Hazards Identification

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.

Ingestion

Irritation of the gastrointestinal tract is likely after exposure to morpholine. The amount of irritation is dependent upon the concentration.
