	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	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. See Chemical Dangers.	NO contact with flammables, combustible substances, reducing agents or organic materials. Do NOT expose to friction or shock.	Use water in large amounts. In case of fire: keep drums, etc., cool by spraying with water.

PREVENT DISPERSION OF DUST!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	See Ingestion.	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.
Eyes	Redness.	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	Sore throat. Cough. Abdominal pain. Nausea. Vomiting. Diarrhoea. Blue lips, fingernails and skin. Shock or collapse.	Do not eat, drink, or smoke during work.	Rinse mouth. Refer immediately for medical attention.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. If appropriate, moisten first to prevent dusting. Sweep spilled substance into covered sealable containers. Do NOT absorb in saw-dust or other combustible absorbents. Carefully collect remainder. Then store and dispose of according to local regulations.	According to UN GHS Criteria May cause fire or explosion; strong oxidizer Harmful if swallowed Causes damage to blood and kidneys Transportation UN Classification UN Hazard Class: 5.1; UN Pack Group: II
STORAGE
Store only in original container. Store in an area without drain or sewer access. Separated from combustible substances, reducing agents and incompatible materials. Dry. Well closed. See Chemical Dangers.

SODIUM CHLORATE

ICSC: 1117

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance HYGROSCOPIC ODOURLESS COLOURLESS-TO-WHITE CRYSTALS. Physical dangers Chemical dangers Attacks zinc and steel. The substance is a strong oxidant. It reacts with combustible and reducing materials and strong acids. This generates fire and explosion hazard. Reacts with many organic materials. This produces shock-sensitive mixtures. This generates explosion hazard. Decomposes above 300°C . This produces oxygen, which increases fire hazard. This produces toxic fumes of chlorine.	Formula: NaClO₃ Molecular mass: 106.44 Decomposes at ± 300°C Melting point: 248°C Density: 2.5 g/cm³ Solubility in water, g/l at 20°C: 1000 (freely soluble) Octanol/water partition coefficient as log Pow: -7.18 (estimated)

OCCUPATIONAL EXPOSURE LIMITS

ENVIRONMENT
It is strongly advised not to let the chemical enter into the environment because it is persistent.

NOTES
Will turn shock-sensitive if contaminated with organic substances. Marketed formulations contain a flame retardant. Depending on the degree of exposure, periodic medical examination is suggested. Rinse contaminated clothing with plenty of water because of fire hazard.
