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:
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)
Head airbag (ITS, AHPS)
Active knee protection
Active head restraint
Safety battery terminal (SBK)
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.
2. 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
