I just have a fear I might mess up somehow and start a fire or something
It takes some effort to start a fire. Most oils flash points are >600 F, which you might get a pan to to sear a steak, but to heat a pan of oil for deepfrying or something to >600 F, which would be a dangerous situation, requires you to continue heating it after it started billowing smoke between ~350F and ~525.
In any case, if you manage to have an oil fire, say by spilling some on the burner, just let it burn out if it’s a small amount or turn off the heat and throw a towel over it if it’s like a cup’s worth.
Minor burns aren’t uncommon when you’re learning, but that’s just a very quick way to learn “wrap the handle of the cast iron you just took out of the oven with a towel so you don’t grab it like a moron” or “use tongs to place things on hot oil so it doesn’t splatter on your hand”
I wonder if the guard was like “Oh this guy is a journalist? Lets
googlebaidu what he writes- Oh it’s just sinophobic nonsense. Tell him he has to come back tomorrow so we can waste more of his time”
