All foam systems must be discharged to pass an acceptance test.

All foam systems must be discharged to pass an acceptance test.

• A. False
• B. True
• C. Not required
• D. Depends

Answer: (A)

The key idea here is that acceptance testing for foam systems verifies that the system can operate as designed and deliver the foam solution at the correct proportions to the discharge devices. You don’t have to actually discharge foam from every foam system to pass every acceptance test. Some tests are done with water or test headers to confirm pumps, valves, proportioners, and flow paths work, and only certain tests require discharging foam to verify foam production and reach. So the blanket requirement that all foam systems must be discharged is not correct.
