Combustible. Above 93°C explosive vapour/air mixtures may be formed.
NO open flames. Above 93°C use a closed system and ventilation.
Use water spray, powder, alcohol-resistant foam, carbon dioxide.
PREVENT GENERATION OF MISTS! AVOID EXPOSURE OF (PREGNANT) WOMEN!
Fresh air, rest.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
Wear safety spectacles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Do not eat, drink, or smoke during work.
CLASSIFICATION & LABELLING

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS LIQUID.
Chemical dangers The substance can presumably form explosive peroxides. Reacts with strong oxidants.
Formula: C5H12O3 / CH3O(CH2)2O(CH2)2OH
Molecular mass: 120.2
Boiling point: 193°C Relative density (water = 1): 1.04 Solubility in water: very good Vapour pressure, Pa at 20°C: 30 Relative vapour density (air = 1): 4.1 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.001 Flash point: 93°C o.c. Auto-ignition temperature: 215°C Explosive limits, vol% in air: 1.6-18.1 Octanol/water partition coefficient as log Pow: -1.14/-0.93 (calculated)
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
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. Animal tests show that this substance possibly causes toxicity to human reproduction or development.
OCCUPATIONAL EXPOSURE LIMITS
EU-OEL: 50.1 mg/m3, 10 ppm as TWA; (skin)
Check for peroxides prior to distillation; eliminate if found.
