Which safety practice is essential when welding near airbag modules to prevent accidental deployment?

• A. Leave the battery connected and seal the area
• B. De-energize electrical systems, disconnect the battery, avoid energized devices, and wear PPE
• C. Ignore arcing distance and use bare hands
• D. Increase welding current to 'burn off' the module

Answer: (B)

Preventing accidental airbag deployment during welding comes down to removing all electrical energy from the airbag system and protecting yourself from the welding arc. Airbag inflators contain pyrotechnic charges that can be triggered by electrical signals or heat, so the safest practice is to de-energize the vehicle’s electrical systems and disconnect the battery before you start, ensure any capacitors in the airbag circuit are discharged, keep energized devices away, and wear appropriate PPE for welding. By cutting power and isolating the system, you eliminate the pathways that could fire the inflator or suffer EMI that might affect the module. Wearing PPE such as a welding helmet, gloves, flame-resistant clothing, and eye protection adds a layer of protection against sparks and any surprises near the module. This approach is essential because it directly reduces the risk of unintended deployment during welding, grinding, or cutting near airbag components. Leaving the battery connected and sealing the area keeps the system energized and ready to deploy, which is unsafe. Using bare hands and ignoring arc distance is reckless and hazardous. Trying to burn off the module by increasing welding current is dangerous and ineffective.
