This graphic designer phoned it in for this one. I guess he didn't want to pay for the cloudy graphic he'd need to make it actually look like a fire extinguisher. "I'll just throw fire in there. That looks like a fire extinguisher." No, bro. It looks like a flame thrower. That's totally bad ass, but maybe it's not exactly what someone needs when they want to extinguish fires.
That would be awesome if every building had a little glass case with a flamethrower in it the way they do with fire extinguishers. I'm not saying it's the most useful item, but how many times a year does a fire extinguisher get used? I bet you've never even used your fire extinguisher. In fact, no one wants to use a fire extinguisher. That means there's a fire. Fires suck!
