Burns and scalds — hot surfaces, liquids, steam, oil
Fryers, ovens, grills, coffee-machine steam wands, carrying hot liquids through service areas. Moving or changing hot oil is the one you already treat carefully — worth stating is why it's absolute: at around 180°C a spill is a deep burn before you can react, which is why it's changed cold or moved with transfer gear, never carried hot in the open.
This is one hazard. Your register is the set that applies to you — under 20 questions, about five minutes, free.
