Molecular Formula Be (OH) ₂
molecular 43.04 white or yellow powder; vapor pressure; the temperature of 138 ° C (decomposition); solubility : dissolved in acid, alkali; density : relative density (water = 1) 1.91; Stability : stability; risk Marker 14 (Judaipin); the main purposes : to nuclear technology and manufacturing, such as beryllium oxide from

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested.
health hazards : Short-term exposure can cause acute beryllium disease, mainly for acute chemical bronchitis or pneumonia. Often liver swelling, tenderness and even jaundice. Long-term exposure to a small amount of beryllium to be chronic beryllium disease occurred. In addition to weakness, weight loss, loss of appetite, often lightheadedness, chest pain, shortness of breath and coughing. Lung X-ray inspection in three types : type particles, reticulated and nodular type. Advanced can happen right heart failure. Skin lesions are dermatitis, skin ulcers and granuloma.

two, toxicology information and environmental behavior

acute toxicity : LD₅₀3.8mg/kg (RATS)
hazardous characteristics : Unburning. Heat released by the decomposition of toxic gases.
combustion (decomposition) product : the possible harmful toxic fumes.

3. Emergency Monitoring Methods :

4. Laboratory monitoring methods :
AAS; Plasma Spectrometry

5. Environmental standards :
China (TJ36-79) Workshop harmful substances in the air that the maximum allowable concentration 0.001mg/m3
former Soviet air workshop harmful substances maximum allowable concentration ansformation / m3 [Be]

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 : Workers should wear headgear electric powered air-purifying respirators and dust. When necessary, isolated wear respirators.
eye protection : Respiratory Protection has been protective.
physical protection : Cruise-wear protective clothing 52,400.
hand protection : Wear 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. Implementation of pre-employment and periodic medical examinations.

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 to seek medical treatment.

fire fighting methods : firefighters must wear a gas mask filter type (full cover), or isolated respirators, wearing fire protective body suits, upwind of the fire. Extinguishant : sand, water.
