72 00... Safety regulations for handling components with gas generators

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

1. Regulations 

   Relevant legislation and regulations must be observed when handling airbag components.

2. Disassembly and assembly 
   • Inspection, testing and installation work should 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.
3. Transport 
   • Components with gas generators must be sent off in the packaging of the new components.
4. Storage 
   • Observe the regulations of the relevant trade supervisory authority and the applicable national regulations.
