Firefighting Instructions: Isolate area, cool surrounding containers with water spray
Personal Precautions: Keep unnecessary persons away, avoid dust, ventilate area well, put on gloves, eye shield, and dust mask
Environmental Precautions: Prevent release to water systems, do not allow runoff into drains
Clean-Up Methods: Sweep up solid powder with minimum dust, use damp paper or HEPA vacuum for residues, collect in suitable closed container for disposal, wash affected surface with soap and water
Spill Size Response: For small spills, use wipe-up and disposal procedure; for large releases, contact safety specialist and follow local protocols
Safe Handling: Operate in a well-ventilated area, avoid direct contact with powder, wash hands after use, keep containers tightly closed

Technical Measures: Use personal protective equipment, handle away from food or beverages
Storage Requirements: Store in cool, dry place, temperature between 2-8°C recommended, protect from sunlight, keep in original packaging, restrict access
Special Conditions: Store separate from hormone-sensitive materials and out of general traffic zones
Engineering Controls: Use chemical fume hood or local exhaust ventilation to minimize airborne particles
Exposure Limits: No OSHA or ACGIH exposure limits established, prudent avoidance advised
Protective Equipment: Nitrile gloves, lab coat, safety glasses with side shields or goggles, particle mask or respirator for dust work
Hygiene Measures: Do not eat, drink, or smoke in work area, wash exposed skin after use, discard contaminated clothing safely
Environment Controls: Prevent environmental discharge, use closed-system equipment when possible
