The briode nebuliser was a component of the Kartz-Reimer module. The Sixth Doctor sabotaged the module by paring the briode nebuliser's interface. He left a thin membrane of the interface so it would only work once, which ensured the survival of Peri Brown when she was forced to take the module on a test journey. As a result of the Doctor's sabotage, the module exploded on its second use, killing its occupant Chessene of the Franzine Grig.

Upon learning of the Sixth Doctor's sabotage, the Second Doctor remarked that it was precisely what he would have done. (TV: The Two Doctors)
