	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Flammable. Above 51°C explosive vapour/air mixtures may be formed.	NO open flames, NO sparks and NO smoking. Above 51°C use a closed system and ventilation.	Use water spray, powder, foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

AVOID ALL CONTACT!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Shortness of breath.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest.
Skin	MAY BE ABSORBED! Redness.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes	Redness. Pain.	Wear safety spectacles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion	Burning sensation.	Do not eat, drink, or smoke during work.	Rinse mouth. Give one or two glasses of water to drink.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Remove all ignition sources. Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.	According to UN GHS Criteria Transportation UN Classification UN Hazard Class: 3; UN Pack Group: III
STORAGE
Fireproof. Separated from strong oxidants.

Physical dangers

Chemical dangers
The substance can presumably form explosive peroxides. Reacts violently with strong oxidants.

Formula: C₆H₁₄O₃ / (CH₃OCH₂CH₂)₂O
Molecular mass: 134.2
Boiling point: 162°C
Melting point: -68°C
Relative density (water = 1): 0.95
Solubility in water: miscible
Vapour pressure, kPa at 20°C: 0.33
Relative vapour density (air = 1): 4.6
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.01
Flash point: 51°C c.c.
Auto-ignition temperature: 190°C
Explosive limits, vol% in air: 1.5-17.4
Octanol/water partition coefficient as log Pow: -0.36

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its vapour, by ingestion and through the skin. Effects of short-term exposure The substance is mildly irritating to the eyes, skin and respiratory tract.	Inhalation risk A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C. Effects of long-term or repeated exposure Animal tests show that this substance possibly causes toxicity to human reproduction or development.
