Leo - Have you seen the two big doors .
If weve had a fire in there the doors will be left open and clear untill it is safe enough to enter. We had to make ventilation holes in the roof so that it doesnt heat up too much, or get too full of smoke - but some form of induction for them is also something to look into in the near future.
But first - we want to make sure the rest of it works well enough!
