NFPA NUMERCIAL CODES: Health Hazard 鈥? 0
Fire Hazard - 1
Reactivity Hazard - 0

V. REACTIVITY DATA
The term 鈥渉azardous鈥? should be interpreted as a term required and defined in the OSHA Hazard
Communication Standard (29 CFR Part 1910.1200) and does not necessarily imply the existence of any
hazard. These products as shipped are stable, non hazardous, nonflammable, non-explosive and
non-reactive.
Hazardous Decomposition Products
Exposure limit: Welding fumes and gases cannot be classified simply. The composition and quantity of
both are dependent upon the metal being welded, the process, procedure and electrodes used. Other
conditions that 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 work area, the quality and amount of ventilation, the position of the welder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 and degreasing activities.)
When the Wire is consumed, the fume and gas decomposition products generated are different in percent
and form from the ingredients listed in Section II. Fume and gas decomposition products and not the
ingredients in the wire, are important. The concentration of a given fume or gas component may decrease
or increase by many times the original concentration in the powder. Also, new compounds not in the wire
may form. Decomposition products of normal operation include those originating from the volatilization,
reaction, or oxidation of the material shown in Section II, plus those from the base metal and coating, etc.,
as noted above.
Reasonably expected fume constituents of these products would include complex oxides of iron,
manganese and silicon; secondarily complex oxides of chromium, nickel, molybdenum, titanium, calcium,
sodium and potassium.

The present OSHA PEL for hexavalent chromium (CR+6) is 0.05 mg/m that will result in a significant
3 3
reduction from the 5mg/m general welding fume (NOC) level. The limit of 0.05 mg/m for hexavalent
chromium in these wires comes from the limit shown in OSHA table Z-2, which is for 0.1mg of Cr03 + which
3
calculates to 0.05 mg of Cr+6/m .
3 3
OSH PEL for nickel metal and soluble compounds is 1 mg/m . The ACGIH TLV for nickel metal is 1 mg/m
3
and TLV for soluble compounds is 0.1 mg/m . These limitations will also result in a significant reduction
3
from the 5 mg/m general welding fume (NOC) level.
Gaseous reaction products may include carbon monoxide and carbon dioxide. Ozone and nitrogen oxides
may be formed by the 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鈥檚 helmet if worn or in the worker鈥檚 breathing zone.

VI. HEALTH HAZARD DATA
Electric arc welding or oxy fuel welding may create one or more of the following health hazards:
FUMES AND GASES: can be dangerous to your health. COMMON ENTRY IS BY INHALATION.
SHORT TERM (ACUTE): over exposure to welding fumes may result in discomforts such as: dizziness,
nausea, or dryness or irritation of nose, throat, or eyes.
Chromates present in the fume can cause metallic taste nausea, tightness in the chest, fever and allergic
reactions.
Fluorides can cause pulmonary edema bronchitis.
LONG TERM (CHRONIC): over exposure to welding fumes can lead to siderosis (iron deposits in the lung)
and affect pulmonary function.
Long term over exposure to manganese compound may affect the central nervous system. Symptoms
3
include muscular weakness and tremors similar to Parkinson鈥檚 disease. Behavioral changes and changes
in handwriting may also appear. Employees exposed to manganese compounds should get quarterly
medical examinations for early detection of manganism.
Studies have shown that production workers exposed to hexavalent chromium compounds have an
increased incidence of lung cancers. Chromates may cause an ulceration and perforation of the nasal
septum. Liver damage and allergic skin rash have been reported. Chromium VI compounds are required
by OSHA to be considered carcinogenic.
Long term over exposure to nickel compounds may cause lung fibrosis or pneumoconiosis. Studies of
nickel refinery workers indicated a higher incidence of lung and nasal cancers. Nickel and its compounds
are considered as carcinogenic as required by OSHA.
Repeated over exposure to fluoride fumes may cause serious bone erosion and excessive calcification of
the bones and ligaments of the ribs, pelvis and spinal column. Fluorides may also cause skin rash.
Shielding gases such as argon, helium and carbon dioxide are asphyxiates and adequate ventilation must
be provided.
THRESHOLD LIMIT VALUE 鈥? the ACGIH 1985-86 recommended limit for welding fumes not otherwise
3
classified (NOC) is 5 mg/m . TLV-TWA鈥檚 should be used as a guide in the control of health hazards and
not as fine lines between safe and dangerous concentrations. See Section V for specific fume constituents
that may modify this TLV-TWA.
ARC RAYS 鈥? can injure eyes and burn skin.
HEAT RAYS 鈥? (infrared radiation from flame or hot metal) can injure eyes.
ELECTRICAL SHOCK 鈥? can kill.
NOISE 鈥? can damage hearing.
CARCINOGENICITY 鈥? Chromium and nickel and their compounds are on the IARC (International Agency
for Research on Cancer) list and the NTP (National Toxicology Program) list as posing a carcinogenic risk to
humans.
EMERGENCY AND FIRST AID PROCEDURES 鈥? Call for medical aid. Employ first aid techniques
recommended by the American Red Cross.
WARNING: This product may contain or may produce a chemical known to the State of California to cause
cancer. (California Health & Safety Code 35249.5 et seq.)
VII. PRECAUTIONS FOR SAFE HANDLING AND USE/APPLICABLE CONTROL
MEASURES
Read and understand the manufacturer鈥檚 instructions and the precautionary label on the product. See
American National Standard Z49.1, Safety in Welding and Cutting published by the American Welding
Society, P.O. Box 351040, Miami, FL 33135 and OSHA Publication #2206 (29CFR1910). U.S.
Government Printing Office, Washington, D.C. 20401 for more details on many of the following:
VENTILATION 鈥? Use enough ventilation, local exhaust at the arc, or both, to keep the fumes and gases
below TLV鈥檚 in the worker鈥檚 breathing zone and the general area. Train the welder to keep his head out of
the fumes.
RESPIRATORY PROTECTION 鈥? Use respirator fume respirator or air-supplied respirator when welding in
confines space or where local exhaust or ventilation does not keep exposure below TLV.
EYE PROTECTION 鈥? Wear helmet or use face shield with filter lens. As a rule of thumb, start with a shade
that 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.
PROTECTIVE CLOTHING 鈥? Wear head, hand and body protection, which help to prevent injury from
4
radiation, sparks, and electrical shock. See ANSI Z49.1. 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.
PROCEDURE FOR CLEANUP OF SPILLS OR LEAKS 鈥? Not applicable.
WASTE DISPOSAL METHOD 鈥? Prevent waste from contaminating surrounding environment. Discard
compliance with federal, state and local regulations.
