Understanding Airbags and Deployment Triggers

Airbags are inflatable cushions that quickly deploy from compartments in the dashboard, steering wheel, and side panels of a vehicle during a collision. These devices are activated by sensors that detect a sudden deceleration, such as during a frontal, side, or rear-end impact. When these sensors trigger the airbag system, a chemical reaction releases nitrogen gas, rapidly inflating the airbag and creating a protective barrier between the occupant and the interior of the car.

Consequences of Deployed Airbags

Deployed airbags, while providing protection during an accident, can also create additional challenges. The force of the airbag deployment can cause injury if not properly restrained, and the chemical reaction that inflates the airbag releases a fine dust that can irritate the eyes and airways. Additionally, deployed airbags must be repaired or replaced to maintain the vehicle’s safety features.
