This section is devoted to assist those who are designing tanks or tank installations for the storage of flammable or volatile liquids, and to aid in the specification and use of tank fittings and related equipment designed to provide optimum efficiency and maximum protection for the tank and its contents. The topics covered include:

  1. The need for providing pressure and vacuum relief for storage tanks.
  2. Methods of protecting flammable vapors in the tank, and in connecting piping, against a source of ignition.
