Section 3 - Hazards Identification

EMERGENCY OVERVIEW
Appearance: white crystals.
Warning! Harmful if swallowed. Causes eye, skin,
and respiratory tract irritation. Harmful if absorbed through the
skin. May cause kidney damage. Hygroscopic (absorbs moisture from the
air).
Target Organs: Kidneys, heart, eyes, skin,
brain, nerves, mucous membranes.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Harmful if absorbed through the skin. Oxalate is an irritant and may
cause dermatitis. Skin lesions begin with epithelial cracking and the
formation of slow-healing ulcers. The fingers may appear cyanotic.
Ingestion:
Ulcerations of the mouth, vomiting of blood, and rapid appearance of
shock, convulsions, twitching, tetany, and cardiovascular collapse
may occur following ingestion of oxalic acid or its soluble salts.
Systemic effects may be due to formation of calcium oxalate which is
insoluble at physiological pH and can be deposited in the brain and
kidney tubules. Resultant hypocalcemia might disturb the function of
the heart and nerves. Mean lethal dose for oxalates in adults is
estimated at 10 - 30 grams (143 - 428 mg/kg).
Inhalation:
Inhalation of oxalic acid dust or vapor produces irritation of the
respiratory tract, protein in the urine, nosebleed, ulceration of the
mucous membranes, headache, nervousness, cough, vomiting, emaciation,
back pain (due to kidney injury), and weakness.
Chronic:
Inhalation of oxalic acid dust or mist over a long period of time
might result in weight loss and respiratory tract inflammation. Rats
administered oxalic acid at 2.5 and 5% in the diet for 70 days
developed depressed thyroid function and weight loss. A study of
railroad car cleaners in Norway who were heavily exposed to oxalic
acid solutions and vapors revealed a 53% prevalence of urolithiasis
(the formation of urinary stones), compared to a rate of 12% among
unexposed workers from the same company.

Section 4 - First Aid Measures
|
Eyes:
In case of contact, immediately flush eyes with plenty of water for a
t least 15 minutes. Get medical aid.
Skin:
In case of contact, immediately flush skin with plenty of water for
at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. Wash clothing before reuse.
Ingestion:
If swallowed, do NOT induce vomiting. Get medical aid immediately.
If victim is fully conscious, give a cupful of water. Never give
anything by mouth to an unconscious person.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
Antidote:
Intravenous administration of calcium gluconate or calcium chloride
may be required if hypocalcemia or hypocalcemic tetany occur.
|
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. Use water
spray to keep fire-exposed containers cool.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or appropriate foam.

Upper: Not available.
NFPA Rating:
(estimated) Health: 2; Flammability: 1; Instability: 0
|
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. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation.
|
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Minimize dust
generation and accumulation. Avoid contact with eyes, skin, and
clothing. Keep container tightly closed. Avoid breathing dust.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Store
protected from moisture. Oxalates slowly corrode steel.
|
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.
