Dealing with fire damage
Much smoke and soot damage is treatable.
Remember that as water is the main method used to fight fire, much of the advice relating to flood damage will apply with fire damaged items.
Fire leaves most metal things rusty and dirty. Tetanus is a significant risk, especially when cleaning through the remains of sheds.
If you plan on entering a fire damaged site, the FIRST thing you should do is to see your GP and get a tetanus shot.
Fires produce highly toxic smoke and soot and structurally damage buildings. You will not be able to re-enter your premises until it has been assessed by authorities as safe to do so.
