TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Combustible. Gives off irritating or toxic fumes (or gases) in a fire.	NO contact with oxidants. NO open flames.	Powder, water spray, foam, carbon dioxide.
EXPLOSION	Above 77°C explosive vapour/air mixtures may be formed.	Above 77°C use a closed system, ventilation. Prevent build-up of electrostatic charges (e.g., by grounding).	In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE
Inhalation	Cough. Dizziness. Headache. Nausea. Vomiting. Weakness.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	Redness. Pain.	Protective gloves.	Rinse skin with plenty of water or shower. Remove contaminated clothes.
Eyes	Pain. Redness. Blurred vision.	Safety spectacles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion	Abdominal pain. (See Inhalation).	Do not eat, drink, or smoke during work.	Do NOT induce vomiting. Give plenty of water to drink. Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Ventilation. Collect leaking liquid in covered containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT let this chemical enter the environment. Chemical protection suit.	Xi Symbol N Symbol R: 19-36/38-51/53 S: (2-)26-28-61

EMERGENCY RESPONSE	SAFE STORAGE
NFPA Code: H1; F2; R0	Separated from strong oxidants. Keep in a well-ventilated room. Well closed to reduce rate of peroxide formation.

IMPORTANT DATA

Physical State; Appearance
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

Physical dangers
As a result of flow, agitation, etc., electrostatic charges can be generated.

Chemical dangers
The substance can form explosive peroxides. The substance decomposes on heating producing irritating fumes. Reacts strongly with oxidants.

Occupational exposure limits
TLV not established.
MAK not established.

Inhalation risk
A harmful contamination of the air will will not or will only very slowly be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.

Effects of short-term exposure
The substance is irritating to the eyes, the skin and the respiratory tract. The substance may cause effects on the central nervous system. If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis.

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the kidneys.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: 207.6°C Melting point: -35.8°C Relative density (water = 1): 0.9702 Solubility in water: very poor Vapour pressure, kPa at 25°C: 0.05 Relative vapour density (air = 1): 4.6 Flash point: 77°C o.c. Auto-ignition temperature: 385°C Explosive limits, vol% in air: 0.8 (at 100°C)-5.0 (at 150°C) Octanol/water partition coefficient as log Pow: 3.78	The substance is toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish. It is strongly advised that this substance does not enter the environment.

NOTES

Check for peroxides prior to distillation; eliminate if found.
