Fire Fighting Instructions: Isolate area, remove containers from fire zone if safe, spray unopened containers with water to cool.
Personal Precautions: Evacuate area, ventilate space, avoid breathing vapors, wear appropriate PPE (goggles, gloves, chemical-resistant clothing, respirator if needed).
Environmental Precautions: Prevent spill from entering drains, soil, or watercourses, use barriers if necessary, report significant releases according to local/regional regulations.
Spill Cleanup Methods: Contain the spill with non-combustible absorbent material like sand or earth, collect into chemical waste container, neutralize with sodium bicarbonate, wash area with copious water, ventilate area thoroughly.
Safe Handling: Work in well-ventilated areas, minimize contact with skin, eyes, and clothing, keep away from ignition sources, use explosion-proof equipment, avoid direct inhalation of vapors, use non-sparking tools.
Storage Requirements: Store tightly sealed in original or compatible corrosion-resistant containers, in a cool, dry, well-ventilated area, away from incompatible substances such as oxidizers and alkalines, keep container out of sunlight, ground all equipment.
