Section 2 -
Composition, Information on Ingredients
Symbols: None listed.
Risk Phrases: None listed.
Section 3 - Hazards
Appearance: white to yellow crystals. Caution! Light
sensitive. Air sensitive. This is expected to be a low hazard for usual
industrial handling. May cause eye, skin, and respiratory tract irritation.
Strong reducing agent. Fire and explosion risk in contact with oxidizing agents.
Target Organs: None.
Eye: May cause eye irritation.
Skin: May cause skin irritation. Low hazard for usual
Ingestion: Ingestion of large amounts
may cause gastrointestinal irritation. Low hazard for usual industrial handling.
Large doses may cause diarrhea and acidification of the urine which may cause
stones in the urinary tract.
Inhalation: May cause
respiratory tract irritation. Low hazard for usual industrial handling.
Chronic: No information found.
Section 4 - First Aid
Eyes: Flush eyes with plenty of water for at least
15 minutes, occasionally lifting the upper and lower eyelids. If irritation
develops, get medical aid.
Skin: Flush skin with plenty of
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: Never give anything by mouth to an unconscious
person. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink
2-4 cupfuls of milk or water. Wash mouth out with water. Get medical aid if
irritation or symptoms occur.
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 if cough or
other symptoms appear.
Notes to Physician: Treat
symptomatically and supportively.
Section 5 - Fire
Information: As in any fire, wear a self-contained breathing apparatus
in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective
gear. During a fire, irritating and highly toxic gases may be generated by
thermal decomposition or combustion. This material in sufficient quantity and
reduced particle size is capable of creating a dust explosion. Powerful reducing

Section 6 -
Accidental Release Measures
Information: Use proper personal protective equipment as indicated in
Spills/Leaks: Vacuum or sweep up material and
place into a suitable disposal container. Avoid generating dusty conditions.
Section 7 - Handling
Handling: Wash thoroughly after handling. Remove
contaminated clothing and wash before reuse. Minimize dust generation and
accumulation. Avoid contact with eyes, skin, and clothing. Keep container
tightly closed. Use with adequate ventilation. Avoid breathing dust.
Storage: Store in a cool, dry, well-ventilated area away
from incompatible substances. Store protected from moisture. Store protected
from light. Store under an inert atmosphere.
Section 8 - Exposure
Controls, Personal Protection
Controls: Facilities storing or utilizing this material should be
equipped with an eyewash facility and a safety shower. Use adequate ventilation
to keep airborne concentrations low.
