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
