TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Not combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.

In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION Risk of fire and explosion if formulations contain flammable/explosive solvents.

In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT DISPERSION OF DUST! STRICT HYGIENE!

•INHALATION see Ingestion.
Avoid inhalation of fine dust and mist. Local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention.
•SKIN MAY BE ABSORBED! See Ingestion.
Protective gloves. Protective clothing.
Wear protective gloves when administering first aid. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
•EYES Redness.
Face shield or eye protection in combination with breathing protection.
First rinse with plenty of water (remove contact lenses if easily possible). Refer for medical attention.
•INGESTION Convulsions. Nausea. Dizziness. Headache. Hypersalivation Diarrhoea. Vomiting.
Do not eat, drink, or smoke during work. Wash hands before eating.
Refer immediately for medical attention. Do NOT induce vomiting. Rinse mouth. Give a slurry of activated charcoal in water to drink. Rest.

PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALLINE POWDER .

PHYSICAL DANGERS:


CHEMICAL DANGERS:
On contact with hot surfaces or flames this substance decomposes forming toxic and corrosive fumes. The substance decomposes on contact with bases , producing trichlorobenzene , and on contact with powdered metals.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.5 mg/m3 as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2006).
MAK: 0.1 mg/m3; (Inhalable fraction)
Peak limitation category: II(8);
skin absorption (H);
Carcinogen category: 4; Pregnancy risk group: C; BAT issued;
(DFG 2006).
OSHA PEL: TWA 0.5 mg/m3 skin
NIOSH REL: TWA 0.5 mg/m3 skin
NIOSH IDLH: 50 mg/m3 See: 58899


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

INHALATION RISK:
A harmful concentration of airborne particles can be reached quicklywhen dispersed.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the central nervous system , resulting in convulsions. Exposure may result in death. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the liver. Tumours have been detected in experimental animals but may not be relevant to humans.

PHYSICAL
PROPERTIES

Boiling point: 323°C
Melting point: 113°C
Relative density (water = 1): 1.87
Solubility in water, g/100 ml at 20°C: 0.0007
Vapour pressure, Pa at 20°C: 0.0012

ENVIRONMENTAL
DATA

The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish. 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

Depending on the degree of exposure, periodic medical examination is suggested. Carrier solvents used in commercial formulations may change physical and toxicological properties. Do NOT take working clothes home.
