Hazard Identification

Classification: Harmful if swallowed, irritant to eyes/skin/respiratory system
Hazard Statements: Causes skin and eye irritation, may harm if inhaled or ingested, presents acute health hazard upon overexposure
Precautionary Statements: Avoid ingestion, inhalation, and contact with eyes or skin; wear appropriate protective gear; keep out of reach of children; avoid environmental discharge

Composition / Information on Ingredients

Chemical Identity: Tetraethylammonium Iodide
Concentration: Typically 98–100% pure
Impurities: May carry trace amounts of basic salts or organic residues depending on supplier
Hazardous Components: None beyond main chemical identified; always verify with current lot-specific certificate of analysis

First Aid Measures

Inhalation: Remove affected individual to fresh air, seek medical attention if symptoms persist, do not use mouth-to-mouth
Skin Contact: Rinse immediately with soap and plenty of water, remove contaminated clothing, consult doctor if irritation develops
Eye Contact: Rinse eyes cautiously with water for several minutes, remove contact lenses if present, continue rinsing, consult physician promptly
Ingestion: Rinse mouth with water, do not induce vomiting without direction from medical professionals, seek emergency medical care
Most Important Symptoms: Eye redness, skin irritation, respiratory discomfort, nausea upon ingestion

Fire-Fighting Measures

Suitable Extinguishers: Carbon dioxide, dry chemical powder, foam, water spray
Unsuitable Extinguishers: Avoid high-pressure water jets which may spread product
Hazards From Combustion: Releases toxic fumes such as hydrogen iodide, nitrogen oxides, carbon oxides during fire
Protective Equipment: Firefighters wear self-contained breathing apparatus and chemical protective clothing
Other Advice: Remove containers from fire area if safe, use water to cool exposed containers, avoid run-off into water sources

Accidental Release Measures

Personal Precautions: Isolate unsafe area, ventilate space, always put on suitable gloves and goggles, avoid inhalation
Spill Cleanup: Collect with inert absorbent such as vermiculite, scoop into chemical waste container, wash spill area with plenty of water
Environmental Precautions: Prevent run-off into drains, soil, or water sources, notify environmental authorities if significant quantity spills
Disposal of Cleanup Materials: Seal contaminated material in tightly closed containers for waste collection
Decontamination: After cleanup, wash hands and exposed skin thoroughly

Handling and Storage

Handling Advice: Minimize dust formation, avoid all personal contact, only use under effective local exhaust ventilation, prevent static discharge during transferring, never eat or drink in handling areas
Storage Conditions: Keep in original tightly closed container, store in cool, dry, and well-ventilated area away from moisture and incompatible substances such as strong oxidizers
Incompatibilities: Strong acids, strong bases, strong oxidizers and reducing agents
Special Requirements: Use corrosion-resistant containers, label all containers clearly, keep away from children and unauthorized personnel

Exposure Controls / Personal Protection

Exposure Limits: No established exposure limits from OSHA, ACGIH or NIOSH, handle in accordance with good industrial hygiene practices
Engineering Controls: Use efficient local exhaust ventilation, keep eyewash stations and safety showers accessible
Personal Protective Equipment: Wear protective gloves (nitrile or latex), chemical splash goggles, laboratory coat or apron; avoid direct skin or eye contact at all times
Respiratory Protection: Wear approved respirator if risks of inhalation exist, especially in poorly ventilated spaces
Hygiene Measures: Wash hands before breaks and after work, do not smoke or eat in work area

Molecular Weight: 257.15 g/mol
Melting Point: Around 297–301°C
Boiling Point: Not applicable (decomposes upon heating)
Solubility: Soluble in water and polar organic solvents
Density: Approximately 1.37 g/cm³
pH (1% solution): Neutral to slightly alkaline
Vapor Pressure: Negligible at room temperature
Other Properties: Hygroscopic; absorbs moisture under ambient conditions

Stability and Reactivity

Chemical Stability: Stable under recommended conditions of use and storage
Reactivity: Can react with strong oxidizers, acids, and alkalis to generate hazardous products
Conditions to Avoid: Moisture, incompatible chemicals, high temperatures, poorly ventilated spaces
Hazardous Decomposition Products: Releases hydrogen iodide, nitrogen oxides, carbon monoxide and carbon dioxide upon decomposition
Polymerization: No hazardous polymerization expected under normal handling

Toxicological Information

Routes of Exposure: Inhalation, ingestion, skin and eye contact
Acute Toxicity: May be harmful if swallowed or inhaled; can cause irritation to mucous membranes, gastrointestinal tract, skin, or eyes
Symptoms: Redness and severe irritation to eyes, itching or rash on skin, coughing, sore throat, headache, stomach upset if ingested
Chronic Effects: No long-term carcinogenicity or mutagenicity studies available; repeated exposure can heighten risk of allergic skin reactions or respiratory effects
Specific Target Organ Toxicity: No conclusive data for TEA iodide, but similar quaternary ammonium compounds show low systemic toxicity in controlled settings

Ecological Information

Ecotoxicity: Data on aquatic or terrestrial toxicity is not established; avoid environmental discharge
Persistence and Degradability: Expected to have limited natural degradation; may persist under some conditions
Bioaccumulation: No evidence for significant potential, but safety requires collecting all wastes
Mobility in Soil: High solubility points toward mobility in ground water following release; keep containment secure
Other Concerns: Prevent rinsate and residues from entering soil, water bodies, or public sewer systems

Disposal Considerations

Waste Treatment: Incinerate under controlled conditions in compliance with national/local environmental regulations
Packing Waste: Use approved, chemically resistant containers for disposal
Waste Code (if applicable): Refer to local (state, federal) hazardous waste codes specific to quaternary ammonium salt disposal
Precautions: Do not mix with household or general waste streams; contain all waste securely for pick-up by licensed hazardous material handlers
Recycling/Re-use: Not recommended due to contamination risk; always err on the side of chemical disposal safety

Transport Information

UN Number: Not classified as a hazardous material for transport under ADR, IATA, or IMDG regulations
Shipping Name: Tetraethylammonium Iodide
Transport Hazard Class: Non-regulated
Packing Group: Non-regulated, ship in well-sealed packaging
Special Precautions for Transport: Store and ship upright, away from moisture or chemically incompatible substances, secure packaging to avoid breakage

Regulatory Information

Labeling: Signal word: Warning; hazard pictograms for acute toxicity and irritant
