Seat Belt Systems: Service and Repair

Pyrotechnic Belt Tensioner, Disposal

NOTE: Whenever possible, pyrotechnic belt tensioners must be deployed outside the vehicle. Use Airbag and Pyrotechnic Deployment Device J-44210 and follow instructions in booklet.

WARNING:
- Gas generators which have not been ignited are a risk when scrapping.
- According to accident risk specifications gas generator for belt tensioner must be deployed before scrapping.
- This is necessary, because pyrotechnical material when activated improperly (e.g. scrapping with cutting torch) could cause injury.

CAUTION:
- All seat belts which are replaced (e.g. after an accident if belt tensioner is deployed) must be ignited before removal.
- Excluded are seat belts, which due to quality deficiencies (stick, do not roll up) are unused and are in the shop for analysis.
- Transport specifications for explosive materials.

NOTE: The procedure that follows is for deployment of tensioners mounted inside a vehicle.
