CFD can be used both in the design phase and in the performance assessment phase for the evaluation of the performance of safety and fire protection systems in the presence of fires of different intensity, duration and location. In the paper, a detailed analysis has been carried out using a general purpose CFD code (FLUENT v. 6.3.26), with the objective to demonstrate the capability of this widely used code in assessing, in addition to the thermal-fluid dynamic field of the smoke, useful parameters concerning tenability criteria and visibility. The limitations that must always be considered in evaluating the results obtained by using these numerical tools have been evidenced. The analysis was conducted inside a typical store in a commercial building in order to obtain a preliminary assessment of the effectiveness of the extinguishing systems (i.e. the sprinkler system) in limiting the temperature and the concentrations of toxic gases and assuring acceptable visibility into the environment, to guarantee a safe evacuation of workers and public from the burned store.
