General Advice: Move person to fresh air; avoid direct contact; ensure medical attention for all exposures
Inhalation: Remove from exposure; provide oxygen if breathing is difficult; seek immediate medical attention
Skin Contact: Remove contaminated clothing and shoes; wash with plenty of water and soap for at least 15 minutes; seek medical attention for irritation or burns
Eye Contact: Rinse cautiously with water for at least 15 minutes; remove contact lenses if present and easy to do; get prompt medical attention
Ingestion: Rinse mouth; do not induce vomiting; seek medical attention immediately
Most Important Symptoms: Severe burns, blisters, pain, possible respiratory distress
Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide (CO2)
Unsuitable Media: Direct water jet may cause frothing and spread the product
Specific Hazards: Combustion produces hazardous gases such as nitrogen oxides (NOx), carbon oxides, and ammonia fumes
Protective Equipment: Wear self-contained breathing apparatus and full protective gear
Special Procedures: Cool exposed containers with water spray; avoid runoff into sewers or waterways
Explosion Hazards: Product can form flammable mixtures with air; avoid sources of ignition
Personal Precautions: Prevent skin and eye contact; ventilate area; use prescribed PPE
Environmental Precautions: Limit product release to soil, waterways, and drainage systems; notify authorities in case of significant spills
Cleanup Methods: Absorb with inert material (sand, earth, vermiculite), place in appropriate chemical waste container; wash spill surface with water and detergent after cleanup
Decontamination: Wash contaminated items before reuse
Handling: Prevent release of dust or aerosol by using enclosures or local exhaust; do not breathe dust, vapor, or mist; avoid skin and eye exposure by wearing PPE and washing thoroughly after handling
Storage Requirements: Store in tightly closed, properly labeled containers in cool, well-ventilated areas away from strong acids, oxidizers, and moisture; keep away from light and sources of ignition; avoid incompatible containers such as aluminum, copper, or galvanized metals
Special Advice: Regularly inspect containers for leaks or signs of wear
Exposure Limits: No established occupational exposure limits for this product; use engineering controls to prevent exposures above recommended guidelines
Engineering Controls: Local exhaust ventilation or process enclosure suggested for vapor/dust control; ensure eyewash stations and emergency showers in work area
Personal Protection: Use chemical-resistant gloves (nitrile, neoprene), splash-proof goggles or face shield, chemical-resistant clothing and boots; use NIOSH-approved respirator if vapor or aerosol may be present
Hygiene Measures: Wash hands, face, and exposed skin before breaks and after finishing work

Vapor Density: >1 (air = 1)
Specific Gravity: ~0.85–0.9 (25°C)
Solubility: Slightly soluble in water; soluble in alcohols and organic solvents
Partition Coefficient (n-octanol/water): >5 (estimated, strongly lipophilic)
Auto-Ignition Temperature: 300°C (estimated)
Decomposition Temperature: >200°C
Viscosity: High at room temperature, decreases on heating
Stability: Stable under recommended conditions
Chemical Stability: Sensitive to strong acids, oxidizing agents; may react vigorously with these materials

Hazardous Decomposition Products: Ammonia, nitrogen oxides, carbon monoxide, carbon dioxide, hydrocarbons may form on thermal decomposition or combustion
Polymerization: Will not polymerize under normal conditions
Acute Toxicity: Oral and dermal exposure can cause toxicity; estimated LD50 (oral, rat): 1000–2000 mg/kg
Skin Irritation: Causes burns and blistering on contact
Eye Irritation: Causes severe burns, possible irreversible damage
Inhalation Risk: May cause irritation to respiratory tract; coughing, shortness of breath can follow
Chronic Effects: Prolonged skin contact may lead to dermatitis, sensitization possible but not common
Carcinogenicity: No data indicate carcinogenicity for tallow primary amine; not listed by IARC, NTP, OSHA
Mutagenicity: No data indicate mutagenic effects
Reproductive Toxicity: No data indicate reproductive effects
