TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE 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      
 
EXPOSURE      
Inhalation   Avoid inhalation of dust and mist.  Fresh air, rest. 
Skin   Protective gloves.  Rinse skin with plenty of water or shower. 
Eyes   Wear safety spectacles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work. Wash hands before eating.   

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT wash away into sewer.  Do not transport with food and feedstuffs.

IMPORTANT DATA
Physical State; Appearance
COLOURLESS SOLID OR WHITE POWDER. 

Physical dangers
No data. 

Chemical dangers
Decomposes on burning. This produces toxic and corrosive fumes including nitrogen oxides, hydrogen chloride and hydrogen fluoride. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
The substance can be absorbed into the body by inhalation. 

Inhalation risk
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered. 

Effects of short-term exposure
 

Effects of long-term or repeated exposure
The substance may have effects on the blood. This may result in formation of methaemoglobin. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: 202-205°C
Relative density (water = 1): 1.7
Solubility in water, g/100ml: <0.1 (none)
Vapour pressure at 25°C: negligible
Octanol/water partition coefficient as log Pow: 5.68  
The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish. The substance may cause long-term effects in the aquatic environment. Avoid release to the environment in circumstances different to normal use. 

NOTES
If the substance is formulated with solvent(s) also consult the card(s) (ICSC) of the solvent(s).
Carrier solvents used in commercial formulations may change physical and toxicological properties.
Consult, Hexafluron, Trueno are trade names.
