Special Protective Equipment for Firefighters: Full chemical protective suits and self-contained breathing apparatus
Fire/Explosion Hazards: May burn with invisible flame, containers may explode if heated or exposed to fire, reacts with strong oxidizers to form toxic byproducts
Advice for Firefighters: Prevent fire water run-off from entering waterways, use water spray to cool exposed containers but avoid direct contact with material
Personal Precautions: Wear full chemical protective clothing, including gloves, eye/face protection, and respiratory protection, keep unprotected persons away
Environmental Precautions: Prevent entry into drains, soil, water sources, or sewers; report releases as required by regulations
Containment Methods: Stop leak if safe to do so, use inert absorbent material (such as sand or vermiculite) to control spill
Clean-up Procedures: Collect absorbed material in labeled containers for disposal, decontaminate spill area thoroughly, ventilate area well after clean-up
Emergency Procedures: Evacuate all unnecessary personnel, notify emergency services if spillage is large or if there is a risk of environmental contamination
Handling: Only handle inside chemical fume hoods, do not handle without adequate training, avoid any direct contact, do not eat, drink, or smoke near area of use
Protective Measures: Use appropriate tools for manipulation, employ local exhaust ventilation, ground all equipment to prevent static discharge
Storage Conditions: Store in tightly sealed containers in a cool, dry, and well-ventilated area away from sources of ignition and incompatible substances (oxidizers, acids, alkalis)
Segregation: Keep separate from food, beverages, animal feed; segregate from acids, oxidizers, and strong bases
Specific End Use(s): As a laboratory reagent or for industrial synthesis in controlled environments
Occupational Exposure Limits: No established OSHA, NIOSH, or ACGIH exposure limits; minimize exposure as much as possible
Engineering Controls: Use fume hoods, local exhaust ventilation, and process enclosures; monitor airborne levels if handling significant quantities
Personal Protective Equipment: Chemical-resistant gloves (nitrile, butyl), full-length laboratory coat, safety goggles, face shield for splash risk, appropriate respiratory protection (P3 or supplied air respirator)
Hygiene Measures: Wash hands and face before eating, drinking, or leaving work area; remove contaminated clothing and equipment before entering eating areas
Environmental Exposure Controls: Prevent chemical release into surface waters, groundwater, and soil; contain and properly manage all wastes and emissions
