EMERGENCY OVERVIEW
Not available.
Potential Health Effects
Eye:
May cause mild eye irritation.
Skin:
May cause skin irritation.
Ingestion:
Causes gastrointestinal irritation with nausea, vomiting and
diarrhea.
Inhalation:
May cause respiratory tract irritation. Inhalation of fumes may
cause metal fume fever, which is characterized by flu-like symptoms
with metallic taste, fever, chills, cough, weakness, chest pain,
muscle pain and increased white blood cell count.
Chronic:
May cause kidney damage.
**** 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.
Skin:
Immediately 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:
Do not induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Get medical aid.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Do NOT use mouth-to-mouth
resuscitation.
Notes to Physician:
Antidote:
The use of calcium gluconate to precipitate the oxalate should be
determined by only qualified medical personnel.
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
Material will not burn. During a fire, irritating and highly toxic
gases may be generated by thermal decomposition or combustion. Use
water with caution and in flooding amounts.
Extinguishing Media:
Use extinguishing media most appropriate for the surrounding fire.
**** 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 or absorb material, then place into a
suitable clean, dry, closed container for disposal. Avoid generating
dusty conditions. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash hands before eating. Use with adequate ventilation. Minimize
dust generation and accumulation. Avoid contact with eyes, skin, and
clothing.
Storage:
Store in a cool, dry, well-ventilated area away from incompatible
substances. Keep away from water.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Good general ventilation should be sufficient to control airborne
levels. Facilities storing or utilizing this material should be
equipped with an eyewash facility and a safety shower.
Exposure Limits
