Chris and Belinda from the CFS have put together some helpful hints for students making a 2021 poster entry about bushfire safety.
You and your family's safety and survival during a bushfire can depend on how prepared you are, and the decisions you make. You can find out a lot of information on how you can reduce the impact of bushfires and increase your safety at https://cfs.sa.gov.au/home
There are several actions you can take to ensure you can be as safe as possible before, during and after a bushfire or emergency.
Bushfire Planning and knowing bushfire behaviour
Every year there are 756 bushfires on average throughout South Australia. About 67% are in the most densely populated areas like the Mount Lofty Ranges.
One of the most important things to do before summer starts is to plan what you will do as a family and at your home. This includes preparation before, during and after a bushfire. There is a lot of science involved in bushfires. This includes knowing key influences for bushfire such as fuel loads and ambient temperatures, and activities which can start fires. By considering these aspects when planning and working out how to reduce your bushfire risk, you are helping to keep yourself and your family a lot safer.
Emergency Warnings and Messages
One of the most important parts of any disaster is getting the right information out to people quickly to help them make decisions about their own safety. Because fires can be fast moving and dangerous it is important that warnings are very clear and written in such a way that people can understand them so that they take the right action. A scientific approach and understanding of Psychology has been used to research how people read and understand warning messages in dangerous situations and this informs how the messages are structured.
Bushfire Safer Places
The CFS designates areas called Bushfire Safer Places which are areas that have been deemed to provide some level of protection from the heat and flames of a bushfire. These are the safest places to be during a bushfire. The way these areas are determined is by measuring how much vegetation is in an area and doing a calculation of how hot a fire would be if that vegetation burned. Using physics and an understanding of heat transfer, heat radiation, and energy we can work out how far away you would need to be from the vegetation to not burn from the heat radiation.
Hopefully these three examples point out some links that you may not have thought of and help you see other ways in which science helps us make decisions in the real world and keep people safer!
We are proud to have The SA Country Fire Service and Australian Institute for Disaster Resilience as our Poster Category sponsor this year!
