Eye Contact: Flush with clean water for at least 15 minutes; medical evaluation required
Swallowing: Rinse mouth; avoid giving anything by mouth if unconscious; get emergency help
Symptoms to Watch For: Drowsiness, dizziness, unusually rapid or irregular heartbeat, vomiting, seizures
Prevention Tips: Ventilation in workspace, protective clothing, prompt clean-up of spills
Suitable Extinguishing Media: Water spray, carbon dioxide, dry chemical powder, foam
Special Hazards: Decomposition may generate toxic fumes such as nitrogen oxides, hydrogen chloride
Protective Equipment: Full protective gear with independent breathing apparatus
Advice for Firefighters: Keep cool with water spray; prevent run-off into sewers; control dust near flames
Personal Protection: Gloves, safety goggles, lab coat, respiratory protection in poorly ventilated spaces
Spill Containment: Isolate area, avoid raising dust, scoop up material without creating airborne particles
Cleanup Methods: Sweep up spills into appropriate waste container; vacuum with HEPA filter if available
Environmental Impact: Avoid release to environment; prevent entry into drains or waterways
Safe Handling: Work in well-ventilated spaces, avoid contact with skin and eyes, keep containers tightly closed
Hygiene Practices: Avoid eating, drinking, smoking around material; wash thoroughly after handling
