I keep all my gear away from fire. What doesn't melt burns or explodes. :P

And I've given some thought to this. If it flares somehow, half the matches are upside down, so it won't be as large an explosion if any. The seal is water proof, and as close to gas tight as I can make it, so any oxygen will get used up fast. And there is padding at either end, there is always long-axis give but very little short-axis, so they are extremely unlikely to go up from a sharp shock. I'm moderately confident that body of the match safe will contain any explosion that MIGHT, SOMEHOW occur, and if it doesn't, it has 8" of gear to go through to get to me, and possibly a pack frame.

And I'll just tell people it is a match safe. The lighter backs that up. If it was something unsocial, it would just be match heads, rather than wasting space like this. This is more a pipe bomb than metal can full of ammunition is. If you are worried about how some self righteous, pompous twit might think of your gear, then let's face it, most of us here could be charged with possession of bugler's tools, or carrying a deadly weapon. (Sorry to our UK members, who already have this issue with EDC.) I'm not going to compromise my gear for what some pencil pushing, drippy nosed bureaucrat thinks. I don't carry this down town, it's in my camping gear.

Which also has liquid and solid fuels, knives, flares, some pretty large quantities of OTC meds that have been repacked, and often ammunition. If someone wants to gig me, I'm SOL, and I know it. But then again, if this is on black top, things would have to be pretty bad. *shrugs*
