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.
WARNING: Several air bag system components get hot after
inflation. Do not touch them after inflation.
WARNING: 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),
• seat-mounted side airbags. Refer to Seat-mounted side airbag system
later in this chapter
• Safety Canopy system. Refer to Safety Canopy system later in this
chapter.
