Unconscious: maintain adequate airway and respiration. Respiratory arrest: artificial respiration or oxygen. Cardiac arrest: perform resuscitation. Victim conscious with labored breathing: half-seated. Victim in shock: on his back with legs slightly raised. Vomiting: prevent asphyxia/aspiration pneumonia. Prevent cooling by covering the victim (no warming up). Keep watching the victim. Give psychological aid. Keep the victim calm, avoid physical strain. Depending on the victim's condition: doctor/hospital. First-aid measures after inhalation : Remove the victim into fresh air.

5 Respiratory problems: consult a doctor/medical service. First-aid measures after skin contact : Wash immediately with lots of water. Do not apply (chemical) neutralizing agents. Take victim to a doctor if irritation persists. First-aid measures after eye contact : Rinse immediately with plenty of water. Do not apply neutralizing agents. Take victim to an ophthalmologist if irritation persists. First-aid measures after ingestion : Rinse mouth with water. Immediately after ingestion: give lots of water to drink. Do not induce vomiting. Call Poison Information Centre ( ). Consult a doctor/medical service if you feel unwell. Ingestion of large quantities: immediately to hospital. Doctor: administration of chemical antidote. Doctor: gastric lavage is not recommended. Most important symptoms and effects (acute and delayed) Symptoms/effects after inhalation : AFTER INHALATION OF DUST: Dry/sore throat.

ON CONTINUOUS EXPOSURE/CONTACT: Corrosion of the eye tissue. Permanent eye damage. Symptoms/effects after ingestion : AFTER ABSORPTION OF LARGE QUANTITIES: Burns to the gastric/intestinal mucosa. Nausea. Blood in vomit. Blood in stool. Shock. FOLLOWING SYMPTOMS MAY APPEAR LATER: Decreased renal function. Change in urine output. Change in urine composition. Chronic symptoms : ON CONTINUOUS/REPEATED EXPOSURE/CONTACT: Decreased renal function. Irritation of the respiratory tract.

7 Irritation of the nasal mucous membranes. Coughing. Skin rash/inflammation. Immediate medical attention and special treatment, if necessary No additional information available SECTION 5: Fire-fighting measures Suitable (and unsuitable) extinguishing media Suitable extinguishing media : Preferably: water spray. Polyvalent foam. Alcohol-resistant foam. ABC powder. Carbon dioxide. Unsuitable extinguishing media : No unsuitable extinguishing media known. Specific hazards arising from the chemical Fire hazard : DIRECT FIRE HAZARD. Non-flammable. In finely divided state: increased fire hazard. INDIRECT FIRE HAZARD. Heating increases the fire hazard. Reactions involving a fire hazard: see "Reactivity Hazard". Oxalic acid , Dihydrate Safety Data Sheet according to Federal Register / Vol. 77, No. 58 / Monday, March 26, 2012 / Rules and Regulations 01/16/2018 EN (English US) 3/8 Explosion hazard : DIRECT EXPLOSION HAZARD.

8 Fine dust is explosive with air. INDIRECT EXPLOSION HAZARD. Dust cloud can be ignited by a spark. Reactions with explosion hazards: see "Reactivity Hazard". Reactivity : On heating: release of corrosive gases/vapours (formic acid ). Upon combustion: CO and CO2 are formed. Reacts violently with (strong) oxidizers: (increased) risk of fire/explosion. Reacts violently with (some) bases: release of heat. Decomposes on exposure to UV light: release of corrosive gases/vapours (formic acid ). Special protective equipment and precautions for fire-fighters Precautionary measures fire : Exposure to fire/heat: keep upwind. Exposure to fire/heat: consider evacuation. Exposure to fire/heat: have neighbourhood close doors and windows. Firefighting instructions : Cool tanks/drums with water spray/remove them into safety.

9 Dilute toxic gases with water spray. Protection during firefighting : Heat/fire exposure: compressed air/oxygen apparatus. SECTION 6: Accidental release measures Personal precautions, protective equipment and emergency procedures For non-emergency personnel Protective equipment : Gloves. Face-shield. Protective clothing. Dust cloud production: compressed air/oxygen apparatus. Dust cloud production: dust-tight suit. See "Material-Handling" to select protective clothing. Emergency procedures : Mark the danger area. Prevent dust cloud formation, by wetting. No naked flames. Wash contaminated clothes. In case of hazardous reactions: keep upwind. In case of reactivity hazard: consider evacuation. Measures in case of dust release : In case of dust production: keep upwind. Dust production: have neighbourhood close doors and windows.

10 In case of dust production: stop engines and no smoking. In case of dust production: no naked flames or sparks. Dust: spark-/explosionproof appliances/lighting equipment. For emergency responders Protective equipment : Equip cleanup crew with proper protection. Emergency procedures : Ventilate area. Stop release. Environmental precautions Prevent entry to sewers and public waters. Methods and material for containment and cleaning up For containment : Contain released substance, pump into suitable containers. Consult "Material-handling" to select material of containers. Plug the leak, cut off the supply. Knock down/dilute dust cloud with water spray. Powdered form: no compressed air for pumping over spills. Methods for cleaning up : Stop dust cloud by humidifying. Neutralize spill with quicklime or soda ash.
