Hazards & Safety

• Hazard Statements: H225 Highly flammable liquid and vapor; H319 Causes serious eye irritation; H336 May cause drowsiness or dizziness.

• Prevention: Keep away from heat/sparks/open flames; keep container tightly closed; ground/bond; use explosion-proof equipment and non-sparking tools; avoid breathing vapors; use only with adequate ventilation; wear protective gloves/eye protection.

• Response: IF ON SKIN (or hair): remove contaminated clothing, rinse skin/shower. IF IN EYES: rinse cautiously with water, remove contacts, continue rinsing. IF INHALED: move to fresh air. If symptoms persist, get medical attention. Store in a cool, well-ventilated place. Dispose per regulations.

First Aid Measures

• Eyes: Rinse with water for ≥15 minutes; get medical attention if irritation persists.

• Skin: Wash with soap and water; launder contaminated clothing before reuse.

• Inhalation: Remove to fresh air; support breathing if needed.

• Ingestion: Do not induce vomiting; contact physician/poison control.

• Notes: Treat symptomatically; consider target-organ CNS effects.

Fire & Explosion Data

• Flash Point: −4 °F (−20 °C)

• Extinguishing Media: Alcohol-resistant foam, dry chemical, CO₂, dry sand; do not use water jet.

• Special Hazards: Vapors may form explosive mixtures with air; static ignition possible.

• Firefighting: Full PPE and SCBA; cool containers with water spray; prevent runoff to drains.

Handling & Storage

• Use polyethylene/lined steel/stainless systems; protect containers from damage.

• Ground and bond all transfer equipment; use non-sparking tools and explosion-proof ventilation.

• Store tightly closed, cool, dry, isolated, and well-ventilated; keep away from ignition sources and incompatibles.

Exposure & PPE

• Exposure Limits: ACGIH TWA 250 ppm; OSHA PEL 1000 ppm (2400 mg/m³).

• Controls: Provide local exhaust; ensure eyewash/safety shower access.

• PPE: Safety glasses; suitable gloves; protective clothing as needed; respiratory protection if exposure may exceed limits.
