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.
Foam, alcohol-resistant foam, dry powder, water spray, carbon dioxide.
EXPLOSION Above 52°C explosive vapour/air mixtures may be formed.
Above 52°C use a closed system, ventilation, and explosion-proof electrical equipment.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
STRICT HYGIENE!

•INHALATION Cough. Laboured breathing. Sore throat.
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.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
•EYES Blurred vision. 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.

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID .

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on burning producing toxic fumes of nitrogen oxides. The solution in water is a medium strong base. Reacts with oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK not established.


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

INHALATION RISK:
A harmful concentration of airborne particles can be reached quickly on spraying.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Boiling point: 142-150°C
Relative density (water = 1): 0.85
Solubility in water: very good
Vapour pressure, kPa at 20°C: 0.6
Relative vapour density (air = 1): 3
Relative density of the vapour/air-mixture at 20°C (air = 1): 1
Flash point:
52°C o.c.

ENVIRONMENTAL
DATA


N O T E S

Explosive limits are unknown in literature, although the substance is combustible and has a flash point < 61°C. Health effects of exposure to the substance have not been investigated adequately. Insufficient data are available on the effect of this substance on environment, therefore utmost care must be taken.
