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      
 
EXPOSURE   PREVENT DISPERSION OF DUST!  
Inhalation Cough. Sore throat. Wheezing. Shortness of breath. Local exhaust or breathing protection. Fresh air, rest. Half-upright position. Refer for medical attention.
Skin Redness. Burning sensation. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes Redness. Pain. 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 take to a doctor.
Ingestion Burning sensation. Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Do NOT induce vomiting.

SPILLAGE DISPOSAL PACKAGING & LABELLING

IMPORTANT DATA
Physical State; Appearance
WHITE CRYSTALS

Chemical dangers
Reacts with water to produce chlorendic acid.

Occupational exposure limits
TLV not established.

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

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
The substance is irritating to the eyes, the skin and the respiratory tract.

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation exposure may cause asthma.


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: 231-235°C
Density: 1.73 g/cm³
Solubility in water: reaction
 

NOTES
The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Anyone who has shown symptoms of asthma due to this substance should avoid all further contact with this substance.
