How many units are typically involved in the first phase of a high-rise response?

In a high-rise response, the first phase typically involves four units being deployed. This standard ensures that there is an adequate initial response force to effectively manage the complexities associated with high-rise emergencies. Each unit typically has a specific role, such as providing fire suppression, rapid intervention, search and rescue, and medical assistance.

The number of units is determined by protocols that recognize the unique challenges posed by high-rise buildings, including multiple access points, the need for coordinated vertical movement of personnel and equipment, and the potential for larger incidents that may require additional resources. The deployment of four units allows for a more comprehensive and efficient approach to managing the scene compared to a smaller number of units, which may not provide sufficient coverage for these tasks.
