Section 5 - Fire Fighting Measures
Extinguishing Media Water spray, dry chemical, or carbon dioxide.
Specific Hazards when Fire-fight Burning may produce carbon monoxide, or carbon dioxide.
Specific Fire-fighting Procedure
In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing
apparatus with full face piece operated in the pressure demand or other positive pressure mode.
Specific Protection of FirefightersAs in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH and full protective gear
Section 6 - Accidental Release Measures
Personal Precautions
1. Wear appropriate personal protective equipment as specified in Section 8.
2. Keep unnecessary and unprotected personnel from entering.
3. Do not inhale the dust.
4. Restrict access to area until completion of clean up.
5. Minimize dust generation and accumulation.
6. Well ventilate the area.
Environmental Precautions
1. Remove all sources of ignition.
2. Ventilate area of leak or spill.
Methods for Cleaning up
Clean up spills in a manner that does not disperse dust into the air. Use non-sparking tools
and equipment. Pick up spill for recovery or disposal and place in a closed container.
Remove unnecessary people. If material comes in contact with water, neutralize liquid with
alkaline material (soda ash, lime), then absorb with an inert material (e.g. vermiculite, dry
sand, earth) and place in a chemical waste container. Do not use combustible materials, such
as saw dust. Do not flush to sewer.

Section 7 - Handling and Storage
Handling
1. Protect against physical damage.
2. Keep the container closed while not use.
3. Well ventilation.
4. No specific temperature requirement for the storage area.
Storage
1. Keep in a tightly closed container, store in a cool, dry, ventilated area away from sources
of heat, moisture and incompatibilities.
2. Containers of this material may be hazardous when empty since they retain product
residues (vapors, liquid);observe all warnings and precautions listed for the product.
Section 8 - Exposure Controls & Personal Protection
Engineering measures
1. Facilities storing or utilizing this material should be equipped with an eyewash facility
and a safety shower.
2. Use adequate general or local exhaust ventilation to keep airborne concentrations below
the permissible exposure limits.

Section 11 - Toxicological Information
Route of exposureEyeSkinIngestionInhalation
Symptomssore throat, coughing, respiratory distress, headache, nausea and irritation.
Immediate Toxicity
Skin:
1. 5~10% solution causes moderate skin irritation and possible corrodes.
2. An excess of Oxalic Acid can change the skin color and change the fingernail
become blue.
Eyes: May cause severe eye irritation. May result in corneal injury.
Inhalation:
1. Causes respiratory tract irritation.
2. It may also affect behavior/central nervous system (nausea and headache)
Ingestion:
1. May be harmful if swallowed.
2. 10% solution or solid causes gastrointestinal irritation
3. A less of oxalic acid causes headache and spasm; a lot of oxalic acid causes
weakness, arrhythmia and low blood pressure; an excess of oxalic acid causes
spasm and coma, even death

Bioaccumulative potentialOxalic acid is naturally contained as the potassium or calcium salt in
plants, vegetables, human urine, animal urine, and kidney stones. It is also the product of the
metabolism of many molds. Oxalic acid may be released to the environment in tobacco smoke,
automobile exhaust, rendering, in waste streams from pulp bleaching, and by photochemical
oxidations of anthropogenic compounds during long range transport.
Mobility in soilAn estimated Koc value of 5 for oxalic acid indicates high mobility in soil.
If released to soil, oxalic acid under environmental conditions (pH 5-9) will be in the form of the
oxalate ion (pKa1 and pKa2 of 1.25 and 4.28, respectively) and is expected to leach in soil.
Photolysis is expected to be an important fate process; the daytime persistence of oxalic acid on
soil surfaces is not expected to exceed a few hours. Based upon screening biodegradation tests,
biodegradation in soil is expected to be important.
Other adverse effectsIf released to water, oxalic acid will not volatilize, adsorb to sediment,
bioconcentrate in aquatic organisms, oxidize or hydrolyze. The predominant aquatic fate processes
are expected to be photolysis in surface waters and aerobic and anaerobic biodegradation. If
released to the atmosphere, removal from air via wet deposition, dry deposition, and photolysis is
likely to occur. Exposure of the general population to oxalic acid is expected to occur through
consumption of foods in which it is naturally contained, inhalation of contaminated air, and
consumption of contaminated groundwater. In occupational settings, exposure to oxalic acid may
occur through inhalation of vapors and through eye and skin contact.
