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 in large amounts, carbon dioxide.
EXPLOSION Above 33°C explosive vapour/air mixtures may be formed.
Above 33°C closed system, ventilation, and explosion-proof electrical equipment.
In case of fire: keep drums, etc., cool by spraying with water.
 
EXPOSURE
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
INHALATION Sore throat. Cough. Burning sensation. Shortness of breath. Laboured breathing. Symptoms may be delayed (see Notes).
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Half-upright position. Artificial respiration if indicated, and refer for medical attention.
SKIN Pain. Redness. Blisters. Skin burns.
Protective gloves. Protective clothing.
Rinse skin with plenty of water or shower, and refer for medical attention.
EYES Pain. Redness. Severe deep burns. Loss of vision.
Safety goggles. 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 cramps. Shock or collapse.
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth, and refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT let this chemical enter the environment (extra personal protection: complete protective clothing including self-contained breathing apparatus).
Fireproof. Separated from food and feedstuff, strong oxidants, acids, acid anhydrides, acid chlorides. Well closed.

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

PHYSICAL DANGERS:
The vapour is heavier than air and may travel along the ground; distant ignition possible.

CHEMICAL DANGERS:
The substance decomposes on heating or on burning producing toxic fumes of nitrogen oxides. The substance is a strong base, it reacts violently with acid and is corrosive. Reacts with strong oxidants, acid anhydrides, and acid chlorides. Reacts with mercury to form shock-sensitive compounds causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
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 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. Inhalation of the vapour may cause lung oedema (see Notes). Swallowing the liquid may cause aspiration into the lungs with the risk of chemical pneumonitis. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
PHYSICAL
PROPERTIES
 Boiling point: 117-121°C
Melting point: -17°C
Relative density (water = 1): 0.9
Solubility in water: soluble
Vapour pressure, kPa at 20°C: 1.0
Relative vapour density (air = 1): 2.6 		Relative density of the vapour/air-mixture at 20°C (air = 1): 1.02
Flash point: 33°C o.c.
Auto-ignition temperature: 416°C
Explosive limits, vol% in air: 2.2-11.1
Octanol/water partition coefficient as log Pow: -1.8
ENVIRONMENTAL
DATA
 The substance is harmful to aquatic organisms.
NOTES
Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered. The symptoms of lung oedema do not become manifest until a few hours or even a few days have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential.
