In her complaint, filed Wednesday [PDF], Ms. Manzi said the defective adapter ignited the oxygen in the mask she wore for her chronic obstructive pulmonary disorder, asthma, and emphysema. 
The complaint also alleged that Apple knew its adapter was defective, and was “prone to fraying, sparking, melting, and overheating through an extended warranty program in which customers who had “seen a spark” were advised they could receive a free replacement.”
