Liquid mercury also known as Colloidal mercury; Hydrargyrum metallic mercury; Quick silver or Liquid silver and is often contained in sealed glass phials within electrical switch gear.

Mercury is corrosive and harmful if inhaled or absorbed through intact or unbroken skin. It can cause eye and skin irritation and possible burns. Exposure may cause severe respiratory or digestive tract irritation with possible burns and could lead to long term liver, brain and kidney damage.
