factors, each operating across different spatial scales. Nevertheless, strategies
aimed at mitigating the impacts of direct flame contact, radiant heat exposure, and
ember attack can be effectively addressed within the framework of land use planning
and development assessments, conducted at manageable scales.

The main sources of direct bushfire attack that give rise to loss of life, and damage to
property and infrastructure are as follows:

   5.2.1 Direct Flame Contact

Direct flame contact occurs when flames from a bushfire come into direct contact
with a building, structure, or individuals. When this happens, the flames can ignite
any flammable material present and cause fires to spread rapidly. Direct flame
contact can also cause burns and other heat-related injuries to people who are in the
path of the flames.

Direct flame contact is a significant concern during a bushfire, especially for buildings
and structures that are located in close proximity to the fire. The intensity of the
flames and the duration of the exposure can have a significant impact on the severity
of the damage.

To reduce the risk of direct flame contact during a bushfire, it's essential to create a
defensible space around buildings and structures, clear flammable materials from
the area, and use fire-resistant building materials when constructing or renovating
buildings. Additionally, it's crucial to follow evacuation orders and stay informed
about the fire's behaviour and movement to ensure personal safety.

   5.2.2 Radiant Heat Exposure

Radiant heat exposure is a significant danger during a bushfire. When a bushfire
occurs, the heat generated by the flames causes the air surrounding the fire to heat
up, and this heat energy is then radiated out in the form of electromagnetic waves.
These waves can travel a considerable distance from the fire and can cause
surfaces that are not in direct contact with the flames to heat up.

During a bushfire, radiant heat exposure can be intense, and the effects can be
severe. Radiant heat can ignite flammable materials, such as dry vegetation or
wooden structures, and cause them to catch fire. It can also cause buildings and
structures to overheat, leading to structural damage or collapse. Additionally, people
who are too close to the flames can suffer from heat stress, dehydration, and serious
burns.

The risk of radiant heat exposure during a bushfire can be mitigated by creating a
defensible space around buildings and structures, clearing flammable materials from
the area, and using fire-resistant building materials when constructing or renovating
buildings. It's also important to follow evacuation orders and stay informed about the
fire's behaviour and movement to ensure personal safety.
