Special Procedures: Evacuate area; cool containers exposed to fire with water; keep runoff out of drains and waterways
Personal Precautions: Isolate area; ventilate; keep unprotected persons away; avoid inhaling fumes
Protective Equipment: Use gloves, chemical splash goggles, face shield, apron; respiratory protection in confined or poorly ventilated areas
Environmental Precautions: Prevent run-off into sewers, soil, and water bodies; alert environmental authorities as necessary
Methods for Clean-Up: Contain spill with inert absorbent material (sand, earth); collect in suitable container for disposal; wash residual area with plenty of water
Spill Reporting: Notify authorities if release exceeds reportable quantity
Handling: Avoid contact with skin, eyes, and clothing; handle under well-ventilated conditions; don’t breathe mist, vapor, or spray
Storage Conditions: Store in tightly closed containers; keep in cool, dry, well-ventilated areas away from heat sources, oxidizers, and acids
Transfer Precautions: Use pumps and grounded lines to minimize static discharge
Incompatibility: Strong acids, alkalies, oxidizing agents
Other Recommendations: Store away from food, beverages, feed; label all containers and restrict access
Occupational Exposure Limits: No established OSHA PEL or ACGIH TLV; recommend inhalable exposure not to exceed 1 mg/m³
