Hazards from Combustion: Produces carbon oxides (CO, CO2) under combustion. No highly toxic or unusual gases expected.
Special Protective Equipment: Firefighters must wear self-contained breathing apparatus and full protective gear.
Advice for Firefighters: Keep containers cool with water spray; prevent runoff from entering drains and water sources where feasible.
Unusual Fire Hazards: Product is combustible at very high temperatures, not highly flammable under typical conditions.
Personal Precautions: Wear suitable gloves, goggles, and dust mask if large quantities are involved. Prevent skin and eye contact.
Environmental Precautions: Prevent from entering drains, waterways, and soil. Dilute residues with plenty of water.
Method for Clean-up: Sweep up spills using a method that minimizes dust generation. Place in suitable labeled containers for disposal. Ventilate area and wash the spill site after material pickup is complete.
Recommended Tools: Non-sparking tools, appropriate dust control measures.
Disposal: Dispose of waste according to local or national regulations.
Handling: Use in well-ventilated areas. Avoid creating dust. Use personal protective equipment including gloves and goggles. Always wash hands after handling.
Storage: Keep container tightly closed in a cool, dry place. Store away from incompatible materials, such as strong oxidizing agents and bases. Recommended storage temperatures: 15–25°C.
Storage Class: General chemicals, no special restrictions, but keep segregated from oxidizers.
Engineering Controls: Use local exhaust ventilation or general dilution ventilation to minimize dust exposure.
Personal Protective Equipment:
• Eye Protection: Chemical splash-resistant goggles.
• Skin Protection: Chemical-resistant nitrile or neoprene gloves; long sleeves or lab coat.
• Respiratory Protection: Dust mask or particulate respirator if dust is generated or exposures approach limits.
Exposure Limits: No established occupational exposure limits in US OSHA or ACGIH, but control dust to minimal levels.
Hygiene Recommendations: Wash hands after use, do not eat or drink in work area, change contaminated clothing and clean before reuse.
