Bushfires-How Do They Affect A Home?
Bushfires affects a home in several ways
usually occurs up to 30 minutes prior to the arrival of fire front and for several hours afterwards.
Burning debris such as sparks and embers are carried by strong winds ahead of the fire front. They can fall on or around the home, igniting small spot fires where they land. If not extinguished quickly, they can grow into a major fire that will eventually destroy the house. 'Fine fuels' such as dry grass and pine needles are most likely to feed such spot fires.
Ember danger spots include: roof cavities, complex roof lines, roof gutters, underfloor spaces, wooden decking and steps, windows and door frames, broken windows, door mats, dried out lawns, vegetation and mulch.
To guard against ember attack:
- regularly reduce the amount of fine fuel around your property well before and during the bushfire danger period.
- incorporate design and construction features to exclude the entry of embers into eaves and wall/floor vents
- patrol the house to check on vulnerable spots and douse spot fires (if able bodied people available)
Direct Flame Contact and Radiant Heat
arrives with the fire front and lasts from 10 – 15 minutes.
Radiant heat causes objects on and around your property to rapidly reach the point at which they will ignite. Minimise combustible materials in and around your home, including choice of materials for fences, decks, and roof; choice of vegetation species and mulches; and storage of chemicals, wood and compost piles.
Exposure to radiant heat can cause heat exhaustion and may be fatal to humans.
