Well - this is vitally important if you ever are affected by fire.(Which I hope not)
From the "The Australian Institute for the conservation of Cultural Material" they have put together some information that may help ease the heart-break and allow items to be salvaged.
Since the Black Saturday fires, we all recognise that fires of a catastrophic degree can cause extreme damage on a scale previously unimagined. However, stories that have emerged from the experience tell us also that some treasures did survive. Even some paper-based items miraculously endured intense heat, soot and fire. With careful storage and by using heat-resistant materials, certain risks can be reduced. While not a guarantee that items will not suffer damage, minimising risk through the storage methods recommended may offer some hope for items that have to be left behind on evacuation.
If you are affected by fires, the AICCM encourages you to retain any damaged keepsakes and memorabilia that are still recognisable, even if damaged and dirty. Consult a conservator before you throw them away. It is possible that they may be salvageable.Please refer to this link for full details and downloadable information that can be of assistance, both, before and after. http://www.aiccm.org.au/index.php?option=com_content&view=article&id=1117:protecting-your-possessions-against-bushfire&catid=11:media-releases&Itemid=52
Take care out there and remember a scanned photo, may not replace the original BUT, it preserves the image.
Refer my post about data storage and remember you can't always remember everything, especially when under pressure and worry - http://itaintalwaysso.blogspot.com/2009/10/how-safe-is-data-in-your-safe.html
