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.

BARIUM CHLORIDE, DIHYDRATE ICSC: 0615
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/m as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004).
MAK: (as Ba) (Inhalable fraction) 0.5 mg/m; 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 20C 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
Melting point: 113C (see Notes)
Density: 3.86 g/cm
Solubility in water, g/100 ml at 26C: 37.5 (good))
ENVIRONMENTAL DATA
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. See also ICSC0614 Barium chloride. Card has been partly updated in October 2005. See sections Occupational Exposure Limits, Emergency Response.
