Introduction: Barium dichloride is a white solid, odorless, hygroscopic chemical substance. Bariumdichloride is used in the manufacture of pigments, in the manufacture of other bariumsalts and in fireworks to give a bright green color. It is one of the most common watersolublesalts of barium. Like other barium salts, it is toxic and imparts a yellow-green colorationto a flame. Barium chloride has wide application in the laboratory.

4. Safety and Handling

4.1 Hazard Codes: T

4.1 Risk Statements: R20;R25

4.1 Safety Statements: S45

4.1 Packing Group: III

4.1 Fire Hazard: Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.

4.2 Other Preventative Measures: If employees' clothing has had any possibility of being contaminated with barium chloride ... or liq containing ... /this/ cmpd, employees should change into uncontaminated clothing before leaving the work premises. ... Clothing contaminated with barium chloride ... should be placed in closed containers for storage until it can be discarded or until provision is made for the removal of contaminant from the clothing. If the clothing is to be laundered or otherwise cleaned to remove the contaminant, the person performing the operation should be informed of contaminant's hazardous properties. ... Non-impervious clothing which becomes contaminated with barium chloride ... should be removed promptly and not reworn until the contaminant is removed from the clothing.
Skin that becomes contaminated with barium chloride ... should be promptly washed or showered to remove any contaminant.
Eating and smoking should not be permitted in areas where solid barium chloride ... or liq containing ... /this/ cmpd are handled, processed, or stored. Employees who handle barium chloride ... or liq containing ... /this/ cmpd should wash their hands thoroughly before eating, smoking, or using toilet facilities.
SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. All contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
The worker should immediately wash the skin when it becomes contaminated.
Work clothing that becomes wet or significantly contaminated should be removed or replaced.
Workers whose clothing may have become contaminated should change into uncontaminated clothing before leaving the work premises.
If material not on fire and not involved in fire: Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Do not use water.
Personnel protection: Avoid breathing vapors. Keep upwind. ... Avoid bodily contact with the material. ... Do not handle broken packages unless wearing appropriate personal protective equipment.

4.3 Hazard Class: 6.1

4.3 DisposalMethods: SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

4.4 RIDADR: UN 1564

4.4 Fire Fighting Procedures: If material on fire or involved in fire: Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use foam, dry chemical, or carbon dioxide. Keep run-off water out of sewers and water sources.

Swallowed or inhaled can cause poisoning, it is mainly through the respiratory tract and digestive tract to invade the human body, it will cause drooling and burning esophagus, stomach pain, cramps, nausea, vomiting, diarrhea, high blood pressure, no law firm pulse, cramps, a lot of cold sweat, weak muscle strength, gait, vision and speech problems, difficulty breathing, dizziness, tinnitus, consciousness usually clear. In severe cases, it can cause sudden death. Barium ions can cause muscle stimulant, then gradually transforms into paralysis. Rat oral LD50150mg/kg, mouse peritoneal LD5054mg/kg, rats are intravenously LD5020mg/kg, orally in dog LD5090mg/kg.

6.6 First-aid measure: When skin contacts it, rinsing with water, then thoroughly washing with soap. When eye contacts, flushing with water. So that patients inhaled dust should leave from the contaminated area, move to fresh air place, rest and keep warm, if necessary, artificial respiration should be taken, seek medical attention. When swallowed, immediately rinse the mouth, gastric lavage should be taken with warm water or 5% sodium hydrosulfite for catharsis. Even swallows more than 6h, gastric lavage is also necessary. Intravenous infusion is slowly taken with 1% sodium sulfate of 500ml~1 000ml, intravenous injection can also be taken with 10% sodium thiosulfate of 10ml~20ml. Potassium and symptomatic treatment should be carried out.
Soluble barium salts of barium chloride is rapidly absorbed, so the symptoms develop rapidly, at any time cardiac arrest or respiratory muscle paralysis can cause death. Therefore, first aid must be against the clock.

8. Question & Answer

Barium chloride forms a hydrate which contains 85.25% barium chloride and 14.75% of water of crystallization. what is the formula of this hydrate? How is it determined? Apr 16 2022
This type of question can be solved using simple algebra and some basic chemistry. First, let’s define some variables;- n = The number of molecules of water in the hydrate. p = The percentage of water of crystallisation in the hydrate. w = The molar mass of water. a = The molar mass of anhydrous B...
What is the balanced molecular equation, showing the insoluble precipitate, the total ionic equation, and the net ionic equations of barium chloride + sodium sulfate? Apr 06 2022
OK, here it is. Note that the chemical formula for barium chloride is BaCl2, barium sulfate is BaSO4, sodium sulfate is NaSO4, and sodium chloride is NaCl. BaCl2(aq) + Na2SO4(aq) → BaSO4(s) + 2 NaCl(aq) Now, if you wanted to write this more explicitly then you have to ‘expand’ on what the (aq) m...
Is the reaction between Barium Chloride and Copper Sulfate exothermic or endothermic? Mar 31 2022
Overall reaction BaCl2(aq) + CuSO4(aq) → BaSO4(s) + CuCl2(aq) The net ionic equation Ba2+(aq) + SO4 2−(aq) → BaSO4(s) Enthalpies (heats) of formation, ΔHf0(kJ/mol) Ba2+(aq) = −538.36 SO4 2−(aq) = −907.51 BaSO4(s) = −1465 ΔHrxn = ΔHprod −ΔHreact ΔHrxn = −1465 − [−538.36 + (−907.51)] ΔHrxn = ...
What is the mass of 6.94 mol of barium chloride? Mar 27 2022
The molar mass of barium chloride is found by looking at the formula BaCl2 1 x 137.2 g/mol + 2 x 35.5 g/mol = 208.3 g/mol 6.94 mol x (208.3 g/mol) = 1,445.602 rounded to 3 places gives 1.45 x 10^3 g
