Special Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear
Advice for Firefighters: Cool containers with water spray, avoid inhalation of combustion products, keep upwind of fire
Flash Point: Data specific to product grade required (handle as potentially flammable-even if value is high)
Explosion Hazards: Material may emit flammable vapors at high temperatures; closed containers can rupture under fire conditions

Accidental Release Measures

Personal Precautions: Evacuate area of all unnecessary personnel; ventilate enclosed areas; avoid inhalation of vapors and skin or eye contact
Protective Equipment: Use chemically resistant gloves, safety goggles, and respirator suitable for organic vapors
Environmental Precautions: Prevent product from entering drains, sewers, or watercourses; contain spill where possible
Cleanup Procedures: Absorb spill with inert material (sand, vermiculite); collect in closed, labeled container for proper disposal; ventilate area after cleanup
Disposal: Waste must be disposed of in accordance with local, regional, and national regulations to minimize environmental impact

Handling and Storage

Handling: Avoid inhalation, ingestion, or skin contact; handle containers with care; use only in well-ventilated areas or fume hood
Storage: Store in tightly sealed container in cool, dry, well-ventilated location away from incompatible substances such as strong oxidizers and acids
Temperature Controls: Keep at consistent room temperature; prevent freezing or overheating
Specific Use Recommendations: Always handle using chemical-resistant gloves and eye protection; prevent static discharge in working area

Exposure Controls and Personal Protection

Engineering Controls: Use local exhaust ventilation, fume hoods, and mechanical air circulation as needed
Personal Protective Equipment: Chemical splash goggles, nitrile or neoprene gloves, lab coat, suitable respirator if airborne concentrations exceed limits
Exposure Limits: Not established for this specific compound; follow best practices for laboratory chemicals
Environmental Exposure Controls: Filter air emissions from laboratory work if feasible; avoid release to the wider environment
Hygiene Measures: Wash thoroughly after handling; remove contaminated clothing and wash before reuse
