	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Gives off irritating or toxic fumes (or gases) in a fire. Risk of fire and explosion on contact with reducing agents, water or many substances. See Chemical Dangers.	NO contact with incompatible substances.	Use water in large amounts. NO carbon dioxide, powder. In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water.

PREVENT DISPERSION OF DUST!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Sore throat.	Use local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	Redness. Pain.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention if skin irritation occurs. See Notes.
Eyes	Redness. Pain. Severe burns.	Wear safety goggles or eye protection in combination with breathing protection if powder.	Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention.
Ingestion	Sore throat. Burning sensation.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention .

SODIUM DICHLOROISOCYANURATE DIHYDRATE

ICSC: 1785

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance WHITE POWDER WITH PUNGENT ODOUR. Physical dangers Chemical dangers Decomposes on heating and on contact with water. This produces toxic gases including chlorine (see ICSC 0126). Reacts violently with hypochlorites, alkaline compounds, acids and water. This generates fire and explosion hazard.	Formula: C3H4Cl2N3NaO5 Molecular mass: 256 Decomposes at > 240°C Density (at 20°C): 0.96 g/cm³ Solubility in water, g/100ml at 25°C: 25 (freely soluble)
