Those involved with the welding
industry are obligated to provide
safe working conditions and be
aware of the potential hazards
associated with welding fumes,
gases, radiation, electrical
shock, heat, eye injuries, burns,
etc. Various local, municipal,
state, and federal regulations
(OSHA, for example) relative to
the welding and cutting processes
must be considered.
Nickel-, cobalt-, and iron-based
alloy products may contain, in
varying concentrations, the
following elemental constituents:
aluminum, cobalt, chromium,
copper, iron, manganese,
molybdenum, nickel, and
tungsten. For specific concentrations
of these and other
elements present, refer to the
Material Safety Data Sheets
(MSDS) H2071 and H1072 for
the product.
The operation and maintenance
of welding and cutting equipment
should conform to the
provisions of American National
Standard ANSI Z49.1, Safety in
Welding and Cutting. Attention
is especially called to Section 4
(Protection of Personnel),
Section 5 (Ventilation), and
Section 7 (Confined Spaces) of
that document. Adequate
ventilation is required during all
welding and cutting operations.
Specific requirements are
included in Section 5 for natural
ventilation versus mechanical
ventilation methods. When
welding in confined spaces,
ventilation shall also be sufficient
to assure adequate
oxygen for life support.
The following precautionary
warning, which is supplied with
all welding products, should be
provided to, and fully understood
by, all employees involved
with welding.
Caution
Welding may produce fumes
and gases hazardous to health.
Avoid breathing these fumes
and gases. Use adequate
ventilation. See ANSI/AWS
Z49.1, Safety in Welding and
Cutting published by the American
Welding Society.
EXPOSURES: Maintain all
exposures below the limits
shown in the Material Safety
Data Sheet, and the product
label. Use industrial hygiene air
monitoring to ensure compliance
with the recommended
exposure limits. ALWAYS USE
EXHAUST VENTILATION.
RESPIRATORY PROTECTION:
Be sure to use a fume respirator
or air supplied respirator when
welding in confined spaces or
where local exhaust or ventilation
does not keep exposure
below the PEL and TLV limits.
WARNING: Protect yourself and
others. Be sure the label is read
and understood by the welder.
FUMES and GASES can be
dangerous to your health.
Overexposure to fumes and
gases can result in LUNG
DAMAGE. ARC RAYS can
injure eyes and burn skin.
ELECTRIC SHOCK can kill. |
