	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Not combustible but enhances combustion of other substances. Many reactions may cause fire or explosion. See Chemical Dangers. Risk of fire and explosion.	NO contact with flammables. NO contact with organic materials, powdered metals, ammonium salts or reducing agents. Do NOT expose to friction or shock. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust.	In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.

PREVENT DISPERSION OF DUST! STRICT HYGIENE!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Sore throat. See Ingestion.	Use ventilation (not if powder), local exhaust or breathing protection.	Fresh air, rest. Artificial respiration may be needed. 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. Blue lips, fingernails and skin. Confusion. Convulsions. Diarrhoea. Dizziness. Headache. Nausea. Unconsciousness. Vomiting. Weakness.	Do not eat, drink, or smoke during work.	Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Rest. Refer for medical attention .

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Consult an expert! Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water. Do NOT absorb in saw-dust or other combustible absorbents.	According to UN GHS Criteria Transportation UN Classification UN Hazard Class: 5.1; UN Subsidiary Risks: 6.1; UN Pack Group: II
STORAGE
Separated from combustible substances, reducing agents, ammonium compounds, metal powders and food and feedstuffs.
PACKAGING
Do not transport with food and feedstuffs.

ICSC: 0613

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS CRYSTALLINE POWDER. Physical dangers Chemical dangers Mixtures with organic compounds, reducing agents, ammonia-containing agents and metal powders are shock-sensitive. Decomposes violently on heating. This produces oxygen and toxic fumes. This generates fire and explosion hazard. The substance is a strong oxidant. It reacts with combustible and reducing materials.	Formula: BaCl₂O₆ / Ba(ClO₃)₂ Molecular mass: 304.2 Decomposes at 250°C Density: 3.2 g/cm³ Solubility in water, g/100ml: 27.4 (good)

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation 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 and nervous system. This may result in the formation of methaemoglobin. Exposure could cause hypokalaemia. This may result in cardiac disorders and muscular disorders. The effects may be delayed. Medical observation is indicated. Exposure could cause death.	Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly 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 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 and nervous system. This may result in the formation of methaemoglobin. Exposure could cause hypokalaemia. This may result in cardiac disorders and muscular disorders. The effects may be delayed. Medical observation is indicated. Exposure could cause death.

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

Effects of long-term or repeated exposure

OCCUPATIONAL EXPOSURE LIMITS
TLV: 0.5 mg/m³, as TWA; A4 (not classifiable as a human carcinogen). MAK: (as Ba): 0.5 mg/m³; peak limitation category: II(8); pregnancy risk group: D. EU-OEL: (as Ba): 0.5 mg/m³ as TWA

ENVIRONMENT
The substance is harmful to aquatic organisms.

NOTES
Depending on the degree of exposure, periodic medical examination is suggested. The symptoms of paralysis do not become manifest until some hours have passed. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Rinse contaminated clothing with plenty of water because of fire hazard.
