A woman was killed in her home and four other people were injured when a truck carrying Takata airbag parts and explosives crashed and detonated on a Texas road last week, the company and local authorities confirmed on Monday.

The immense blast — the victim’s remains were not located for two days — highlighted the potency of the explosives used by Takata in its airbags as a propellent to activate its bags in a car crash. It also pointed to the risks associated with Takata’s transport of the explosives across the country from a propellant factory in Washington State to Mexico.

Takata’s airbags, and the explosive material used to make them, are at the center of the largest auto safety recall in history. Takata airbags installed in automobiles can explode violently when activated, and have been linked to the deaths of at least 14 drivers as well as to the injuries of over 100 people. Fourteen automakers have recalled more than 64 million inflaters over the defect.

The airbags use a propellant based on ammonium nitrate, which has come under scrutiny for its tendency to break down over time and combust violently when triggered.
