TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire.
NO contact with flammable substances. NO contact with strong reducing agents, strong bases, ammonia, urea, water.
Powder, alcohol-resistant foam, water in large amounts, carbon dioxide.
EXPLOSION Risk of fire and explosion on contact with strong reducing agents, strong bases, ammonia, urea, water.

In case of fire: cool drums, etc., by spraying with water but avoid contact of the substance with water.
EXPOSURE
PREVENT DISPERSION OF DUST! STRICT HYGIENE!

Inhalation Cough. Sore throat.
Local exhaust or breathing protection.
Fresh air, rest.
Skin Redness. Skin burns. Pain.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
Eyes Redness. Pain. Loss of vision. Severe deep burns.
Face shield or eye protection in combination with breathing protection if powder.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion Burning sensation. Sore throat.
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Rest. Refer for medical attention.

SODIUM DICHLOROISOCYANURATE ICSC: 0437
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALLINE POWDER, WITH PUNGENT ODOUR.

CHEMICAL DANGERS:
The substance decomposes on heating, on contact with water, producing toxic fumes including chlorine. The substance is a strong oxidant and reacts violently with combustible and reducing materials. Reacts violently with many substances, causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of dust and by ingestion.

INHALATION RISK:
Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes, the skin and the respiratory tract. Corrosive on ingestion.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis.
PHYSICAL PROPERTIES
Decomposes below melting point at 230C
Relative density (water = 1): >1
Solubility in water, g/100 ml: 25
ENVIRONMENTAL DATA
This substance may be hazardous in the environment; special attention should be given to water quality.
NOTES
Also consult ICSC 0126 Chlorine. Card has been partly updated in October 2005. See sections EU classification, Emergency Response.
