connecting the pressure gauge. The protection
gases must be dispensed at the pressures re-
commended for the different welding/cutting
procedures.
Periodically inspect the ducts and rubber tubes
to make sure they are properly sealed. Never
use a source of flame/fire to detect gas leaks;
use a suitable detector or brush the suspected
area with soapy water.
Warning: Improper use of the gas,
in particular in small spaces (cargo
holds, tanks, reservoirs, silos etc), will
expose the user to the following risks:
1 – Suffocation or intoxication with gas and
gassy mixtures containing less than 20% of
carbon dioxide (these gases replace oxygen in
the air);
2 – Fire and explosion with gassy mixtures
containing hydrogen (hydrogen is light and
flammable; it accumulates beneath ceilings or
in nooks, resulting in risk of fire and explosion).

NOISE

The safety prescriptions regarding workers'
protection against the risks derived from expo-
sure to noise are treated by European Directive
2003/10/CE of 6 February 2003, which descri-
bes the need to adopt measures to promote sa-
fety, hygiene and good health in the workplace.
The noise emitted by the welding and cutting
generators depends on the intensity of the
welding/cutting current, on the procedure used
(MIG, pulsed MIG, TIG etc), on the work envi-
ronment (size of the area, reverberation of the
walls etc).
Under normal work conditions, the noise emit-
ted by a welding/cutting generator does not
exceed 80 dBA; should it be necessary to emit
noise above 85 dBA, the worker involved must
be equipped with suitable protections, such as
helmet and ear plugs, and be informed by sui-
table signaling.

FIRST AID

Each country specifies the minimum personal
protection equipment that employers must pro-
vide their first aid team with, for immediate help
in the event of electric shock, suffocation, burns
of different types, eye burns etc.
Beware of electric shock and electric
burns: the workplace may be dange-
rous; do not attempt to help the patient
if the power source is still active. Cut
off the appliance from the power source and
remove all power cables from the victim using
a piece of dry wood or any other insulating ma-
terial.
