HAZARDS IDENTIFICATION
Potential Health Effects
The product, as shipped, does not pose an inhalation health hazard because it
contains essentially no particles in the respirable size range. However, if during
handling or use the particles are broken down to a size that can be inhaled, the
dusts may be harmful to the respiratory system. This product contains trace
quantities (90-110 pCi/g) of naturally occurring radioactive uranium and thorium
(less than or equal to 420 ppm total uranium and thorium or 0.042% w/w), and
(109-114 pCi/g) radium. Overexposure by inhalation to respirable dusts
containing radioactive uranium, thorium, and radium may cause lung cancer. Eye
contact with the product may cause irritation with discomfort, tearing, or blurring
of vision.
The predominant effect of overexposure to airborne respirable quartz in humans is
silicosis. Silicosis is a chronic fibrotic lung disease characterized by formation of
silica containing scar tissue in the lungs with symptoms of coughing, dyspnea,
wheezing, and nonspecific respiratory ailments. Gross acute overexposures to
quartz by inhalation may cause fatality. Epidemiological studies show that, in
addition to silicosis, there is limited evidence of excess lung cancer in
occupations involving exposures mainly to respirable quartz, such as stone cutters
and granite industry workers.
Individuals with preexisting conditions of the lungs may have increased
susceptibility to the toxicity of excessive exposures.
Observance of the 5 mg/m3 OSHA PEL for respirable dust will ensure that use of
this product is within limits established for exposure to respirable quartz and to
naturally occurring radioactive uranium, thorium, and radium.
Zircon is exempt from NRC regulations for source material per 10 CFR 40, since
it falls under the definition of unprocessed material containing less than 0.05%
uranium or thorium. However, observance of 2.2 - 2.8 mg/m3 of respirable dust
will under voluntary guidelines ensure that intake is less than 10% of the Annual
Ferro Electronic Materials MSDS Page 2 G ZIRCON MILLED COARSE/

Limits on Intake (ALIs) specified in 10 CFR 20.1502(b) and NRC Standards for
Protection Against Radiation for uranium, thorium, radium, and radioactive
daughter decay products.
Target Organs
None reported.
Primary Entry Route

FIRST AID MEASURES
Inhalation
If inhaled, immediately remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Call a physician.
Skin Contact
The compound is not hazardous by skin contact, but removal of particles and
cleansing of the skin after use is advisable.
FIRE FIGHTING MEASURES
Flammable Properties
Will not burn.
Extinguishing Media
As appropriate for combustibles in area.
Fire Fighting Instructions
None.

ACCIDENTAL RELEASE MEASURES
Safeguards (Personnel)
NOTE: Review FIRE FIGHTING MEASURES and HANDLING
(PERSONNEL) sections before proceeding with clean-up. Use appropriate
PERSONAL PROTECTIVE EQUIPMENT during clean-up.
Accidental Release Measures
Sweep up spillage. Avoid creation of respirable airborne dust.
HANDLING AND STORAGE
Handling (Personnel)
Avoid breathing dust. Wash thoroughly after handling. If handling respirable
flour, use of gloves and washing before eating, drinking, applying cosmetics, or
smoking is advisable to minimize dust inhalation from hands.
Storage
Store this product in closed containers. Protect containers from physical damage.
EXPOSURE CONTROLS/PERSONAL PROTECTION
Engineering Controls
Use sufficient ventilation to keep employee exposure below recommended limits.
When using this product as an abrasive blast agent in confined areas, airborne
dust levels should be controlled by physical enclosure of the abrasive blasting
operation. The enclosure should be exhaust ventilated in accordance with 29
CFR 1910.94 Ventilation (a) Abrasive Blasting.
Personal Protective Equipment
Eye/Face Protection
Wear safety glasses with side shields.
Respirators
A NIOSH/MSHA approved air-purifying respirator with a high efficiency
filter approved for radionuclides may be permissible under certain
circumstances where airborne concentrations are expected to exceed
exposure limits. Protection provided by air-purifying respirators is
limited. Use a positive pressure air-supplied respirator if there is any
potential for an uncontrolled release, exposure levels are not known, or
any other circumstances where air-purifying respirators may not provide
adequate protection.
OSHA requires a continuous flow air-line supplied respirator with hood
for protection in abrasive blasting operations. Refer to OSHA Standards
29 CFR 1910.94.

Wear impervious clothing, such as gloves, apron, boots, or whole bodysuit
as appropriate.

TOXICOLOGICAL INFORMATION
Animal Data
Ferro zirconium silicate products are made from zircon sands which contain low
levels of quartz (up to 0.5%). Effects noted in animals exposed to respirable
quartz by inhalation or intratracheal instillation included pulmonary fibrosis,
inflammation, edema, and emphysema. Lung tumors occurred in rats exposed by
inhalation for up to two years to levels of 12.4 or 51.6 mg/m3 of quartz. Also,
lung tumors were seen in studies in which quartz was instilled in the trachea of
rats. Quartz was positive in mammalian cell cultures for cell transformation and
chromosomal effects and was negative in cell culture assays for gene mutation in
bacteria and DNA damage in mammalian cells and in a whole animal assay for
chromosomal effects.
DISPOSAL CONSIDERATIONS
Waste Disposal
Treatment, storage, transportation, and disposal must be in accordance with
applicable federal, state, and local regulations. If approved, may be transferred to
a land disposal site.
NOTE:
Many states have, or are developing, new regulations for disposal of waste
containing Naturally Occurring Radioactive Materials (NORM) above
background levels. Consult and comply with current regulations.
