Safety Precautions When Working With Pyrotechnic Components

CAUTION:
  • Pyrotechnic components always contain chemicals, which turn into an expanding gas when detonated. There is also additional stored gas available for discharge.
  • This gas is contained under high pressure and is stored in a pressurized gas container.
  • An electric/mechanical igniter ignites the pyrotechnic components.
  • Testing, assembly, and repair work may only be performed by qualified personnel.
  • There is no change interval for airbag units.
  • Never test with a test light, volt meter or ohm meter.
  • The pyrotechnic components may be checked only when they are installed and with a manufacturer approved Vehicle Diagnostic Tester.
  • When working on pyrotechnic components and on the Airbag Control Module -J234-, the battery ground cable must be disconnected when the ignition is switched on. Then cover the negative terminal.
  • Wait for 10 seconds after disconnecting the battery.
  • The ignition must be SWITCHED ON when connecting the battery. Nobody should be inside the vehicle when doing this. Exception: Vehicles with the battery inside the vehicle interior. In this case, stay away from the airbags and the safety belts.
  • Wash hands after touching ignited restraint system pyrotechnic components.
  • Pyrotechnic components may not be opened nor repaired; always use new parts (risk of injury).
  • Pyrotechnic components that have fallen onto a hard surface or show signs of damage must not be installed in the vehicle.
  • The technician must discharge static electricity before handling pyrotechnic components for the restraint system, for example, before disconnecting the connector. Touching grounded metal parts will discharge the static electricity, for example by touching the door striker.
  • Pyrotechnic components should be installed immediately upon removal from shipping package.
  • If the procedure must be stopped for awhile, put the pyrotechnic component back into its shipping package.
  • It is not permitted to leave a pyrotechnic component out unattended.
  • Do not use any grease, cleaning solutions or similar substance on pyrotechnic components.
  • Pyrotechnic components must not be exposed to temperatures over 100 °C (212 °F), even for a short time.
