Pyrotechnic Belt Tensioners, Disposal
-
The scrapping of gas generators which have not been triggered represents a hazard.
-
In line with the relevant accident prevention regulations, the gas generator of the belt tensioner unit must be rendered inoperable before scrapping.
-
This is necessary because pyrotechnic devices can cause injury if disposed of incorrectly (e.g. using a blow torch).
-
Seat belts which need to be removed (e.g. after an accident in which the belt tensioner was not activated) must be triggered before removal.
-
This does not apply to malfunctioning seat belts (sticking, failure to retract) which are required for factory analysis.
-
Observe regulations governing transportation of explosive substances.
-
Procedure for triggering front pyrotechnic belt tensioners:
NOTE:
-
Whenever possible, pyrotechnic belt tensioners must be deployed outside the vehicle. Use Airbag and Pyrotechnic Deployment Device J-44210.
-
The procedure that follows is for deployment of tensioners mounted inside a vehicle.
