What is the purpose of performing a test squirt?

• A. To verify the discharge system is functioning
• B. To determine nozzle size
• C. To clean the nozzle
• D. To discharge the entire contents

Answer: (A)

The purpose of a test squirt is to verify the discharge system is functioning. By triggering a controlled release, you confirm the actuator operates, the piping and valves are intact, and the nozzle can deliver the extinguishing agent to the protected area as designed. This ensures the system will work when needed in a real fire, catching issues like blockages, leaks, or valve failures before an incident occurs. The test uses a small, controlled amount of agent to confirm operation without wasting the entire contents. It isn’t about determining nozzle size or cleaning the nozzle, and it isn’t intended to discharge all of the system’s contents.
