I did something similar when I was on a prep line. We had pump nacho cheese sauce that came in powdered form. The proper way to heat it up was to mix it and pour it into small containers to microwave individually.

Ain’t no one got time for that shit in a restaurant, so we just set the metal container for the pump in the fryer. Well, one day I was removing the container and it tipped just a bit so the cheese water hit the oil and threw it all over my hands.

Luckily I had the presence of mind to hold on and remove it instead of dumping the entire thing in. And luckily I had thin gloves on that stopped my burns at second degree, but boy was the owner worried about a lawsuit. He sent me across the street to Walmart with his credit card to get medical supplies.
