Pump Safety NoticeIt is unsafe to operate a centrifugal pump when both the suction and dischargeports are closed off by valves at the same time. Such circumstances can result inthe disintegration of the pump housing.This phenomenon is fully appreciated in the engineering profession and stated inthe pump literature. When a pump operates with closed valves, nearly all themotor power output is converted to heat and the temperature of the trapped liquidwill continue to rise.As it does, the liquid will expand and additional pressure will be created as theliquid expands eventually to above the liquid boiling point. The temperature willeventually stabilize where heat losses from the pump housing equal the heatgenerated. However at this point the internal pressure may exceed that for whichthe pump was designed.8
Waste and Hazardous MaterialsStorage and Disposal of WasteAll waste materials must be stored in sealed nalgen waste containers. Thecontainers must be clearly labeled WASTE with the contents of each chemicalcomponent in mol % or volume % concentration written clearly on the container.The container must also be labeled with the group / experiment name and thedate. The labeled and sealed container must be placed in the waste collectionarea located in the south-east corner of senior lab. Any chemicals or materialsthat require temporary storage until the next lab period must also be labeled withthe contents of each chemical component in mol % or volume % concentrationwritten clearly on the container, do not label temporary storage container aswaste. If the material to be temporarily stored is flammable it MUST be stored inthe flammables cabinets located on the east wall of senior lab. If the chemicalsare not flammable and not hazardous they may be stored in sealed containersnext to the ulfiltration equipment, the containers must be properly labeled aspreviously described. Check with the lab manager before deciding on theprocedure for temporary storage of chemicals.9
