AS3959
AS3959 is an Australian standard for construction of buildings in bushfire-prone zones. The standard was first proclaimed in 1999. The 2009 release of AS3959 (AS3959:2009), which took into account findings of the Black Saturday bushfires, had significant changes from earlier versions, bringing major changes to construction of homes to be built in the future. Under this standard all proposed building requires the builder or landowner to undertake a BAL (Bushfire Attack Level) Assessment. This requires a report tabled to establish the threat of bushfire on this future proposed dwelling. The report takes in matters such as the area FDI (Fire Danger Index), the block's ground slope, vegetation type and density to determine the intensity of fire attack, split into 6 levels. The six levels relate to the intensity of radiant heat exposure, with the levels being BAL-LOW (no threat or construction changes needed), BAL-12.5 (Radiant Heat levels would calculate 12.5 kW/m2), BAL-19 ( ...

Bushfires In Australia
Bushfires in Australia are a widespread and regular occurrence that have contributed significantly to shaping the nature of the continent over millions of years. Eastern Australia is one of the most fire-prone regions of the world, and its predominant eucalyptus forests have evolved to thrive on the phenomenon of bushfire. However, the fires can cause significant property damage and loss of both human and animal life. Bushfires have killed approximately 800 people in Australia since 1851, and billions of animals. The most destructive fires are usually preceded by extreme high temperatures, low relative humidity and strong winds, which combine to create ideal conditions for the rapid spread of fire. Severe fire storms are often named according to the day on which they peaked, including the five most deadly blazes: Black Saturday 2009 in Victoria (173 people killed, 2,000 homes lost); Ash Wednesday 1983 in Victoria and South Australia (75 dead, nearly 1,900 homes); Black Frida ...

Standards Australia
Standards Australia is a standards organisation established in 1922 and is recognised through a Memorandum of Understanding (MoU) with the Australian government as the primary non-government standards development body in Australia. It is a company limited by guarantee. As of 1998, it had 73 members representing groups interested in the development and application of technical standards and related products and services. The MoU recognises Standards Australia as Australia's representative on the International Organization for Standardization (ISO), the International Electrotechnical Commission (IEC) and the Pacific Area Standards Congress (PASC). Standards Australia develops internationally aligned Australian standards (AS) and participates in standards-related activities. Standards Australia and Standards New Zealand work together to develop joint standards (AS/NZS). Licensing of the sale of standards In 2003, Standards Australia sold its standards publication business and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Saturday Bushfires
The Black Saturday bushfires were a series of bushfires that either ignited or were already burning across the Australian state of Victoria on and around Saturday, 7 February 2009, and were among Australia's all-time worst bushfire disasters. The fires occurred during extreme bushfire weather conditions and resulted in Australia's highest-ever loss of human life from a bushfire, with 173 fatalities. Many people were left homeless as a result. As many as 400 individual fires were recorded on Saturday 7 February; the day has become widely referred to in Australia as Black Saturday. The 2009 Victorian Bushfires Royal Commission, headed by Justice Bernard Teague, was held in response to the bushfires. Background A week before the fires, a significant heatwave affected southeastern Australia. From 28–30 January, Melbourne broke temperature records by experiencing three consecutive days above , with the temperature peaking at on 30 January, the third hottest day in the city' ...

List Of Major Vegetation Groups In Australia
This is a list of Major Vegetations Groups and Subgroups in Australia. Major Vegetation Groups and Major Vegetation Subgroups are categories used by the Department of the Environment and Energy as part of its National Vegetation Information System. The Major Vegetation Groups are broadly defined as representative of distinct vegetative environments; they may extend over large areas and often contain more than one vegetation association or community. They were originally defined as part of the National Vegetation Information System framework for the Australian Native Vegetation Assessment 2001. As of 2022, the most recent update was version 6.0, in 2020.

Thermal Radiation
Thermal radiation is electromagnetic radiation generated by the thermal motion of particles in matter. Thermal radiation is generated when heat from the movement of charges in the material (electrons and protons in common forms of matter) is converted to electromagnetic radiation. All matter with a temperature greater than absolute zero emits thermal radiation. At room temperature, most of the emission is in the infrared (IR) spectrum. Particle motion results in charge-acceleration or dipole oscillation which produces electromagnetic radiation. Infrared radiation emitted by animals (detectable with an infrared camera) and cosmic microwave background radiation are examples of thermal radiation. If a radiation object meets the physical characteristics of a black body in thermodynamic equilibrium, the radiation is called blackbody radiation. Planck's law describes the spectrum of blackbody radiation, which depends solely on the object's temperature. Wien's displacement law de ...

Fire Protection
Fire protection is the study and practice of mitigating the unwanted effects of potentially destructive fires. It involves the study of the behaviour, compartmentalisation, suppression and investigation of fire and its related emergencies, as well as the research and development, production, testing and application of mitigating systems. In structures, be they land-based, offshore or even ships, the owners and operators are responsible to maintain their facilities in accordance with a design-basis that is rooted in laws, including the local building code and fire code, which are enforced by the authority having jurisdiction. Buildings must be constructed in accordance with the version of the building code that is in effect when an application for a building permit is made. Building inspectors check on compliance of a building under construction with the building code. Once construction is complete, a building must be maintained in accordance with the current fire code, which is e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
