PROTECTIVE CLOTHING: Wear head, hand, and body protection which help to prevent injury from radiation, sparks, and
electrical shock. See ANSI Z49.1. At a minimum, this includes welders’ 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 themselves from work and ground, especially if clothing and gloves are wet.
WORK HYGIENIC PRACTICES: Do not eat or consume beverages in the work area.
EXPOSURE GUIDELINES: Use industrial hygiene monitoring equipment to ensure that exposure does not exceed applicable
national exposure limits. When the electrode is consumed, fume and gas decomposition products generated are different in percent
and form from the ingredients listed in Section 3. The fume and decomposition products, not the ingredients in the electrode, are
important. Decomposition products include those originating from the volatilization, reaction, or oxidation of materials in Section 3,
plus those from the base metal, etc., as noted above. These components are virtually always present as complex oxides and not as
metals (Characterization of Arc Welding Fume: American Welding Society). Reasonably expected fume constituents of the fume
could include complex oxides of iron and manganese. The following limits can be used as guidance. Refer to Section 11 for more
information about welding fumes.

If using this rod on stainless steel or other alloyed containing base material, chromium, nickel and other fumes may be generated.
Gaseous reaction products may include carbon monoxide and carbon dioxide. Ozone and nitrogen oxides may also be formed by radiation
from the arc. If used on chromium bearing steels, the fume limit for Cr VI (5 micrograms/m³) may be reached before the ACGIH
recommended general welding fume limit of 5 mg/m³ is reached. Monitor fume levels and Cr VI level. Train workers about the hazards
of Cr (VI). Read and comply with the OSHA permissible exposure limits for hexavalent chromium (CrVI), Fed. Reg. 71 – 10099
(specifically 29 CFR 1910.1026, 29 CFR 1915.1026, and 29 CFR 1926.1126). For CrVI, OSHA requires: “The employer
shall perform
initial monitoring to determine the 8-hour TWA exposure for each employee on the basis of a sufficient number of personal breathing zone
air samples to accurately characterize full shift exposure on each shift, for each job classification, in each work area”. Specialized
equipment is required for monitoring Cr (VI) concentration in the workplace. OSHA Analytical Method Number ID-215 for area and
breathing zone sampling and OSHA Analytical Method Number W4001 for wipe samples are listed on the OSHA website -
www.osha.gov
-as methods for measuring Cr(VI). This standard is complex and the employer should contact an occupational health professional for
doing the Cr(VI) monitoring and all other fume monitoring. Monitor fume levels. One recommended way to determine the composition
and quantity of fumes and gas 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, F1.2, F1.3, F1.4, and F1.5, available from the "American Welding Society," 550 N.W. LeJeune
Road, Miami, FL 33126).
Exposure limits are subject to change. Contact ACGIH, OSHA, NIOSH, and IARC for current values.
SECTION 9: PHYSICAL AND CHEMICAL PROPERTIES

MELTING POINT: > 1800 °F (> 1000 °C)
SECTION 10: STABILITY AND REACTIVITY
GENERAL: These items are only intended for normal welding purposes.
STABILITY: Stable under normal conditions.
HAZARDOUS POLYMERIZATION: Will not occur
REACTIVITY: Contact with chemical substances like acids or strong bases could cause generation of gas.
