Under what conditions: Only the packaging for this product will burn.
Extinguishing Media: This product will not burn; however, welding arcs and sparks can ignite combustible and flammable materials.
Use the extinguishing media recommended for the burning materials and fire situation. See ANSI Z49.1 鈥淪afety in Welding and
Cutting鈥? and 鈥淪afe Practices鈥? Code: SP, published by the American Welding Society, P. O. Box 351040, Miami, FL 33135, and
NFPA 51B 鈥淪tandard for Fire Prevention During Welding, Cutting, and Other Hot Work,鈥? published by the National Fire Protection
Association, Batterymarch Park, Quincy, MA 02269 for additional fire prevention and protection information.
Special Fire Fighting Procedures: Full protective equipment required. When involved in a fire, these products may emit toxic and
irritating fumes of the metals, metal oxides and their compounds.
V. Reactivity Data
Stability: Stable (X) Unstable ( ) Polymerization will not occur.
Incompatible products: None currently known.
Hazardous decomposition products: Welding fumes and gases cannot be classified simply. The composition and quantity of both
are dependent upon the material being worked, the process, procedures, and consumables 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 material
being worked (such as paint, plating or galvanizing), the number of welding operations and the volume of the work area, the quality
and amount of ventilation, the position of the worker鈥檚 head with respect to the fume plume, as well as the presence of contaminants
in the atmosphere (such as chlorinated hydrocarbon vapors from cleaning or painting activities). Vapors of chlorinated hydrocarbon
solvents will decompose in the presence of heat and ultraviolet radiation and form highly toxic phosgene gas. When the materials are
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
ingredients, plus those from the material being worked and the coatings etc. noted above.
Reasonably expected decomposition products from normal use of these products include a complex of the oxides and fluorides of
the materials listed in Section II, as well as carbon monoxide, carbon dioxide, ozone and nitrogen oxides (refer to 鈥淐haracterization of
Arc Welding Fume鈥? available from the American Welding Society). FUMES FROM CORESHIELD 8Ni1, CORESHIELD 11,
CORESHIELD 11-Ni3 AND CORESHIELD 15 WILL REACH THE LIMIT FOR SOLUBLE BARIUM COMPOUNDS (0.5 mg/m3)
BEFORE THE GENERAL LIMIT FOR WELDING FUMES OF 5 mg/m3 IS REACHED. THE TLV FOR MANGANESE (0.2 mg/m3 ),
CHROMIUM AND NICKEL WILL BE REACHED BEFORE THE GENERAL LIMIT FOR WELDING FUMES OF 5 mg/m3 IS
REACHED. MONITOR FUMES FOR BARIUM, NICKEL, CHROMIUM AND MANGANESE LEVELS. A SIGNIFICANT AMOUNT OF
THE CHROMIUM IN THE FUMES CAN BE HEXAVALENT CHROMIUM, WHICH HAS A VERY LOW EXPOSURE LIMIT, 0.005
mg/m3 (5碌g/m3 ). The only way to determine the true identity of the decomposition products is by sampling and analysis. The
composition and quantity of the fumes and gases to which a worker may be overexposed can be determined from a sample obtained
from inside the welder鈥檚 helmet, if worn, or in the workers breathing zone. See ANSI/AWS F1.5, 鈥淢ethods for Sampling and
Analyzing Gases from Welding and Allied Processes,鈥? and ANSI/AWS F1.1 鈥淢ethod for Sampling Airborne Particles Generated by

VI. Physical and Health Hazard Data
WARNING: Electric arc working may create one or more of the following health or physical hazards. Fumes and gases can be
dangerous to your health. Fumes and gases containing fluoride burn eyes and skin on contact and can be fatal if swallowed. Electric
shock can kill you. Arc rays can injure eyes and burn skin. Heat rays (infrared radiation) from flame or hot metal can injure eyes.
Noise can damage hearing. See ANSI Z49.1 鈥淪afety in Welding, Cutting, and Allied Processes鈥? available from the American Welding
Society. An additional detailed description of the Health and Physical Hazards and their consequences may be found in ESAB鈥檚 free
publications F52-529 鈥淧recautions and Safe Practices for Electric Welding and Cutting鈥? and 17982 鈥淧recautions and Safe Practices
for Gas Welding, Cutting and Heating.鈥? You may obtain copies from your local supplier or by writing to the address in Section I.
Potential Health Effects: Direct contact with the product causes irritation of the eyes; irritation of the skin is not expected. If the
product is pulverized the airborne dust may irritate the mucous membranes and upper respiratory tract. The dust may also contain
crystalline silica which must be considered a possible carcinogen under OSHA 29CFR1910.1200. Exposure level must be kept below
those levels specified in Section II.
Route of overexposure: The primary route of entry of the decomposition products is by inhalation. Skin contact, eye contact, and
ingestion are possible. Absorption by skin contact is unlikely. When these products are used as recommended by THE ESAB
GROUP, and ventilation maintains exposure to the decomposition products below the limits recommended in this section,
overexposure is unlikely.
Effects of acute (short-term) overexposure to the gases, fumes, and dusts may include irritation of the eyes, lungs, nose and
throat. Some toxic gases associated with welding may cause pulmonary edema, asphyxiation, and death. Acute overexposure may
include signs and symptoms such as watery eyes, nose and throat irritation, headache, dizziness, difficulty in breathing, frequent
coughing, or chest pain. The presence of nickel compounds in fume can cause metallic taste, nausea, tightness of chest, fever, and
allergic reaction. The presence of chromium/chromate in fume can cause irritation of nasal membranes and skin. Exposure to the
fluoride ion may cause hypocalcemia鈥揷alcium deficiency in the blood that can result in muscle cramps and inflammation and necrosis
of mucous membranes. Ingestion of barium oxide can result in severe pain, vomiting, paralysis, and death.
Pre-existing Medical Conditions Aggravated by Overexposure: Individuals with allergies or impaired respiratory function may
have symptoms worsened by exposure to welding fumes; however, such reaction cannot be predicted due to the variation in
composition and quantity of the decomposition products.
Effects of chronic (long-term) overexposure to air contaminants may lead to their accumulation in the lungs, a condition which
may be seen as dense areas on chest X-rays. The severity of the change is proportional to the length of the exposure. The changes
seen are not necessarily associated with symptoms or signs of reduced lung function or disease. In addition, the changes on X-rays
may be caused by non-work factors such as smoking, etc. Long term exposure to welding and allied processes gases, dusts and
fumes may contribute to pulmonary irritation or pneumoconiosis. Inhalation of too much iron oxide fume over a long time can cause
siderosis, sometimes called 鈥渋ron pigmentation鈥? of the lung, which can be seen on a chest x-ray but causes little or no disability
Overexposure to manganese compounds may affect the central nervous system, symptoms of which are languor, sleepiness,
muscular weakness, emotional disturbances, and spastic gait. The effect of manganese on the nervous system is irreversible.
Overexposure to respirable crystalline silica may result in silicosis, a disabling lung disease; overexposure to respirable crystalline
silica is a known cause of carcinogenicity in humans. Chronic fluoride absorption can result in osseous fluorosis, increased
radiographic density of the bones and mottling of the teeth. Nickel and chromium are considered carcinogenic. Long term
overexposure to nickel fumes may also cause pulmonary fibrosis and edema. Chromates may cause an ulceration and perforation of
the nasal septum. Liver damage and allergic skin rash have also been reported. Welding fumes (not otherwise specified) are
possibly carcinogenic to humans.
Exposure limits for the ingredients are listed in Section II. The 1989 OSHA TWA for welding fume is 5 mg/m鲁. TLV-TWAs should
be used as a guide in the control of health hazards and not as fine lines between safe and excessive concentrations. As noted in
Section V, the welding fume is a mixture of many components. Therefore a statutory computation of the equivalent exposure is
required. The equivalent exposure value for the welding fume mixture shall always be less than one. When these products are used
as recommended by THE ESAB GROUP, and the preventive measures taught in this MSDS are followed, overexposure to
hazardous substances will not occur.
Emergency First Aid Measures: In case of emergency, call for medical aid. Employ first aid technique recommended by the Red
Cross. IF BREATHING IS DIFFICULT, give oxygen and call for a physician. FOR ELECTRIC SHOCK, disconnect and turn off the
power. If not breathing, begin artificial respiration, preferably mouth-to-mouth. If no detectable pulse, begin Cardio Pulmonary
Resuscitation (CPR). Immediately call a physician. FOR ARC BURN, apply cold, clean compresses and call a physician.
Eye Contact: Flush with water for at least fifteen minutes to remove all residue. If irritation persists, obtain medical
assistance.
Skin Contact: Promptly flush with soap and water to remove all residue. If irritation persists, consult a physician.
Inhalation: Remove to fresh air. If breathing has stopped, perform artificial respiration and obtain medical assistance
immediately!
Ingestion: Call a physician or your Poison Control Center IMMEDIATELY! Advise of Section II.

VII. Precautions for Safe Handling and
Use/Applicable Control Measures
Read and understand the manufacturer鈥檚 instructions and the precautionary label on this product. See American National Standard
Z-49.1, 鈥淪afety in Welding and Cutting,鈥? published by the American Welding Society, P. O. Box 351040, Miami, FL 33135 and OSHA
Publication 2206 (29 C.F.R. 1910), U.S. Government Printing Office, Superintendent of Documents, P.O. Box 371954, Pittsburgh, PA

Product Identity: DUAL SHIELD T-5 & CORESHIELD FLUX CORED WELDING ELECTRODES
FORM NO. MSDS 7972-N
DATE REVISED: 06/16/2006
Ventilation: Use enough ventilation, local exhaust at the arc, or both, to keep the exposure within legal limits. In the worker鈥檚
breathing zone and the general area, fumes and gases must be kept below the TLVs and the equivalent exposure must
compute to less than one. 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 where
local exhaust or ventilation does not keep exposure below TLVs. Where respiratory protection is necessary, NIOSH approved
respiratory protection should be used. The selection of the appropriate respiratory protection (dust respirator, etc.) should be
based on the actual or potential airborne contaminants and their concentrations present. However, at least a NIOSH approved
type TC-21-C dust mask is recommended.
Eye Protection: Wear helmet or use face shield with filter lens. As a rule of thumb, start with a shade which is too dark to see
the weld zone. Then go to the next lighter shade which gives sufficient view of the weld zone. Provide protective screens and
flash goggles, if necessary, to shield others. Wear safety glasses or goggles when handling this material to prevent eye
contact. Do not wear contact lenses in any environment where dust or fumes are present. Readily available eye baths are
recommended in areas where operations may produce fumes and dusts.
Protective Clothing: Wear head, hand, and body protection which help to prevent injury from radiation, sparks and electrical
shock. See ANSI Z-49.1. At a minimum, this includes welder鈥檚 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 touch live electrical
parts and to insulate himself from work and ground.
Hygienic Work Practices: Avoid contact to eyes, skin, and mucous membranes. Avoid inhalation of vapors. Wash thoroughly
after handling and use. Do not smoke, eat, drink, chew gum or tobacco, or apply cosmetics within the working area. Do not
carry or store tobacco products, gum, food, drinks or cosmetics in the working area. Otherwise follow the standards of good
industrial hygiene practices.
Procedure for Cleanup of Spills or Leaks: NOT APPLICABLE
Waste Disposal Method: Prevent waste from contaminating surrounding environment. Discard any product, residue,
disposable container, or liner in an environmentally acceptable manner, in full compliance with Federal, State and Local
regulations.
