What is the required agent quantity for ARFF vehicles serving aircraft in Index C?

• A. Less than Index B
• B. Equal to Index B
• C. Greater than Index B
• D. Independent of Index B

Answer: (C)

Index C classification for aircraft at airports is based on the size and capacity of the aircraft that may be operating in that area. The required agent quantity for ARFF (Aircraft Rescue and Firefighting) vehicles serving these aircraft is greater than that required for Index B. This is because Index C aircraft are typically larger and may pose a greater fire risk or require more resources to effectively control potential incidents.

ARFF vehicles must carry a sufficient amount of firefighting agent to adequately handle emergencies involving these larger aircraft. This ensures that in the event of an incident, the response team can quickly deploy enough firefighting agents to suppress fires and protect lives as well as property. The increased quantity requirement reflects the increased risks associated with larger aircraft, as the potential for more significant incidents or larger fires necessitates a more robust firefighting response.

In summary, the need for a greater quantity of firefighting agent for Index C is a direct response to the operational risks presented by larger aircraft, ensuring safety and effective incident management at airports.
