Use at-source extraction source and a room extraction system.
If possible, use a welding torch with an integrated extraction device.
Keep your head out of the welding fumes and gases.
Take the following precautionary measures for fumes and harmful gases:
-
Do not breathe them in.
-
Extract them from the work area using appropriate equipment.
Ensure that there is a sufficient supply of fresh air. Ensure that there is a ventila-
tion flow rate of at least 20 m³ per hour.
Use a welding helmet with air supply if there is insufficient ventilation.
If there is uncertainty as to whether the extraction capacity is sufficient, com-
pare the measured toxic emission values against the permissible limit values.
The following components are factors that determine how toxic the welding
fumes are:
-
The metals used for the workpiece
-
Electrodes
-
Coatings
-
Cleaning agents, degreasers, and the like
-
The welding process used
Consult the corresponding material safety data sheets and manufacturer's in-
structions for the components listed above.
Recommendations for exposure scenarios, risk management measures and
identifying working conditions can be found on the European Welding Associ-
ation website under Health & Safety (https://european-welding.org).
Keep flammable vapors (such as solvent vapors) out of the arc radiation range.
When no welding is taking place, close the valve of the shielding gas cylinder or
the main gas supply.
Danger from Fly-
ing Sparks
Flying sparks can cause fires and explosions.
Never undertake welding near flammable materials.
Flammable materials must be kept at least 11 meters (36 ft. 1.07 in.) from the
arc or protected with a certified cover.
Keep suitable, tested fire extinguishers on hand.
Sparks and pieces of hot metal may also get into surrounding areas through
small cracks and openings. Take appropriate measures to ensure that there is no
risk of injury or fire.
Do not undertake welding in areas at risk of fire and explosion, or on sealed
tanks, drums, or pipes if these have not been prepared in accordance with cor-
responding national and international standards.
Do not undertake welding on containers in which gases, fuels, mineral oils, and
the like are/were stored. Residues pose a risk of explosion.
Risks from grid
current and
welding current
An electric shock can be fatal.
Do not touch voltage-carrying parts inside or outside the device.
