Secondary containment cap apparatus for either permanent or removable attachment to a primary chlorine container turret

A primary container apparatus for containing a hazardous fluid, comprising:

• a primary container having a primary container wall with a primary container turret opening having a turret opening perimeter wall and a perimeter wall rim, said primary container containing chlorine gas at a certain chlorine gas pressure;
• at least four fluid passing container valves;
• a pressure containment cap comprising a cap wall shaped to define a concave cap interior and a cap abutment port, said cap abutment port having a cap abutment port rim and a valve mounting plate extending over and covering said turret opening in sealing relation with said perimeter wall, said valve mounting plate having at least four valve ports each fitted with one of said fluid passing container valves, said valve mounting plate further comprising a first valve mounting plate attachment means securing said valve mounting plate to said turret opening perimeter wall with at least sufficient connection strength to retain said valve mounting plate in sealing relation with said turret opening perimeter wall against the certain chlorine gas pressure, and a second valve mounting plate attachment means fastening said valve mounting plate to said cap abutment port rim with at least the connection strength of said first valve mounting plate attachment means to retain said container cap in sealing relation with said valve mounting plate against the certain chlorine gas pressure;
• wherein said container cap covers and encloses said fluid passing container valves to provide secondary containment of said fluid passing container valves.

A primary container apparatus for containing a gaseous hazardous fluid, comprising:

• a primary container having a primary container wall with a primary container turret opening having a turret opening perimeter wall and a perimeter wall rim, said primary container containing a gaseous hazardous fluid at a certain gas pressure;
• at least two fluid passing container valves;
• a pressure containment cap comprising a cap wall shaped to define a concave cap interior and a cap abutment port, said cap abutment port having a cap abutment port rim and a valve mounting plate extending over and covering said turret opening in sealing relation with said perimeter wall, said valve mounting plate having at least two valve ports each fitted with one of said fluid passing container valves, said valve mounting plate further comprising a first valve mounting plate attachment means securing said valve mounting plate to said turret opening perimeter wall with at least sufficient connection strength to retain said valve mounting plate in sealing relation with said turret opening perimeter wall against the certain gas pressure, and a second valve mounting plate attachment means fastening said valve mounting plate to said cap abutment port rim with at least the connection strength of said first valve mounting plate attachment means to retain said container cap in sealing relation with said valve mounting plate against the certain gas pressure;
• wherein said container cap covers and encloses said fluid passing container valves to provide secondary containment of said fluid passing container valves.

A primary container apparatus for containing a gaseous hazardous fluid, comprising:

• a primary container having a primary container wall with a primary container turret opening having a turret opening perimeter wall and a perimeter wall rim, said primary container containing at least two eduction pipes extending substantially to the primary container turret opening and containing a gaseous hazardous fluid at a certain gas pressure;
• at least two fluid passing container valves;
• a pressure containment cap comprising a cap wall shaped to define a concave cap interior and a cap abutment port, said cap abutment port having a cap abutment port rim and a valve mounting plate extending over and covering said turret opening in sealing relation with said perimeter wall, said valve mounting plate having at least two valve ports each fitted with one of said fluid passing container valves, said valve mounting plate further comprising a first valve mounting plate attachment means fastening said valve mounting plate to said turret opening perimeter wall with at least sufficient connection strength to retain said valve mounting plate in sealing relation with said turret opening perimeter wall against the certain gas pressure, and a second valve mounting plate attachment means fastening said valve mounting plate to said cap abutment port rim with at least the connection strength of said first valve mounting plate attachment means to retain said container cap in sealing relation with said valve mounting plate against the certain gas pressure;
• wherein said container cap covers and encloses said fluid passing container valves to provide secondary containment of said fluid passing container valves.
