The essence of fire safety is to ensure that the fire systems in place and available at a facility are suitable to meet the risks presented by the potential fire scenarios at the facility.  This is achieved by modelling the likely impacts of a fire (e.g. tank fire, bund fire, pool fire, jet fire etc.) and then determining the fire protection resources needed to protect against those events. This ensures that the fire system is suitable to properly manage the fire risk and not just meet minimum requirements, as set out in codes and standards.  The requirements of a fire protection system can first be established via consequence modelling of the fire events and then the performance of the fire protection system can be determined via hydraulic modelling of the fire protection systems (e.g. fire pumps, hydrant ring main, sprinkler / deluge systems etc.)
