Ensure an adequate supply of fresh air. Ensure that there is a ventilation rate of at least
20 m³ per hour at all times.
Otherwise, a welding helmet with an air supply must be worn.
If there is any doubt about whether the extraction capacity is sufficient, the measured to-
xic emission values should be compared with the permissible limit values.
The following components are responsible, amongst other things, for the degree of toxi-
city of welding fumes:

The relevant material safety data sheets and manufacturer's specifications for the listed
components should therefore be studied carefully.
Recommendations for trade fair scenarios, risk management measures and for identify-
ing working conditions can be found on the European Welding Association website under
Health & Safety (https://european-welding.org).
Flammable vapours (e.g. solvent fumes) should be kept away from the arc's radiation
area.
Close the shielding gas cylinder valve or main gas supply if no welding is taking place.
Danger from fly-
Flying sparks may cause fires or explosions.
ing sparks
Never weld close to flammable materials.
Flammable materials must be at least 11 metres (36 ft. 1.07 in.) away from the arc, or
alternatively covered with an approved cover.
A suitable, tested fire extinguisher must be available and ready for use.
Sparks and pieces of hot metal may also get into adjacent areas through small gaps or
openings. Take appropriate precautions to prevent any danger of injury or fire.
Welding must not be performed in areas that are subject to fire or explosion or near sea-
led tanks, vessels or pipes unless these have been prepared in accordance with the rele-
vant national and international standards.
Do not carry out welding on containers that are being or have been used to store gases,
propellants, mineral oils or similar products. Residues pose an explosive hazard.
Risks from mains
An electric shock is potentially life threatening and can be fatal.
current and wel-
Do not touch live parts either inside or outside the device.
ding current
During MIG/MAG welding and TIG welding, the welding wire, the wirespool, the feed rol-
lers and all pieces of metal that are in contact with the welding wire are live.
Always set the wirefeeder up on a sufficiently insulated surface or use a suitable, insula-
ted wirefeeder holder.
