What does the basis of the one plus one structure involve?

The concept of the one plus one structure primarily refers to the idea of having a corresponding apparatus for each engine company or line deployment. This structure is designed to ensure that there is an adequate and coordinated response capability in firefighting operations. It emphasizes the importance of not only having the necessary equipment but also ensuring that each engine company can operate effectively and safely with the appropriate resources available to them.

In scenarios where multiple line deployments are necessary, having a one-to-one relationship with apparatus allows for efficient and organized management of resources during incidents. This ensures that each crew has access to the right equipment and can mobilize quickly, which is crucial in emergency situations where time is of the essence. The structure supports enhanced safety and operational effectiveness by aligning personnel and equipment resources strategically.

Additionally, the principle supports a systematic approach to resource allocation, allowing command officers to plan and deploy units based on the scale of the incident. As teams engage with evolving emergencies, operational flexibility is maintained, fostering effective incident management and community safety.
