1Proximity to flammable materials On top of the appliance
2Hot surfaces Air vent, ventilation port, appliance door and
cooking chamber
3Hot steam / vapour Air vent, ventilation port, cooking chamber
4Hot liquids Cooking chamber
5Contact with cleaning agents Cooking chamber, cleaning-fluid connection
6Spraying down the appliance with water Appliance case (cover for electrical parts)
7Break in the cold chain (no picture)
