HAZARDS IDENTIFICATIONS

EYE:

If irritation occurs due to welding fumes or from dust when grinding tungsten, flush with water. If irritation persists
seek medical attention.
Adverse reaction from contact with these electrodes is not likely. Prompt medical attention should be obtained forburns or irritation resulting from welding process.
Consult physician.
Move the exposed individual from the welding area to fresh air. Aid breathing and seek medical attention ifnecessary.

FIRST AID MEASURESINHALATION:

SKIN CONTACT:

Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen and get medicalattention.
Do NOT induce vomiting. Get immediate medical attention.
Immediately flush eyes with water and continue washing for at least 15 minutes. Obtain medical attention if discomfort
persists.
Flush with water for at least 15 minutes. Seek medical attention if irritation develops or persists.

ACCIDENTAL RELEASE MEASURESLEAK / SPILLRESPONSE:Avoid release into the environment. Avoid dispersal of spilled material and contact with soil, ground and surface waterdrains and sewers. Take up mechanically. Collect the material in labeled containers and dispose of according to local andregional authority requirements.
Wear appropriate personal protective equipment as specified in Section 8. Ensure adequate ventilation.

SPECIALINSTRUCTIONS:SECTION 7.

HANDLING AND STORAGE

HANDLING
PROCEDURES /EQUIPMENT:STORAGEREQUIREMENTS:

Welding may produce dust, fumes and gases hazardous to health. Avoid breathing dust, fumes and gases. Use adequate
ventilation. Keep away from sources of ignition. Avoid contact with skin, eyes and clothing. Do not eat, drink and smoke inwork areas. End the end of the work shift, hands, other exposed skin should be washed thoroughly. Follow goodhousekeeping practices to ensure that powders and dusts from grinding operations do not accumulate; such residue canbe highly flammable and may pose special health hazards from thorium containing electrodes. Tungsten-Thorium Oxide
alloys are generally safe to handle during use under all normal conditions and environments. However, special
precautions must be taken during the grinding or machining of tips of electrodes that contain Thorium Oxide to avoid thegeneration and subsequent inhalation and ingestion of dusts from these operations. Any dusts generated during these
operations may be considered “Source Material” as defined by the Nuclear Regulatory Commission and therefore be
subject to the requirements of 10 CFR, Parts 20 and 40. Routine wet mopping or vacuuming with an explosion proof
vacuum fitted with a HEPA filter, may be considered to reduce accumulation of dusts.
Store in cool, dry and well-ventilated place. Keep away from incompatible materials. Keep away from heat and openflame.

SECTION 8.

EXPOSURE CONTROLS, PERSONAL PROTECTION

EYE PROTECTION:

Wear helmet or face shield with filter lens of appropriate shade number. See ANSI/ASC Z49.1 Section 4.2. Provide
protective screens and flash goggles, if necessary, to shield others.
Wear head and body protection, which help to prevent injury from radiation, sparks, flame and electrical shock. See ANSI
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 employee not to touch live electrical parts and toinsulate him/herself from work and ground. Welders should not wear short sleeve shirts or short pants.

No information on degradability, soil mobility, and/or bioaccumulative potential.

SECTION 13.

DISPOSAL CONSIDERATIONSNo additional information available.
Welding fumes and gases cannot be classified simply. The composition and quantity of both are dependent upon themetal being welded, the process, procedure and welding consumables used. Other conditions which also influence thecomposition and quantity of the fumes and gases to which workers may be exposed include: coating on the metal beingwelded (i.e. paint, painting, galvanizing), the number of welders, the volume of the work area, the quality and the amountof ventilation, the position of the welders head with respect to the fume plume, as well as the presence of contaminants inthe atmosphere (such as chlorinated hydrocarbon vapors from the cleaning and degreasing activities). When an electrodeis consumed, the fume and gas decomposition products generated are different in percent and form from the ingredients
listed in Section 3. Fume and gas decomposition, and not the ingredients in the electrode, are important. The
concentration of a given fume or gas component may decrease or increase by many times the original concentration.
Also, new compounds not in the electrodes may form. Decomposition products of normal operation include thoseoriginating from the volatilization, reaction or oxidation of the materials shown in Section 3, plus those from the base metal
coating, etc., as noted above. Reasonable expected fume constituents of this product would include: Complex oxides ofiron, manganese, silicon, chromium, nickel, columbium, molybdenum, copper, carbon dioxide, carbon monoxide, ozone
and nitrogen Oxides. Some products will also contain antimony, barium, molybdenum, aluminum, columbium,magnesium, strontium, tungsten, and or zirconium. Fume limit for chromium, nickel and or manganese may be reached
before limit of 5 mg/m3 of general welding fumes is reached. 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 compositionand 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 Fl.!, Fl.3 andFl.5, available from the American Welding Society, 550 N.W. Lejeune Road, Miami, FL 3312
