General Hazard 
The following statistics indicating type and severity of domestic fires was obtained from Dowling and 
Ramsay (1997), Australian Bureau of Statistics: Home Fire Safety (2000), Fire Statistics UK (2002): 
• 
70% of fires are caused by the misuse of equipment including cooking appliances, candles, heaters, 
electrical appliances 
• 
20% of fires are due to arson 
• 
10% of fires are due to electrical faults 
• 
3% of fires start outside 
• 
2.2% of fires, which start inside, spread beyond the building of origin 
• 
76% of reported fires do not spread beyond the room of origin whether by good fortune or by 
occupant intervention 
• 
80% of fires are not reported to the fire brigade. They are extinguished by occupants while the fires 
are small 
• 
30% of fires start in kitchens, 10% in bedrooms i.e. approximately 3% per bedroom. 
From the above statistics it is evident that only a small fraction of reported residential home fires start 
outside the building and an even smaller fraction of fires that start inside the building, spread beyond the 
building of fire origin. Unreported fires (which make up approximately 80% of all fires) are typically those 
that are extinguished, further reducing the number of fires that spread beyond the building of fire origin. 
Based on the statistics, as the building contains fire load of a relatively small scale, it is unlikely that a fire 
within the building will spread to the neighbouring building and as a result, the hazard of occupants being 
exposed to heat and/or smoke is low.

Performance to be Assessed 
The performance solution must be assessed for whether it mitigates the identified hazards to performance 
requirement: 
H3P1 – Spread of Fire: 
(1)  A Class 1 building must be protected from the spread of fire such that the probability of a 
building not being able to withstand the design heat flux of 92.6 kW/m2 for a period of 60 
minutes shall not exceed 0.01, when located within 900 mm from the allotment boundary or 
within 1.8 m from another building on the same allotment from – 
(i) 
Another building other than an associated Class 10 building; and 
(ii) 
The allotment boundary, other than a boundary adjoining a road or public space. 
4.4 
Systems 
The systems proposed are: 
(h) This performance solution is solely applicable to a roofing system incorporating Panel Type I and 
Panel Type II in the orientation (and observing the dimensional constraint) indicated in Figure 3-4. 
The roofing system may be supported by a non-combustible supporting structure and have non-
combustible plumbing fixtures (gutters and downpipes). Panel Type I and Panel Type II may 
comprise of either the DeltaTrim™ system profile or DeltaOrb™ system profile and shall adhere 
fully to the overall system requirements outlined within Section 3.  
(i) 
All components used in the awning construction shall be compliant with Section 3. The 
components shall not be modified except with the written authorisation of the manufacturer and 
SOTERA.  
(j) 
The following restrictions apply for the Class 10a awning or patio roof installation:
