The increased risk of an elec-
„
tric shock as the welder comes
into contact with the earth
if he/she is using a Class I
welding power source, the
housing of which is earthed
through its conductor.
z Protective clothing
At work, the welder must
„
protect his/her whole body by
using appropriate clothing and
face protection against radia-
tions and burns. The following
steps must be observed:
Wear protective clothing
ƒ
prior to welding work
Wear gloves.
ƒ
Open windows or use fans
ƒ
to guarantee air supply.
Wear safety goggles and
ƒ
face mask.
Gauntlet gloves made of a
„
suitable material (leather) must
be worn on both hands. They
must be in perfect condition.
A suitable apron must be
„
worn to protect clothing from
flying sparks and burns. When
specific work, e.g. overhead
welding, is required, a protec-
tive suit must be worn and,
if necessary, even head
protection.
Protection against rays
and burns
Warn of the danger to the
„
eyes by hanging up a sign
saying "Caution! Do not look
into flames!". The workplaces
must be shielded so that the
persons in the vicinity are
protected. Unauthorised
persons must be kept away
from welding work.
The walls in the immediate
„
vicinity of fixed workplaces
should neither be bright
coloured or shiny. Windows
up to head height must be
protected to prevent rays
from penetrating or reflecting
through them, e.g. by using
suitable paint.
