SECTION IV - HEALTH HAZARD DATA
Threshold Limit Value: The ACGIH recommended general limit for Welding Fume NOS - (Not Otherwise Specified) is 5 mg/m3.
ACGIH-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 extremely high levels of fluorides can
cause abdominal pain, diarrhea, muscular weakness, and convulsions. In 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. 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. Chromates may cause ulceration and perforation of the nasal septum. Liver damage and allergic reactions,
including skin rash, have been reported. Chromates contain the hexavalent form of chromium. Hexavalent chromium and its compounds are on
the IARC (International Agency for Research on Cancer) and NTP (National Toxicology Program) lists as posing a cancer risk to humans. Nickel
and its compounds are on the IARC (International Agency for Research on Cancer) and NTP (National Toxicology Program) lists as posing a
cancer risk to humans. Nickel compounds are skin sensitizers with symptoms usually occurring after repeated exposure - ranging from a slight
itch to severe dermatitis. 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 aid 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 cases call 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 being 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 nickel oxide, potassium oxide and fluorides; secondarily
complex oxides of aluminum, chromium, iron, manganese, molybdenum, niobium, silicon, sodium and titanium.
Maximum fume exposure guideline for this product (based on Cr (VI) content) is 0.2 milligrams per cubic meter.
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 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 (both available for free download at http://www.lincolnelectric.com/community/safety/) 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.
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 any product, residue, disposable container, or liner as ordinary waste in an environmentally acceptable manner according to
Federal, State and Local Regulations unless otherwise noted. No applicable ecological information available.
