How often is dry-chemical system maintenance required to be serviced?

• A. Monthly
• B. Annually
• C. Bi-annually
• D. Quarterly

Answer: (B)

Dry-chemical fire suppression systems are critical components in airport firefighting, particularly because they are designed to extinguish flammable liquid fires and fires involving electrical equipment. The maintenance schedule for these systems is established based on industry standards, such as those set forth by the National Fire Protection Association (NFPA) and other regulatory bodies.

Annual servicing of dry-chemical fire suppression systems is essential to ensure optimal performance and compliance with safety regulations. This maintenance typically includes tasks such as inspecting the system for any signs of wear or damage, verifying that all components are functioning correctly, and refilling or replacing the dry chemical agent if necessary. Regular checks help to identify any issues that could prevent the system from operating effectively during an emergency.

While other maintenance frequencies like monthly, quarterly, or bi-annually are common for different types of fire suppression systems or components, they do not align with the specific requirements for dry-chemical systems. The annual maintenance provides a comprehensive checkup that balances thoroughness with pragmatic operational needs in an airport setting.
