NOT APPLICABLE
SECTION IV: FIRE AND EXPLOSION HAZARD DATA
Non-Flammable: Welding arc and sparks can ignite combustibles. See Z-49.1 referenced in Section VI.
SECTION V: REACTIVITY DATA
Hazardous Decomposition Products
Welding fumes and gases cannot be classified simply. The composition and quantity of these fumes and gases are dependent
upon the metal being welded, the procedures followed and the electrodes used. Workers should be aware that the composition
and quantity of fumes and gases to which they may be exposed, are influenced by: coatings which may be present on the metal
being welded (such as paint, plating, or galvanizing), the number of welders in operation and the volume of the work 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 procedure). When the
electrode is consumed, the fumes and gas decomposition products generated are different in percent and form from the
ingredients listed in Section II, The composition of these fumes and gases are the concerning matter and not the composition of
the electrode itself. Decomposition products include those originating from the volatilization, reaction, or oxidation of the
ingredients shown in Section II, plus those from the base metal, coating and the other factors noted above.
Reasonable expected fume constituents of this product would include: Complex oxides of aluminum, iron, manganese, silicon,
3
titanium, chromium, magnesium, zinc, beryllium and copper. Fume limit for Cr (VI) (0.05 mg/m ) may be reached before limit of
3
5 mg/m for general welding fumes is reached. Watch the (Cr VI) level. Other complex oxides may be present when using fluxes.

*Ceiling Limit **Short Term Exposure Limit Gaseous reaction products may include carbon monoxide and carbon dioxide Ozone and nitrogen
oxides may be formed by the radiation from the arc. One method of determining the composition and quantity of the fumes and gases to which
the workers are exposed is to take an air sample from inside the welder's helmet while worn or within the worker's breathing zone. See
ANSI/AWS F1.1 publication available from the American Welding Society 550 N.W. LeJeune Road, Miami, Florida 33126.
SECTION VI: HEALTH HAZARD DATA
3
Threshold Limit Value: The ACGIH recommended general limit for welding fume NOC (Not otherwise classified) is 5 mg/m .
ACGIH-1985 preface states: "The TLC-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.
Common Entry Is by Inhalation or Through the Eyes and Skin.
Effects of Overexposure: Inhalation of welding fumes and gases can be dangerous to your health. Short-term (acute)
overexposure to welding fumes may result in discomfort such as dizziness, nausea, or dryness or irritation of nose, throat, or
eyes. Chromium (VI) compounds present in the fume may cause severe irritation of the bronchial tubes and lungs. Ingesting
Chromium (VI) salts may cause injury or death. Chromium (VI) compounds may burn eyes. Chromium compounds may cause
allergic reactions in some people. Beryllium in fume or dust form is highly toxic. Inhalation of excessive levels of beryllium and
beryllium compounds can cause pneumonitis (inflammation of the lung tissues). Long-term (chronic) over-exposure to welding
fumes can lead to siderosis (iron deposits in lung) and is believed to affect pulmonary function. Constant inhalation of chromium
(VI) compounds may cause an ulceration and perforation of the nasal septum as well as liver and kidney damage. Workers
exposed to chromium (VI) compounds and beryllium has a higher incidence of lung and nasal cancers. Long-term exposure to
beryllium by inhalation can cause berylliosis (progressive lung disease) and systemic beryllium disease. Chromium and
Beryllium compounds are on the IARC (International Agency for Research of Cancer) list as posing a carcinogenic risk to
humans. Arc Rays can injure yes and burn skin. Electric shock can kill. See Section VII.
Emergency and First Aid Procedures: Call for medical assistance. Use first aid procedures recommended by the American
Red Cross. If breathing is difficult ?give oxygen. If not breathing-use CPR (cardiopulmonary resuscitation).
Carcinogenicity OSHA (29 CFR 1910.1200) lists Nickel and Chromium as possible carcinogens.
SECTION VII: CONTROL MEASURES AND PRECAUTIONS FOR SAFE HANDLING AND
USE
Read and understand the manufacturer's instructions and precautionary label on this product. See American Standard Z49.1
Safety in Welding and Cutting, published by the AMERICAN WELDING SOCIETY, 550 N.W. Lejenune Road, Miami, Florida
33126 and OSHA Publication 2206 (29 CFR 1910), U.S.Government Printing Office, Washington D.C. 20402 for more details
on the following topics.
Ventilation: Use plenty of ventilation and/or local exhaust at the arc, to keep the fumes and gases below the threshold limit value
within the worker's breathing zone and the general work area. Welders should be advised to keep their head out of the fumes.
Respiratory Protection: Use respirable fume respirator or air supplied respirator when welding in a confined space or general
work area where local exhaust and/or ventilation does not keep exposure below the threshold limit value.
Eye Protection: Wear a helmet or face shield with a filter lens shade number 12-14 or darker. Shield other workers by providing
screens and flash goggles.
Protective Clothing: Wear approved head, hand and body protection, which help to prevent injury from radiation, sparks and
electrical shock. See ANSI Z-49.1. This would include wearing welder's gloves and a protective face shield and may include arm
protectors, apron, hats, shoulder protection, as well as dark substantial clothing. Welders should be trained not to allow
electrically live parts to contract the skin or wet clothing and gloves. The welders should insulate themselves from the work and
ground.
Waste Disposal Method: Discard any product, residue, disposal container, or liner in an environmentally acceptable manner
approved by Federal, State and Local regulations.
