First Aid Measures

Inhalation: Remove victim to fresh air immediately; keep patient still, administer oxygen if necessary, seek medical attention if breathing difficulty persists
Skin Contact: Remove contaminated clothing, flush skin with large amounts of water for at least 15 minutes, seek medical attention if irritation develops
Eye Contact: Rinse eyes cautiously with water for several minutes, remove contact lenses if possible, continue rinsing, seek prompt medical attention
Ingestion: Do not induce vomiting, rinse mouth, give small quantities of water if conscious, call poison control or medical provider immediately
Note to Physician: Treat symptomatically, monitor for respiratory distress, consult MSDS for supplementary information

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray (preferred), foam, dry powder (do not use CO2/halogens)
Specific Hazards: Organic peroxides release oxygen; intense heat, risk of rapid decomposition, explosion, toxic gas generation
Protective Equipment: Firefighters require self-contained breathing apparatus (SCBA), chemical-resistant protective clothing
Special Procedures: Cool containers with flooding amounts of water, stay upwind, avoid run-off into drains, evacuate area
Byproducts: Carbon monoxide, carbon dioxide, hydrocarbons, possible peroxides
Unusual Hazards: Explosive vapors or decomposition products—delayed ignition risks exist well after visible flames subside

Accidental Release Measures

Personal Precautions: Evacuate, ventilate, restrict access, remove ignition sources, wear chemical-resistant gloves, splash goggles, coveralls
Containment: Dike spill area with inert absorbent (sand, vermiculite), prevent entry into waterways, isolated from flammable materials
Cleanup: Scoop up residuals using non-sparking tools, transfer to appropriate chemical waste containers, seal securely
Disposal: Contact licensed waste handler for approved combustion or chemical neutralization; never flush to sewer
Decontamination: Wash spill surface thoroughly, ventilate area
Reporting: Notify authorities if environmental release exceeds reportable quantity

Handling and Storage

Handling: Only handle under chemical fume hood; prevent static buildup, avoid rough handling or dropping containers, ground equipment during transfer
Hygiene: Wash thoroughly after handling, avoid contact with skin, eyes and clothing
Storage Temperature: 2–8°C (refrigerated), avoid freezing
Storage Conditions: Store away from sunlight, heat sources, acids, bases, metal salts, flammable solids or liquids
Containers: Use non-reactive, tightly sealed containers with secondary containment for bulk storage
Incompatibilities: Acids, alkalies, amines, reducing agents, combustibles, copper, brass, iron
Shelf Life: Storage recommendations must be regularly reviewed for stability testing and date tracking

Exposure Controls and Personal Protection

Occupational Exposure Limits: No established OSHA/ACGIH threshold limit value, handle as potentially hazardous
Engineering Controls: Local exhaust ventilation, explosion-proof electrical fittings, automated transfer lines where feasible
Personal Protective Equipment: Splash goggles or face shield, flame-resistant lab coat, chemical-resistant gloves (nitrile or Viton), anti-static footwear
Respiratory Protection: Approved organic vapor respirator or air-purifying mask for large scale or accidental releases
Other Protective Measures: Emergency eyewash and safety shower within immediate work area, maintain clean work practices to prevent contamination

Physical and Chemical Properties

Physical State: Liquid, colorless to yellowish
Odor: Characteristic, organic odor (pungent note possible at higher concentrations)
Melting Point: <0°C (often below freezing temperatures)
Boiling Point: >150°C (breakdown likely before boiling)
Auto-Ignition Temperature: >230°C
Decomposition Temperature: 80–90°C—exothermic breakdown possible
Vapor Pressure: Low at ambient temperature
Solubility: Insoluble in water; soluble in alcohol, ketones, most organic solvents

Stability and Reactivity

Chemical Stability: Stable under recommended refrigerated storage conditions and away from direct light
Thermal Decomposition: Risk increases rapidly >50°C; violent decomposition with rapid temperature spikes
Reactivity: Strong oxidizer, reacts with organic material, metals, acids, bases, and reducing agents
Conditions to Avoid: High temperatures, contamination, friction, impact, direct sunlight, incompatible chemicals
Hazardous Polymerization: Not likely in isolation, but reaction with select monomers can cause runaway reactions
Decomposition Products: Carbon dioxide, carbon monoxide, peroxides, hydrocarbons, possible acid gases

Toxicological Information
