Safety & Transport Information

Water and stomach acids solubilize barium salts and can cause poisoning. Symptoms are vomiting, colic, diarrhea, slow irregular pulse, transient hypertension, and convulsive tremors and muscular paralysis. Death may occur in a few hours to a few days. Half-life of barium in bone has been estimated at 50 days. Dust is dangerous and explosive when exposed to heat, flame, or chemical reaction. Violent or explosive reaction with water, CCl4, fluorotrichloromethane, trichloroethylene, and C2Cl4. Incompatible with acids, C2Cl3F3, C2H2FCl3, C2HCl3 and water, 1,1,2-trichlorotrifluoroethane, and fluorotrichloroethane. The powder may ignite or explode in air or other oxidizing gases. See also BARIUM COMPOUNDS (soluble).Analytical Methods: For occupational chemical analysis use NIOSH: Barium, Soluble Compounds, 7056.
Risk Codes:
R11 - Highly flammable
R14/15 - Reacts violently with water, liberating extremely flammable gases
R25 - Toxic if swallowed
R26 - Very toxic by inhalation
R34 - Causes burns
R36/37/38 - Irritating to eyes, respiratory system and skin
Safety Codes:
S16 - Keep away from sources of ignition - No smoking
S23 - Do not breathe gas/fumes/vapour/spray (appropriate wording to be specified by the manufacturer)
S26 - In case of contact with eyes, rinse immediately with plenty of water and seek medical advice
S36 - Wear suitable protective clothing
S36/37 - Wear suitable protective clothing and gloves
S36/37/39 - Wear suitable protective clothing, gloves and eye/face protection
S43 - In case of fire use ... (indicate in the space the precise type of fire-fighting equipment. If water increases the risk add - Never use water)
S45 - In case of accident or if you feel unwell seek medical advice immediately (show the label where possible)
Hazard Classes:
8
Hazard Symbols:
Flammable (pyrophoric) at room temperature in powder form; store under inert gas, petroleum, or other oxygen-free liquid. When heated to approximately 200C in hydrogen, barium reacts violently, forming BaH2. TLV: for all soluble barium compounds, 0.5 mg/m3 (as barium).

Storage temperature :
water-free area
RID/ADR certification :
UN 3264 8 / PG 3
