Danger from toxic
gases and va-
pours
- protect eyes and face from UV rays, heat and sparks using a protective
visor and regulation filter.
- wear regulation protective goggles with side protection behind the safety
visor.
- wear stout footwear that provides insulation even in wet conditions.
- protect the hands with suitable gloves (electrically insulated and providing
protection against heat).
- wear ear protection to reduce the harmful effects of noise and to prevent
injury.
Keep all persons, especially children, out of the working area while any devic-
es are in operation or welding is in progress. If, however, there are people in
the vicinity,
- make them aware of all the dangers (risk of dazzling by the arc, injury
from flying sparks, harmful welding fumes, noise, possible danger from
mains or welding current, etc.),
- provide suitable protective equipment or
- erect suitable safety screens/curtains.
The fumes produced during welding contain harmful gases and vapours.
Welding fumes contain substances that may, under certain circumstances,
cause birth defects or cancer.
Keep your face away from welding fumes and gases.
Fumes and hazardous gases,
- must not be breathed in
- must be extracted from the working area using appropriate methods.
Ensure an adequate supply of fresh air.
If this cannot be provided, a protective mask with an air supply must be worn.
If there is any doubt about whether the extraction system is powerful enough,
then the measured toxic emission values should be compared with the permis-
sible limit values.
The following components are responsible, amongst other things, for the de-
gree of toxicity of welding fumes:
- Metals used for the workpiece
- Electrodes
- Coatings
- Cleaners, degreasers, etc.
The relevant material safety data sheets and manufacturer's specifications for
the listed components should therefore be studied carefully.
Flammable vapours (e.g. solvent fumes) should be kept away from the arc's
radiation area.
