What is the Tower exception for Second Alarm responses?

The Tower exception for Second Alarm responses indicates a specific operational protocol where the standard response is altered due to the unique circumstances associated with tower structures. In this context, indicating "2 EN instead of 3 EN" signifies that during a Second Alarm response specifically for tower incidents, only two engines are required instead of the usual three. This exception acknowledges the distinct logistical challenges and potential hazards presented by towers, which may not necessitate the full three-engine response typically deemed appropriate for other situations.

This adjusted requirement helps streamline emergency responses while ensuring that adequate resources remain available for other emergencies that may arise concurrently. Thus, the choice of "2 EN instead of 3 EN" reflects a strategic decision aimed at optimizing firefighting resources based on the specific needs of tower incidents.
