Step 1 Identify the hazard to protect and note the applicable design concentration number. Example: Hazard is Class C (Energized) 4.5% 4.7% required Round up design concentration to 5% (next whole number) L = 2 ft. W = 5 ft. H = 8 ft. Electrical Control Cabinet Step 2 To identify the flooding factors number determine the enclosure’s minimum temperature and align this with the rounded up design concentration number in Table 2 left. Example: Minimum temperature is 70°F, rounding up number is 5; therefore flooding factor number is 0.0455. Step 3 Calculate cubic feet of enclosure by multiplying the width x length x height. To identify required system size multiply cubic feet of enclosure by the flooding factors number. Example: Enclosure is 5 ft. W x 2 ft. L x 8 ft. H = 80 cubic feet. 80 x 0.0455 = 3.64. This would round up to the 7 lb. system. Step 4 Use Table 3 to double check that the enclosure to be protected does not exceed the maximum area coverage of the tested nozzles and the volume coverage does not exceed the maximum hazard volume of enclosure in Table 4. Example: The enclosure is 10 ft2 and the max coverage of 7 lb nozzle is 108.10 ft2. The 7 lb system can protect up to 153.8 ft3 at 70°F with a design concentration of 5%.
