• Any metal vapors, especially lead, cadmium, copper and beryllium are
harmful! Ensure sufficient ventilation or extraction. Do not exceed the
current MAC values.
• Rinse work-pieces that have been degreased with chlorinated solvents
with clear water. Otherwise there is a risk of phosgene gas formation.
For the same reason, no degreasing baths containing chlorine must be
placed in the vicinity of the welding area.
• In connection with various welding torches, there may be other hazards,
for example those caused by: electrical current (power supply, internal
circuit), welding spatter with regard to combustible or explosive materials,
UV radiation from the arc, smoke and vapors.
• Adhere to the general fire protection regulations and remove
inflammable materials from the surroundings of the welding work area,
prior to starting work. Even hours after finishing the welding work, there
is a risk of late ignition caused by sparks. Place appropriate fire
extinguishing equipment in the workplace within easy reach.
2.5
