grams per cubic meter and the TLV for insoluble chromium (VI) is
0.01 milligrams per cubic meter.
(c)
Values are for manganese fume. STEL(Short Term Exposure Limit) is
3.0 milligrams per cubic meter. Valucs are those proposed by OSHA in

SECTION III- HAZARD DATA
Non Flammable; Welding
arc and sparks can ignite combustibles and flammable products. See
Z49.1 referenced in Section VI.
Product is inert, no
special handling or spill procedures required. Not regulated by DOT.
(CONTINUED ON SIDE TWO)
SECTION IV-HEALTH HAZARD
DATA
Threshold Limit
Value: The
ACGIH recommended general limit for Welding Fume NOC-(Not Otherwise
Classified) is 5 mg/m3.
ACGIG-1999 preface states
that the TLV-TWA should be used as guides in the control of health
hazards and should not be used as fine lines between safe and
dangerous concentrations. See Section V for specific fume
constituents which may modify this TLV. Threshold Limit Values are
figures published by the American Conference of Government
Industrial Hygienists. Units are milligrams per cubic meter of air.
Effects of Overexposure:
Electric arc
welding may create one or more of the following health hazards:
Fumes and Gases can be dangerous to your health.
Common entry is by inhalation. Other possible routes are skin
contact and ingestion.
Short-term (acute)
overexposure to welding fumes may result in discomfort such as metal
fume fever, dizziness, nausea, or dryness or irritation of nose,
throat, or eyes. May aggravate pre-existing respiratory problems
(e.g. asthma, emphysema). Chromates present in the fume have been
known to cause severe irritation of the bronchial tubes and lungs.
Asthma has been reported. Exposure to extreme cases it can cause
loss of consciousness and death.
Long-term (chronic)
overexposure
to welding fumes can lead to siderosis (iron deposits in lung) and
may affect pulmonary function. Manganese overexposure can affect the
central nervous system, resulting in impaired speech and movement.
Bronchitis and some lung fibrosis have been reported. Chromates may
cause ulceration and perforation of the nasal septum. Liver damage
and allergic reactions, including skin rash, have been reported.
Repeated exposure to fluorides may cause excessive calcification of
the bone and calcification of ligaments of the ribs, pelvis and
spinal column. May cause skin rash. Chromium and nickel and their
compounds are on the IARC (International Agency for Research on
Cancer) and NTP (National Toxicology Program) Lists as posing a
carcinogenic risk to humans. WARNING: This product contains or
produces a chemical known to the State of California to cause cancer
and birth defects (or other reproductive harm). (California Health &
Safety Code Section 25249.5 et seq).
Arc Rays can injure eyes
and burn skin. Skin cancer has been reported.
Electric Shock can kill. If welding must be
performed in damp locations or with wet clothing, on metal
structures or when in cramped positions such as sitting, kneeling or
lying, or if there is a high risk of unavoidable or accidental
contact with workpiece, use the following equipment: Semiautomatic
DC Welder, DC Manual (Stick) Welder., or AC Welder with Reduced
Voltage Control.
Emergency and First
Aid Procedures: Call for medical aid. Employ first and
techniques recommended by the American Red Cross.
IF BREATHING IS
DIFFICULT give oxygen. IF NOT BREATHING employ CPR (Cardiopulmonary
Resuscitation) techniques.
IN CASE OF ELECTRICAL
SHOCK, turn off power and follow recommended treatment. In all a
physician.
SECTION V-REACTIVITY
DATA
Hazardous
Decomposition Products:
Welding fumes and gases
cannot be classified simply. The composition and quantity of both
are dependent upon the metal welded, the process, procedure and
electrodes used.
Other conditions which
also influence the composition and quantity of the fumes and gases
to which workers may be exposed include: coatings on the metal being
welded (such as paint, plating., or galvanizing), the number of
welders and the volume of the worker area, the quality and amount of
ventilation, the position of the welder's head with respect to the
fume plume, as well as the presence of contaminants in the
atmosphere (such as chlorinated hydrocarbon vapors from cleaning and
degreasing activities.)
When the electrode is
consumed, the fume and gas decomposition products generated are
different in percent and form from the ingredients listed in Section
II. Decomposition products of normal operation include those
originating from the volatilization, reaction, or oxidation of the
materials shown in Section II, plus those from the base metal and
coating, etc., as noted above.
Reasonably expected fume
constituents of this product would include: Primarily iron oxide and
fluorides; secondarily complex oxides of aluminum, calcium,
chromium, magnesium, manganese, nickel, potassium, silicon, sodium
and zirconium when used with recommended Lincolnweld fluxes.
Primarily iron oxide, manganese oxide, and complex chromium oxides;
secondarily complex oxides of molybdenum (316 types) and nickel when
used with gas shielding.
Maximum fume exposure
guideline for this product (based on Cr(VI) content) is 0.8
milligrams per cubic meter for submerged arc and 3.0 milligrams per
cubic meter (based on Cr(III) content) when used with gas shielding
for GMAW and 1.5 milligrams per cubic meter (based) on manganese
content) when used for CTAW. See MSDS for flux being used.
The OSHA PEL
(Permissible Exposure Limit) is a ceiling value that shall not be
exceeded at any time.
Keep exposure as
low as possible.
Indoors, use local exhaust; outdoors, a respirator may be required.
Gaseous reaction
products may include carbon monoxide and carbon dioxide. Ozone and
nitrogen oxides may be formed by the radiation from the arc.
Determine the
composition and quantity of fumes and gases to which workers are
exposed by taking an air sample from inside the welder's helmet if
worn or in the worker's breathing zone. Improve ventilation if
exposures are not below limits. See ANSI/AWS F1.1,F1.2,F1.3,F1.4 and
F1.5, available from the American Welding Society, 550 N.W. LeJeune
Road, Miami, FL 33126.
SECTION VI AND VII
CONTROL MEASURES
AND PRECAUTIONS FOR SAFE HANDLING AND USE
Read and understand
the manufacturer's instruction and the precautionary label on
the product, Request Lincoln Safety Publication E205. See
American National Standard Z49.1, 'Safety In Welding, Cutting
and Allied Processes' published by the American Welding Society,
550 N.W. LeJeune Road, Miami, FL, 33126 and OSHA Publication
2206 (29CFR1910), U.s. Government Printing Office,
Superintendent of Documents, P.O.Box 371954, Pittsburgh, PA
15250-7954 for more details on many of the following:
Ventilation:
Use enough ventilation, local exhaust at the arc, or both to
keep the fumes and gases from the worker's breathing zone and
the general area. Train the welder to keep his head out of the
fumes. Keep exposure as low as possible.
Respiratory
Protection:
Use respirable fume
respirator or air supplied respirator when welding in confined
space or general work area when local exhaust or ventilation
does not keep exposure below TLV.
Eye Protection:
Wear helmet or use face shield with filter lens shade number 12*
or darker. Shield others by providing screens and flash goggles.
(*) No specific recommendation for submerged arc.
Protective
Clothing:
Wear hand, head, and body protection which help to prevent
injury from radiation, sparks and electrical shock. See Z49.1.
At a minimum this includes welder's gloves and a protective face
shield, and may include arm protectors, aprons, hats, shoulder
protection, as well as dark substantial clothing, Train the
welder not to permit electrically live parts or electrodes to
contact skin… or clothing or gloves if they are wet. Insulate
from work and ground.
Disposal
Information:
Discard and product, residue, disposable container, or liner as
ordinary waste in and environmentally acceptable manner
according to Federal, State and Local Regulations unless
otherwise noted.
