Airbags are designed only to deploy during a crash. An undeployed airbag is very unlikely to injure a rescuer unless the vehicle is subject to significant force such as cutting or bending the metal body. As soon as practical the battery of a crashed vehicle should be disconnected by an experienced person. This reduces the risk of both fire and accidental airbag activation. In assisting a patient inside a crashed vehicle an undeployed airbag should be regarded as a hazard similar to broken glass or sharp metal edges. It is prudent to avoid contact or close proximity with an undeployed airbag in the same way that it is prudent to avoid contact with broken glass.
