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, contact with a deploying air bag may also cause
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 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 air bag electrical system wiring (including the
impact sensors, the system wiring, the air bag system readiness light, the
air bag back up power and the air bag ignitors).
