Hazards 
4.2.1 
Specific Hazard 
The NCC Schedule 1 defines fire hazard as the danger in terms of potential harm and degree of exposure 
arising from the start and spread of fire and the smoke and gases that are thereby generated. As such, the 
BCA definition of a hazard relates to the potential for occupants to be exposed to heat and/or smoke. 
The intent of NCC 9.2.4 & 9.2.9 is to reduce the risk of fire spread between Class 1 buildings on 
neighbouring allotments as per performance requirement H3P1(1). The hazard associated with the 
variations to NCC 9.2.4 & 9.2.9 is the potential for fire spread between buildings to expose occupants to 
heat and/or smoke. 
Whether the DeltaDualCore™ system when used within 900 mm of a site boundary presents an 
unacceptable risk of fire spread between buildings (which could significantly increase the hazard of 
building occupants becoming exposed to heat and/or smoke) must be assessed.  
The identified hazard shall be considered in three fire scenarios (see Figure 4-2): 
i) 
Fire starting in the Class 1 building. 
ii) 
Fire starting below/in the Class 10a structure. 
iii) 
Fire starting on the neighbouring site.
