What is the underlying purpose of the one plus one method in fireground operations?

The one plus one method in fireground operations is primarily focused on safety. This approach entails that for every firefighter who is assigned to an operation, there must be another individual who is either working with them or monitoring their activity. This practice ensures that no firefighter is operating alone, which inherently increases safety levels during potentially hazardous situations. By having a buddy system, it promotes immediate assistance in case of emergencies, enhances situational awareness, and helps maintain a standard of vigilance.

This method also creates a structure where personnel can account for each other, reducing the risks associated with isolation in dangerous environments. While it indirectly benefits efficiency, accountability, and communication, the core intention lies in ensuring that safety is prioritized on the fireground, emphasizing the need for teamwork and support in life-threatening scenarios.
