Safety measures when working with pyrotechnic components

Warning

Pyrotechnic components always contain a propellant that generates a gas during combustion. On some versions, a separate compressed gas reservoir is available to generate the gas.
This compressed gas is stored under high pressure in a compressed gas tank.
Ignition of the pyrotechnic components is by means of an electric/mechanical igniter.
Testing, removing, installing and repair work may only be performed by qualified personnel.
For airbag units, there are no exchange intervals.
Under no circumstances should checks be carried out with a test lamp, voltmeter or ohmmeter.
Pyrotechnic components may only be checked in installed state and with vehicle diagnosis, testing and information systems approved by the manufacturer.
When working on pyrotechnic components and airbag control unit - J234-, the battery earth strap must be disconnected with the ignition switched on. Then cover negative terminal.
A waiting time of 10 seconds is necessary after disconnecting the battery.
6R 2009–2014 The battery must be connected with the ignition SWITCHED ON. When doing this, there should be no-one inside the vehicle. Exception: Vehicles with battery inside passenger compartment. In this case do not stay anywhere near the effective range of the airbags and seat belts.
Wash hands after coming into contact with triggered pyrotechnic components of restraint system.
Pyrotechnic components must not be opened or repaired; always use new parts (risk of injury).
Pyrotechnic components which reveal damage must not be installed.
Pyrotechnic components that have been dropped onto a hard surface must not be installed.
Before handling pyrotechnic components of the restraint system, for example before separating an electrical connection, the mechanic must electrostatically discharge himself/herself. Electrostatic discharge is achieved by touching earthed metallic parts, such as the door striker plate.
Pyrotechnic components must be installed immediately after they have been removed from their packaging.
If work is interrupted, the pyrotechnic component must be stored back in its packaging.
Leaving the pyrotechnic component unattended is prohibited.
