PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID.

PHYSICAL DANGERS:
The vapour mixes well with air, explosive mixtures are easily formed.

CHEMICAL DANGERS:
Reacts violently with oxidants causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.


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

INHALATION RISK:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes. The substance may cause effects on the immune system , resulting in aberrations of the thymus, spleen and adrenal glands.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the central and peripheral nervous system , resulting in degeneration of the nerves.
