• B. Quarterly
• C. Annually
• D. Biannually

Answer: (C)

Dry chemical systems, which are crucial for fire suppression in airport environments, must be inspected on an annual basis according to FAA regulations. This requirement ensures that the systems remain operational and effective when needed. Regular annual inspections help identify any issues such as corrosion, discharge pressure, and the integrity of the system components, which can deteriorate over time due to various factors including environmental conditions and usage.

The emphasis on an annual inspection cycle aligns with best practices in fire safety management, where consistent checks are vital for maintaining readiness in case of an emergency. This regulation reflects the balance between ensuring adequate safety measures and managing the operational workload, facilitating airports in maintaining compliance without overwhelming resources.
