Accidental Release Measures

Personal Precautions: Eliminate sources of ignition, ventilate area, use appropriate personal protective equipment (PPE), avoid inhalation and direct contact
Environmental Precautions: Prevent from entering soil, drains, watercourses; inform relevant authorities if pollution occurs
Methods for Containment and Cleaning Up: Small spills: absorb with inert material (sand, earth), collect in chemical waste container; large spills: dike far ahead for later recovery, use explosion-proof equipment; dispose per local regulations
Decontamination: Wash affected area with copious water, clean tools with detergent
Emergency Procedures: Evacuate unnecessary personnel, secure ventilation

Handling and Storage

Handling Procedures: Handle in a well-ventilated area, keep away from sources of ignition and heat, use non-sparking tools and equipment, avoid inhalation of vapors, prevent contact with skin and eyes
Storage Conditions: Store in cool, dry, tightly closed containers, away from incompatible materials like strong oxidizers and acids, store locked up and separated from food and feedstuffs
Special Requirements: Ground and bond containers during transfer to minimize static discharge
Hygiene Measures: Wash thoroughly after handling, remove contaminated clothing immediately
