  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Flammable.  Above 29°C explosive vapour/air mixtures may be formed.  NO open flames, NO sparks and NO smoking.  Above 29°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 Cough. Shortness of breath. Euphoria. Headache. Dizziness. Drowsiness. Unconsciousness.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Dry skin. Redness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
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 Sore throat. Nausea. Vomiting. Abdominal pain. 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
Personal protection: filter respirator for organic vapours of low boiling point adapted to the airborne concentration of the substance. Ventilation. Do NOT wash away into sewer. 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.

PACKAGING
 
MEDIUM ALIPHATIC SOLVENT NAPHTHA (PETROLEUM) (OBSOLETE) ICSC: 1381
PHYSICAL & CHEMICAL INFORMATION

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
Reacts with strong oxidants. This generates fire and explosion hazard. Attacks some forms of plastic and rubber. 


Boiling point: 138-220°C
Melting point: -48 - -26°C
Density: 0.77-0.82 g/cm³
Solubility in water: none
Vapour pressure, kPa at 20°C: 0.2-0.6
Relative vapour density (air = 1): 4.0
Flash point: 29-70°C c.c.
Auto-ignition temperature: 220-250°C
Explosive limits, vol% in air: 0.6-6.5
Viscosity: 1 - 4.3  


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 and respiratory tract. 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
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster. 

Effects of long-term or repeated exposure
The substance defats the skin, which may cause dryness or cracking. The substance may have effects on the central nervous system and liver. This may result in impaired functions. See Notes. 


OCCUPATIONAL EXPOSURE LIMITS
 

ENVIRONMENT
Environmental effects from the substance have not been investigated adequately. 

NOTES
The contents of benzene is less than 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.
See ICSC 0361.
Work clothes saturated with oxygen may be a serious fire hazard.
