BOTTLES (Holding chemicals and solvents)

All bottles should be adequately labelled with their contents and with the date of preparation or the date of first opening of the bottle.

  • When filling empty bottles always allow 10% dead space for expansion and safe pouring of the contents.
  • Bottles should only be carried in specially designed holders and when pouring the contents from the bottle, support the bottle with both hands.
  • Air sensitive liquids are best stored in sealed brown glass bottles in a cool dark location.
  • When bottles are opened many compounds release toxic gases under pressure, e.g. those containing hydrogen chloride, bromine and ammonia. A face mask, together with appropriate protective clothing, should be worn and the bottle carefully opened beneath a fume hood.

Many suppliers now offer plastic encapsulated winchester bottles for corrosive chemicals which retain the contents should a breakage occur. NEVER hold or carry a bottle by its neck.
