They are:(a)BAL-LOWThere is insufficient risk to warrant any specific construction requirements but there is still some risk(b)BAL-12.5There is a risk of ember attackThe construction elements are expected to be exposed to a heat flux not greater than 12.5 kW/m 2(c)BAL-19There is a risk of ember attack and burning debris ignited by wind borne embers and a likelihood of exposure to radiant heatThe construction elements are expected to be exposed to a heat flux not greater than 19 kW/m 2(d)BAL-29There is an increased level of ember attack and burning debris ignited by wind borne embers and a likelihood of exposure to an increased level of radiant heatThe construction elements are expected to be exposed to a heat flux not greater than 29 kW/m 2(e)BAL-40There is a much increased risk of ember attack and burning debris ignited by wind borne embers, a likelihood of exposure to a high level of radiant heat and some like likelihood of direct exposure to flames from the fire front.The construction elements are expected to be exposed to a heat flux not greater than 40 kW/m 2(f) BAL-FZThere is an extremely high risk of ember attack and burning debris ignited by wind borne embers, a likelihood of exposure to a high level of radiant heat and some like likelihood of direct exposure to flames from the fire front. The construction elements are expected to be exposed to a heat flux not greater than 40 kW/m 2Delta Panels Pty Ltd - ABN: 11 147 861 292E: info@deltapanels.comHead Office: 731 Boundary Road, Richlands, Qld 4077P: +61 7 3271 2170 Version Date: 2024-04-30W: www.deltapanels.com Sydney Depot: 11 The Old Northern Road, Narellan, NSW 2567 P: +61 2 4611 7712'
