Keep your face away from welding fumes and gases.
Fumes and hazardous gases

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 toxic emission values should be compared with the permissible limit
values.
The following components are responsible, amongst other things, for the degree
of toxicity 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
identifying working conditions can be found on the European Welding Associ-
ation website under Health & Safety (https://european-welding.org).
Flammable vapours (e.g. solvent fumes) should be kept away from the arc's radi-
ation 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 sealed tanks, vessels or pipes unless these have been prepared in accord-
ance with the relevant 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.
Dangers from
An electric shock is potentially life threatening and can be fatal.
