- Beams that are less than 0.3 m below the slab need not be considered. Obstructions greater than 300 mm (12”) can affect the distribution of agent and may require additional nozzles. - The max. elevation difference between the container outlet and the furthest horizontal pipe run or discharge nozzle (whichever is furthest) shall not exceed 9.1 m.

- The max. elevation difference between the furthest horizontal pipe runs or discharge nozzles (whicheve is furthest) shall not exceed 9.1 m. - The agent design concentration shall be checked to insure that it is under NOAEL at maximum anticipated temperature in the hazard space. - Sizing is based on NFPA-2001
