TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames.  Use foam, dry powder, carbon dioxide. 
EXPLOSION      
 
EXPOSURE See Notes.  PREVENT DISPERSION OF DUST!   
Inhalation   Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin   Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes   Wear safety goggles or eye protection in combination with breathing protection if powder.  Rinse with plenty of water (remove contact lenses if easily possible). 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. 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 transport with food and feedstuffs. 
EC Classification
 
UN Classification
UN Hazard Class: 6.1; UN Pack Group: III 
GHS Classification

EMERGENCY RESPONSE SAFE STORAGE
  Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing. Separated from strong oxidants and food and feedstuffs. 

IMPORTANT DATA
Physical State; Appearance
COLOURLESS CRYSTALS WITH CHARACTERISTIC ODOUR. 

Physical dangers
No data. 

Chemical dangers
Decomposes on heating and on contact with strong oxidants. This produces toxic and corrosive fumes including hydrogen chloride. Decomposes on burning. This produces toxic and corrosive fumes including hydrogen chloride. The substance is a weak acid. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK (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. 

Effects of short-term exposure
See Notes. 

Effects of long-term or repeated exposure
See Notes. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 248-253°C
Melting point: 62°C
Solubility in water: poor
Relative vapour density (air = 1): 6.8
Octanol/water partition coefficient as log Pow: 3.8  
The substance is 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 taken to avoid any additional release, for example through inappropriate disposal. 

NOTES
Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
No data are available on this isomer but a mixture of trichlorophenols may cause irritation of the skin, eyes and respiratory tract.
These substances may cause acute metabolic effects resulting in damage in several organs notably CNS.
Some technical products may contain highly toxic impurities including polychlorinated dibenzo-p-dioxins and furans.
Depending on the degree of exposure, periodic medical examination is suggested.
