Which statement best describes a local application system?

• A. It has a fixed supply permanently connected to fixed piping with nozzles discharging directly into the fire
• B. It uses water as an extinguishing agent
• C. It relies on portable CO2 cylinders to reach the fire
• D. It is a manual pump system without piping

Answer: (A)

A local application system is a fixed installation where the clean agent is stored in a permanent supply and delivered through fixed piping to discharge nozzles that target the fire directly. This setup focuses suppression at the source by directing the agent precisely where the fire is, rather than flooding the entire space or relying on portable equipment. It does not use water as the extinguishing agent, it doesn’t depend on portable CO2 cylinders, and it isn’t a manual pump system without piping. That fixed, pipe-delivered, nozzle-directed delivery matches the concept of local application best.
