Airbags expand through a rapid chemical reaction that produces gas when triggered by a collision. Sensors in the vehicle detect the impact and send a signal to ignite a propellant, typically sodium azide, which decomposes to generate nitrogen gas. This gas inflates the airbag within milliseconds, creating a cushion to protect occupants during a crash. The entire process is designed to occur quickly to minimize injury.
