Material Safety Data SheetOxalic acid Section 1 - Chemical NameChemicals English name: ethanedioic acidTechnical Manual Code:CAS No .: 144-62-7Molecular formula: C 2 H 2 O 4Molecular Weight: 90.04Section 2 - Composition, Information on Ingredients Chemical Name Cas NoPercentOxalic acid144-62-7Section 3 - Hazards Risk category:Pathways: Skin and eye contact, inhalation.Health hazards: This product has a strong irritant and corrosive. Its dust or concentrated solutions can cause severe damage to the skin, eyes or mucous membranes. Oral corrosion mouth and digestive tract, gastrointestinal reactions, collapse, convulsions, shock and cause death, the apparent kidney damage and even uremia. Hypocalcemia may occur in the body with calcium ions. Long-term inhalation of vapors cause neurasthenia syndrome, headache, vomiting, nasal ulcers, protein, anemia appear in the urine.Environmental hazards:Explosion hazard:Section 4 - First Aid Measures Skin contact: Immediately remove contaminated clothing, rinse for at least 15 minutes with plenty of water. Medical treatment.Eye contact: immediately filed eyelid, with plenty of water or saline thoroughly washed at least 15 minutes. Medical treatment.Inhalation: rapidly from the scene to fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing has stopped, perform artificial respiration. Medical treatment.Ingestion: as soon as possible with water or water plus calcium lactate, calcium gluconate or lime gastric lavage. 40g glucose and then poured into the stomach. Section 5 - Fire Fighting Measures Hazardous characteristics: case of fire, combustible high fever. The thermal decomposition of toxic gasesHazardous combustion products:Fire fighting methods: firefighters are required to wear gas masks, at a safe distance, the wind on fire. Extinguishing Media: Water spray, foam, dry powder, carbon dioxide, sand.Section 6 - Spill responseEmergency treatment: Isolation leak contaminated areas, restricting access. Recommended emergency personnel wearing a dust mask (full cover), wear protective clothing. To avoid dust, carefully scan, bag placed transfer to a safe place. If large spills, plastic sheeting, canvas cover. Recycling or transported to the waste disposal sites. Section 7 - Handling and Storage Handling Precautions: isolation leak contaminated areas, restricting access. Cut off the fire source. Recommended emergency personnel wearing a dust mask (full cover), wear protective clothing. To avoid dust, carefully scan, bag placed transfer to a safe place. You can also rinse with plenty of water, wash water diluted into the wastewater system. If large spills, plastic sheeting, canvas cover. Recycling or shipped to the waste disposal sites.Storage: Store in a cool, dry, well-ventilated warehouse. Away from fire and heat. Keep container closed. With alkali, alkali metals, food chemicals stored separately, avoid mixing reservoir. Corresponding with the variety and quantity of fire equipment. Storage areas should be equipped with suitable material spill. Section 8 - Exposure Controls, Personal Protection Occupational Exposure LimitsChina MAC (mg / m3): not establishedFormer Soviet Union MAC (mg / m3): not establishedTLVTN: not establishedTLVWN: not establishedMonitoring methods: acid-base titrationEngineering controls: closed operation, local exhaust ventilation. Provide safety shower and eyewash equipment.Respiratory protection: its possible exposure to dust, wear a dust mask (full cover). Emergency rescue or evacuation, air respirator should be worn.Eye protection: Respiratory Protection has been protective.Physical protection: wear a jumpsuit type 52,400.Hand protection: Wear rubber gloves.Other protection: After work, take a shower. Attention to personal hygiene.
