Disposal

Disposal of Deployable Devices and Pyrotechnic Devices That Are Undeployed-Inoperative

NOTE: All inoperative airbags, seatbelt pretensioners and inflatable seatbelt inflators have been placed on the Mandatory Return List. Treat all discolored or damaged airbags the same as any inoperative live airbag being returned.

1.   WARNING: Before beginning any service procedure in this manual, refer to health and safety warnings in section 100-00 General Information. Failure to follow this instruction may result in serious personal injury.

1. Depower the SRS
   Refer to: Supplemental Restraint System (SRS) Depowering (501-20B Supplemental Restraint System, General Procedures).
   

1. Remove the undeployed/inoperative device. Refer to the appropriate procedure in this section or in the seatbelt system section.
   

1. NOTE: When installing a new airbag or inflatable seatbelt inflator, a prepaid return postcard is provided with the replacement part. The serial number for the new part and the VIN must be recorded and sent to Ford Motor Company.

   If installing a new airbag, or inflatable seatbelt inflator, record the necessary information and return the inoperative airbag to Ford Motor Company.
   

Disposal of Deployable Devices and Pyrotechnic Devices That Are Deployed

1. Depower the SRS .
   Refer to: Supplemental Restraint System (SRS) Depowering (501-20B Supplemental Restraint System, General Procedures).
   

1. Remove the deployed device. Refer to the appropriate procedure in this section or in the seatbelt system section.
   

1. NOTE: If a dual stage driver or passenger airbag has deployed due to a crash event, the airbag requires manual deployment to make sure both stages and the active canister vent (if equipped) have deployed before scrapping the vehicle or disposing of the airbag.

   Determine if the vehicle is equipped with dual stage driver or passenger airbags.
   Refer to: Airbag and Seatbelt Pretensioner Supplemental Restraint System (SRS) - Component Location (501-20B Supplemental Restraint System, Description and Operation).

   • If required, dispose of in accordance with local contaminated waste regulations.
     
   • If there are no local contaminated waste regulations, dispose of the deployed device in the same manner as any other part to be scrapped.
     

Disposal of Deployable Devices and Pyrotechnic Devices That Require Manual Deployment

NOTE: Safety and environmental concerns require consideration and treatment of restraints system deployable and pyrotechnic devices when disposing of vehicles, deployable devices or pyrotechnic devices. Deploying deployable and pyrotechnic devices before scrapping a vehicle or the device eliminates the potential for hazardous exposures or reactions during processing. If special handling procedures are followed, deployable and pyrotechnic devices can be deployed safely and recycled with the vehicle, shipped separately to a recycling facility or disposed of safely.

1. To determine the deployable devices a vehicle is equipped with:
   Refer to: Airbag and Seatbelt Pretensioner Supplemental Restraint System (SRS) - Component Location (501-20B Supplemental Restraint System, Description and Operation).

   • Inflatable seatbelt inflators
     
   • Knee airbag
     
   • Passenger airbag
     
   • Seat side airbag

If a dual stage driver or passenger airbag has deployed due to a crash event, the airbag requires manual deployment to make sure both stages and the active canister vent have deployed before scrapping the vehicle or disposing of the airbag. Refer to Driver, Passenger, Knee, Side Curtain and Seat Side Airbags - Remote Deployment in this procedure.
   

Driver, Passenger, Knee, Side Curtain and Seat Side Airbags - Remote Deployment

NOTE: For airbags with multiple loops, deploy all of the loops on the airbag.

NOTE: Some driver and passenger front airbags have 2 deployment stages and an active canister vent. After a collision it is possible that Stage 1 has deployed and Stage 2 and the active canister vent have not.
