Eye Contact: Rinse cautiously with water for at least 15 minutes, hold eyelids open; seek immediate medical advice—contact lenses must be removed if present and easy
Skin Contact: Take off contaminated clothing, rinse skin thoroughly with water, wash with soap and water for at least 15 minutes, get medical help if irritation or symptoms persist
Inhalation: Move exposed person to fresh air without delay, keep warm and at rest; immediate medical attention is critical if symptoms show
Ingestion: Rinse mouth with water, never give anything by mouth to an unconscious person, do not induce vomiting, seek emergency medical attention

Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam
Unsuitable Media: Water jets may spread chemical
Special Hazards: Hazardous gases such as nitrogen oxides and toxic vapor can form under fire conditions
Protective Equipment: Full protective clothing with self-contained breathing apparatus
Precautions: Move containers from fire area if safe, prevent runoff from entering drains; stay upwind of the fire, avoid exposure to vapors/fumes
Personal Precautions: Ventilate area, evacuate unnecessary personnel, use personal protective equipment (gloves, protective suit, goggles)
Environmental Precautions: Prevent entry into sewers, surface water, or soil—contain spill with inert materials like sand
Spill Cleanup Methods: Absorb with inert material, sweep up, transfer to properly labeled chemical waste containers; flush area with lots of water to prevent residue build-up
Reference to Other Sections: For exposure controls and personal protection, see section 8
Safe Handling: Avoid breathing vapor/mist; avoid skin and eye contact, make sure local exhaust ventilation works effectively, wash hands after handling
Storage Conditions: Store in tightly closed containers in a cool, dry, well-ventilated area; keep out of direct sunlight, segregate from strong acids, oxidizers
Incompatible Materials: Strong oxidizers, mineral acids, water-reactive materials
Storage Stability: Protect from freezing and moisture, keep away from food and drink containers
Control Parameters: No established occupational exposure limits for Dimethyltetradecyl Tertiary Amine, keep exposure at lowest achievable levels using best practices
Engineering Controls: Use local exhaust ventilation/closed systems; keep eyewash and safety shower accessible
Personal Protective Equipment: Nitrile or neoprene gloves, splash-proof goggles, chemical-resistant apron/overall, approved respiratory protection for higher concentrations
Hygiene Measures: Remove contaminated clothes immediately, wash before reuse, do not eat, drink or smoke in work area, wash hands and face thoroughly after handling

Acute Toxicity: Oral LD50 (rat): ~1200 mg/kg; skin LD50: severe irritation and burns possible at high concentrations
Irritation: Strong skin and eye irritant; causes burns, possible permanent eye damage with direct contact
Sensitization: No confirmed reports of respiratory or skin sensitization in humans
Chronic Exposure: Prolonged contact leads to dermatitis, chemical burns, respiratory distress
Carcinogenicity: No evidence of carcinogenic potential in data reviewed
Mutagenicity: Not classified as mutagenic
Other Effects: May aggravate pre-existing skin or respiratory conditions
Aquatic Toxicity: Highly toxic to fish and aquatic invertebrates; LC50 (fish, 96h): 1–10 mg/L
Persistence and Degradability: Not readily biodegradable, long-lasting impacts in aquatic environments
Bioaccumulation: Strong tendency for bioaccumulation due to high partition coefficient
Mobility in Soil: Low to moderate, risk of migration to groundwater if released
Other Adverse Effects: Alters water chemistry, potential to disrupt aquatic food chains
Waste Disposal Methods: Dispose of contents and containers through licensed hazardous waste contractor, follow local and national regulations for incineration or chemical treatment
