TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Flammable. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames, NO sparks, and NO smoking.	Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION	Above 35°C explosive vapour/air mixtures may be formed.	Above 35°C use a closed system, ventilation, and explosion-proof electrical equipment.	In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE		PREVENT GENERATION OF MISTS! AVOID ALL CONTACT!	IN ALL CASES CONSULT A DOCTOR!
Inhalation	Burning sensation. Cough. Laboured breathing. Shortness of breath. Symptoms may be delayed (see Notes).	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention. See Notes.
Skin	MAY BE ABSORBED! Redness. Pain. Skin burns. Blisters.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
Eyes	Redness. Pain. Blurred vision. Severe deep burns.	Face shield or eye protection in combination with breathing protection.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion	Abdominal pain. Burning sensation. Cough. Diarrhoea. Nausea. Shock or collapse. Vomiting.	Do not eat, drink, or smoke during work.	Rinse mouth. Give plenty of water to drink. Do NOT induce vomiting. Refer for medical attention.

SPILLAGE DISPOSAL

PACKAGING & LABELLING

MORPHOLINE

ICSC: 0302

IMPORTANT DATA

PHYSICAL STATE; APPEARANCE:
COLOURLESS HYGROSCOPIC LIQUID, WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic fumes (nitrogen oxides, carbon monoxide). The substance is a medium strong base. Reacts with strong oxidants causing fire hazard. Attacks plastics, rubber and coatings. Unstable if stored in copper or zinc containers.

OCCUPATIONAL EXPOSURE LIMITS:
TLV (as TWA): 20 ppm; mg/m^3 (A4 skin) (ACGIH 1999). MAK: 10 ppm; 36 mg/m^3; I, IIc (1999).

ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

INHALATION RISK:
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. Inhalation of vapour of the substance may cause lung oedema (see Notes).

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the liver and kidneys.

PHYSICAL PROPERTIES

Boiling point: 129°C
Melting point: -5°C
Relative density (water = 1): 1.0
Solubility in water: miscible
Vapour pressure, kPa at 20°C: 1.06
Relative vapour density (air = 1): 3.00

Relative density of the vapour/air-mixture at 20°C (air = 1): 1.01
Flash point: 35°C c.c.
Auto-ignition temperature: 310°C
Explosive limits, vol% in air: 1.4-11.2
Octanol/water partition coefficient as log Pow: -0.86

ENVIRONMENTAL DATA

NOTES

Depending on the degree of exposure, periodic medical examination is indicated. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Immediate administration of an appropriate inhalation therapy (e.g. spray), by a doctor or a person authorized by him/her, should be considered.
