First aid

  • Inhalation: Remove victim from exposure; if breathing is difficult, administer oxygen; if breathing has stopped, begin artificial respiration. EYES or skin: Wash with copious amounts of water for 15 min. (USCG, 1999)[1]
  • Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.[3]
  • Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .[3]
  • First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.[3]

Storage

  • Fireproof. Separated from strong oxidants, strong acids and food and feedstuffs.[3]
  • Fireproof. Separated from strong oxidants, strong acids, food and feedstuffs.[4]

Incompatibilities

  • Violent or explosive reaction with N-chlorosuccinimide[4]
