Potential Health Effects
----------------------------------

Inhalation:
Acute pneumoconiosis from overwhelming exposure
to silica dust has occurred. Coughing and irritation of throat are early
symptoms.
Ingestion:
No adverse health effects expected.

Skin Contact:
No adverse effects expected.
Eye
Contact:
May cause irritation, redness and pain.
Chronic
Exposure:
Inhalation of quartz is classified as a human carcinogen.
Chronic exposure can cause silicosis, a form of lung scarring that can cause
shortness of breath, reduced lung function, and in severe cases, death.

Aggravation of Pre-existing Conditions:
Inhalation may increase
the progression of tuberculosis; susceptibility is apparently not increased.
Persons with impaired respiratory function may be more susceptible to the
effects of this substance. Smoking can increase the risk of lung injury.

4. First Aid Measures

Inhalation:
Remove to fresh air. If not breathing, give
artificial respiration. If breathing is difficult, give oxygen. Get medical
attention.
Ingestion:
If large amounts were swallowed, give
water to drink and get medical advice.
Skin Contact:
Wash
exposed area with soap and water. Get medical advice if irritation develops.

Eye Contact:
Wash thoroughly with running water. Get medical
advice if irritation develops.

5. Fire Fighting Measures

Fire:
Not considered to be a fire hazard.

Explosion:
Not considered to be an explosion hazard.

Fire Extinguishing Media:
Use any means suitable for
extinguishing surrounding fire.
Special Information:
In the
event of a fire, wear full protective clothing and NIOSH-approved
self-contained breathing apparatus with full facepiece operated in the
pressure demand or other positive pressure mode.

6. Accidental Release Measures

Ventilate area of leak or spill. Wear appropriate personal
protective equipment as specified in Section 8. Spills: Sweep up and
containerize for reclamation or disposal. Vacuuming or wet sweeping may be
used to avoid dust dispersal.

7. Handling and Storage

Keep in a tightly closed container, stored in a cool, dry,
ventilated area. Protect against physical damage. Use dustless systems for
handling, storage, and clean up so that dust does not exceed the PEL. Use
adequate ventilation and dust collection. Practice good housekeeping. Do not
allow dust to collect on walls, floors, sills, ledges, machinery, or
equipment. Maintain, clean and test respirators in accordance with OSHA
regulations. Maintain and test ventilation and dust collection equipment. Wash
clothing that has become dusty; do not breathe the dust from clothing.
Containers of this material may be hazardous when empty since they retain
product residues (dust, solids); observe all warnings and precautions listed
for the product.

8. Exposure Controls/Personal Protection

Airborne Exposure Limits:
-OSHA Permissible Exposure
Limit (PEL):
Total dust: 30mg/m3/(%SiO2 + 2)
Respirable Fraction: 10
mg/m3/(%SiO2 + 2)

-ACGIH Threshold Limit Value (TLV):
0.025 mg/m3
(TWA) respirable dust, A2 -Suspected Human Carcinogen.
Ventilation
System:
A system of local and/or general exhaust is recommended to
keep employee exposures below the Airborne Exposure Limits. Local exhaust
ventilation is generally preferred because it can control the emissions of the
contaminant at its source, preventing dispersion of it into the general work
area. Please refer to the ACGIH document, Industrial Ventilation, A Manual
of Recommended Practices, most recent edition, for details.

Personal Respirators (NIOSH Approved):
If the exposure limit is
exceeded and engineering controls are not feasible, a half-face high
efficiency particulate respirator (NIOSH type N100 filter) may be worn for up
to ten times the exposure limit or the maximum use concentration specified by
the appropriate regulatory agency or respirator supplier, whichever is lowest.
A full-face piece high efficiency particulate respirator (NIOSH type N100
filter) may be worn up to 50 times the exposure limit, or the maximum use
concentration specified by the appropriate regulatory agency or respirator
supplier, whichever is lowest. If oil particles (e.g. lubricants, cutting
fluids, glycerine, etc.) are present, use a NIOSH type R or P filter. For
emergencies or instances where the exposure levels are not known, use a
full-facepiece positive-pressure, air-supplied respirator. WARNING:
Air-purifying respirators do not protect workers in oxygen-deficient
atmospheres. Where respirators are required, you must have a written program
covering the basic requirements in the OSHA respirator standard. These include
training, fit testing, medical approval, cleaning, maintenance, cartridge
change schedules, etc. See 29CFR1910.134 for details.
Skin
Protection:
Wear protective gloves and clean body-covering clothing.

Eye Protection:
Use chemical safety goggles. Maintain eye wash
fountain and quick-drench facilities in work area.
