	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Not combustible but enhances combustion of other substances. 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 flammables. 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 .

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: face shield and particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered dry containers. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT absorb in saw-dust or other combustible absorbents.	According to UN GHS Criteria May intensify fire; oxidizer Harmful if swallowed Causes skin irritation Causes serious eye damage May cause respiratory irritation Toxic to aquatic life with long lasting effects Transportation UN Classification UN Hazard Class: 5.1; UN Pack Group: II
STORAGE
Store only in original container. Separated from flammable substances and incompatible materials. See Chemical Dangers. Well closed. Fireproof. Dry. Provision to contain effluent from fire extinguishing. Store in an area without drain or sewer access.
PACKAGING
Airtight.

SODIUM DICHLOROISOCYANURATE

ICSC: 0437

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance WHITE CRYSTALLINE 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). The substance is a strong oxidant. It reacts violently with combustible and reducing materials. Reacts violently with hypochlorites, alkaline compounds, acids and water. This generates fire and explosion hazard.	Formula: C₃Cl₂N₃O₃.Na Molecular mass: 220.96 Decomposes at 230°C Density (at 20°C): 0.96 g/cm³ Solubility in water, g/100ml: 25 (freely soluble)
