IMPORTANT:

z

The rapid expansion of gas involved with deploying an inflator 
module is very loud. Notify all people in the immediate area that an 
inflator module will be deployed.  

z

When the inflator module deploys, the deployment fixture may jump 
vertically. This is a normal reaction of the inflator module due to the 
force of the rapid expansion of gas inside the inflator module.
