5) After air bag module deploys, let it cool off and allow
dust to settle for at least 30 minutes before approaching. Tightly
seal deployed air bag module in a strong vinyl bag and dispose of air
bag as you would any other part.
DEPLOYED AIR BAG CLEAN-UP
WARNING: Vehicle interior will contain sodium hydroxide powder, a
by-product of air bag deployment. Since this powder can
irritate skin, eyes, nose and throat, wear safety glasses,
rubber gloves and long-sleeved shirt during clean-up.
1) Avoid breathing powder from air bag deployment. Begin
clean-up by putting tape over air bag exhaust vent to prevent
additional powder from escaping into vehicle interior. Use a vacuum
cleaner to remove any residual powder from A/C-heater outlets and
vehicle interior.
2) Turn blower motor to low for a few minutes and exit
vehicle. Turn blower motor off. Vacuum any other powder expelled from
plenum. Vacuum interior a second time to recover all powder. Avoid
kneeling or sitting on unclean areas. Wrap deployed air bag in heavy
vinyl plastic and dispose of it as you would any other part.
