If im correct i think grain dust can be explosive or highly flamable when exposed to certain things ?

Both are correct, if the dust oxygen mix is correct then it will be eplosive, if it's slightly off then it just burns very very quickly. Hence why strictly no smoking in and around grain bins. Unless you're stupid like some of the guys I used to work with who did.

Hi guys, - would the same danger there be the same thing as it was portrayed in Ladder 49 the movie ?? - I know it was a movie, but, wasn't it also a grain silo that went up with all sorts of explosions?

Why is grain so volitile?

[chemistry lesson]

Wheat and other grains contains matter that can burn (carbon based stuff like in wood). In the wheat form there's not enough exposed surface area for it to burn quickly. Grind it up and turn it into flour or a dust-like form the surface area increases which means more can burn, more rapidly. This makes it appear to explode - which really means it is burning super fast. It's like petrol - the vapour explodes (more exposed surface area) while the liquid (less surface area) doesn't.

erk! Just looked up and saw the smoke!

South of Mt Helena but I can't tell how far away... Sawyers Valley or further south than that?

Yeah, noticed the smoke a little bit ago also.. Haven't heard anything on the fire channel though. I heard the police mention a few mins ago theres a fire over around Armadale, but nothing else regarding fires.

I guess it is permit burning season now in Mundaring shire - could be one of the brigades having a big burn. We have one scheduled in a couple of weekends time...

Dunno where it is, but this morning there was talk of something going down at Gidge, possibly even DEC.

I think from memory there was a DEC burn planned south of Sawyers Valley.
