EMERGENCY OVERVIEW
Appearance: white to yellow crystals.
Caution! Strong reducing agent. Fire and explosion
risk in contact with oxidizing agents. May cause eye, skin, and
respiratory tract irritation. Light sensitive. Air sensitive.
Target Organs: None.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation. Low hazard for usual industrial handling.
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 Measures
|
Eyes:
Flush eyes with plenty of water for at least 15 minutes, occasionally
lifting the upper and lower eyelids. If irritation develops, get medi
cal 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 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. 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 agent.
Extinguishing Media:
Use extinguishing media most appropriate for the surrounding fire.
Flash Point: Not available.
Autoignition Temperature: 660 deg C ( 1,220.00 deg F)
Explosion Limits, Lower:Not available.
Upper: Not available.
NFPA Rating:
(estimated) Health: 1; Flammability: 1; Instability: 1
|
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. Avoid generating dusty conditions. Provide ventilation.
|
Section 7 - Handling and Storage
|
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
|
Engineering Controls:
