First aid

  • Call a physician. Inhalation: Remove to fresh air. If not breathing, give artificial respiration. Give oxygen if breathing is difficult. Eyes: 15-Minute emergency eye washing. See physician as soon as possible. Skin: Wash with soap and water. Flush for at least 15 minutes. Remove contaminated clothing. Ingestion: Wash mouth, drink water, get medical aid. (USCG, 1999)[1]
  • General First Aid: · Call 911 or emergency medical service. · Ensure that medical personnel are aware of the material(s) involved, take precautions to protect themselves and avoid contamination. · Move victim to fresh air if it can be done safely. · Administer oxygen if breathing is difficult. · If victim is not breathing: -- DO NOT perform mouth-to-mouth resuscitation; the victim may have ingested or inhaled the substance. -- If equipped and pulse detected, wash face and mouth, then give artificial respiration using a proper respiratory medical device (bag-valve mask, pocket mask equipped…[7]
  • Fresh air, rest. Half-upright position. Refer immediately for medical attention.[3]
  • First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer immediately for medical attention.[3]

Storage

  • Provision to contain effluent from fire extinguishing. Fireproof. Separated from strong oxidants, strong acids and food and feedstuffs. Dry. Well closed. Store in an area without drain or sewer access.[3]
  • Outside or detached storage is prefered. Avoid oxidizing material, acids, and sources of halogen. Store in a cool, dry, well-ventilated location.[4]

Incompatibilities

  • Violent reaction with oxidizers and mercury, strong acids, organic anhydrides, isocyanates, aldehydes, nitroparrafins, halogenated hydrocarbons, alcohols and many other compounds. Attacks many metals and alloys, especially copper. Aqueous solutions may attack glass.[4]
  • Incompatible with triethynyl aluminum[4]
