What is the requirement for Index D in terms of fire response?

• A. Minimal vehicle and extinguisher capacity
• B. Increased water and agent capacity
• C. No special requirements
• D. Standard extinguishing agent application

Answer: (B)

Index D, which refers to a specific classification within the Airport/Heliport Planning and Design guidelines, requires an increased water and agent capacity for fire response. This is crucial because Index D typically pertains to airports with a higher risk of fire incidents due to factors such as larger aircraft or greater traffic levels.

The need for increased capacity ensures that fire response teams can manage larger and more severe fires that may occur. This encompasses having a sufficient supply of water, appropriate extinguishing agents, and the necessary equipment to effectively combat potential fire outbreaks. The enhanced capacity is instrumental for rapid and effective firefighting operations, reducing the risk of spread and ensuring the safety of both personnel and passengers.

Understanding this requirement reflects the importance of preparedness in airport settings, which deal with unique and often complex fire hazards associated with aerospace operations.
