	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Flammable. Above 40°C explosive vapour/air mixtures may be formed.	NO open flames, NO sparks and NO smoking. Above 40°C use a closed system, ventilation and explosion-proof electrical equipment.	Use water spray, alcohol-resistant foam, powder, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

PREVENT GENERATION OF MISTS!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Dizziness. Headache. Drowsiness. Nausea. Unconsciousness.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	Dry skin.	Protective gloves.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes	Redness.	Wear safety goggles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion	Cough. Diarrhoea. Sore throat. Vomiting. Further see Inhalation.	Do not eat, drink, or smoke during work.	Do NOT induce vomiting. Refer for medical attention . See Notes.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
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. Do NOT wash away into sewer. Personal protection: filter respirator for organic vapours of low boiling point adapted to the airborne concentration of the substance.	According to UN GHS Criteria Transportation UN Classification UN Hazard Class: 3; UN Pack Group: III
STORAGE
Fireproof. Separated from strong oxidants. Well closed.

Physical dangers

Chemical dangers
Reacts with strong oxidants. This generates fire and explosion hazard.

Boiling point: 155-217°C
Melting point: <0°C
Density: 0.76-0.79 g/cm³
Solubility in water: none
Vapour pressure, kPa at 20°C: 0.1-0.3
Flash point: 40-62°C c.c.
Auto-ignition temperature: 255-270°C
Explosive limits, vol% in air: 0.7-6.0

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its vapour and by ingestion. Effects of short-term exposure The vapour is mildly irritating to the eyes. The substance may cause effects on the central nervous system. Exposure to high concentrations of vapour could cause unconsciousness. If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis.	Inhalation risk No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C. Effects of long-term or repeated exposure The substance defats the skin, which may cause dryness or cracking. See Notes.

OCCUPATIONAL EXPOSURE LIMITS
MAK: 300 mg/m³, 50 ppm; peak limitation category: II(2); pregnancy risk group: D

ENVIRONMENT
The substance is toxic to aquatic organisms.

NOTES
This is a mixture of C9-C13 naphthenes, iso- and n-paraffins. Neither the concentration of aromatics nor of hexane is greater than 0.1% by volume. Note P: the EU classification as carcinogen (R45) does not apply if it can be shown that the benzene content is below 0.1% by volume. Depending on the raw material and the production processes, the composition and physical properties of this solvent can vary considerably. The symptoms of chemical pneumonitis do not become manifest until a few hours or even a few days have passed.
