Module

From Tardis Wiki, the free Doctor Who reference

Modules were furnaces within each overflow camp that burnt the bodies of category one patients, who had been deemed dead.

Colin Maloney trapped Vera Juarez within one and burnt her to prevent her from leaking information about treatment at the camp. (TW: The Categories of Life)

Geraint Cooper was scheduled to be incinerated inside a module, as he had suffered from a fatal heart attack. However, Geraint was rescued by his daughter, Gwen, who later blew another module up. (TW: The Middle Men)
