How many vehicles are required for an Index B classification?

An Index B classification is determined based on specific requirements pertaining to the size and type of incidents that can occur at an airport with that classification. Generally, an Index B classification indicates a facility that accommodates larger aircraft and involves a greater potential for significant fire-related emergencies.

The requirement for two vehicles reflects the need for adequate response capabilities in such scenarios. One vehicle alone may not be sufficient to handle the various challenges posed by incidents involving larger aircraft, which can include fires that spread more quickly and potential for hazardous materials. Therefore, having two vehicles ensures that an airport can provide an effective response, including the ability to attack the fire and protect surrounding areas, while also allowing for additional support and resources.

This redundancy not only enhances the safety of emergency responders but also significantly improves the level of service and preparedness in handling aircraft emergencies, which is a crucial responsibility of airport fire services. The standard for various classifications is designed to ensure sufficient resources are available to effectively manage the risks associated with different types of incidents at airports.
