TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.		In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION

EXPOSURE		PREVENT DISPERSION OF DUST! STRICT HYGIENE!
Inhalation	Cough. Sore throat. See Ingestion.	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.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes	Redness.	Safety spectacles or eye protection in combination with breathing protection.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion	Abdominal pain. Nausea. Diarrhoea. Vomiting. Weakness. Dullness. Unconsciousness.	Do not eat, drink, or smoke during work.	Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Rest.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment. Personal protection: P2 filter respirator for harmful particles.	Xn Symbol R: 20/22 S: (2-)28 Note: A UN Hazard Class: 6.1 UN Pack Group: III	Do not transport with food and feedstuffs.

EMERGENCY RESPONSE	SAFE STORAGE
Transport Emergency Card: TEC (R)-61S1564-III or 61GT5-III	Separated from food and feedstuffs.

IMPORTANT DATA

Physical State; Appearance
WHITE SOLID IN VARIOUS FORMS

Chemical dangers
The substance decomposes on heating producing toxic fumes.

Occupational exposure limits
TLV: (as Ba) 0.5 mg/m³ as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004).
MAK: (as Ba) (Inhalable fraction) 0.5 mg/m³; Peak limitation category: II(2); (DFG 2004).

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

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 short-term exposure
The substance is irritating to the eyes, the skin and the respiratory tract. The substance may cause effects on the nervous system. Exposure could cause hypokalaemia, resulting in cardiac disorders and muscular disorders. Exposure may result in death.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Melting point: 113°C (see Notes) Density: 3.86 g/cm³ Solubility in water, g/100 ml at 26°C: 37.5 (good))	The substance is harmful to aquatic organisms.

NOTES

The apparent melting point caused by loss of crystal water is given.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
