TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Water in large amounts, alcohol-resistant foam, dry powder, carbon dioxide.
EXPLOSION


EXPOSURE
PREVENT GENERATION OF MISTS!

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

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Collect leaking liquid in covered containers. Then wash away with plenty of water.

PHYSICAL STATE; APPEARANCE:
COLOURLESS VISCOUS HYGROSCOPIC LIQUID OR CRYSTALS , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:


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

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 5 mg/m3 as TWA; (ACGIH 2003).
MAK not established.
(DFG 2008).


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

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

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

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