The Williams Point & Shoot System includes both an air aspirating foam device designed to be installed on flammable liquid storage tanks for protection against a seal fire, as well as an optional fixed pipe to be used with a monitor and nozzle. The air aspirating Type II discharge device is installed above the roof joint and is mounted above the highest level of the floating roof. Foam solution is piped to the air aspirating device from outside the hazard area. For tanks with foam dams, the maximum recommended distance between discharge outlets is 240 ft (73.2 m).
