EMERGENCY OVERVIEW
Appearance: colorless crystalline powder.
Warning! Flammable solid. Causes respiratory tract
irritation. Causes eye and skin irritation. May cause digestive tract
irritation. Hygroscopic (absorbs moisture from the air). May cause
sensitization by inhalation and by skin contact.
Target Organs: Respiratory system, eyes, skin.
Potential Health Effects
Eye:
Causes eye irritation. Causes redness and pain.
Skin:
Causes skin irritation. May cause skin sensitization, an allergic
reaction, which becomes evident upon re-exposure to this material.
Causes redness and pain.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea.

No information found.
Section 4 - First Aid Measures
|
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid imme
diately.
Skin:
Get medical aid. Immediately flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Ingestion:
Do not induce vomiting. 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 immediately.
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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Containers
may explode in the heat of a fire. Dust can be an explosion hazard
when exposed to heat or flame. Flammable solid. May re-ignite after
fire is extinguished. May be ignited by friction, heat, sparks, or
flame.
Extinguishing Media:
Use water fog, dry chemical, carbon dioxide, or regular foam. Cool
containers with flooding quantities of water until well after fire is
out.
Flash Point: 482e deg F ( 250.00 deg C)
Autoignition Temperature: Not applicable.
Explosion Limits, Lower:Not available.
Upper: Not available.
NFPA Rating:
(estimated) Health: 2; Flammability: 2; Instability: 0
Section 6 - Accidental Release Measures
|
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
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. Remove all sources of
ignition. Use a spark-proof tool.
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Minimize dust generation and
accumulation. Avoid contact with eyes, skin, and clothing. Empty
containers retain product residue, (liquid and/or vapor), and can be
dangerous. Keep container tightly closed. Avoid ingestion and
inhalation. Use with adequate ventilation. Do not pressurize, cut,
weld, braze, solder, drill, grind, or expose empty containers to
heat, sparks or open flames.
Storage:
Keep away from heat, sparks, and flame. Store in a cool, dry place.
Keep container closed when not in use. Keep away from strong acids.

Section 8 - Exposure Controls, Personal Protection
|
Engineering Controls:
Use adequate general or local exhaust ventilation to keep airborne
concentrations below the permissible exposure limits.
