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: · 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…[10]
(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: Soap wash immediately - If this chemical contacts the skin, immediately wash the contaminated skin with soap and water.[5]
Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.[3]

Storage

Fireproof. Separated from incompatible materials and food and feedstuffs. See Chemical Dangers.[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. Storage class (TRGS 510): Flammable liquids.[6]
Avoid oxidizing materials, acids, and sources of halogens. Store in cool, dry, well-ventilated location.[6]

Incompatibilities

Incompatible materials: Strong oxidizing agents.[6]
Toxic gases and vapors (such as oxides of nitrogen and carbon monoxide) may be released in fire involving triethylamine.[6]
Contact with strong acids may cause violent spattering.[6]
The complex, containing excess (dinitrogen tetraoxide) over ... (triethylamine), exploded at below 0 °C when free of solvent.[6]
