b'Delta MW and EPS-FR Panel Awning and Patio Roof System 4.2Hazards 4.2.1Specific Hazard The NCC Schedule 3 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 Delta MW and EPS-FR roof 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.Boundary CLASS 1 CLASS 10a i) FIRE STARTING IN THE CLASS 1 BUILDING Boundary CLASS 1 CLASS 10a ii) FIRE STARTING IN THE CLASS 10a STRUCTURE Boundary CLASS 1 CLASS 10a iii) FIRE STARTING ON THE NEIGHBOURING SITEFigure 4-2.
