Personal Protec-
tive Equipment
Danger from Tox-
ic Gases and Va-
pors
Please take the following precautions for your own personal safety:
Persons present in the sealed cell for the LaserHybrid process must
wear rigid, wet-insulating footwear
protect hands with appropriate gloves (featuring electrical insulation and ther-
mal 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 in-
sert 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)
If there are persons present in the sealed cell for the LaserHybrid process,
-
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 oxygen in the breathable air, hazards posed by laser light,
etc.)
-
provide protective equipment
-
construct protective walls or install protective curtains.
The fumes produced during welding contain toxic gases and vapors.
Welding fumes contain substances that may cause birth defects and cancer in
some circumstances.
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 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, com-
pare the measured toxic emission values against the permissible limit values.
