The fire protection measures considered in the fire risk analysis steps for their benefits in reducing the effects of fire events upon the overall performance of a "building-occupant" system.

Fire Protection Engineers (FPEs) need to evaluate how these fire protection measures are integrated in the system, so because of the challenges related to the maintenance and the possible changes of the building use once the design phase and the construction phase are done. This 5th important step of the new PBFPD process is performed in order minimize the incompatibility of the fire protection measures with the components used in an everyday basis. In other terms, this step assesses the fire protection measures, which are the most efficient according to the fire risk analysis, are not counter-productive and therefore ignored or worse rejected by the system, ultimately rendering them inoperative during an actual fire event. This step goes beyond the documentation on how the fire protection measures are designed, installed and maintained in the current PBFPD processes.

Tools such as the ones elaborated for system dynamics could be valuable to perform this new PBFPD process.

Databases are required to gather elements of the system functionality including contingency plans established to deal with emergency situations.

'Test bed" environments are built so to consider the specificities of "building-occupant" systems and their related fire event issues.
