TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Highly 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	Vapour/air mixtures are explosive.	Closed system, ventilation, explosion-proof electrical equipment and lighting.	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	Corrosive. Burning sensation. Cough. Shortness of breath. Symptoms may be delayed (see Notes).	Closed system and ventilation.	Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention.
SKIN	Corrosive. Pain. Blisters.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
EYES	Corrosive. 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	Corrosive. Abdominal pain. Burning sensation. Shock or collapse.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Give plenty of water to drink. Refer for medical attention.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Collect leaking liquid in sealable containers. Cautiously neutralize spilled liquid. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Then wash away with plenty of water (extra personal protection: complete protective clothing including self-contained breathing apparatus).

Fireproof. Separated from strong oxidants, strong acids.

Unbreakable packaging; put breakable packaging into closed unbreakable container.
UN Hazard Class: 3
UN Packing Group: II

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

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

CHEMICAL DANGERS:
On combustion, forms toxic and corrosive gases including carbon monoxide and nitrogen oxides. The solution in water is a medium strong base. Reacts violently with oxidants.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV not established.
MAK: 5 ppm; 15 mg/m³; skin (1993).

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

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

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

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL

Boiling point: 68-69°C
Melting point: -85°C
Relative density (water = 1): 0.7
Solubility in water: miscible
Vapour pressure, kPa at 18.8°C: 13.3
Relative vapour density (air = 1): 2.5

Relative density of the vapour/air-mixture at 20°C (air = 1): 1.2
Flash point: -9.0°C c.c.
Auto-ignition temperature: 378°C
Explosive limits, vol% in air: 2-12
Octanol/water partition coefficient as log Pow: 0.79-0.88

ENVIRONMENTAL
DATA

N O T E S

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 spray, by a doctor or a person authorized by him/her, should be considered.
