Health.
Exposure effects
May cause cancer.
   Ingestion
Irritation of the gastrointestinal tract is likely after exposure to morpholine. The amount of irritation is dependent upon the concentration.
   Inhalation
Cough and nasal irritation have been seen in humans exposed to 1200 ppm for about 1.5 Minutes.
   Skin
Skin contact represents a moderate degree of hazard, which decreases as the concentration decreases to 25% or less in water.

First aid
 
   Ingestion
Seek medical assistance immediately.
   Inhalation
Move victim to fresh air. Administer oxygen if having problem breathing.
   Skin
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.
   Eyes
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
