First Aid Measures
Inhalation: Move affected person to fresh air immediately, keep at rest, seek medical attention if breathing is difficult
Skin Contact: Remove contaminated clothing, rinse affected area under running water for at least 15 minutes, call physician
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if possible, continue rinsing, seek ophthalmological care
Ingestion: Rinse mouth without swallowing, do not induce vomiting, seek immediate medical assistance
Self-Protection: Wear gloves during first aid, avoid exposure to yourself while assisting others
Fire-Fighting Measures
Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide, sand
Unsuitable Extinguishing Media: Water jet, due to risk of spreading
Hazardous Combustion Products: Nitrogen oxides, carbon monoxide, ammonia, irritating fumes
Special Firefighting Procedures: Full protective gear and self-contained breathing apparatus
Special Hazards: May produce dense, noxious smoke under combustion; containers may rupture if exposed to extreme heat
Firefighting Precautions: Isolate scene, prevent water from contaminating drains or watercourses
Accidental Release Measures
Personal Precautions: Evacuate area, ventilate, use appropriate personal protective equipment
Environmental Precautions: Prevent contamination of soil, waterways, drains
Cleanup Methods: Collect spilled product using non-combustible absorbent material, scoop into secure, labeled containers for disposal
Spillage Response: Wash affected area with soap and water after cleanup; do not return recovered product to the original container
Handling and Storage
Safe Handling: Use in well-ventilated area, avoid contact with skin, eyes, clothing, keep containers tightly sealed when not in use
Storage Conditions: Store at room temperature in dry, cool, well-ventilated area
Incompatible Materials: Avoid contact with acids, oxidizing agents, strong bases
Storage Equipment: Store in corrosion-resistant containers with appropriate inner liners
Hygiene Practices: Avoid eating, drinking, smoking in handling areas; wash hands after use
Exposure Controls and Personal Protection
Exposure Limits: No occupational exposure limit established for stearyl amine; minimize exposure by engineering controls
Engineering Controls: Use local exhaust ventilation, eyewash stations, safety showers
Personal Protection: Nitrile or neoprene gloves, chemical goggles, faceshield, long-sleeved lab coat
Respiratory Protection: Use approved respirator if ventilation is inadequate
Environmental Controls: Prevent product from reaching sewers or waterways; apply local regulations

Stability and Reactivity
Chemical Stability: Stable under standard conditions of use and storage
Reactivity: May react with acids producing heat and toxic fumes; reacts with strong oxidizing agents
Hazardous Decomposition Products: Ammonia, nitrogen oxides, carbon monoxide
Polymerization: Not known to polymerize under normal conditions
Conditions to Avoid: Excess heat, open flame, incompatible materials
Toxicological Information
Routes of Entry: Inhalation, skin and eye contact, ingestion
Acute Toxicity: Oral LD50 (rat) ~ 300 – 2000 mg/kg; may cause serious injury to mucous membranes
Chronic Effects: Prolonged skin contact may result in dermatitis or sensitization
Corrosive Effects: Severe irritation and burns to skin, eyes, and respiratory tract
Carcinogenicity: Not classified as carcinogenic based on available data
Other Hazards: Reports of respiratory distress or asthma-like symptoms in high-concentration settings
Ecological Information
Aquatic Toxicity: Toxic to aquatic organisms, may cause long-term adverse effects
Persistence and Degradability: Slow biodegradation under typical environmental conditions
Bioaccumulation Potential: Tendency to accumulate in aquatic organisms due to high fat solubility
Mobility in Soil: Limited due to low water solubility; binds to soil particles
Other Effects: Avoid release into natural water systems, as contamination can disrupt aquatic life
Disposal Considerations
Waste Treatment: Dispose of contents and container according to local, regional, and national regulations
Disposal Methods: Incineration preferred where permitted; landfilling approved in engineered facilities only
Packaging Disposal: Empty containers should be triple-rinsed before disposal or recycling
Avoid: Entry into drains, sewers, or waterways; uncontrolled incineration; landfill use without permission
