-stakes situation where threats can be imminent and fluid.

Clearing the room regularly involves assessing for the presence of the shooter, any accomplices, or victims who may need assistance, while also being vigilant about their own safety. This essential task helps to minimize the risk to other individuals who may be hiding or injured, ensuring a swift resolution to the threat.

While securing a perimeter, securing weapons, and effective communication are all important aspects of incident response, the immediacy of clearing the room to confront or eliminate the threat takes precedence when lives are at risk. The primary concern of the first officers on the scene is to neutralize the danger as quickly as possible.
