Safety Precautions When Working On Vehicles With Natural Gas Fuel Systems

WARNING: This page is about a different car, the 2020 Audi A4, 2019 Audi A4, 2018 Audi A4, and 2017 Audi A4. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:

Extremely dangerous and risks of explosion due to gas leaking out making contact with ignition sources and due to electrostatic discharge.

Death or serious bodily injury by explosion.

  • Never work on natural gas systems which have flowing noise which is readily noticeable.
  • Never drive vehicles into the workshop which have a flowing noise which is readily noticeable.
  • Park vehicles where a flowing noise is readily noticeable, in open air and create a secure area.
  • Have a specially technically trained person perform the work on the natural gas system.
  • Preform a leak test after working on the natural gas system.
CAUTION:

Extremely dangerous and risks of explosion due to gas leaking out

Extremely dangerous and risks of explosion due to static discharge and ignition sources near the natural gas system. Escaping natural gas can escape and cause an explosion.

Death or serious bodily injury by explosion.

-- Wear protective work clothing with at least 35 % cotton content.

-- Wear safety gloves with at least 35 % cotton content.

-- Wear protective footwear.

Danger of frostbite due to escaping natural gas

In the natural gas high pressure area, natural gas can escape uncontrolled.

Frostbite on the hands and other parts of the body is possible.

-- Reduce the pressure before working on the natural gas system in the high pressure area.

 

-- Remove the pressure in the natural gas high pressure line. Refer to appropriate service information. .
