Inhalation: Move affected person into fresh air promptly, assist breathing if necessary, seek medical attention for persistent symptoms
Skin Contact: Remove contaminated clothing, flush skin for at least 15 minutes with running water, seek medical aid if irritation or burns develop
Eye Contact: Rinse cautiously with water for at least 20 minutes, remove contact lenses if present, get immediate medical help
Ingestion: Do not induce vomiting, rinse mouth, give water to drink if conscious, call poison center or physician right away
Most Important Symptoms: Severe burning of mucous membranes, shock, breathing difficulty from ingestion or inhalation
Suitable Extinguishing Media: Foam, dry chemical, CO2, water spray
Unsuitable Extinguishing Media: Direct high pressure water jet (may spread the chemical)
Specific Hazards: Generates toxic fumes (hydrogen chloride, nitrogen oxides) under fire conditions, containers may explode from pressure build-up
Protective Equipment: Full protective gear including self-contained breathing apparatus
Special Procedures: Move containers from fire area if safe, control contaminated run-off, use water spray to cool containers and exposed personnel
Personal Precautions: Wear appropriate PPE including gloves, eye protection, respirator
Evacuation: Isolate area, prevent unprotected persons from entering
Spill Cleanup: Contain with inert absorbent (sand, earth), scoop up and place in labeled containers, avoid raising dust
Environmental Precautions: Prevent release to soil, waterways, drains, use booms or barriers if necessary, notify authorities if large spill threatens environment
Decontamination: Wash area with copious water once bulk removed, ventilate site
Safe Handling: Wear chemical-resistant gloves, eye/face protection, avoid direct contact, wash thoroughly after handling, use in well-ventilated area
Storage Conditions: Store cool, dry, well-ventilated, away from acids, oxidizers, and food, keep containers tightly closed and upright, avoid freezing
Incompatible Materials: Strong oxidizers, acids, anionic surfactants (loss of effectiveness and hazardous reactions)
Hygiene Practices: No eating, drinking or smoking during use, wash hands before breaks and after work
Other Precautions: Keep out of reach of children and unauthorized persons
Occupational Exposure Limits: No OSHA or ACGIH limits specifically established for this compound; keep exposure to lowest feasible levels
Engineering Controls: Provide local exhaust ventilation, safety showers, eye wash stations
Personal Protective Equipment: Chemical splash goggles, face shield, gloves made of nitrile or neoprene, long-sleeved clothing
Respiratory Protection: Use NIOSH-approved respirator for nuisance vapor or mist, especially in enclosed or poorly ventilated areas
Environmental Controls: Prevent concentration in air from exceeding safe levels, use closed systems or ensure process enclosure
Appearance: Clear to straw-colored liquid
Odor: Mild, aromatic or amine-like odor
pH: (Depending on concentration) Typically 6-8 for diluted solutions
Melting Point/Freezing Point: Below 0°C (dilute solutions), not determined for concentrated material
Boiling Point: Above 100°C
Flash Point: Not flammable under normal conditions
Solubility: Readily soluble in water
Vapor Density (Air=1): Not available
Density/Specific Gravity: 0.96 – 1.01 g/cm³ (for commercial solutions)
Partition Coefficient (n-octanol/water): Not available
Decomposition Temperature: Elevated temperatures produce toxic gases
Viscosity: Low to moderate (solution-dependent)
Chemical Stability: Stable under normal storage and handling conditions
Hazardous Reactions: Reacts with strong oxidizing agents, reaction with anionics leads to precipitation and loss of efficiency
Decomposition Products: Hydrogen chloride, benzene, nitrogen oxides on burning or decomposition
Conditions to Avoid: Avoid excessive heat, mixing with reactive chemicals, direct sunlight for long periods
Polymerization: Will not occur under recommended conditions
Acute Toxicity: Oral LD50 (rat): 200-500 mg/kg (may vary by study); can be fatal if swallowed in concentrated form
Skin Corrosion/Irritation: Causes severe burns, redness, ulceration following prolonged contact
Serious Eye Damage/Irritation: Causes serious, potentially irreversible eye injury
Respiratory Sensitization: Can cause irritation to respiratory system
Long-term Exposure: No evidence of carcinogenicity or teratogenicity in available studies, may cause dermatitis with repeated exposure
Other Effects: Symptoms include cough, shortness of breath, sore throat, stomach discomfort, or systemic toxicity after significant ingestion or absorption
Aquatic Toxicity: Very toxic to aquatic life, LC50 (fish, 96hr): 0.5–2.0 mg/L range (depending on species and formulation)
Persistence and Degradability: Moderately persistent, breaks down slowly in soil and water, some potential for bioaccumulation in aquatic organisms has been noted
Bioaccumulation: Possible in aquatic species, but unlikely at environmental concentrations from normal use
Mobility in Soil: Moves with water, binds weakly to sediments
Other Adverse Effects: Avoid direct discharges to lakes, streams, or municipal sewers
Waste Treatment Methods: Small quantities can be diluted and flushed with plenty of water if permitted by law, otherwise, take to a licensed chemical disposal facility
Hazardous Waste Number: Classified as hazardous waste in many jurisdictions due to toxicity
Container Disposal: Triple rinse containers, offer for recycling or dispose at approved facility
