Danger from Tox-
The fumes produced during welding contain toxic gases and vapors.
ic Gases and Va-
Welding fumes contain substances that may cause birth defects and cancer in some cir-
pors
cumstances.
Keep your head out of the welding fumes and gases.
Take the following precautionary measures for fumes and harmful gases:
-
-
Ensure that there is sufficient fresh air.
Use breathing apparatus with air supply if there is insufficient ventilation.
When no welding is taking place, close the valve of the shielding gas cylinder or the main
gas supply.
If there is uncertainty as to whether the extraction capacity is sufficient, compare the mea-
sured toxic emission values against the permissible limit values.
The following components are factors that determine how toxic the welding fumes are:
-
-
-
-
Consult the corresponding material safety data sheets and manufacturer's instructions for
the components listed above.
Keep flammable vapors (such as solvent vapors) out of the laser and arc radiation range.
Danger Posed by
Risk of asphyxiation due to uncontrolled shielding gas leak
Shielding Gas
Leak
wear rigid, wet-insulating footwear
protect hands with appropriate gloves (featuring electrical insulation and thermal pro-
tection)
protect their eyes from laser beams by wearing regulation-compliant safety glasses for
lasers. To protect their face and eyes against UV beams, further protection in the form
of a protective shield with regulation-compliant filter insert for laser protection class 4
must also be used in front of the safety glasses for lasers and the person's face. Do
not look into the laser beam, even with a regulation-compliant filter insert for laser pro-
tection class 4.
Only wear suitable (flame-resistant) clothing
Wear hearing protection designed for crossjet noise (120 dbA)
inform them of all the dangers that may be posed during operation (e.g. potential ac-
cumulation of gases hazardous to health, risk of asphyxiation due to lack of oxygen in
the breathable air, hazards posed by laser light, etc.)
provide protective equipment
construct protective walls or install protective curtains.
Do not breathe them in.
Extract them from the work area using appropriate equipment.
