ACUTE EFFECTS:
HEALTH HAZARDS, GENERAL:
Particulates may cause mechanical irritation to the eyes, nose, throat and lungs. Particulate inhalation may lead to
pulmonary fibrosis, chronic bronchitis, emphysema and bronchial asthma. Dermatitis and asthma may result from short
contact periods.
INHALATION: May be irritating to the respiratory tract if inhaled.
INGESTION: May cause gastric distress, nausea and vomiting if ingested.

EYES: May be irritating to the eyes.
CHRONIC EFFECTS:
CARCINOGENICITY:
IARC: Not listed. OSHA: Not regulated. NTP: Not listed.
ATTENTION! CANCER HAZARD. CONTAINS CRYSTALLINE SILICA WHICH CAN CAUSE CANCER. Risk
of cancer depends on duration and level of exposure.
IARC Monographs, Vol. 68, 1997, concludes that there is sufficient evidence that inhaled crystalline silica in the form of
quartz or cristobalite from occupational sources causes cancer in humans. IARC classification Group 1.

4. FIRST AID MEASURES

GENERAL: Persons seeking medical attention should carry a copy of this MSDS with them.
INHALATION: Move the exposed person to fresh air at once. Perform artificial respiration if breathing has stopped. Get medical attention. INGESTION: Drink a couple of glasses water or milk. Do not give victim anything to drink of he is unconscious. Get medical attention. SKIN: Wash skin thoroughly with soap and water. Remove contaminated clothing. Get medical attention if any discomfort continues.
EYES: Promptly wash eyes with lots of water while lifting the eye lids. Continue to rinse for at least 15 minutes. Get medical attention if any discomfort continues.

7. HANDLING AND STORAGE

HANDLING PRECAUTIONS:
Avoid handling causing generation of dust. Wear full protective clothing for prolonged exposure and/or high
concentrations. Eye wash and emergency shower must be available at the work place. Wash hands often and change
clothing when needed. Provide good ventilation. Mechanical ventilation or local exhaust ventilation is required.
STORAGE PRECAUTIONS:
Store at moderate temperatures in dry, well ventilated area. Keep in original container.

3 mg/m3 total dust

INGREDIENT COMMENTS:
* OSHA PELs for Mineral Dusts containing crystalline silica are 10 mg/m3 / (%SiO2+2) for quartz and 1/2 the calculated
quartz value for cristobalite and tridymite. * mppcf = millions of particles per cubic foot of air. PROTECTIVE EQUIPMENT:
ENGINEERING CONTROLS:
Use appropriate engineering controls such as, exhaust ventilation and process enclosure, to reduce air contamination and keep worker exposure below the applicable limits.

VENTILATION: Supply natural or mechanical ventilation adequate to exhaust airborne product and keep exposures below the applicable limits.
RESPIRATORS: Use at least a NIOSH-approved N95 half-mask disposable or reuseable particulate respirator. In work environments containing oil mist/aerosol use at least a NIOSH-approved P95 half-mask disposable or reuseable particulate respirator. For exposures exceeding 10 x PEL use a NIOSH-approved N100 Particulate Respirator.
PROTECTIVE GLOVES:
Use suitable protective gloves if risk of skin contact.
EYE PROTECTION:
Wear dust resistant safety goggles where there is danger of eye contact.
PROTECTIVE CLOTHING:
Wear appropriate clothing to prevent repeated or prolonged skin contact.
HYGIENIC WORK PRACTICES:
Wash promptly with soap and water if skin becomes contaminated. Change work clothing daily if there is any possibility of contamination.
