suitable clothing and a face guard.
2.
Slip-on gloves made of a suitable material
(leather) must be worn on both hands. They
must be in perfect condition.
3.
Suitable aprons must be worn to protect clothing
from sparks and burns. A safety suit and, if
necessary, head protection must be worn if
required by the type of work in question, e.g.
overhead welding.
Protection from radiation and burns
1.
Provide information about the risk to eyes at the
working site in the form of a poster with the
wording “Caution – do not look at the flames”.
Workplaces are to be screened off wherever
possible so that personnel in the vicinity are
protected. Unauthorized persons are to be kept
away from the welding work.
2.
The walls in the immediate vicinity of stationary
workplaces should not have a light color or a
sheen. Windows up to head height are to be
protected against radiation passing through them
or reflecting off them, for example by coating
them with a suitable paint.
