Do you know the mixture rates for this? I have heard that Sodium Silicate is good way.
I may be a bit paranoid about this but I used to be in the stove/fireplace business and have seen a lot of things you would not think would happen. We recently had a restaurant burn due to spontaneous combustion of animal fats. We see a lot of wood mills go down in flames for things you wouldn't think would happen. Since my shop is adjacent to a retail establishment I am pretty cautious.

The superscientific dilution ratio- mix it into water until it floats an egg. If you get too saturated of a solution you loose some penetration value, and only have a surface coating.
My preference is to continue spraying the wood until the solution no longer penetrates into the wood. It works best by starting at a point on the wall, and working your way around the room. If a coat is allowed to fully dry, you are sort of screwed getting the next coat to hang.
Wood & strange things, well, there is the cumulative effect of constant exposure to temperature lower than the kindling point, such as tossing a crumpled electric blanket on the footboard of a bed. Seen that cook a house pretty well.
Spontaneous combustion of animal fat, I'd like to hear how the person who made that call justified the conclusion. Seems like there is too much water in animal fat for the reaction to occurr. Now, if the fat was in contact with pool chlorine, it could get interesting fairly quick.
Wood mills, are often a lot like grain storage. Fine dust explosions require very little to ignite them, and the combustion ratio of dust is very easy to acheive. Then there are those friendly folks who just toss a cigarette **** because they were born stupid and stayed that way.
