During foam proportioning tests, discharge foam solution shall be collected and disposed of by whom?

• A. The AHJ only
• B. Any of the occupants
• C. Only the installing contractor
• D. The owner, the owner's representative, or the installing contractor

Answer: (D)

During foam proportioning tests, the discharge must be collected and disposed of by the party responsible for the system installation and test execution—the owner, the owner's representative, or the installing contractor. This arrangement ensures proper control, accountability, and compliance with environmental and safety requirements, since foam concentrates and their additives can affect drainage, water quality, and nearby environments. The AHJ may witness and approve the test, but the actual disposal is managed by the entity carrying out or overseeing the work, not by occupants. While the installing contractor often handles the physical disposal, the owner or the owner's representative may authorize or oversee it under the project scope.
