TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames.  Use water spray, powder, foam, carbon dioxide. 
EXPLOSION     In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation Confusion. Convulsions. Cough. Dizziness. Headache. Nausea. Vomiting. Weakness. Confusion.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety spectacles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal pain. Diarrhoea. 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. Refer for medical attention .

IMPORTANT DATA
Physical State; Appearance
COLOURLESS CRYSTALS. 

Physical dangers
 

Chemical dangers
Decomposes on burning. Decomposes on contact with acids. This produces toxic and corrosive fumes including hydrogen chloride. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol, 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, especially if powdered. 

Effects of short-term exposure
The substance is irritating to the eyes and skin (technical grade). The substance may cause effects on the central nervous system, liver and kidneys. 

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: 77-78°C
Density: 1.13 g/cm³
Solubility in water: none
Flash point: 193°C o.c.
Octanol/water partition coefficient as log Pow: 4.28  
The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish. 

NOTES
The appearance and physical properties of technical products can differ from those of the pure substance.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
Acarin, Carbax, Kelthane and Mitigan are trade names.
