Danger of injury when welding

DANGER

Risk of fatal injury from high voltage during electric welding!

Danger of explosion and fire when welding in the area of highly inflammable materials.

• 

Irritation to respiratory tracts from toxic zinc oxide emitted when welding galvanised steel!

• 

Danger of injury from unintentional triggering of pyrotechnical safety components!

• 

Danger of injury from weld spatters and UV light when welding!

• 

→ Do not perform welding work in a damp environment or on wet ground; there is a risk of fatal

injury from the voltage being conducted through the human body. Persons with heart pacemakers
should not perform welding work. Use insulating underlays.

→ Remove highly flammable materials from the work area; if necessary, remove units with

fuel-carrying parts and protect work areas in the vehicle that are at risk of catching fire using
fire-proof covers.

→ Ventilate the work area well.

→ Remove smoke gases with a suitable extraction system (refer to Workshop Equipment Manual).

→ Wear suitable protective equipment, such as protective clothing, gloves, a welding shield and, if

necessary, a protective mask.

→ For welding work, always disconnect both terminals on the battery. In the case of welding work in

the immediate vicinity of the control modules for pyrotechnical safety systems, remove the control
modules before beginning work.
