I see now. The other two were obvious, but roof work seemed counter-intuitive. But if epoxy is used in the process, then yeah, I totally see that. I ended up with a garage full of smoke a couple times from working with more resin than I really needed for my projects.
- m4rtink 6y agoRoof work sometimes involves applying tarpaper with a.small flame thrower. That genereates quite a few fires.if you are not careful.
- oliveshell 6y agoYup. My uncle's house burned down, years ago, due to careless use of a torch to apply tar roofing.
- myself248 6y agoIt blows my mind that the torch isn't fed with two hoses: One of propane-or-whatever, and one of CO2. If something goes badly, you literally move one finger and start extinguishing the fire. Why on earth would you want the problem closer at-hand than the solution?
- m4rtink 6y agoThat's simple - cost and convenience. You would have to buy, maintain and lug to the roof yet another heavy preassure vessel. Also twice the hoses & more likely the two will get entangled. Having a fire extinguisher at hand seems like a better option.
- janekm 6y agoBut presumably also the common use of big torches for materials like torch-on-felt?
- jacquesm 6y agoRetrospectively we came to the conclusion that he had mixed in too much hardener. Incredible how fast that went. From 'hot to the touch' to 'poof'. Nearly colorless flame too, super dangerous. Fortunately I got it covered before it got worse. That wasn't heroic either, I had to get past the bloody vat to get to safety so I figured I'd better stop it burning first.
