SECTION IV ?FIRE AND EXPLOSION DATA
(NON-FLAMMABLE) Welding arc and sparks can ignite combustible. Refer to ANSI Z49.1 referenced in Section 7 for precaution to be taken.
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, procedures 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 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
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 2. Decomposition products of normal operation include those originated from the volatilization, reaction or oxidation of
the materials shown in Section 2, plus those from the base metal and coating, etc., as noted above. It is understood, however, that the elements and/or
oxides to be mentioned are virtually always present as complex oxides and not as metals (See Characterization of Arc Welding Fume, from the
American Welding Society). The elements or oxides listed below correspond to the ACGIH categories found in "Threshold Limit Values for
Chemical Substances and Physical Agents" published by ACGIH. Reasonably expected constituents of the fume would include: complex oxides of
iron, manganese, silicon and titanium. They may have fluorides present. They may also contain chromium, nickel, molybdenum and/or copper.

Gaseous reaction products may include carbon monoxide and carbon dioxide. Ozone and nitrogen oxides may be formed by radiation from the arc.
One recommended way to determine the composition and quantity of fumes and gases to which workers are exposed is to take an air sample inside
the welder's helmet if worn or in the worker's breathing zone. See ANSI/AWS F1.1, available from the American Welding Society, P.O. Box
351040, Miami, FL 33135. Also available from AWS is F1.3, "Evaluating Contaminants in the Welding Environment ?A Sampling Strategy
Guide",, which gives additional advice on sampling. At a minimum materials listed in this section should be analyzed.
SECTION VI ?HEALTH AND HAZARD DATA
Effects of Overexposure ?Electric are welding may create one or more of the following health hazards:
ARC RAYS can injure eyes and burn skin.
ELECTRIC SHOCK can kill. See Section 7.
FUMES AND GASES can be dangerous to your health.
PRIMARY ROUTES OF ENTRY are the respiratory system, eyes and/or skin.
Short ?Term (acute) Overexposure effects ?br>
Welding Fumes ?May result in discomfort such as dizziness, nausea or dryness or irritation of the nose, throat or eyes.
Iron, Iron Oxide ?None or known. Treat as a nuisance dust or fume.
Manganese ?Metal fume fever characterized by chills, fever, upset stomach, vomiting, irritation of throat and aching of body.
Fluorides ?Fluoride compounds evolved may cause skin and eye burns, pulmonary edema and bronchitis.
Nickel, Nickel Compounds ?Metallic taste, nausea, tightness in chest, fever, allergic reactions.
Chromium ?Inhalation of fume with chromium VI compounds can cause irritation of the respiratory system, lung damage and asthma-like
symptoms. Swallowing chromium VI salts can cause sever injury or death. Dust on the skin can form ulcers. Eyes may be burned by chromium
VI compounds. Allergic reactions are likely in some people from chromium compounds.
Copper ?Metal fume fever can be caused by fresh copper oxide.
Barium ?Aching eyes, rhinitis, frontal headache, wheezing, laryngeal spasms, salivation or anorexia.
Silica ?None are known.
Molybdenum ?None are known. Treat as a nuisance dust or fume.
Titanium Dioxide ?None are known. Treat as a nuisance dust or fume.
Aluminum, Aluminum Oxide ?None are known. Treat as a nuisance dust or fume.
Magnesium, Magnesium Oxide ?None are known. Treat as a nuisance dust or fume.
Long ?Term (chronic Overexposure effects ?br>
Welding Fume ?Excess levels may cause bronchial asthma, lung fibrosis, pneumoconiosis, or `siderosis'.
Iron, Iron Oxide ?Siderosis or deposits of iron in lungs, which is believed to affect pulmonary function. Lungs will clear in time when exposure
to
Iron fumes and its compounds ceases. Iron and magnetite (Fe3O4) are not regarded as fibrogenic materials.
Manganese ?Central nervous system effects referred to as `manganism'. Symptoms include muscular weakness and tremors. Behavioral changes
and changes in handwriting may also appear. Employees overexposed to manganese should receive quarterly medical examinations for early
detection of manganism.
Fluorides ?Serious bone erosion (Osteoporosis) and mottling of teeth.
Nickel, Nickel Compounds ?Lung fibrosis or pneumoconiosis. Studies of nickel refinery workers indicated a higher incidence of lung and nasal
cancers.
Chromium ?Ulceration and perforation of the nasal septum. Respiratory irritation may occur with symptoms resembling asthma. Studies have
shown that chromate production workers exposed to chromium VI compound have an excess of lung cancers. Chromium VI compounds are more
readily absorbed through the skin that chromium III compounds. Good practice requires the reduction of employee exposure to chromium III and
VI compounds.
Copper ?No adverse long-term health effects have been reported in the literature.
Barium ?Exposure to soluble barium compounds may cause nervous disorders and may have deleterious effects on the heart, circulatory and
muscular system.
Silica ?Overexposure to respirable crystalline silica may result in silicosis. Respirable crystalline silica is a known human carcinogen.
Molybdenum ?Treat as a nuisance dust. Little adverse effect on lungs. Does not produce significant organic disease or toxic effect when
exposures are kept under reasonable control.
Aluminum, Aluminum Oxide ?Treat as a nuisance dust. Little adverse effect on lungs. Does not produce significant organic disease or toxic
effect when exposures are kept under reasonable control.
Magnesium, Magnesium Oxide - Treat as a nuisance dust. Little adverse effect on lungs. Does not produce significant organic disease or toxic
effect when exposures are kept under reasonable control.
Emergency and First Aid Procedures
Call for medical aid. Employ first aid techniques recommended by the American Red Cross.
Eyes and Skin: If irritation or flash burns develop after exposure, consult a physician.
Carcinogenicity
Hexavalent chromium compounds are listed as known human carcinogens by IARC and NTP. Nickel compounds are listed as known human
carcinogens by IARC. Nickel and certain nickel compounds are reasonably anticipated to be human carcinogens by NTP. Crystalline silica is
listed as a known human carcinogen by IARC and NTP. Welding fumes (non-specific) are listed by IARC as possibly carcinogenic to humans.
California Proposition 65

SECTION VII ?Precautions for Safe Handling and Use / Applicable Control Measures
Read and understand the manufacturer's instructions and the precautionary label on the product. Refer to ANSI Z49.1 published by the American
Welding Society.
VENTILATION: Use enough ventilation, local exhaust at the arc or both to keep fumes and gases below TLV's in the worker's breathing zone
and the general area. Train the welder to keep his head out of the fumes.
RESPIRATORY PROTECTION: Use respirable fume respirator or air supplied respirator when welding in confined spaces or where local
exhaust or ventilation does not keep exposure below TLV.
PROTECTIVE CLOTHING: Wear head, hand and body protection that help prevent injury from radiation, sparks, and electrical sparks. At a
minimum this includes welder's gloves and a protective face shield, and may include are protectors, aprons, hats, shoulder protection, as well as dark,
non-synthetic clothing. Train the welder not to touch live electrical parts and to insulate himself from the work and ground.
PROCEDURE FOR CLEAN UP OF SPILLS AND 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.
Special Precautions ?IMPORTANT ?Maintain exposure below the PEL/TLV. Use industrial hygiene monitoring to ensure that your use of
this material does not create exposures that exceed the PEL/TLV. Always use exhaust ventilation.
