how air bag works in car?

0.03 SECOND is all it takes to inflate an air bag.

That's not the only chemistry involved. Notice that the other chemical into which sodium azide falls apart is Na, or sodium. Sodium is a very reactive metal that will react rapidly with water to form sodium hydroxide; as a result, it would be quite harmful if it got into your eyes, nose or mouth. So to minimize the danger of exposure, air bag manufacturers mix the sodium azide with other chemicals that will react with the sodium and, in turn, make less toxic compounds.
What prompts an air bag to inflate by way of this reaction? There are sensors in the front of the automobile that detect a collision. These sensors send an electric signal to the canister
