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
PREVENT DISPERSION OF DUST! STRICT HYGIENE! AVOID EXPOSURE OF (PREGNANT) WOMEN! AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
•INHALATION Cough. Dizziness. Drowsiness. Headache. Fever or elevated body temperature. Laboured breathing. Sore throat.
Local exhaust or breathing protection.
Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
•SKIN MAY BE ABSORBED! Redness. Blisters. (Further see Inhalation).
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention. Wear protective gloves when administering first aid.
•EYES Redness. Pain.
Safety goggles, face shield, or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION Abdominal cramps. Diarrhoea. Nausea. Unconsciousness. Vomiting. Weakness. (Further see Inhalation).
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Give a slurry of activated charcoal in water to drink. Give plenty of water to drink. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALS OR SOLID IN VARIOUS FORMS , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating above 200°C, producing toxic and corrosive fumes including dioxins . Reacts violently with strong oxidants .

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.5 mg/m3 as TWA; (skin); A3; BEI issued; (ACGIH 2003).
MAK: H;
Carcinogen category: 2;
(DFG 2002).
OSHA PEL: TWA 0.5 mg/m3 skin
NIOSH REL: TWA 0.5 mg/m3 skin
NIOSH IDLH: 2.5 mg/m3 See: 87865


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, 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 when dispersed.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes , the skin and the respiratory tract . The substance may cause effects on the cardiovascular system , resulting in cardiac disorders and heart failure.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the central nervous system , kidneys , liver , lungs , immune system , thyroid . This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development.

PHYSICAL
PROPERTIES

Boiling point (decomposes): 309°C
Melting point: 191°C
Density: 1.98
Solubility in water, g/100 ml at 20°C: 0.001
Vapour pressure, Pa at 20°C: 0.02
Relative vapour density (air = 1): 9.2
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.00
Octanol/water partition coefficient as log Pow: 5.01

ENVIRONMENTAL
DATA

The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. 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

The commercial product may contain very toxic impurities (dioxins). The odour warning when the exposure limit value is exceeded is insufficient.
