Gas Laws Save Lives: The Chemistry Behind Airbags

potentially life-saving decisions about using airbags. Overview of How Airbags Work Timing is crucial in the airbag's ability to save lives in a head-on collision. An airbag must be able to deploy in a matter of milliseconds from the initial collision impact. It must also be prevented from deploying when there is no collision.
