2.5.2.3 Pneumatic Conveyors
2.5.2.3.1 Do not penetrate MFL fire walls with pneumatic conveyors carrying combustible material.
2.5.2.3.2 Protect pneumatic conveyors carrying noncombustible material with two 3-hour fire-rated dampers located in the fire wall. (Provide at least one in each wall in the case of a double wall.) Arrange the dampers for automatic closure by activation of detectors rated at 135°F or 165°F, or 50°F above ambient temperature (57°C or 74°C, or 28°C above ambient temperature) located on each side of the wall (Fig. 73).
