What is the second thing you must check in order to to report an AFFF "manned and ready"?

Explanation:
The key in declaring AFFF “manned and ready” is confirming there is enough concentrate available to operate the foam system reliably. The second thing you check is the foam concentrate level indicator (TLI) and confirm it reads about 95% or higher. A reading at 95% means the foam supply is near full, giving a solid safety margin and reducing the risk of running the system dry during a release. This specific level check directly verifies that the system has enough usable foam, which is essential for readiness. Other checks, like firemain pressure or whether the pump is running, are important parts of readiness, but the TLI at 95% specifically confirms you have enough foam on hand to sustain operations, making it the most critical second check for declaring the system ready.
