TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION     In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   PREVENT DISPERSION OF DUST! STRICT HYGIENE!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Cough. Sore throat. See Ingestion.  Use 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. Pain. Further see Inhalation.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Pain.  Wear safety goggles or face shield.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Fever. Sweating. Incoordination. Shortness of breath. Laboured breathing. Weakness. Headache. Nausea. Vomiting. Abdominal pain. Dizziness. Drowsiness.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Give one or two glasses of water to drink. Refer for medical attention .

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces toxic and corrosive fumes including hydrogen chloride and dioxins. Reacts with strong oxidants. This generates fire and explosion hazard. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

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, especially if powdered. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. Inhalation may cause lung oedema. See Notes. The substance may cause effects on the cardiovascular system and central nervous system. Exposure at high levels could cause unconsciousness and death. The effects may be delayed. Medical observation is indicated. 

Effects of long-term or repeated exposure
May cause chloracne. The substance may have effects on the central nervous system, kidneys and liver. Tumours have been detected in experimental animals but may not be relevant to humans. See Notes. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Solubility in water, g/100ml at 25°C: 33   The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. Avoid release to the environment in circumstances different to normal use. 

NOTES
Humans are generally exposed to technical grade of the substance which usually contain toxic microcontaminants such as polychlorinated dibenzodioxins and dibenzofurans.
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort.
Rest and medical observation is therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
Do NOT take working clothes home.
Also consult ICSC 0069 (Pentachlorophenol).
Card has been partly updated in October 2004.
