Special Protective Actions for Firefighters: Wear self-contained breathing apparatus and full protective gear
Advice: Remain upwind and keep containers cool with water spray to reduce vapors
Personal Precautions: Wear gloves, eye protection, dust mask or respirator
Environmental Precautions: Prevent large spills from entering drains or waterways
Cleanup Methods: Sweep up without generating dust, place in suitable containers for disposal, ventilate the area
Advice for Handling Spills: Wash spill area with water after pick-up is complete
Precautions for Safe Handling: Avoid dust formation; use only in well-ventilated areas; wear appropriate protective gear
Safe Storage Conditions: Store in tightly closed, labeled containers in a cool, dry, well-ventilated area; keep away from moisture and incompatible substances such as strong acids
Specific Requirements: Keep container tightly closed; avoid prolonged exposure to atmospheric moisture
Control Parameters: Exposure limits not established for this compound
Engineering Controls: Use fume hood or local exhaust
Personal Protective Equipment: Chemical safety goggles, compatible gloves (nitrile recommended), lab coat or apron, dust mask or particulate respirator for powder manipulation
