Adherence to these warnings alone, however, is not sufficient it is anticipated that the end user will alsocomply with industry and corporate safety standards. Identifying and eliminating unsafe installation, operating and maintenancepractices is the responsibility of all individuals involved in the installation, operation, and maintenance of industrial equipment.

    Specific to pumping equipment, two significant risks bear reinforcement above and beyond normal safety precautions.

    ! WARNING1 Operation of any pumping system with a blocked suction and discharge must be avoided in all cases.Operation, even for a brief period under these conditions, can cause superheating of enclosed pumpage

    and result in a violent explosion. All necessary measures must be taken by the end user to ensure this

    condition is avoided.

    ! WARNING2 Pumping equipment Instruction, Operation, and Maintenance manuals clearly identify accepted methods fordisassembling pumping units. These methods must be adhered to. Specifically, applying heat to impellers and/or

    impeller retaining devices to aid in their removal is strictly forbidden. Trapped liquid can rapidly expand and result

    in a violent explosion and injury.
