Appearance: Colorless to pale yellow liquid with an ammonia-like odor
Molecular Formula: C4H13N3
Molecular Weight: 103.17 g/mol
Major Risks: Causes severe skin burns and eye damage, respiratory tract irritation, harmful if swallowed
GHS Classification: Skin Corrosion (Category 1B), Acute Toxicity Oral (Category 4), Eye Damage (Category 1)
Pictograms and Signal Word: Corrosive symbol, “Danger”
Routes of Exposure: Skin contact, eye contact, inhalation, ingestion
Important Symptoms: Burning, redness, pain, vision loss on contact with eyes, coughing, sore throat, breathing difficulty if inhaled, abdominal pain if swallowed
Main Ingredient: Diethylenetriamine
Concentration: Typically >99% for industrial chemical
Impurities: Low levels of water, minor amines may be present depending on the source
Inhalation: Move the person to fresh air, seek immediate medical advice if breathing issues continue
Skin Contact: Remove contaminated clothing, rinse skin thoroughly with water for at least 15 minutes, seek medical attention for burns
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present, continue rinsing, urgent medical attention required
Ingestion: Rinse mouth, do not induce vomiting, give water if the person is alert, seek medical help
Sensitivity: Flammable liquid and vapor
Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide
Hazardous Products of Combustion: Nitrogen oxides, carbon oxides, ammonia
Advice for Firefighters: Use self-contained breathing apparatus, keep upwind, avoid inhaling fumes
Special Hazards: Containers can explode due to heat, runoff may cause environmental risk
Personal Protection: Wear rubber gloves, goggles, chemical-resistant apron, face shield
Initial Actions: Evacuate area, ventilate, eliminate ignition sources
Cleanup: Absorb with sand or inert material, collect in suitable containers for disposal
Do Not: Use sawdust or combustible absorbents, allow to enter drains or watercourses
Spill Size: Large spills require emergency response, small spills call for thorough surface cleaning
Handling: Only handle with adequate ventilation, prevent skin and eye contact, avoid inhaling vapors
Storage: Keep in tightly closed containers, store in a cool, dry, well-ventilated spot
Keep Away From: Acids, oxidizers, halogenated compounds, open flames, sparks
Other Precautions: Inspect containers regularly for leaks, segregate from incompatible substances, check for corrosion as it can degrade some steel types
Engineering Controls: Use local exhaust, eyewash stations, and safety showers
Workplace Exposure Limit (OSHA PEL): 1 ppm, 4.2 mg/m3 (8-hour TWA)
PPE for Routine Use: Chemical-resistant gloves, goggles, lab coat or overalls, appropriate footwear
Respiratory Protection: Use approved respirators if ventilation falls short
Hygiene Measures: Wash hands and face after handling, prohibit eating and drinking around the work area
Physical State: Liquid
Color: Ranges from colorless to pale yellow
Odor: Strong ammonia smell
Boiling Point: 207°C
Melting Point: -39.6°C
Flash Point: 94°C (open cup)
Auto-Ignition Temperature: 385°C
Vapor Pressure: Low at room temperature
Solubility: Miscible with water
Density: 0.954 g/cm3 at 20°C
pH: Strongly basic
Chemical Stability: Stays stable under ordinary conditions
Possible Reactions: Reacts violently with acids, strong oxidizers, halogenated hydrocarbons
Hazardous Polymerization: No significant risk
Decomposition Products: Releases toxic gases like nitrogen oxides and ammonia on decomposition
Conditions to Avoid: Heating, contact with acids or oxidants, exposure to air or moisture over long periods may degrade product
Acute Toxicity: Oral LD50 (rat) around 1,080 mg/kg, can be fatal in large amounts
Routes of Exposure: Absorption from skin, inhalation, ingestion
Irritation and Corrosivity: Damages skin, eyes, mucous membranes
Sensitization Potential: Can cause allergic reactions or asthma-like symptoms on repeated exposure
Chronic Health Effects: May cause liver and kidney injury after prolonged exposure; some evidence links chronic inhalation to respiratory issues
Symptom Details: Burning pain, cough, chest tightness, long-term exposure may lead to dermatitis
Toxicity to Aquatic Life: Harmful to fish, invertebrates, and algae
Environmental Fate: Degrades relatively slowly in water, mobility is high due to water solubility
Bioaccumulation: Not likely in animal tissues, but still presents ecological risks if released
Persistence: May persist and contribute to eutrophication if discharged in large amounts
Recommendations: Prevent spills into soil, surface waters, or sewers
Preferred Disposal: Incineration at approved hazardous waste facility
Avoid: Dumping in regular trash or drains
Containers: Triple-rinse before recycling or discarding; treat rinsate as hazardous
Local Laws: Abide by federal and local environmental rules, consult with waste contractor for proper handling
Cleanup Waste: Mix with compatible combustibles for incineration if possible
