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 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.

SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Collect leaking liquid in sealable containers. Then wash away with plenty of water.
Separated from strong oxidants.

PHYSICAL STATE; APPEARANCE:
HYGROSCOPIC LIQUID OR CRYSTALS , WITH CHARACTERISTIC ODOUR. TURNS BROWN ON EXPOSURE TO AIR AND LIGHT.

PHYSICAL DANGERS:
The vapour is heavier than air.

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic and corrosive fumes including nitrogen oxides. The substance is a weak base. Reacts with oxidants.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV: ppm; 5 mg/m3 (ACGIH 1993-1994).


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion.

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 irritates the eyes, the skin and the respiratory tract.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization.
