  The company can also improve quality of the products according to users requirement.
  
  Usage:
  Used in manufacturing fluorine, fluorinated salts, fluoric complex acid, fluo-refrigerant, fluoroalkane extinguishant and fluoric intermedium, and also greatly used as a fluorinating agent and an etchant in pharmaceutical, chemical and electronic industry.
  
  Packing & shipment:
  Usually filled in 40, 340, 680, 820kg cylinders, and also shipped by ISO containers or tanks. Its category of dangerous goods is 8, and its packing category is I.
  
  Security:
  While handling hydrogen fluoride, workers should put on the protecting clothes, gloves and goggles. Hydrogen fluoride can quickly pervade into and harm deeply the skin. Great inhalation or cauterization will result in endangering the body. If this accident happens, first aid ought to be taken immediately.
