**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Appearance: colorless to black.
Caution! May cause lung damage. May cause eye and
skin irritation.
May cause respiratory and digestive tract
irritation. May cause
cancer based on animal studies.
Target Organs: No data found.
Potential Health Effects
Eye:
Dust may cause mechanical irritation.
Skin:
Dust may cause mechanical irritation.
Ingestion:
May cause irritation of the digestive tract.
Inhalation:
Dust is irritating to the respiratory tract. May cause lung damage.
Contains crystalline silica which may lead to respiratory
abnormalities and silicosis.
Chronic:
Chronic inhalation of dust may lead to silicosis. May cause lung
damage. 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:
Flush skin with plenty of soap and water for at least 15 minutes
while removing contaminated clothing and shoes. Get medical aid if
irritation develops or persists. Wash clothing before reuse.
Ingestion:
Do
NOT induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Get medical aid.
Inhalation:
Remove from exposure to fresh air immediately. If not breathing,
give artificial respiration. If breathing is difficult, give oxygen.
Get medical aid. Do NOT use mouth-to-mouth resuscitation.
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. Material will not burn. Use extinguishing media
appropriate to the surrounding fire. Dousing metallic fires with
water may generate hydrogen gas, an extremely dangerous explosion
hazard.
Extinguishing Media:
Substance is noncombustible; use agent most appropriate to
extinguish surrounding fire.
Autoignition Temperature:Not
available.
Flash Point:
400 deg C ( 752.00 deg F)
Explosion Limits, lower:Not
available.
Explosion Limits, upper:Not
available.
NFPA Rating: (estimated) Health:
1; Flammability: 0; Reactivity: 0
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use
proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Use only in a well-ventilated area. Minimize dust generation and
accumulation. Avoid contact with skin and eyes. Avoid ingestion and
inhalation.
Storage:
Store in a dry area.
**** 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 exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
