TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Flammable.
NO open flames, NO sparks, and NO smoking. NO contact with strong oxidants.
AFFF, alcohol-resistant foam, powder, carbon dioxide.
EXPLOSION Above 25°C explosive vapour/air mixtures may be formed. Risk of fire and explosion on contact with strong oxidants.
Above 25°C use a closed system, ventilation, and explosion-proof electrical equipment.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT GENERATION OF MISTS!

 •INHALATION Cough. Nausea. Sore throat.
Ventilation.
Fresh air, rest.
 •SKIN
Protective gloves.
Rinse and then wash skin with water and soap.
 •EYES Redness. Pain.
Safety goggles.
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. 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. (Extra personal protection: filter respirator for organic gases and vapours.)
Fireproof. Separated from strong oxidants. Cool. Well closed.

UN Hazard Class: 3
UN Packing Group: III
ICSC: 1022 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 and may travel along the ground; distant ignition possible.

CHEMICAL DANGERS:
Reacts violently with strong oxidants causing fire and explosion hazard. Attacks many plastics and resins.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK not established.


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

INHALATION RISK:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying.

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

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Boiling point: 126°C
Melting point: -43°C

Vapour pressure, kPa at 20°C: 1.1
Relative vapour density (air = 1): 4.07
Flash point: 25°C c.c.
Auto-ignition temperature: 445°C
Explosive limits, vol% in air: 1.4-11.0
