Substance: Butylamine
CAS Number: 109-73-9
Concentration: 99% or greater
Impurities: May contain trace water or stabilizers; check supplier data for specifics
Inhalation: Move person outdoors, provide fresh air immediately. Seek medical attention if breathing is difficult or symptoms persist.
Skin Contact: Remove affected clothing. Rinse skin with water for at least 15 minutes. Seek medical advice for irritation, blistering, or burns.
Eye Contact: Rinse with water for at least 15 minutes, holding eyelids apart. Remove contact lenses if present and easy. Seek urgent medical care.
Ingestion: Rinse mouth with water. Do not induce vomiting. Get medical help right away. If unconscious, do not give anything by mouth.
Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide, water spray (do not use direct water jet)
Specific Hazards: Forms flammable or explosive mixtures with air. Vapors may travel to source of ignition and flash back. Decomposes in fire to release nitrogen oxides, carbon monoxide, carbon dioxide.
Protective Equipment: Firefighters wear full protective gear, self-contained breathing apparatus.
Special Procedures: Use water spray to cool exposed containers. Prevent runoff from firefighting from entering water systems.
Personal Precautions: Evacuate unnecessary personnel, ventilate area, avoid breathing vapors, prevent skin and eye contact.
Environmental Precautions: Prevent release into sewers, soil, waterways.
Spill Cleanup Methods: Wear protective clothing, gloves, goggles. Absorb with inert material (sand, earth, vermiculite), scoop into suitable closed containers. Ventilate and wash spill area after material pickup. Dispose as hazardous waste.
Handling: Handle in fume hood. Open containers in well-ventilated areas. Avoid inhaling vapors, minimize exposure. Wear protective gear; handle empty containers with care as residues remain hazardous.
Storage: Store in a tightly closed container. Keep from heat, open flames, direct sunlight. Use compliant chemical storage area with explosion-proof fixtures. Segregate from acids, acid chlorides, strong oxidizers. Store at room temperature, away from incompatible materials.
Occupational Exposure Limits: ACGIH TLV: 5 ppm TWA, OSHA PEL: 5 ppm TWA
Engineering Controls: Use local exhaust ventilation, explosion-proof equipment. Monitor vapor concentrations.
Personal Protective Equipment: Chemical-resistant gloves (nitrile, neoprene), safety goggles, face shield, flame-resistant clothing, compatible respirator if ventilation inadequate. Eyewash and safety shower accessible.

LD50 (oral, rat): 366 mg/kg
LD50 (dermal, rabbit): 685 mg/kg
Inhalation Effects: May cause dizziness, headache, nausea, respiratory tract irritation, chemical pneumonitis
Chronic Effects: Prolonged exposure may lead to dermatitis, respiratory impairment, damage to mucous membranes
Carcinogenicity: Not listed by IARC, NTP, OSHA
Other: Sensitization not commonly reported, but use caution
Aquatic Toxicity: Toxic to aquatic life; LC50 (fish, 96h): 46 mg/L (Oncorhynchus mykiss)
Persistence: Not persistent; rapidly degrades in environment
Mobility in Soil: High, due to water solubility
Bioaccumulation: Low potential
Other Adverse Effects: Raises pH in water, potentially harmful to aquatic organisms by disrupting cell function
Precautions: Prevent runoff or direct release into surface water or groundwater
Waste Disposal Methods: Incinerate in chemical incinerator under controlled conditions following federal, state, local, and national regulations. Do not discharge to sewer systems.
Contaminated Packaging: Triple rinse containers, remove labels, puncture, and dispose as hazardous waste
Special Considerations: Coordinate with licensed hazardous waste disposal contractor. Do not attempt disposal without appropriate permits and guidance.
