BAL Rating Perth

BAL Rating

BAL Ratings measure the potential bushfire risks on your property. Lowering your BAL rating will reduce the risks and effects of a bushfire, and help you protect your community. Entire Fire Management are Perth Bushfire Consultants with over 50 years of experience. We know firsthand the devastating effects of bushfires in Western Australia, and want to keep you and your family safe.

 

What is a BAL? A Bushfire Attack Level measures the potential intensity of a bushfire, and the impacts it could have on your home.

How does a BAL Rating apply to you?

  • The lower your BAL rating, the less vulnerable your home is in a bushfire.
  • By taking measures to reduce your property’s BAL rating, you’re lowering the impact of a bushfire on you and your community if one occurs.
  • BAL Assessments and BAL ratings are used in planning and building sectors to ensure all future developments in bushfire prone areas are built with the safety and protection of the community in mind.
  • If you’re building or planning a new development in a bushfire prone area in Perth, BAL Assessments are essential for proposals that comply with the State Planning Policy 3.7 and the Australian Standard 3959 Construction of Buildings in Bushfire-Prone Areas (AS 3959).

What are the Bushfire Attack Levels, and what do they mean?

BAL-LOW – Very low risk/optimum level:

  • There is a very low risk of a bushfire directly impacting your house and therefore, no specific construction requirements required.

BAL-12.5 – Low risk:

  • You’re reasonably safe. Embers may reach your house where the building is less than 100m from the source of the bushfire attack, but if the house is built correctly, they will not penetrate the building. Primarily concerned with protection from ember attack and radiant heat greater than 12.5 kW/m² up to and including 19 kW/m².
  • Firefighters are able to access you, and actively defend your property.

 

BAL-19 – Moderate risk:

  • You’re reasonably safe. Embers may reach your house where the building is less than 100m from the source of the bushfire attack, but if the house is built correctly they will not penetrate the building. Primarily concerned with protection from ember attack and radiant heat greater than 12.5 kW/m² up to and including 19 kW/m².
  • Firefighters are able to access you, and actively defend your property.
  • A BAL-19 rating is often the optimum balance between adhering to building requirements and having an adequate APZ safety zone (so firefighters can actively defend your home), without compromising the environment.
  • When developing a Bushfire Management Plan and Bushfire Management Statement, we strive to mitigate the risks to achieve a BAL-19 or below, so your property is the safest it can be.

 

BAL-29 – High risk:

  • High risk of flame contact with building. Primarily concerned with protection from ember attack and radiant heat greater than 19 kW/m² up to and including 29 kW/m².
  • Although deemed acceptable under State Planning Policy 3.7, when safety is concerned, it’s not ideal.
  • There’s an inadequate safety zone making it very difficult for firefighters to defend your home.
  • When developing a Bushfire Management Plan and Bushfire Management Statement, we strive to mitigate the risks to achieve a lower rating than a BAL-29, so your property is the safest it can be.

 

BAL-40 – Very high risk:

  • Very high risk of impact from a bushfire. Primarily concerned with protection from ember attack, increased likelihood of flame contact and radiant heat greater than 29 kW/m² and up to and including 40 kW/m².
  • No safe zone for firefighters to actively defend your home.
  • Construction of a building with a BAL-40 rating would be unsafe for its occupants.
  • Your planning application is likely to be referred to other relevant departments for review and comment. If it’s not possible to reduce your BAL rating through bushfire mitigation, allow extra time for this process.
  • When developing a Bushfire Management Plan and Bushfire Management Statement, we strive to mitigate the risks associated with this rating, so your property is the safest it can be.

 

BAL-FZ – Extreme risk:

  • Extreme risk of flame impact from a bushfire. Primarily concerned with protection from flame contact, together with ember attack and radiant heat of more than 40 kW/m².
  • No safe zone for firefighters to actively defend your home.
  • Construction of a building with a BAL-FZ rating would be extremely unsafe for its occupants.
  • When developing a Bushfire Management Plan and Bushfire Management Statement, we strive to mitigate the risks to achieve a lower rating than BAL-FZ, so your property is the safest it can be.
  • Construction within BAL-FZ may require reliance on measures other than construction. Building authorities within each state regulate the requirements for construction of a building in the Flame Zone.

 

It’s inevitable there will be a shortage of fire services in the event of a bushfire–this is the harsh reality. What can you do?

 

The best way to reduce the threat of a bushfire is to mitigate the risks around your home, and create a safety zone for firefighters to access you. Building your home so it has a BAL rating of BAL-29 and below will mean you’re protecting it from embers and flames, giving it the best chance to survive.

 

Although the acceptable BAL rating in the Western Australian planning system is below a BAL-29, at Entire Fire Management we aim to achieve BAL ratings below BAL-19 through appropriate mitigation strategies, so we can ensure you’re as safe as you can be.
