SODIUM CHLORATE	ICSC: 1117 (October 1999)
Chloric acid, sodium salt

CAS #: 7775-09-9

UN #: 1495

EC Number: 231-887-4

	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. Risk of fire and explosion.	NO contact with flammables, combustible substances, reducing agents or organic materials.	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	Cough. Sore throat. Blue lips, fingernails and skin. Abdominal cramps. Confusion. Convulsions. Dizziness. Headache. Nausea. Unconsciousness.	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. Refer for medical attention .
Eyes	Redness. Pain.	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	Abdominal pain. Diarrhoea. Shortness of breath. Vomiting. Further see Inhalation.	Do not eat, drink, or smoke during work.	Rinse mouth. Refer for medical attention .

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting. 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 Transportation UN Classification UN Hazard Class: 5.1; UN Pack Group: II
STORAGE
Separated from combustible substances, reducing agents and incompatible materials. See Chemical Dangers.

SODIUM CHLORATE

ICSC: 1117

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance ODOURLESS COLOURLESS CRYSTALS OR WHITE GRANULES. Physical dangers No data. Chemical dangers Decomposes above 300°C . This produces oxygen, which increases fire hazard and toxic fumes (chlorine). This increases fire hazard. The substance is a strong oxidant. It reacts with combustible and reducing materials. This generates fire and explosion hazard. Reacts with many organic materials. This produces shock-sensitive mixtures. This generates explosion hazard. Attacks zinc and steel.	Formula: NaClO₃ Molecular mass: 106.44 Decomposes at ~300°C Melting point: 248°C Density: 2.5 g/cm³ Solubility in water, g/100ml at 20°C: 100

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. Effects of short-term exposure The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the blood. This may result in the formation of methaemoglobin. The substance may cause effects on the kidneys. This may result in kidney impairment. The effects may be delayed. See Notes. Medical observation is indicated.	Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered. Effects of long-term or repeated exposure

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the blood. This may result in the formation of methaemoglobin. The substance may cause effects on the kidneys. This may result in kidney impairment. The effects may be delayed. See Notes. Medical observation is indicated.

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.

Effects of long-term or repeated exposure

OCCUPATIONAL EXPOSURE LIMITS

ENVIRONMENT

NOTES
The substance is entirely decomposed at temperature higher than 300°C. Will turn shock-sensitive if contaminated with organic materials. 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.
