The airbags inflate and deflate
rapidly upon activation. After airbag
deployment, it is normal to notice a
smoke-like, powdery residue or
smell the burnt propellant. This may
consist of cornstarch, talcum
powder (to lubricate the bag) or
sodium compounds (e.g., baking
soda) that result from the
combustion process that inflates the
airbag. Small amounts of sodium
hydroxide may be present which
may irritate the skin and eyes, but
none of the residue is toxic.
While the system is designed to help
reduce serious injuries, contact with a
deploying airbag may also cause abrasions, swelling or temporary hearing
loss. Because airbags must inflate rapidly and with considerable force, there
is the risk of death or serious injuries such as fractures, facial and eye
injuries or internal injuries, particularly to occupants who are not properly
restrained or are otherwise out of position at the time of airbag deployment.
Thus, it is extremely important that occupants be properly restrained as far
away from the airbag module as possible while maintaining vehicle control.
Several air bag system components get hot after inflation. Do not
touch them after inflation.
If the airbag has deployed, the airbag will not function again
and must be replaced immediately. If the airbag is not replaced,
the unrepaired area will increase the risk of injury in a collision.
The SRS consists of:
• driver and passenger airbag modules (which include the inflators and
airbags),
• one or more impact and safing sensors and diagnostic monitor (RCM),
• a readiness light and tone
• the electrical wiring which connects the components.
The RCM (restraints control module) monitors its own internal circuits
and the supplemental airbag electrical system wiring (including the
impact sensors, the system wiring, the airbag system readiness light, the
airbag back up power and the airbag ignitors).
