A year after the fact, another death has been attributed to the explosion of a defective Takata airbag. This time, the car was not even on the road.

Honda said Monday that the victim was using a hammer to repair a 2001 Accord parked at a home near Miami in June 2016. The company said it did not know what repairs were being attempted, but said the ignition switch was in the “on” position.

Eventually, the person activated the airbag inflater, which ruptured as the bag blew up, according to Honda. The individual, who did not own the Accord, died the next day.

The fatality was the 12th in the United States linked to Takata’s airbag inflaters, according to the National Highway Traffic Safety Administration, and underscored the danger still posed by the faulty devices despite a widespread recall of vehicles using them.
