2. The impact on the environment :
a health hazard

pathways : inhaled, ingested.
health hazards : oral manifestations of acute poisoning as nausea, vomiting, abdominal pain, diarrhea, pulse relief, muscular weakness, cardiac rhythm disorders, such as potassium decreased significantly. May arrhythmias and respiratory muscle paralysis and death. Inhalation of dust can cause poisoning, but the clear symptoms of digestive tract. Contact with the high-temperature solution goods may cause skin burns while absorbing poisoning.
chronic effects : long-term exposure to barium compounds workers may have weakness, shortness of breath, salivation, erosive oral mucosal edema, rhinitis, conjunctivitis, diarrhea, tachycardia, high blood pressure, and alopecia.

6. Emergency treatment and disposal methods :
a leakage contingency

isolation leak contaminated areas, restricting access. Recommended emergency personnel wearing self-contained breathing apparatus to wear protective clothing. Do not direct contact with leakage. A small leak : Dust to avoid using cleaner shovel collection in a dry, clean, covered containers. Large Leak : plastic sheeting, canvas cover and reduce dispersion. Then the collection, recycling or shipped to the disposal of waste disposal sites.

two protective measures

respiratory protection : its possible exposure to dust, must wear headgear electric powered air-purifying respirators and dust. Emergency rescue or evacuation, it is recommended to wear air respirators.
eye protection : Respiratory Protection has been protective.
physical protection : Acid and Basic Resistance to wear rubber clothing.
hand protection : Acid and Basic Resistance wearing rubber gloves.
other : work site prohibit smoking, eating and drinking. Work to complete, take a shower. Separate storage of toxic pollution by the clothes, washed standby. To maintain good health habits.

three, and emergency measures

contact with the skin : stripped of contaminated clothing, use soap and water thoroughly washed skin.
eye contact : Did eyelid, mobile or saline irrigation water. Medical treatment.
Inhalation : rapidly from the scene to fresh air. To keep the airway patency. If breathing is difficult, give oxygen. If breathing stop immediately mouth. Medical treatment. Fresh into
: warm water to drink enough, the symptoms, and with 2% to 5% sodium hydrosulfite gastric lavage, catharsis. Medical treatment.

fire fighting methods : This Unburning. Extinguishing agents : water, sand.
