TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Combustible.
NO open flames.
Powder, water spray, foam, carbon dioxide.
EXPLOSION Above 70°C explosive vapour/air mixtures may be formed.
Above 70°C use a closed system, ventilation.

EXPOSURE
PREVENT GENERATION OF MISTS!

•INHALATION Cough. Sore throat.
Ventilation.
Fresh air, rest.
•SKIN Redness.
Protective gloves.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
•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. Give one or two glasses of water to drink. Rest.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Wash away remainder with plenty of water.
Separated from strong oxidants. Ventilation along the floor. Well closed.

ICSC: 1024 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:
COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
The vapour is heavier than air.

CHEMICAL DANGERS:
Reacts with strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: IIb (not established but data is available) (DFG 2008).


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation.

INHALATION RISK:
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C ; on spraying or dispersing, however, much faster .

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes, the skin and the respiratory tract.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
