Bush fire blanket project
Posted on January 29th, 2020
- Effective strong fire fighting capability without the use of water or consumable suppression liquids or materials.
- Must be re-useable
- Must deploy in less than 15 minutes for a residential or rural single story dwelling.
- Must be deployable by 2-3 semi experienced fire fighters.
- Must cost less than $5,000AUD per blanket.
- The steel mesh approach for covering houses and grass fire smothering was dismissed as even the smallest embers can stil ignite fires if they can pass through the mesh.
- A full no mesh blanket approach that utilised 100 square metre blankets being dragged or positioned by a mobile crane was discarded due to its dependence on availability of mobile cranes. There is just not enough of them. And the ability to manually drag the blankets across ground using fire resistant chains and winches either manually or on vehicles negated the need for the specialised mobile cranes. Fire blanket crane deployment above. Crane is way too big for the weight (approx. 200kg) but was used for illustrative purposes.
- Another research area has been frustrated covering a method for quickly deploying a blanket over a residents house with an approaching fire. The technique considered involved catapulting the blanket from one side of the house to the other to allow quick 2-3 man operation and a 15 minute deployment time frame.
