| Hazard Information | Back Directory | [Chemical Properties]
white crystalline powder | [Uses]
In electroplating processes; in metallurgy. | [General Description]
A white crystalline solid. Toxic by skin absorption through open wounds, by ingestion, and by inhalation of hydrogen cyanide from decomposition. Toxic oxides of nitrogen are produced in fires involving BARIUM CYANIDE. | [Air & Water Reactions]
Soluble in water. Gradually decomposed by water and rapidly decomposed by acids to give off hydrogen cyanide, a flammable poison gas. | [Reactivity Profile]
BARIUM CYANIDE is an inorganic cyanide. Members of this class that contain heavy metals tend to explosive instability, most of them are capable of violent oxidation under certain conditions; fusion of metal cyanides with metal chlorates, perchlorates, nitrates, or nitrites can cause violent explosion [Bretherick 1979 p. 101]. | [Health Hazard]
INHALATION OR INGESTION: Exposure to cyanides can cause headache, vertigo, nausea, and vomiting may occur at low concentrations. High concentration causes difficult breathing, palpitation, paralysis, unconsciousness, respiratory arrest, cyanosis, and death. EYES: Irritation. SKIN: Rash, desquamation and itching. | [Fire Hazard]
Special Hazards of Combustion Products: Toxic cyanides and barium oxides. | [Hazard]
Questionable carcinogen. | [Potential Exposure]
Barium cyanide is used in electroplating
and in metallurgy. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately. If
this chemical has been inhaled, remove from exposure, begin
rescue breathing (using universal precautions, including
resuscitation mask) if breathing has stopped and CPR if heart
action has stopped. Transfer promptly to a medical facility.
When this chemical has been swallowed, get medical attention.
Give large quantities of water and induce vomiting. Do
not make an unconscious person vomit. If cyanide poisoning
is confirmed, use amyl nitrate capsules if symptoms develop.
All area employees should be trained regularly in emergency
measures for cyanide poisoning and in CPR. A cyanide antidote
kit should be kept in the immediate work area and must
be rapidly available. Kit ingredients should be replaced
every 1 2 years to ensure freshness. Persons trained in the
use of this kit; oxygen use, and CPR must be quickly available.

UN1565 Barium cyanide, Hazard Class: 6.1;
Labels: 6.1—Poisonous materials. | [Incompatibilities]
Solution is basic. Incompatible with oxidizers
(chlorates, nitrates, peroxides, permanganates, perchlorates,
chlorine, bromine, fluorine, etc.); contact may
cause fires or explosions. Keep away from alkaline materials,
strong acids, & acid salts (release toxic hydrogen cyanide
gas), strong bases. | [Description]
Barium cyanide is a white crystalline powder.Often used in solution. Molecular weight=139.4; Heatof combustion=260.5 3 105 J/kg; Heat of solution 5(exothermic)=26.19 3 105 J/kg. Hazard Identification(based on NFPA-704 M Rating System): Health 3,Flammability 0, Reactivity 0. Soluble in water;solubility=80 g/100 cc at 14℃. | [Waste Disposal]
Precipitate barium with sulfate.
Then add with stirring to alkaline calcium hypochlorite
solution. Let stand 24 hours, then flush to sewer. | [Physical properties]
White crystalline powder; slowly decomposes in air; highly soluble in water, soluble in alcohol. | [Preparation]
Barium cyanide is prepared by reacting barium hydroxide with hydrocyanic acid:
Ba(OH)2 + 2HCN → Ba(CN)2 +2H2O
The product is crystallized from the solution. | [storage]
Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Barium cyanide must be storedto avoid contact with acids; acid salt (such as potassiumbisulfate, calcium biphosphate and calcium nitrate); carbondioxide and strong oxidizers (such as nitrates, chlorates andchlorine) since violent reactions occur. Store in tightlyclosed containers in a cool, well-ventilated area |
