SECTION 4 - FIRE AND EXPLOSION DATA
NO YES
FLAMMABILITY IF YES, UNDER WHAT CONDITIONS?
May be combustible at high temperature - Slightly flammable to flammable in presence of heat. As with most organic
solids, fire is possible at elevated temperatures. Fine dust dispersed in air in sufficient concentrations, and in the
presences of an ignition source is a potential dust explosion hazard.
MEANS OF EXTINCTION
SMALL: Use DRY chemical powder.
LARGE: Use water spray, fog or foam. Do NOT use water jet.

NO YES
INCOMPATIBILITY WITH OTHER SUBSTANCES IF SO, WHICH ONES?
Reactive with oxidizing agents, metals, alkalis.
REACTIVITY, AND UNDER WHAT CONDITIONS
Incompatible with chlorites, hypochlorites, silver and silver compounds, furfural alcohol. Hygroscopic; keep container
tightly closed.

SECTION 6 - TOXICOLOGICAL PROPERTIES
ROUTE OF ENTRY
INGESTION
INHALATION
SKIN CONTACT SKIN ABSORPTION EYE CONTACT
EFFECTS OF ACUTE EXPOSURE TO PRODUCT
Very hazardous in case of skin contact (irritant), of eye contact (irritant), of ingestion, of inhalation. Hazardous in case of
skin contact (permeator), of eye contact (corrosive). Slightly hazardous in case of skin contact (corrosive). The amount
of tissue damage depends on length of contact. Eye contact can result in corneal damage or blindness. Skin contact can
produce inflammation and blistering. Inhalation of dust will produce irritation to gastro-intestinal or respiratory tract,
characterized by burning, sneezing and coughing. Severe over-exposure can produce lung damage, choking,
unconsciousness or death. Inflammation of the eye is characterized by redness, watering, and itching. Skin inflammation
is characterized by itching, scaling, reddening, or, occasionally, blistering.
Skin: Causes skin irritation. Rare chemical burns may occur. Harmful if absorbed through the skin. Eyes: Causes severe
eye irritation with possible burns. It may result in corneal damage and conjunctivitis. Inhalation: Causes irritation of the
respiratory tract, ulceration of the mucous membranes. Inhalation of oxalic acid may also cause digestive disturbances
such as nausea and vomiting as well as affecting the nerves and urinary system and causing headache, muscular
irritability, weakness, and albuminuria Ingestion: Harmful if swallowed. Causes severe digestive tract irritation and
possible burns. It may affect the cardiovascular system, and urinary system. Symptoms may include vomiting (often
bloody or with coffee-ground appearance), diarrhea, bloody stool, hypermotility, abdominal pain, intense burning pain in
the throat, esophagus, stomach, ulceration/burning of the mouth, esophagus, and stomach, severe purging, weak pulse,
hypotension, cardiac irregularities, cardiovascular collapse.
Other symptoms may include convulsions, headache, twitching, tetnay, stupor, coma, tingling of fingers and toes,
muscular irritability. Renal damage, as evidenced by oliguria, albuminuria, hematuria, may occur because Oxalic acid
can bind calcium to form calcium oxalate which is insoluble at physiological pH. The calcium oxalate formed might
precipitate in the kidney tubules. Hypocalcemia may also occur, which is what may affect the function of the heart and
nerves and cause the above cardiovascular and nervous system effects.
EFFECTS OF CHRONIC EXPOSURE TO PRODUCT
The substance may be toxic to kidneys, the nervous system, mucous membranes, heart, brain, skin, eyes. Repeated or
prolonged exposure to the substance can produce target organs damage. Repeated exposure of the eyes to a low level
of dust can produce eye irritation. Repeated skin exposure can produce local skin destruction, or dermatitis. Repeated
inhalation of dust can produce varying degree of respiratory irritation or lung damage. May cause adverse reproductive
effects based on animal test data. No human data found.
Skin: Prolonged or repeated exposure may cause localized pain and cyanosis of the fingers, and even gangrenous
changes. This has occurred on the hands of people working with oxalic acid solutions without rubber gloves. Ingestion
and Inhalation: Repeated or prolonged ingestion and inhalation may affect metabolism/appetite resulting in weight loss.
Inhalation of mist over a long period of time may result in respiratory tract inflammation. Ingestion of oxalic acid over a
long period of time may cause depressed thyroid function.

ENGINEERING CONTROLS (SPECIFY eg. VENTILATION, ENCLOSED PROCESS)
Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below
recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to
airborne contaminants below the exposure limit.
LEAK AND SPILL PROCEDURE
Use appropriate tools to put the spilled solid in a convenient waste disposal container. If necessary: Neutralize the
residue with a dilute solution of sodium carbonate.
WASTE DISPOSAL
According to local, provincial, and federal regulations.
HANDLING PROCEDURES AND EQUIPMENT
Keep container dry. Keep away from heat. Keep away from sources of ignition. Empty containers pose a fire risk,
evaporate the residue under a fume hood. Ground all equipment containing material. Do not ingest. Do not breathe dust.
Never add water to this product. In case of insufficient ventilation, wear suitable respiratory equipment. If ingested, seek
medical advice immediately and show the container or the label. Avoid contact with skin and eyes. Keep away from
incompatibles such as oxidizing agents, metals, alkalis.
STORAGE REQUIREMENTS
Keep container tightly closed. Keep container in a cool, dry, well-ventilated area. Container may be hazardous when
empty since they retain product residues (Dust, Solids) observe all warnings and precautions listed for the product

SECTION 8 - FIRST AID MEASURES
SPECIFIC MEASURES
In case of contact, immediately flush skin with plenty of water for at least 15 minutes while
SKIN
removing contaminated clothing and shoes. Cover the irritated skin with an emollient. Cold water
may be used. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical
attention immediately.
Eye Contact Check for and remove any contact lenses. In case of contact, immediately flush eyes
EYES
with plenty of water for at least 15 minutes. Cold water may be used. Get medical attention
immediately.
If inhaled remove to fresh air. If not breathing give artificial respiration. If breathing is difficult, give
INHALATION
oxygen. Get medical attention.
INGESTION Do NOT induce vomiting unless directed to do so by medical personnel. Never give anything by
mouth to an unconscious person. Loosen tight clothing such as collar, tie, belt or waistband. If
large quantities of this material are swallowed, call a physician immediately. Get medical attention if
symptoms appear.
IF IRRITATION PERSISTS AND IN ALL OTHER CASES, GET IMMEDIATE MEDICAL ATTENTION.
