First Aid Measures

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.

Handling and Storage

Storage
Keep in a tightly closed container in a cool, dry location. Store only with compatible chemicals.
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.

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.

Exposure Controls/Personal Protection

Personal Protection
Use chemical protective gloves and safety goggles.
Respirators
Use a NIOSH/MSHA approved SCBA.
Exposure Effects
May cause cancer.

Fire Fighting Measures

Flash Point
154
Fire Fighting
Extinguish fire using carbon dioxide, dry chemical powder, or water spray. Use a NIOSH/MSHA approved SCBA and ful protective equipment.

Accidental Release Measures

Small spills/leaks
Evacuate area. Use recommending protective equipment. Sweep up and place in an appropriate container. Hold for disposal. Wash contaminated surfaces to remove any residue.

Stability and Reactivity

Incompatibilities
Acid halides and acid anhydrides.
Stability
Stable at normal temperatures and pressures.
