Advice for Firefighters: Approach from upwind, avoid run-off to sewers, fight fire from a safe distance.
Personal Precautions: Evacuate unnecessary personnel, ventilate area, put on protective equipment—gloves, goggles, boots, coveralls
Environmental Precautions: Prevent product from entering drains, sewers, streams, or soil, contain spillage with non-combustible absorbent materials such as sand or earth
Spill Cleanup Methods: Collect spilled material with shovel or absorbent, place in labeled container for disposal, decontaminate area with water with plenty of ventilation, dispose collected material following local and national regulations.
Handling: Use only in well-ventilated areas, avoid contact with skin, eyes, and clothing, do not eat, drink, or smoke when working, avoid generating mist or aerosols
Storage: Store in tightly closed original container in a cool, dry, well-ventilated area away from incompatible substances like acids and oxidizers, protect from freezing and direct sunlight, always keep away from food, feed, and out of children's reach
Storage Class: Corrosive liquid storage area with secondary containment, proper signage, eye-wash station and emergency shower nearby.
Exposure Limits: No specific OSHA or ACGIH exposure limits established for this compound; minimize airborne concentrations
Engineering Controls: Use local exhaust ventilation, general ventilation, or fume hood for bulk handling
