First aid

  • Eyes: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. Immediately transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop. Skin: Immediately flood affected skin with water while removing and isolating all contaminated clothing.[1]
  • (General first aid procedures) Eye: Irrigate immediately - If this chemical contacts the eyes, immediately wash (irrigate) the eyes with large amounts of water, occasionally lifting the lower and upper lids. Get medical attention immediately. Skin: Water flush promptly - If this chemical contacts the skin, flush the contaminated skin with water promptly. If this chemical penetrates the clothing, immediately remove the clothing and flush the skin with water promptly.[5]
  • Fresh air, rest. Refer for medical attention.[3]
  • Remove contaminated clothes. Rinse skin with plenty of water or shower.[3]

Storage

  • Fireproof. Separated from strong oxidants, strong bases and strong acids. Cool.[3]
  • Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage.[6]

Incompatibilities

  • Incompatible materials: Strong oxidizing agents, Strong reducing agents, Strong bases.[6]
  • Contact with nitrates, strong oxidizers, strong alkalies, and strong acids may cause fires and explosions.[6]
  • Ignites on contact with potassium tert-butoxide.[6]
  • Nitrates; strong oxidizers, alkalis & acids.[6]
