TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO contact with oxidants.
In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION


EXPOSURE
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
•INHALATION (See Ingestion).
Local exhaust or breathing protection.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
•SKIN
Protective gloves.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
•EYES
Safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION Convulsions. Muscle stiffness. Shock or collapse.
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Refer for medical attention. Keep victim completely undisturbed.

PHYSICAL STATE; APPEARANCE:
ODOURLESS AND COLOURLESS CRYSTALS, WITH BITTER TASTE.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating producing toxic fumes including nitrogen oxides . The substance is a weak base. Reacts with strong oxidants, causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
OSHA PEL: TWA 0.15 mg/m3
NIOSH REL: TWA 0.15 mg/m3
NIOSH IDLH: 3 mg/m3 See: 57249
TLV: 0.15 mg/m3 as TWA; (ACGIH 2004).
MAK: IIb (not established but data is available) (DFG 2004).


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

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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the central nervous system , resulting in convulsions, muscle contractions, respiratory failure. Exposure may result in death.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Decomposes below boiling point
Melting point: 275-285°C
Density: 1.36
g/cm3
Solubility in water:
none
Octanol/water partition coefficient as log Pow: 1.68

ENVIRONMENTAL
DATA

The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment; special attention should be given to birds. This substance does enter the environment under normal use. Great care, however, should be given to avoid any additional release, e.g. through inappropriate disposal.

N O T E S

Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Card has been partly updated in April 2005. See sections Occupational Exposure Limits, Emergency Response.
Transport Emergency Card: TEC (R)-61GT2-I
