Inhalation: Remove person to fresh air, seek medical attention if breathing becomes difficult or irritation persists, keep at rest in a position comfortable for breathing
Skin Contact: Immediately wash with plenty of soap and water, remove contaminated clothing and shoes, rinse thoroughly, do not attempt neutralization, seek medical help for burns or persistent irritation
Eye Contact: Rinse eyes cautiously with water for at least 15 minutes, remove contact lenses, continue rinsing, consult a physician immediately
Ingestion: Rinse mouth, do not induce vomiting, call poison control or physician, give small amounts of water only as tolerated
Note to Physician: Treat symptomatically, monitor for chemical pneumonitis if inhaled, maintain airway and watch for delayed pulmonary symptoms
Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam, water fog to cool fire-exposed containers
Unsuitable Media: Direct water jets: risk of spreading contamination
Specific Hazards: May emit toxic fumes of nitrogen oxides and carbon compounds when burning, combustible at high temperature
Protective Equipment: Full turnout gear, self-contained breathing apparatus required for large fires
Fire-Fighting Advice: Approach fire from upwind, use methods minimizing the spilling of contaminated runoff, contain water used to extinguish fire
Decomposition Products: Nitrogen oxides, carbon monoxide, carbon dioxide, amine vapors
Personal Precautions: Evacuate area where vapors or spills occur, ventilate area, wear suitable chemical protective gloves, goggles, and boots
Environmental Precautions: Prevent entry into sewers, surface water, or soil; report any uncontrolled releases to local authorities
Containment: Dike and absorb spill with inert material such as sand, earth, or vermiculite
Cleanup Methods: Collect absorbed material in appropriate labeled drums for disposal, clean contaminated surfaces with plenty of water, ventilate area, avoid direct contact with DNA or organic material that could react
Decontamination: Wash area with soapy water, collect washings for regulated disposal, do not allow rinse to enter drains
Handling: Handle with local exhaust ventilation, avoid release of vapors or mist, avoid direct contact with skin and eyes, do not eat, drink, or smoke while handling
Hygiene Practices: Wash thoroughly after handling, launder contaminated clothing before reuse, change gloves if contamination occurs
Storage Conditions: Store in tightly closed original containers, away from acids, oxidizing agents, and strong bases, in a dry, ventilated place below 30°C
Storage Class: Corrosive solid, separated from foodstuffs, oxidizers, and incompatible chemicals
Packaging Requirements: Use corrosion-resistant, leak-proof containers clearly labeled for hazardous chemical storage
Occupational Exposure Limits: No specific limits established by OSHA, ACGIH, or EU; treat as irritant
Engineering Controls: Use mechanical exhaust or vented enclosures, eye wash stations, and emergency showers in work area
Hand Protection: Nitrile or neoprene gloves resistant to amine compounds
Eye Protection: Chemical goggles or face shield required for splash protection
Skin Protection: Long sleeves, impermeable apron, rubber boots for spill or bulk handling
Respiratory Protection: Use approved respirator for vapor/mist if ventilation is insufficient
Environmental Controls: Use bunds, sumps, or sealed flooring to avoid entry into drains or soil
