Chemical Name: Ethylenediaminetetraacetic Acid Disodium Salt Dihydrate
Concentration: Over 98% by weight
CAS Number: 6381-92-6
Impurities and Stabilizing Additives: Less than 2% water, minimal trace impurities
General Advice: Move away from exposure area to fresh air or safe environment. Immediately remove contaminated clothing.
Inhalation: Move person to fresh air. Seek medical attention for symptoms like shortness of breath or coughing.
Skin Contact: Wash thoroughly with soap and plenty of water. Remove contaminated clothes and shoes. Get medical attention if irritation continues.
Eye Contact: Rinse cautiously with water for at least 15 minutes. Remove contact lenses. Do not rub eyes. Seek medical advice.
Ingestion: Rinse mouth with water without inducing vomiting unless instructed by medical personnel. Seek medical assessment for nausea or discomfort.
Most Important Symptoms and Effects, Both Acute and Delayed: Eye, skin, and respiratory tract irritation; nausea after ingestion; potential for delayed allergic reaction in sensitive individuals.
Notes to Physician: Treat symptomatically and supportively.
Suitable Extinguishing Media: Use water spray, dry chemical, foam, or carbon dioxide. Avoid high-pressure jet streams that may spread dust.
Special Hazards Arising from Chemical: Emits toxic fumes of nitrogen oxides (NOx), carbon monoxide, and carbon dioxide when heated above decomposition.
Advice for Firefighters: Wear self-contained breathing apparatus and full protective gear. Stay upwind and keep unwanted personnel from the area.
Fire and Explosion Hazards: Powdered or granular material may form combustible dust clouds in air under particular conditions, posing explosion risk. Take precautions to minimize dust generation.
Personal Precautions: Wear gloves, goggles, and dust mask. Prevent further release and avoid breathing dust.
Environmental Precautions: Keep out of drains, water courses, and soil. Prevent entry into sewers and natural waterways.
Cleanup Methods: Sweep up gently to minimize dust, collect in closed containers for disposal. Wash spill site with soap and water after material pickup.
Other Recommendations: Ensure adequate ventilation during cleanup. Dispose of all cleanup materials in accordance with local and national regulations.
Handling: Work in well-ventilated area. Avoid creating dust. Use proper personal protective equipment including gloves and protective eyewear. Prevent contact with skin and eyes.
Storage: Store in tightly closed containers away from moisture, heat, and incompatible materials such as strong acids, oxidizers, and foodstuffs. Keep in a dry, cool, well-ventilated area, and segregate from edible materials.
Specific Storage Requirements: Label container clearly. Check regularly for leaks or damage. Place material away from sources of ignition and direct sunlight.
Exposure Limits: No established occupational exposure limits for this compound from OSHA or ACGIH, but control dust as for nuisance particulates.
Engineering Controls: Use local exhaust ventilation or process enclosure to minimize airborne exposure. Implement dust control measures.
Personal Protective Equipment: Chemical-resistant gloves, goggles, lab coat, and dust mask or respirator (NIOSH-approved) for dusty operations.
Hygiene Measures: Wash hands thoroughly after handling the chemical, before eating, drinking, or using restrooms. Keep work clothes separate from regular garments. Shower after extended exposure.
Environmental Controls: Prevent release to the environment. Ensure procedures for decontamination and waste handling are enforced.

Explosive Properties: Dust can present explosion hazard if dispersed in air and ignited
Oxidizing Properties: Non-oxidizing
Chemical Stability: Stable under recommended storage conditions. Degrades slowly with prolonged exposure to moisture.
Reactivity: Reacts with strong acids, releasing toxic gases.
Possibility of Hazardous Reactions: Dust may form explosive atmospheres in confined spaces.
Conditions to Avoid: Elevated temperatures, contact with acids or strong oxidizing agents, exposure to moisture.
Incompatible Materials: Strong acids, strong oxidizers, reducing agents.
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, nitrogen oxides, disodium salts.
Routes of Exposure: Inhalation, ingestion, skin contact, eye contact.
Acute Toxicity: Oral LD50 (rat): Around 2000 mg/kg; inhalation and dermal toxicity data limited, generally low toxicity.
Skin Irritation: Causes moderate irritation, may cause redness or inflammation with sustained contact.
Eye Irritation: Strongly irritating; exposure can lead to watering, redness, blurred vision.
Chronic Effects: Prolonged or repeated exposure may cause dermatitis or allergic reactions.
