Chemistry Behind Airbags

Sodium azide (NaN 3) can decompose at 300 o C to produce sodium metal (Na) and nitrogen gas (N 2). The signal from the deceleration sensor ignites the gas-generator mixture by an electrical impulse, creating the high-temperature condition necessary for NaN 3 to decompose. The nitrogen gas that is generated then fills the airbag.
