Danger from
The fumes produced during welding contain toxic gases and vapors.
Toxic Gases and
Welding fumes contain substances that may cause birth defects and cancer in some cir-
Vapors
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
measured 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
Shielding gas is colorless and odorless and may suppress the oxygen in the ambient air
Leak
in the event of leakage.
8
wear rigid, wet-insulating footwear
protect hands with appropriate gloves (featuring electrical insulation and thermal
protection)
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 protection 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
accumulation of gases hazardous to health, risk of asphyxiation due to lack of oxy-
gen 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.
