A simple spill of a little gasoline on the floor is unlikely to burn a building down, as there is not enough of it to go the distance. Now, the fire triangle may have changed since way back when, but I haven't heard of any changes to it. Please correct me if I am mistaken.
You are mistaken. Local concentration of vapor can occur any time any place for reasons which are entirely overlooked until something exciting occurs. The more you tempt fate the more likely something will occur.
It's a good thing not many will ever wax a chain as the handling of solvents described here is fully insane. Oh, you've been doing this for years and you have been lucky so far? Does not reduce the hazard.
I will tell this story again. Once on a group ride one of the guys came over to my house afterwards for some mechanical assistance. We go down to basement and first thing he sees is a vented double wall fusible link fire safe flammables storage cabinet. Which I owned then because I was handling a lot of solvents. My friend, not a close friend at all, was a Chicago firefighter. He saw that fire safe and took a cab home. Just gave me his bike. His number one bike. Because someone took fire safety seriously.
