The PSDI-5 PSAN airbag inflator is a desiccated inflator. Desiccated inflators contain calcium sulfate the purpose of which is to prevent the ammonium nitrate inside the airbag to deteriorate in case of humidity or high temperature. The ammonium nitrate is the most important component of the airbag. It inflates the airbag in case of an accident. If the ammonium nitrate deteriorates, the airbag may not inflate proprely and may explode causing potential injury or death to the car driver and the passengers.
In its report to the National Highway Traffic Safety Administration (NHTSA) Takata indicates that the PSDI-5 PSAN airbag inflator posed a potential risk to the car occupants. When testing the inflator, Takata found that the amonium nitrate used to inflate the airbag was showing signs of deterioration and could lead to a breakage over time. However Takata also indicates that so far in all the testing conducted none of the inflators tested broke off.
The announcement by Takata raised doubt about the safety of its other airbag inflators using calcium sulfate as a desiccant. Senator Bill Nelson from Florida asked the NHTSA to act fast and to take immediate measures to test all other dessciated inflator models manufactured by Takata.
Recently another death related to a defective Takata airbag explosion was announced in the media. The accident occurred a year ago but the cause was only recently attributed to a defective Takata airbag. A man in Florida was repairing a car parked at his home last June when the airbag violently exploded and injured the man. He died from his injury at the hospital a day after the accident. The victim is the 17th person to die after being injured by the explosion of a defective Takata airbag.
Before the latest announcement, the Takata recall previously included 69 million inflators in 42 million vehicles. It is the biggest recall in the automotive industry. As a result Takata had to file for bankruptcy in the US and in Japan.
