SOLUBILITY IN WATER: Not Soluble
SOFTENING POINT: 2400 F

IV. HEALTH HAZARD DATA
ROUTE OF EXPOSURE: Inhalation of dusts or fumes.
EFFECTS OF OVEREXPOSURE:
Acute Effect: Excessive inhalation of metal fumes can produce an acute reaction known as 鈥渕etal fume fever鈥?.
Symptoms consist of chills and fever (very similar to and easily confused with flu symptoms) which come on a few hours
after large exposures.
Chronic Effec ts: Only after six to ten years of exposure to iron dust or fume does on e present any signs of
pneumoconiosis (i.e. siderosis). Physical examinations of those exposed to iron dust have not indicated any disability.
Excessive and repeated inhalation of chromium fume or dust may cause severe irritation, ulceration or cancer in the
respiratory system. It is generally believed that the hexavalent form of chromium (Cr+6) are responsible for these effects.
It is uncertain whether metallic chromium in dust form can cause the same effects noted above.
Excessive and prolonged inhalation of manganese (generally over two years exposure) can cause damage to the central
nervous system. The pathology resembles Parkinson鈥檚 Disease. Also, workers routinely exp osed to high concentrations
of manganese display an unusually high incidence of respiratory disease.
Molybdenum has caused toxicity (anemia and poor growth) in farm animals, but there are no data documenting toxicity
to humans due to industrial exposure.
Excessive inhalation of nickel fumes has been associated with respiratory cancer. Nickel is a potential sensitizer and
may cause allergic reactions.
Chronic exposure to tungsten dust has caused respiratory disorders characterized by cough, dyspnea and wheezing.
There is no correlation between the onset of symptoms, the length of exposure and the development of interstitial fibrosis.
Dermatitis, primarily on the side of the neck, flexor parts of the forearm and the back of the hand were also detected.
Vanadium dusts cause a persistent cough which can develop after five hours of exposure and may last up to ten days.
Pulmonary irritation also results from vanadium, but there are no deviations in pulmonary function or other laboratory
tests.
Zinc dust is a skin and respiratory tract irritant. It is relatively nontoxic. However, if oxidation occurs prior to
inhalation, one must deal with toxicities associated with zinc oxide such as metal fume fever, gastrointestinal disorders
and hepatic dysfunction.
V. EMERGENCY AND FIRST AID PROCEDURES
INHALATION: If acute overexposure to dust or fumes occurs, remove victim from the adverse environment and seek medical attention..
SKIN CONTACT: Wash area of contact thoroughly with soap and water. If irritation persists, seek medical attention.
EYE CONTACT: Flush immediately with running water for fifteen minutes. If irritation persists, seek medical attention.
INGESTION: N/A
VI. FIRE AND EXPLOSION HAZARD DATA
FLAMMABILITY CLASS:
FLASH POINT: N/A
EXTINGUISHING MEDIA: As for the surrounding fire, use dry powder for metal fires.
UNUSUAL FIRE HAZARD: Contact of molten product with water can cause an explosion hazard.
FIRE FIGHTING PROCEDURES: Wear full protective clothing including helmet, self-contained positive pressure-demand breathing
apparatus, protective clothing, and a face mask.
SPECIAL PROCEDURES: Firefighters should wear equipment to protect against noxious fumes.
PRODUCT OF COMBUSTION: Material will begin softening at approximately 2400 F, will proceed to a liquid and form irritating and
toxic gaseous metallic oxides at extremely high temperatures.
VII. SPILL OR LEAK PROCEDURES
LARGE/SMALL SPILL: Avoid creating dusts when cleaning spill. Small pieces may be collected using a broom and shovel.
Particulates and dust may be collected by using a vacuum with a HEPA filter. Place collected material in a closed container.
Minimal problems with spills of this product would occur because of its solid form. However, if there is a spill of dust, clean up using
methods which avoid dust generation and the use of water, such as vacuum. If airborne dust is generated during the clean up, use an
appropriate NIOSH-approved respirator.
Waste Disposal Method: Dispose of in accordance with appropriate federal, state and local regulations.
VIII. SPECIAL PROTECTION
VENTILATION: Local exhaust ventilation should be provided to keep workers exposures within allowable limits. Whenever dusts,
particulates, or fumes are generated, use appropriate local exhaust ventilation to keep exposures below the regulated limits.
RESPIRATORY PROTECTION: Use NIOSH/NSHA approved organic vapor respirators when vapor concentrations exceed the TLV.
EYE PROTECTION: Personal protective equipment should be worn when there is a reasonable probability of injury. Wear safety glasses
with side shields.
HAND PROTECTION: Wear leather or other appropriate work gloves, if necessary for type of operation.
OTHER: Protective clothing coveralls.
IX. CARCINOGENIC ASSESSMENT
Nickel and Chromium have been identified as suspect carcinogens by NTP and IARC.
X. REACTIVITY DATA
STABILITY: Stable under normal conditions of handling and use.
CONDITIONS TO AVOID: Poor ventilation.
INCOMPATIBILITY: Strong acids (produce hydrogen gas)
HAZARDOUS DECOMPOSITION PRODUCT: Metallic oxide.
HAZARDOUS POLYMERIZATION: Will not occur
XI. SPECIAL PRECAUTIONS
HANDLING AND STORAGE: Use good housekeeping practices to avoid excessive dust accumulation. As supplied, this product does not
present a health hazard. Processing of the product for final uses can include formation of dusts, particulates, or fumes, some of which may present
health hazards.
This information is taken from sources or based upon data believed to be reliable; however, DUCTMATE INDUSTRIES, INC. makes no warranty
as to the absolute correctness or sufficiency of any of the foregoing or that additional or other measures may not be required under particular
conditions.
