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, water spray, foam, carbon dioxide.
EXPLOSION	Above 28°C explosive vapour/air mixtures may be formed.	Above 28°C use a closed system, ventilation, and explosion-proof electrical equipment.	In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE		AVOID ALL CONTACT!
INHALATION	Sore throat. Cough. Burning sensation. 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.
SKIN	MAY BE ABSORBED! Pain. Blisters. Delayed effects.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower. 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 cramps. Shock or collapse.		Rinse mouth. Do NOT induce vomiting. Refer for medical attention.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Evacuate danger area! Consult an expert! Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer (extra personal protection: complete protective clothing including self-contained breathing apparatus).

Fireproof. Separated from strong oxidants, food and feedstuffs. Keep in the dark. Store only if stabilized.

Unbreakable packaging; put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs.
UN Hazard Class: 6.1
UN Subsidiary Risks: 3 and 8
UN Packing Group: 1

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID , WITH PUNGENT ODOUR. TURNS DARK AND RESINIFIES ON PROLONGED EXPOSURE TO LIGHT.

PHYSICAL DANGERS:

CHEMICAL DANGERS:
The substance polymerizes slowly under the influence of light. The substance decomposes on heating or on burning producing toxic and corrosive fumes including hydrogen chloride and phosgene. Reacts with strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV: 1 ppm; 3.8 mg/m³ C (skin) (ACGIH 1995-1996).

ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin, by ingestion and , also as a vapour!

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. Tear drawing. The substance is corrosive to the eyes, the skin and the respiratory tract. Inhalation of the vapour of this substance may cause lung oedema (see Notes). The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Boiling point: 120°C
Melting point: -45°C
Relative density (water = 1): 1.1
Solubility in water, g/100 ml at 20°C: 10
Vapour pressure, kPa at 25°C: 1.5

Relative vapour density (air = 1): 3.7
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.03
Flash point: 28°C c.c.
Octanol/water partition coefficient as log Pow: 0.28

ENVIRONMENTAL
DATA

N O T E S

Explosive limits are unknown in literature, although the substance is combustible and has a flash point <55°C. 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. An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert. The odour warning when the exposure limit value is exceeded is insufficient.
