EMERGENCY OVERVIEW
Appearance: white crystalline powder crystalline powder.
Warning! Flammable solid. May cause eye and skin
irritation. May cause respiratory and digestive tract irritation. May
cause central nervous system depression. Moisture sensitive. Chronic
inhalation of crystalline silica may lead to fibrotic lung disease,
silicosis or cancer.
Target Organs: Central nervous system, lungs.
Potential Health Effects
Eye:
May cause chemical conjunctivitis and corneal damage.
Skin:
May cause irritation and dermatitis. May cause cyanosis of the
extremities.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. Ingestion of large amounts may cause CNS depression.
Inhalation:
Aspiration may lead to pulmonary edema. Contains crystalline silica
which may lead to respiratory abnormalities and silicosis.
Inhalation of dusts cause severe irritation of the upper respiratory
tract, gastrointestinal disturbances, albuminuria, gradual loss of
weight, and increasing weakness. May cause burning sensation in the
chest.
Chronic:
Chronic inhalation of dust may lead to silicosis. May cause
silicosis-disabling pulmonary fibrosis characterized by fibrotic
changes and miliary nodules in the lungs, dry cough, shortness of
breath, emphysema, decreased chest expansion and increased
susceptibility to tuberculosis.
Section 4 - First Aid Measures
|
Eyes:
Flush eyes with plenty of water for at least 15 minutes, occasionally
lifting the upper and lower eyelids. Get medical aid.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Wash clothing
before reuse.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical
aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and
drink 2-4 cupfuls of milk or water.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
|
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Dusts at sufficient concentrations can form
explosive mixtures with air. During a fire, irritating and highly
toxic gases may be generated by thermal decomposition or combustion.
Use water spray to keep fire-exposed containers cool. Containers may
explode in the heat of a fire. May be ignited by friction, heat,
sparks, or flame. May react violently or explosively on contact with
water. May re-ignite after fire is extinguished.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Use dry sand,
Met-L-X powder, or G-1 graphite powder. Do NOT get water inside
containers. DO NOT USE WATER, CO2, OR FOAM DIRECTLY ON FIRE ITSELF.
Use dry sand, graphite powder, dry sodium chloride-based
extinguishers.
Flash Point: Not applicable.
Autoignition Temperature: > 150 deg C (> 302.00 deg F)
Explosion Limits, Lower:Not available.

NFPA Rating:
(estimated) Health: 1; Flammability: 3; Instability: 0
Section 6 - Accidental Release Measures
|
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Very fine particles can cause a fire or explosion. Eliminate all
ignition sources. Clean up spills immediately, observing precautions
in the Protective Equipment section. Sweep up, then place into a
suitable container for disposal. Avoid generating dusty conditions.
Use a spark-proof tool. Provide ventilation. Do not get water inside
containers.
Section 7 - Handling and Storage
|
Handling:
Remove contaminated clothing and wash before reuse. Use with
adequate ventilation. Ground and bond containers when transferring
material. Use spark-proof tools and explosion proof equipment. Avoid
contact with eyes, skin, and clothing. Empty containers retain
product residue, (liquid and/or vapor), and can be dangerous. Keep
container tightly closed. Keep away from heat, sparks and flame.
Avoid ingestion and inhalation. Do not allow contact with water. Do
not pressurize, cut, weld, braze, solder, drill, grind, or expose
empty containers to heat, sparks or open flames. Keep from contact
with moist air and steam.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances.
Flammables-area. Store protected from moisture.
Section 8 - Exposure Controls, Personal Protection
|
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate general or
local explosion-proof ventilation to keep airborne levels to
acceptable levels.
