EXPOSURE
PREVENT GENERATION OF MISTS! AVOID EXPOSURE OF (PREGNANT) WOMEN!

 •INHALATION
Ventilation.
Fresh air, rest.
 •SKIN Dry skin.
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
 •EYES
Safety spectacles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
 •INGESTION
Do not eat, drink, or smoke during work.
Rinse mouth.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Collect leaking and spilled liquid in sealable containers as far as possible. Wash away remainder with plenty of water.
Separated from strong oxidants. Ventilation along the floor.

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance can presumably form explosive peroxides. Reacts with strong oxidants .

OCCUPATIONAL EXPOSURE LIMITS:
EU OEL: 50.1 mg/m³ 10 ppm as TWA (skin) (EU 2006).


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

INHALATION RISK:
No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:


EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin. Animal tests show that this substance possibly causes toxicity to human reproduction or development.
