The air bags inflate and deflate
rapidly upon activation. After air bag
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
air bag. 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, it may also
cause minor abrasions, swelling or temporary hearing loss. Because air
bags 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 air bag
deployment. Thus, it is extremely important that occupants be properly
restrained as far away from the air bag module as possible while
maintaining vehicle control.
Several air bag system components get hot after inflation. Do not
touch them after inflation.
If the air bag has deployed, the air bag will not function
again and must be replaced immediately. If the air bag is not
replaced, the unrepaired area will increase the risk of injury in a
collision.
The SRS consists of:
• driver and passenger air bag modules (which include the inflators and
air bags),
• one or more impact and safing sensors, passenger air bag deactivation
switch and diagnostic monitor (RCM)
• a readiness light and tone,
• and the electrical wiring which connects the components.
