72 00 ... Safety regulations for handling components with gas generators
It is essential to comply with the regulations as specified in the law relating to the use of explosives when working on airbag units and seat belt tensioners.
Airbags, seat belt tensioners etc. are pyrotechnical objects. Pyrotechnical objects are assigned to different danger classes on the basis of the quantity of propellant that they contain. The assignment can be ascertained from the identification marking on the product
| IMPORTANT | Failure to comply with the warning notices and repair instructions for gas generator components can cause accidental deployment and result in injury and vehicle damage! |
This applies in particular to the following components
- Airbag modules (driver's/front passenger airbags, side airbags)
- Buckle/belt tensioner
- Head airbag (ITS, AHPS)
- Active knee protection
- Active head restraint
- Safety battery terminal (SBK)
- Regulations The regulations quoted in the following refer to the Federal Republic of Germany. In all other countries, the relevant legislation and regulations must be observed in each case. Country-specific legal regulations that go beyond this information or court decisions based thereon must be followed in each case or given precedence over these regulations. The following components used by BMW: Pyrotechnical restraint systems are subject to danger class PT1 Gas generators are pyrotechnical objects belonging to danger class T1. Handling, transporting and storing non-fired gas generators are subject to the "Explosive Materials Act" (law relating to the use of explosives dated 13/09/1976). The relevant trade supervisory authority must be notified at least 2 weeks before pyrotechnical objects are handled for the first time. Here the relevant authority must be notified in writing of the person responsible (e.g. dealership owner, holder of general power of attorney or if necessary workshop supervisor). A certificate of qualification, i.e. specific training, is not required for the person responsible.
- Disassembly and assembly Inspection, testing and installation work may only be carried out by expert trained personnel in BMW Service. Work on components of the airbag system should only ever be carried out with the battery disconnected, the negative terminal post covered and the plug connection of the cable leading to the gas generator disconnected. If only the battery is disconnected, the following prescribed waiting period must be observed without fail: 30 minutes for vehicles up to 9/93; 1 minute for vehicles from 9/93 In the event of breaks in work, a component with a gas generator that has been removed must be secured against access by other persons. Individual components must never be repaired. Instead, always replace them. Do not treat airbag system components with cleaning agents or grease. Components of the airbag system must not be exposed to temperatures in excess of 75 °C. Airbag system components, including electronic diagnostic components, which have been dropped from heights in excess of 0.5 m must not be reinstalled in the vehicles. Before installing, subject airbag system components (including electronic diagnostic components) to a visual inspection for damage and replace if necessary. Airbag system components may only be electrically tested while they are installed and only with the BMW diagnostic system / DIS. Danger of injury: The airbag module may only be set down with the airbag itself facing upwards . Otherwise the generator will be thrown upwards if it is fired. Do not point the firing pellet of a gas generator at other persons. Components with gas generators must not be fired while they are removed. They must be disposed of by special disposal companies or returned to BMW in the packaging of the new components. When carrying out straightening and welding work with an electric welder: Disconnect battery Cover negative terminal (post) Avoid all contact with the skin when removing a fired airbag module - wear gloves. Wash with water after contact with the skin.
- Transport Components with gas generators must be sent off in the packaging of the new components.
- Storage Observe the regulations of the relevant trade supervisory authority and the applicable national regulations.

72 11 ... Checking automatic safety belt
General considerations when checking seat belts
The seat belts must be checked after an accident.
For the check, you should start by trying to get information on which seats in the car involved in the accident were occupied. If this is not possible, check all the seat belts in the car and replace them if necessary.
In the event of deformations on the car, you must subject the components of the restraint system affected in this area such as e.g.
- Seat belt
- Seatbelt height adjustment
- Belt buckle tensioner
- Triggering sensors
- etc.
to a function check and a visual inspection.
If you are in any doubt as to the unimpaired functional capability of restraint system components, these components must be replaced in the interests of safety!
If a seat belt has to be replaced following an accident (e.g. in the event of a frontal and/or side impact with permanently deformed impact dampers/deformation elements or cross-members), the complete seat belt must be replaced! The complete seat belt comprises
- Top belt
- Lower strap
- Seat belt buckle (buckle tensioner)
- Seatbelt height adjustment
- Retaining screws of all components
The following must also be checked and if necessary replaced
- Seatbelt mountings on the car body
- Seatbelt mountings on the seat
- seat runners.
- Seat structure (frame, etc.)
Alignment tests on the seat and the seat runners are not permitted!
The following explanations and the checklist for the automatic safety belt can provide help.
An unusable seat belt or a seat belt worn in a serious accident should be destroyed immediately after removal to guarantee that it cannot be used again.
Checking automatic reel and seatbelt strap
The automatic reel has two independent activation systems for seat-belt locking.
The first activation system locks the automatic reel when driving quickly around curves, driving in tight curves, on extreme inclinations (vehicle rolls over) and during sharp braking or impact.
To check, the seat backrest must be placed in the upright position and both hands held in a supporting position close to the steering wheel. The brakes are then applied fully while driving on a dry surface and at a road speed equal to twice that of walking speed.
The seat belt must lock.
The second activation system provides additional safety and is controlled by inertia mass.
If the reel locks when the strap is pulled out suddenly, this system is also OK.
Automatic reel does not require servicing and must not be opened.
Precondition for complete, problem-free retraction of straps
- the straps must not be twisted!
- the straps must not be damaged!
When placed to one side, the straps of the front seats must retract fully.
With the straps in the rear seat bench, a small remaining loop is acceptable due to increased friction between the strap and the rear seat bench cover if
- this remaining loop is fully retracted when the strap is reguided.
Belt straps should only be cleaned with a luke-warm soap solution or a commercial laundry detergent.
Belt straps must never be cleaned chemically or dyed.
The automatic reel and strap must be replaced in the event of
- creases
- unraveling
- pinches
- cracks and tears
- traces of melting
- traces of wear on casing of seat belt tongue or on reversing clip.
Checking lower strap (belt buckle tensioner)
To fasten a seat belt, the tongue should insert easily and with a loud click in the lock.
When the "Red button" is pressed, the tongue must be ejected from the lock under spring pressure.
If the lock cover is missing or damaged, the lower strap must be replaced.
Replace the triggered belt buckle tensioner including the complete seat belt with seatbelt height adjustment and retaining screws and check the
- Seatbelt mountings on the car body
- Seatbelt mountings on the seat
- seat runners.
- Seat structure.
Criteria for a triggered mechanical belt buckle tensioner
- very low position of seatbelt buckle (comparisons with new part).
Criteria for a triggered pyrotechnical belt buckle tensioner
- very low position of seatbelt buckle (comparisons with new part).
- Airbag warning lamp permanently lit: read out airbag system fault memory.
The belt buckle tensioners can be triggered under certain circumstances even when the seat is not occupied. If it is definite that the belt system was not used (seat was not occupied), there is no need to replace the
- upper strap
- attachment parts (belt height adjustment, screws)
- seatbelt mountings on the car body
- Seatbelt mountings on the seat
- seat runners.
after a check.

72 12 ... Notes on scrapping vehicles with gas generators (airbag system)
The gas generator is a pyrotechnical component and is for the most part permanently mounted on the following components
- Airbag module Driver's/passenger airbag Side airbag Head airbag (e.g. AHPS2) Knee airbag
- Belt tensioner
- Belt buckle tensioner
- Safety battery terminal
- Active head restraint
In accordance with accident prevention regulations and specific national regulations, gas generators must be rendered unusable before they are scrapped. This is necessary because pyrotechnical objects can cause injury if improperly activated (e.g. scrapping with flame cutters).
With vehicles which are scheduled for scrapping, it is always essential prior to draining and further stripping work to ensure that all the gas generators in the vehicle are fired. The fired gas generators can then be scrapped together with the vehicle.
Gas generators that have not fired constitute a hazard (also to the environment)!
Firing failure
If correct firing is not possible, the relevant components must be removed and disposed of by special waste disposal companies!
Comply with Safety regulations for handling airbag system components.
If a firing operation has failed
- Disconnect the firing device from the battery and
- Only approach the vehicle after a few minutes have elapsed
The components of an airbag system must always be disposed of. Such components must not be sold on as used parts.
Firing
Firing of the gas generators may only be carried out by expert personnel and under the supervision of a responsible person. Other standard accident prevention regulations (safety goggles, ear defenders etc.) must also be observed.
The gas generators must be fired from the outside in this vehicle which has been earmarked for scrapping. In this process
- the doors must be closed
- the rear lid must be open
- the side windows must be open and
- the sunroof must be open
To fire the gas generators, use the firing device with the appropriate cables (follow instructions).
| WARNING | Once gas generators have been fired, observe a ventilation period of 10 minutes with the doors opened. Only then is it permitted to continue work inside the vehicle. Wear protective goggles and protective gloves when handling a fired gas generator! The burning of solid fuel will heat up the airbag unit - danger of burning hands! Wash skin with water after contact with fired gas generators! |
