TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Not combustible. Liquid formulations containing organic solvents may be flammable.

In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION


EXPOSURE
AVOID EXPOSURE OF (PREGNANT) WOMEN!
IN ALL CASES CONSULT A DOCTOR!
•INHALATION
Local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention.
•SKIN
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
•EYES
Safety spectacles.
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. Wash hands before eating.
Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALLINE POWDER

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating producing toxic and corrosive fumes (hydrogen chloride - see ICSC0163, nitrogen oxides, cyanides).

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.


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

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

EFFECTS OF SHORT-TERM EXPOSURE:


EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Animal tests show that this substance possibly causes malformations in human babies.

PHYSICAL
PROPERTIES

Melting point: 168°C
Density: 1.26
g/cm3
Solubility in water, g/100 ml at 25°C: 0.02
Vapour pressure, Pa at 20°C:
negligible
Octanol/water partition coefficient as log Pow: 2.24

ENVIRONMENTAL
DATA

The substance is toxic to aquatic organisms. 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

If the substance is formulated with solvents also consult the ICSCs of these materials. Carrier solvents used in commercial formulations may change physical and toxicological properties. Bladex is a trade name. Card has been partly updated in October 2005. See section Emergency Response.
Transport Emergency Card: TEC (R)-61GT7-III
