1、The physical and chemical properties

Appearance & Properties: white crystalline powder or colorless microstrip pearl luster of phosphorus or hexagonal triclinic crystal. Soapy, no smell, taste tiny acid then sweet. Heating to 100 ~ 105 ℃ when lose a molecule of water then becomes metaboric acid, under 104 ~ 160 ℃ for a long time turns into pyroboric acid, in higher temperature will turn into anhydride. The PH value of 0.1 mol/L solutionis 5.1. 1 g of this material can soluble in 18 ml cold water, 4 ml boiling water, 18 ml cold ethanol, 6 ml boiling ethanol and 4 ml glycerinum. It’s solubility in water can increase with the hydrochloric acid, citric acid and tartaric acid.

Melting point: 184 ℃

Boiling point: 300 ℃

Density: relative density 1.43 (water = 1)

Molecular Weight: 61.83

Stability: is a stable crystalline, usually chemical reactions will not occur. When temperature, humidity upheaval it will agglomerate.

USES: used as industrial raw materials like glass, paint, enamel, porcelain, pharmaceutical and so on.

2、Environmental Impact

2.1 Health Hazard

Invasive ways: inhalation, ingestion, percutaneous absorption. Health hazard: serious internal will cause death, death minimum: adult oral 640 mg/kg, skin intravenous 8.6 g/kg, intravenous 29 mg/kg; Baby oral 200 mg/kg.

The highest allowable concentration in the air 10 mg/m3. Industrial production, the only known cause skin irritation, conjunctivitis, bronchitis, generally no poisoning occurs. Oral cause acute poisoning, main show is gastrointestinal symptoms, such as nausea, vomiting, abdominal pain, diarrhea, then dehydration, shock, coma or acute renal failure, can have a high fever, liver and kidney damage and convulsion, the person that weigh can be lethal. Widespread bright red skin rash, the person that weigh into exfoliative dermatitis. This product is easily absorbed by skin damage caused by poisoning. Chronic poisoning: small amount only absorbed by the gastrointestinal tract or skin for a long time, can be mild digestive tract symptoms occur, dermatitis, bald, and liver and kidney damage.

2.2 Hazard emergency treatment

Skin Contact: remove contaminated clothing, flush with plenty of liquid water

Eye Contact: mention eyelid, irrigate with flowing water or normal saline.

Inhalation: escape to fresh air. If breathing hard, give oxygen immediately.

Ingestion: drink enough water, vomiting.  Gastric lavage, drainage.

2.3 Environmental hazards

Combustion hazard: this product non-combustible, stimulative.

Dangerous characteristic: decomposite poisonous gases after high thermal.

Hazardous combustion products: boron oxide.

3、Emergency disposal method

3.1 Emergency Processing

Isolate leakage pollution area, restricted movement. Recommend emergency personnel wear dust mask (comprehensive cover), protective clothing. Mixed with sand, dry lime or soda ash. Sweep up carefully and transferred to the safe place. If leaks heavy, covered with plastic cloth, canvas. Collect recycling or shipped to the disposal of waste places.

3.2 OPERATION CAUTIONS

Obfurage operation, strengthen ventilated. Operators must trained speciallu, strictly abide by the operation procedures. Suggest operators wear self-priming filter type dust mask, wearing chemical safety protective glasses gas permeability overalls and rubber gloves. Avoid dust. Avoid contact with the base class and potassium. Move carefully, keep the packing intact to prevent leakage. Equipped with emergency treatment equipment. Destroy may remain inside empty containers.

4、Environmental Standards

USSR MAC (mg/m3) : 10

TLVTN: not formulate standards

TLVWN: not formulate standards

5、Protective Measures

Respiratory protection: When excessive dust concentration in the air, must wear self-priming filter type dust mask.

During emergency rescue or evacuation, air breathing apparatus should be worn.

Eye protection: wear chemical safety goggles.

Body protection: wear protective material penetration overalls.

Hand protection: wear rubber gloves.

Other protective: after work, shower change clothes.  Maintain good health habits.

6、Transport cautions

Packing intact, safe loading. During transportation, ensure that the container does not leak, collapse, fall, and not damaged. Strictly prohibit packing with alkaline, potassium, edible chemical and so on. During transportation, prevent insolation, rain and heat. Clean up the vehicle after transportation.

7、Storage cautions

Stored in a dry clean room, do not open to pile up, avoid rain or moisture. Installed in a covered wagon, or belt in the car cabin transportation, should not mix with moisture content and non-ferrous materials piled up, the means of transport must be dry and clean.
