TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Combustible.
NO open flames.
Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION Above 96°C explosive vapour/air mixtures may be formed.
Above 96°C use a closed system, ventilation.

EXPOSURE


•INHALATION
Ventilation.
Fresh air, rest.
•SKIN Dry skin.
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
•EYES Redness.
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.

ICSC: 0039 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

PHYSICAL STATE; APPEARANCE:
HYGROSCOPIC COLOURLESS LIQUID.

PHYSICAL DANGERS:


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

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: 50 mg/m3 (Inhalable fraction)
Peak limitation category: I(2) Pregnancy risk group: C
(DFG 2006).


ROUTES OF EXPOSURE:


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:
The substance is mildly irritating to the eyes .

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