Advice for Firefighters: Prevent runoff from entering watercourses, use water spray to cool containers
Personal Precautions: Ventilate area, prevent dust formation, avoid breathing dust, wear gloves and safety goggles
Environmental Precautions: Prevent bulk material from entering waterways or sewer systems, sweep or vacuum up spill without raising dust
Clean-Up Methods: Collect with shovel or broom, place material in suitable closed containers for disposal, wash area with water after cleanup
Handling Recommendations: Keep container tightly closed when not in use, work in ventilated area, avoid eating or smoking during handling, wash hands after handling
Storage Requirements: Store in cool, dry area away from strong oxidizing agents, acids, or damp environments, keep away from direct sunlight and sources of moisture
Exposure Limits: No specific exposure limits established by OSHA, NIOSH, or ACGIH
Engineering Controls: General room ventilation usually adequate, use local exhaust for dusty conditions
Personal Protective Equipment: Safety goggles or face shield, chemical-resistant gloves, dust mask or respirator if airborne dust exceeds comfort level, work clothes to prevent skin contact
Physical State: White crystalline powder, granules, or flakes
