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 42.2C explosive vapour/air mixtures may be formed.
Above 42.2C 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 Sore throat. 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 may be needed. Refer for medical attention.
Skin Redness. Pain. Skin burns.
Protective gloves. Protective clothing.
First rinse with plenty of water, then remove contaminated clothes and rinse again. Refer for medical attention.
Eyes Redness. Pain. 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 Burning sensation. Abdominal pain. Shock or collapse.
Do not eat, drink, or smoke during work.
Rinse mouth. Give plenty of water to drink. Do NOT induce vomiting. Refer for medical attention.

N,N-DIMETHYLCYCLOHEXYLAMINE ICSC: 1444
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic fumes including nitrogen oxides. The substance is a medium strong base.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

INHALATION RISK:
No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20C.

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

PHYSICAL PROPERTIES
Boiling point: 162-165C
Melting point: -60C
Relative density (water = 1) : 0.85
Solubility in water, g/100 ml: 20
Vapour pressure, kPa at 25C: 0.4
Relative vapour density (air = 1): 4.4
Relative density of the vapour/air-mixture at 20C (air = 1): 1.01
Flash point: 42.2C c.c.
Auto-ignition temperature: 215C
Explosive limits, vol% in air: 3.6-19
Octanol/water partition coefficient as log Pow: 2.01
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms.
NOTES
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 is therefore essential. Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
