**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful by inhalation, in contact with skin and if swallowed. Causes
severe burns. Possible risk of harm to the unborn child.
Potential Health Effects
Eye:
Causes eye burns. May result in corneal injury. Causes redness
and pain.
Skin:
Harmful if absorbed through the skin. Causes severe skin irritation
and possible burns. Rare chemical burns may occur from oxalic acid
and may cause hypocalcemia. Gangrene has occurred in the hands of
people working with oxalic acid solutions without rubber gloves. The
skin lesions are characterized by cracking of the skin and the
development of slow-healing ulcers. The skin may be bluish in color,
and the nails brittle and yellow.
Ingestion:
Causes gastrointestinal tract burns. Oxalic acid is toxic because of
its acidic and chelating properties. It is especially toxic when
ingested. As little as 5 grams (71 mg/kg) may be fatal. 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.
Oxalic acid can bind calcium to form calcium oxalate which is
insoluble at physiological pH. Calcium oxalate thus formed might
precipitate in the kidney tubules and the brain. Hypocalcemia
secondary to calcium oxalate formation might disturb the function of
the heart and nerves.
Inhalation:
Causes chemical burns to the respiratory tract. 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
at least 15 minutes. Get medical aid immediately.
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 alcohol-resistant
foam.
**** 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 runoff into storm sewers and ditches which lead to
waterways. 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. Minimize dust generation and
accumulation. Do not get in eyes, on skin, or on clothing. Do not
ingest or inhale. Discard contaminated shoes. Use only with adequate
ventilation.
Storage:
Keep container closed when not in use. Store in a cool, dry,
well-ventilated area away from incompatible substances.
**** 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 general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
