Sprinklered Computer Model of Stage Area with Fire Dynamics Simulator (FDS) and Smokeview

Video of Report of the Technical Investigation of The Station Nightclub Fire

Another simulation of the full nightclub was completed in order to examine the effects that sprinklers may have had on the fire and the environment. The input from the FDS incident simulation was combined with the input from the FDS sprinklered full-scale mock-up simulation. Five sprinklers were placed in the simulation. One was located in the center of the alcove and the other four were placed using 3.6 m (12 ft) spacing. The west sprinklers were 1.8 m (6 ft) north and 1.8 m (6 ft) south of the alcove sprinkler and 1.8 m (6 ft) east of the platform wall. The east sprinklers were also 1.8 m (6 ft) north and 1.8 m (6 ft) south of the alcove sprinkler and 12 ft east of the west sprinklers. While the maximum allowable sprinkler spacing would have been 4.6 m (15 ft) throughout the main portion of the nightclub, the alcove would have required an individual sprinkler regardless of the sprinkler spacing used elsewhere in the nightclub. In the un-sprinklered cases, flashover of the alcove increased the rate of hazard development significantly. The single sprinkler in the alcove (which was full-scale) was shown to prevent flashover in both the sprinklered experiments and the simulations, significantly mitigating the hazard.
