Suitable protective clothing must be worn when working with the device. The protective
clothing must have the following properties:
-
Flame-resistant
-
Insulating and dry
-
Covers the whole body, is undamaged and in good condition
-
Safety helmet
-
Trousers with no turn-ups
Protective clothing refers to a variety of different items. Operators should:
-
Protect eyes and face from UV rays, heat and sparks using a protective visor and reg
-
ulation filter
-
Wear regulation protective goggles with side protection behind the protective 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 devices are in op
-
eration 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 risks from mains current and welding
current, etc.)
-
Provide suitable protective equipment
-
Alternatively, erect suitable safety screens/curtains.
Danger from toxic
gases and va
-
pours
The fumes produced during welding contain harmful gases and vapours.
Welding fumes contain substances that cause cancer, as stated in Monograph 118 of the
International Agency for Research on Cancer.
Use at-source extraction and a room extraction system.
If necessary, use a welding torch with an integrated extraction device.
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. Ensure that there is a ventilation rate of at least
20 m³ per hour at all times.
Otherwise, a welding helmet with an air supply must be worn.
If there is any doubt about whether the extraction capacity is sufficient, the measured toxic
emission values should be compared with the permissible limit values.
The following components are responsible, amongst other things, for the degree of toxicity
of welding fumes:
-
Metals used for the workpiece
-
Electrodes
-
Coatings
-
Cleaners, degreasers, etc.
-
Welding process used
The relevant material safety data sheets and manufacturer's specifications for the listed
components should therefore be studied carefully.
Recommendations for trade fair scenarios, risk management measures and for identifying
working conditions can be found on the European Welding Association website under
Health & Safety (https://european-welding.org).
