Blazing Hell (焦熱地獄 Shōnetsu Jigoku?, Inferno Hell in the Viz Manga) is the fourth level of Impel Down in which prisoners are kept. At this level, a pool lies filled with boiling blood heated by a raging fire making it extremely hot. The heat caused by this is so intense that it also heats up the level directly above it. If one tries to jump down to this level from Level 3 using the large hole used for ventilation above but don't land in a safe place, then they will die.
Prisoners from other levels are regularly tortured here. The most prevalent form of torture however is being thrown into the gigantic pot of boiling blood in the middle of the level.
Daz Bones was kept here, though he was shown to be unfazed by the heat of this level while being placed into hard labor. He also saw Luffy and Magellan's battle while in his cell.
Magellan, the warden of Impel Down, stays here. His office contains a lift, which can take several people to all the levels throughout the fortress, bypassing the stairs. This is also where the kitchen of the prison is located, right next to Magellan's office. Luffy's battle with Magellan was fought here prior to him being completely poisoned and captured.
