Any symptom of discomfort or pain in the
eyes, nose or throat may be caused by ina-
dequate ventilation; if this is the case, imme-
diately interrupt work and ventilate the area.
Do not weld metals or painted metals contai-
ning zinc, lead, cadmium or beryllium, unless
the operator and the persons nearby are
using breathing apparatuses or wearing hel-
mets with oxygen cylinder.
The employer is required to evaluate the risks
to which workers are exposed during the use
of welding machines, focusing in particu-
lar on the risks deriving from the welding of
stainless steel alloys.
In relation to the legislation in force in the
country where the welding machines are sold,
the employer who uses the welding machines
to weld stainless steel alloys is required to eva-
luate the carcinogenic risk deriving from the de-
velopment of welding fumes containing nickel
and hexavalent chromium in gaseous form (re-
member that nickel and hexavalent chromium
in the gaseous state are carcinogenic).
Should welding operations be carried out in
conditions different from the usual working
conditions, with an increased risk of electric
shock (reduced or damp working area), ad-
ditional precautions must be taken, such as:
- Using power generators marked "S";
- Placing the power generator out of the wor-
king area;
- Reinforcing personal protection devices,
ground insulation and insulation between the
piece to be welded and the operator (Fig. 7).

Workers and their assistances must never
allow any parts of their bodies to come into
contact with metallic materials at high tempe-
ratures or which are moving (Fig. 8).
Using the arc welding and cutting equipment
requires strict respect for safety conditions
regarding electric currents. Make sure that
no metallic parts accessible to the operators
may come into direct or indirect contact with
a phase conductor or with the neutral of the
power grid.
All electrode holder and torches used must
be in good conditions. Do not coil the welding
cables around your body and never point the
torch to other people (Fig. 9).
Make sure that no power cables from other ap-
pliances, control lines or phone cables are near
the welding generators.
Any other electric equipment in the welding
area must be in conformity with the correspon-
ding EMC regulation.
