3. HAZARDS IDENTIFICATION
Emergency Overview:
Eye Contact:
Skin Contact:
Ingestion Acute:Inhalation Acute:Tan, odorless powder. May cause moderate irritation to eyes, skin, and digestive tract.
May cause abrasion to the eyes.
May cause moderate irritation to the skin.
May cause irritation to mouth, esophagus, and stomach.
Excessive short-term airborne dust may cause irritation to upper respiratory track and short-term
acute silicosis.

Chronic Hazards:

Silica:This product contains trace levels of crystalline silica; once inhaled, cristobalite can remain in thelungs causing scarring, stiffening and difficulty breathing. The most common type of silicosis
develops following repeated inhalation over time. Repeated inhalation of crystalline silica can also
increase the risks of developing respiratory cancer. Animal studies indicate that fused silica may
cause lung fibrosis. Avoid dust creation. Do not inhale dusts from this product. Do not use
compressed air or dry sweeping to remove dusts from the work area. Use wet clean-up methods toremove dusts. IARC and NTP classify respirable crystalline silica as a confirmed or known humancarcinogen. Although OSHA has not promulgated a specific standard for crystalline silica, materials
that contain >= 0.1% crystalline silica should be treated as a confirmed carcinogen for hazard
communication purposes.
Zircon:Zircon contains naturally occurring radioactive materials (NORM) in the uranium and thorium series,
in equilibrium, at typical specific activities of 0.3 to 0.7 Bq/g thorium (85-165 ppm) and 0.3 to 3.5 Bq/guranium (28-281 ppm). Zircon is exempt from Nuclear Regulatory Commission (NRC) regulations forsource material per 10 CFR 40, since it falls under the definition of “unimportant quantity source1material” containing less than 0.05% uranium or thorium. The main radiological hazard from theproduct is internal exposure from small amounts of alpha particles given off by inhaled dust.
Industrial hygiene practices aimed at control of airborne dust can lessen the potential for exposure.
Overexposure by inhalation to inhaled dusts containing radioactive uranium or thorium may causelung cancer. Low level gamma radiation in proximity to bulk stockpiles of zircon may present a lesser,
external exposure that can be managed by limiting close proximity for long time periods to large
volumes of material. IARC and NTP do not list Zircon as a carcinogen.

4. FIRST AID MEASURES
Eye Exposure:
Hold eyelids open and flush with a steady, gentle stream of water for at least 15 minutes. Seek immediate medical attention, preferably with an
ophthalmologist. If a physician is not immediately available, eye irrigation should be continued for an additional 15 minutes.
Skin Exposure:
Immediately wipe excess material off skin with a dry cloth then wash with plenty of soap and water for at least 5 minutes. See medicalattention if irritation develops or persists. Remove contaminated clothing and shoes and clean thoroughly before re-use.
Inhalation:
Remove from immediate source of exposure and assure that victim is breathing. If not breathing, administer cardio-pulmonary resuscitation(CPR). If breathing is difficult, administer oxygen if available. Seek medical attention.
Ingestion:
If swallowed, do not induce vomiting. If victim is conscious and alert, give 1-2 glasses of water to drink. Do not give anything by mouth to an
unconscious person. Seek medical attention immediately. Do not leave victim unattended. To prevent aspiration of swallowed product, lay
victim on side with head lower than waist. Vomiting may occur spontaneously. If vomiting occurs and the victim is conscious, give water tofurther dilute the chemical.
Medical Conditions Possibly Aggravated by Exposure:
Inhalation of product may aggravate existing chromic respiratory problems such as asthma, emphysema or bronchitis. Skin contact may
aggravate existing skin disease.

6. ACCIDENTAL RELEASE MEASURES
Personal Protection:
Spill Cleanup:

Wear goggles, protective clothing, and chemical resistant gloves. Use NIOSH approved respirator toprevent inhalation of dust.
Collect material with precaution against breathing dust and dispose in accordance with federal, stateand local regulations.

7. HANDLING AND STORAGE
Handling:
Storage:

Avoid contact with eyes, skin and clothing. Avoid breathing dust. Keep container closed. Promptly
clean residue from closures with cloth dampened with water. Promptly clean up spills.
Store in an area that is cool, dry, and well ventilated. Keep containers closed. Store in clean plastic
or metal containers.

8. EXPOSURE CONTROLS / PERSONAL PROTECTION
Engineering Controls:
Respiratory Protection:
Skin Protection:
Eye Protection:

Use with adequate ventilation; mechanical dust collector is recommended. Keep containers closed.
Safety shower and eyewash fountain should be within direct access.
If exposure limits are exceeded and local ventilation is unavailable, a supplied-air respirator or a selfcontained NIOSH-approved particulate cartridge respirator is recommended.
Wear protective clothing and gloves.
Wear chemical goggles.

10. STABILITY AND REACTIVITY
Chemical Stability:
Conditions to Avoid:

This material is stable under all conditions of use and storage.
Keep exposure to dust levels below TLV. Avoid rapid heating of the cement that may cause spallingor eruption of the cement because of rapid hydration.
Materials to Avoid:
Reacts with water to hydrate as part of the cement reaction.
oHazardous Decomposition Products: Water of hydration will be released as steam above 250 C.
Hazardous Polymerization:Will not occur.

Inhalation:

Acute silicosis has been reported for exposure to extremely high crystalline silica concentrations
particularly when the particle size of the dust is very small. Acute silicosis is rapidly progressive withdiffuse pulmonary involvement and does not form classical silicotic nodules. The disease is often
complicated by tuberculosis and can develop only months after the initial exposure with the possibilityof death within 1 or 2 years. This product contains < 0.50% crystalline silica. Acute silicosis may notoccur at the concentrations present.

Chronic:

Classic silicosis is characterized by the formation of scattered silica containing nodules of scar tissue
in the lungs ranging in size from microscopic to greater than 1 cm. Simple silicosis (nodules < 1 cm)
is generally asymptomatic but may progress to debilitating complicated silicosis (nodules > 1 cm) with3

or without continued exposure. Historically, workers who developed silicosis had greatly increased
risks of developing an accompanying tuberculosis infection (silicotuberculosis).
IARC has found inadequate evidence to link exposure to amorphous silica to cancer in animals.
Limited data is available concerning the health effects of fused silica in animals or humans; however,animal studies indicate a fibrogenic potential less than that of quartz. IARC has found inadequate
evidence to link exposure to amorphous silica to cancer in animals.
.

Overexposure by inhalation to inhaled dusts containing radioactive uranium or thorium may causelung cancer. Low level gamma radiation in proximity to bulk stockpiles of zircon may present a lesser,
external exposure that can be managed by limiting close proximity for long time periods to large
volumes of material. IARC and NTP do not list Zircon as a carcinogen.

Subchronic:

No data.

Other:

Silica particles <10 microns are considered respirable; however, particles retained in the lungs are
generally much smaller. Silica particles retained in the human lung have median diameters of 0.5-0.7microns.
