With Andrew and Drew (Carleton) going back and forth here, I'd like to interject.
Andrew, what I think Drew is getting at (and has since replied with since I wrote this, but going to leave this anyway) is that it seems you are saying FMB could basically say ANYTHING is a fire safety violation (even if there are no flammable liquids involved, not comparing this to the propane tank), and suddenly that team is in trouble. I know (and agree) that teams should just be asking first, but it leaves a HUGE door open for FMB to basically call anything a fire hazard and the head judge then is required to DQ.
Another point I wanted to add myself is with regards to smoking. I used to do it myself very "near" trucks because it was never seen as a problem, but looking back I don't see how that's the case. With the smells that come from various orgs prep areas, there are some serious fumes floating around, and you often have lots of cigarettes lit up (SigNu comes to mind here. Not saying you guys are unsafe, just remember you as a lot of smokers). To me, people using lighters and having sticks of flaming ash in their mouth about 5 feet from their trucks/tents seems much more dangerous than any propane tank (especially one that was turned off, and yes I understand it could leak). I don't know the physics of propane, or much about fire safety, so tell me if I'm out of line here, but just something that particularly struck me on Saturday when this was all crashing down on SDC.
