First Aid Measures

Inhalation: Move to fresh air, keep at rest in a position comfortable for breathing, monitor for coughing or difficulty breathing, seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing immediately, wash affected area with plenty of soap and water, do not use solvents, monitor for redness or swelling, seek medical help if rash develops
Eye Contact: Rinse slowly with clean water for at least 15 minutes, remove contact lenses if present, continue rinsing, see a doctor if irritation continues
Ingestion: Rinse mouth with water, do not induce vomiting unless instructed by medical personnel, seek medical advice promptly
Note to Physicians: Treat symptomatically, monitor for delayed allergic response or respiratory complications due to sensitizer potential

Fire-Fighting Measures

Suitable Extinguishing Media: Carbon dioxide, foam, dry chemical powder, avoid water jet which may spread product
Hazardous Combustion Products: Acrid smoke, carbon monoxide, carbon dioxide, possible production of acrolein or other irritating aldehydes
Special Protective Equipment: Firefighters wear self-contained breathing apparatus and full turnout gear
Advice for Firefighters: Isolate scene, keep run-off out of sewers and waterways, cool containers with water spray to prevent rupture
Explosion Hazard: Material does not sustain combustion but vapors may form explosive mixtures with air above 90°C

Accidental Release Measures

Personal Precautions: Wear chemical-resistant gloves, eye protection, long-sleeved clothing, use respiratory protection if vapor levels high
Environmental Precautions: Prevent entry into drains, soil, or surface water, inform authorities if major spill causes risk to waterways
Clean-up Methods: Absorb spill with sand, earth, or inert material, do not use combustible absorbents, shovel material into suitable containers for disposal, ventilate affected area
Decontamination: Wash spill site with soap and water after cleanup, dispose of cleaning material as hazardous waste

Handling and Storage

Precautions for Safe Handling: Avoid direct contact with skin and eyes, do not breathe vapor or mist, use in well-ventilated areas or with local exhaust, keep away from open flames, hot surfaces, and sources of ignition
Storage Conditions: Store in tightly closed, light-resistant, and labeled containers, keep away from strong acids/bases, keep cool (below 35°C), protect from sunlight, store separately from oxidizers
Engineering Controls: Install eyewash stations and safety showers near work area, avoid mechanical impact that can cause container breakage

Exposure Controls and Personal Protection

Occupational Exposure Limits: No established OSHA or ACGIH exposure limits, minimize exposure by engineering controls
Engineering Controls: Local exhaust ventilation in use area, well-organized spill response plan
Personal Protective Equipment: Butyl rubber or nitrile gloves, chemical splash goggles or face shield, flame-resistant lab coats, use of organic vapor respirator in absence of ventilation
Hygiene Measures: Wash hands and exposed skin before breaks, after work, remove contaminated clothing immediately, do not eat, drink, or smoke in the work area
