SUPPLEMENTARY RESTRAINT SYSTEM (SRS) 5 1.4. DISPOSAL OF FAULTY AIR BAG UNIT Airbags that have not been safely deployed can cause severe injury to humans & a significant damage to equipment. If special handling procedures are followed the airbags can be safely deployed & then all component parts can be properly recycled. DISPOSAL PROCEDURE NOTE: A. The disposal of AIR BAG module assembly shall be done in an area with adequate ventilation. B. A person handling any restraints module assembly shall have to wear ESD (electro-static discharge) straps to reduce any risk of inadvertent deployment. 1. Follow the guidelines for removal of AIR BAG module assembly as specified in workshop manual. If the module assembly is found defective before fitment on the vehicle, go to step 2 . 2. Wear adequate ear protection device (ear plugs), safety goggles and safety hand gloves. 3. Connect the specified connector to the restraints module assembly, with a pig-tail. 4. Clamp the restraints module assembly in a shop bench vise (or equivalent clamping mechanism). The clamping force should be adequate. 5. refer the following methods for clamping the different air bag modules on bench vise i. DRIVER AIR BAG (DAB) The steering wheel should be clamped in such a way that the DAB module should face upwards. ii. PASSENGER AIRBAG Airbag mounting bracket ( located on Cross Car Beam) used for mounting module on bench vice. iii. SEAT BELT (PRE-TENSIONER) Seat belt assembly can be directly held in bench vice. Seat belt webbing length could be cut prior to deployment. iv. Use a 2 core electrical wire at least 15m long. Use a short link at one end of the wire and then connect the other end to the module pigtail. 6. Place a vehicle battery or equivalent source at a distance of 15m from the restraints module assembly. The battery voltage shall be in the range of 8-16V. 7. Remove the short link before applying the voltage source. 8. Connect one core of the electrical wire to the positive (+ve) battery terminal. do not connect the other core with negative (-ve) battery terminal. 9. Make sure that no person is present within 15m radius of the "to be disposed" module assembly. 10. Connect the other core of the electrical wire with the negative (-ve) battery terminal for deployment of module assembly. 11. After deployment, wait for at least 10 minutes to ensure that none of the components within the module assembly is too hot. 12. Take out the deployed module assembly from bench vice and conduct suitable activities towards scrapping of the constituent components. Airbag module assemblies are generally made up of aluminum, stainless steel or mild steel, nylon, plastic etc. After the module assembly is removed from bench vise, the constituent components could be scrapped as per the guidelines/laws for non-hazardous waste materials.
