EMERGENCY OVERVIEW
Appearance: off-white powder.
Warning! Causes eye, skin, and respiratory tract
irritation. Contact with acids liberates toxic gas. Decomposed even
by weak acids, evolving hydrogen sulfide, H2S, a flammable, poisonous
gas with the odor of rotten eggs.
Target Organs: Respiratory system, eyes, skin.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation.
Ingestion:
Contact with stomach acid may liberate toxic hydrogen sulfide gas.
Inhalation:
Causes respiratory tract irritation.
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. Get medical aid immediately.
Skin:
Get medical aid immediately. Flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Ingestion:
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Never give anything by mouth to an unconscious person. Get medical
aid.
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.

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. Avoid contact with eyes, skin, and clothing. Avoid
ingestion and inhalation. Use only with adequate ventilation. Inform
laundry personnel of contaminant's hazards. Acids should not be used
around this material unless absolutely necessary and then only after
careful planning. Contact with acids liberates toxic gas.
Storage:
Keep container closed when not in use. Store in a cool, dry,
well-ventilated area away from incompatible substances. Keep away
from strong acids. 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
ventilation to keep airborne concentrations low.
