Molecular Formula Rb
molecular 85.46

cereus soft silver-white metal; Vapor Pressure 0.13kPa (297 ° C); the temperature of 38.9 ° C; the boiling point of 688 ° C; solubility; density : relative density (water = 1) 1.53; Stability : unstable; risk Marker 10 (case of wet flammable substances); the main purposes : used in the manufacture of solar cells and vacuum tubes for catalyst

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested.
health hazards : Rubidium has yet to prove any of the human toxicity, and no reported cases of poisoning.

two, toxicology information and environmental behavior

acute toxicity : LD₅₀1200mg/kg (internal organs of mice cavity)
hazardous characteristics : high chemical reactivity, exposure to the air or oxygen combustion and self explosion molten spatter. With the air of oxygen-generating reaction oxides, such as a mixture of organic matter, create an explosive reaction. With water or tidal fierce reaction produce hydrogen, heat large, cause a fire or explosion. With halogens, phosphorus, sulfur and dramatic chemical reactions that cause a fire.

3. Emergency Monitoring Methods :

4. Laboratory monitoring methods :
plasma spectrometry; AAS

5. Environmental standards :

6. Emergency treatment and disposal methods :
a leakage contingency

isolation leak contaminated areas, restricting access. Cut off the fire source. Recommended emergency personnel wearing self-contained breathing apparatus, wearing fire protective clothing. Do not direct contact with leakage. A small leak : Income metal containers and stored in kerosene or liquid paraffin. Large Leak : with the technology sector linkages, and to determine methods to remove.

two protective measures

respiratory protection : Most do not need special protection, but suggested that under special circumstances, since wearing suction filtered respirators.
eye protection : Wear protective chemical safety glasses.
physical protection : wear chemical protective clothing.
hand protection : Wear rubber gloves.
other : no smoking scene work. Pay attention to personal hygiene.

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. Medical treatment.

fire fighting methods : not water, halohydrocarbons (1211 extinguishing agents), sodium bicarbonate, potassium bicarbonate as a fire extinguishing agent. That is the use of graphite powder and dry sand is not applicable. To use dry powder of sodium chloride, sodium carbonate powder, calcium carbonate powder fire.
