How does the airbag supplemental restraint system work?
The airbag SRS is designed to
activate when the vehicle sustains
sufficient longitudinal deceleration.
The fact that the airbags did not
inflate in a collision does not mean
that something is wrong with the
system. Rather, it means the forces
were not of the type sufficient to
cause activation. Airbags are
designed to inflate in frontal and
near-frontal collisions, not rollover,
side-impact, or rear-impacts.
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, it may also
cause minor 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.
