Asthmatics who stay in their car after a crash have been known to experience asthma attacks. One might chalk this up to stress, but something else is to blame: the aerosol compounds that are released into the cabin when an airbag inflates.
A group of researchers at General Motors confirmed this effect in the mid-1990s. Two dozen asthmatics each sat for 20 minutes in the backseat of an airtight car after an airbag was deployed, and 10 of them had significant reactions in their lung passages.
