TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible but enhances combustion of other substances. Many reactions may cause fire or explosion. Gives off irritating or toxic fumes (or gases) in a fire.  NO contact with flammables, combustible substances, reducing agents or organic materials.  Use water in large amounts. 
EXPLOSION Risk of fire and explosion.    In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation Cough. Sore throat. Blue lips, fingernails and skin. Abdominal cramps. Confusion. Convulsions. Dizziness. Headache. Nausea. Unconciousness.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness.  Protective gloves.  First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer for medical attention . 
Eyes Redness. Pain.  Wear safety goggles or eye protection in combination with breathing protection.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal pain. Diarrhoea. Shortness of breath. Vomiting. Further see Inhalation.  Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT absorb in saw-dust or other combustible absorbents.

Transport Emergency Card: TEC (R)-51S1495.
NFPA Code: H1; F0; R2; OX. 
Separated from combustible substances, reducing agents and incompatible materials. See Chemical Dangers. 

IMPORTANT DATA
Physical State; Appearance
ODOURLESS COLOURLESS CRYSTALS OR WHITE GRANULES. 

Physical dangers
No data. 

Chemical dangers
Decomposes above 300°C . This produces oxygen, which increases fire hazard and toxic fumes (chlorine). This increases fire hazard. The substance is a strong oxidant. It reacts with combustible and reducing materials. This generates fire and explosion hazard. Reacts with many organic materials. This produces shock-sensitive mixtures. This generates explosion hazard. Attacks zinc and steel. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. 

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

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the blood. This may result in formation of methaemoglobin. The substance may cause effects on the kidneys. This may result in kidney impairment. The effects may be delayed. See Notes. Medical observation is indicated. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at ~300°C
Melting point: 248°C
Density: 2.5 g/cm³
Solubility in water, g/100ml at 20°C: 100  
 

NOTES
The substance is entirely decomposed at temperature higher than 300°C.
Will turn shock-sensitive if contaminated with organic materials.
Marketed formulations contain a flame retardant.
Depending on the degree of exposure, periodic medical examination is suggested.
Rinse contaminated clothes (fire hazard) with plenty of water.
Dervan, Defol, Chlorax and Atlacide are trade names.
Card has been partly updated in October 2004.
