I was preparing homemade french fries for my son as an after-school snack. I overloaded the fryer basket and it slipped out of my hand and back into the boiling oil, splashing all over the inside of my forearm. I had on hand some medical grade burn cream (from my prep supplies) and applied it after run cold water over the area for a few minutes. It healed completely but I got rid of the deep fat fryer.
I was cleaning sticky oil from my cabinets and drawers for days.
When I was in College, I worked at a McDonald’s in Maryland in the summer of 1986. I occasionally worked the french fry machines, and the lard — yes, we used lard at the time — would pop and occasionally get on my skin and burn it. Then, when I reached under the warming light to get fries for somebody, the warming light would burn the area all over again.
My boss got severely burned while making peanut brittle over Christmas some years ago, and was hospitalized for a few days.
