You need an agent, ingnition source, and oxygen. There is a low and high level of ignition and also the enviroment condition comes into play.
Pop just didn't have the right condition. Didn't mom ever tell you that if you play with matches you'll get burnt!

DiD you happen to notice that vapor SMOKE coming OFF the cut?? Want to bet that it is VERY close to the ignition point?

if it is vapourising and making "smoke" then it will be at or above its flashpoint. If any portion of the work sparks or becomes incandescent there is a high risk of a flashover.

You can get vegetable based water soluble coolant - Ometa make it in various flavours.

As an aside, i used to run my old diesel Escort on waste vegetable oil, it smelled of kebabs and nasty meats but it worked surprisingly well. the cost of fresh veg oil and indeed used veg oil in the UK has murdered any chance of saving money by making biodiesel but WVO can still be had for running as a straight fuel.
