  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible.  Above 64°C explosive vapour/air mixtures may be formed.  NO open flames.  Above 64°C use a closed system, ventilation and explosion-proof electrical equipment.  Use water spray, powder, foam, carbon dioxide.   

 STRICT HYGIENE!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Dizziness. Shortness of breath. Sore throat. Unconsciousness. Weakness.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Refer for medical attention. 
Skin MAY BE ABSORBED! Dry skin. Redness. Roughness. Skin burns. Pain. Blisters.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Pain. Blurred vision.  Wear 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 refer for medical attention. 
Ingestion Nausea. Vomiting.  Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Collect leaking and spilled liquid in sealable containers as far as possible. Wash away remainder with plenty of water.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS LIQUID WITH PUNGENT ODOUR. 

Physical dangers
 

Chemical dangers
The substance can presumably form explosive peroxides. May explode on heating. Reacts with strong oxidants. 

Formula: C6H10O3 / C2H3OCH2OCH2C2H3O
Molecular mass: 130.2
Boiling point at 100kPa: 260°C
Relative density (water = 1): 1.26
Solubility in water: see Notes
Vapour pressure, Pa at 25°C: 12
Relative vapour density (air = 1): 4.5
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.00
Flash point: 64°C
Explosive limits, vol% in air: see Notes 


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation, through the skin and by ingestion. 

Effects of short-term exposure
The substance is severely irritating to the eyes, skin and respiratory tract. Inhalation of the vapour may cause lung oedema. See Notes. The substance may cause effects on the blood, kidneys, liver and testes. Exposure could cause lowering of consciousness. Medical observation is indicated. 

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
Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. Animal tests show that this substance possibly causes toxic effects upon human reproduction. 


Occupational exposure limits
TLV: 0.01 ppm as TWA; A4 (not classifiable as a human carcinogen).
MAK: skin absorption (H); carcinogen category: 3B 

ENVIRONMENT
 

NOTES
The auto-ignition temperature is unknown in the literature.
Explosive limits are unknown in the literature.
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 inhalation therapy by a doctor, or by an authorized person, should be considered.
The odour warning when the exposure limit value is exceeded is insufficient.
Check for peroxides prior to distillation; eliminate if found.
