EXPOSURE


 •INHALATION
Ventilation. Local exhaust.
Fresh air, rest.
 •SKIN Dry skin.
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
 •EYES Redness. Pain.
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:
TLV not established.
EU OEL: 10 ppm, 67.5 mg/m³ as TWA; 15 ppm, 101.2 mg/m³ as STEL (EU 2006).


ROUTES OF EXPOSURE:


INHALATION RISK:
A harmful contamination of the air will be reached slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes .

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin.
