Airbags themselves are powered by explosives. Bet you didn’t know that, in fact there working mechanism is somewhat similar to a rocket engine. Airbags utilize the power of explosion to save your life.In order to allow airbags to help a passenger, they have to be deployed faster than the speed of the car. A typical airbag gets deployed within 20 milliseconds of the noted impact.
Airbags are connected to an accelerometer sensor, which is independent of your car’s speedometer.It is calibrated to monitor extremely sudden drops in speed and will not trigger the airbags in case of sudden hard braking.
In fact, the system is so efficiently calibrated that it can calculate the drop in speed and the actual time that the car will come to a halt in a matter of milliseconds.
When a speeding car hits an object and crashes, the airbag sensors would know exactly when to fire the system. The sensors are connected to heating coils which would ignite the explosive at the right time creating a controlled explosion. This explosion will then fill the airbag with harmless gases which would act as a cushion to the impact.
Sounds simple. Right? How can it kill a man then? Actually, it can if caution is not practiced. You see airbags deploy at a speed of 300 Km/Hr. Yes, 300! Things are really fine if you are wearing a seat belt and nothing comes in between you and the bag. Even an object like a cell in between can kill you as the forces in play are really huge.
This is the exact reason why small kids should never travel in the front seats of a car which has airbags. Even with seatbelts owing to their small height the kids can due to the dual impact at the wrong place.
So here you have your answer, improper use of airbags can definitely kill you.
