SECTION IV 鈥? FIRE AND EXPLOSION HAZARD DATA
Non-Flammable: Welding arc and sparks can ignite combustibles. See Z-49.1 referenced in Section VI.
SECTION V 鈥? 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鈥? head with respect to the fume plume, as well as the presence of contaminants in the
s
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 iron, manganese, silicon, titanium, magnesium, calcium,
potassium, zinc, sodium and aluminum. Fluorides will also be present.

Gaseous reaction products may include carbon monoxide and carbon dioxide

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鈥? helmet while worn or within the worker鈥? breathing zone. See ANSI/AWS F1.1 publication available from the American Welding Society
s s
550 N.W. LeJeune Road, Miami, Florida 33126.
SECTION VI鈥? HEALTH HAZARD DATA
Threshold Limit Value: The ACGIH recommended general limit for welding fume NOC (Not otherwise classified) is 5 mg/m3. ACGIH-1985 preface
states: 鈥淭he 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.鈥? See section V for specific fume constituents, which may modify this TLV.
Common Entry Is by Inhalation.
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 abdominal pain, diarrhea, muscular weakness and convulsions. Continued inhalation could cause loss of consciousness and death. Long-term
(chronic) over-exposure to welding fumes can lead to siderosis (iron deposits in lung) and is believed to affect pulmonary function. Repetitive exposure
to fluoride fumes and/or gases may cause excessive calcification of the bones and ligaments of the ribs, pelvis and spinal column.
Arc Rays can injure eyes 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 鈥? give oxygen. If not breathing-use CPR (cardiopulmonary resuscitation).
Carcinogenicity
These products do not contain ingredients that are defined as carcinogenic per 29 CFR 1910.1200-Hazard Communication Standard.
SECTION VII 鈥? CONTROL MEASURES AND PRECAUTIONS FOR SAFE HANDLING AND USE
Read and understand the manufacturer鈥? instructions and precautionary label on this product. See American Standard Z49.1 Safety in Welding and
s
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鈥檚
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鈥? gloves and a protective face shield and may include arm protectors, apron, hats, shoulder protection,
s
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.
