I-1 Pump Safety Tips
Maintenance personnel should be aware of potential hazards to reduce the risk of accidents
Safety Apparel
Insulated work gloves when handling hot bearings or using bearing heater.
Heavy work gloves when handling parts with sharp edges, especially impellers
Safety glasses (with side shields) for eye protection, especially in machine shop areas.
Steel-toed shoes for foot protection when handling pants, heavy tools, etc.
Other personal protective equipment to protect against hazardous/toxic fluids.
Couplings Guards:
Never operate pump without a coupling guard properly installed.
Flanged Connections:
Never force piping to make a connection with a pump.
Use only fasteners of the proper size and material.
Ensure there are no missing fasteners.
Beware of corroded or loose fasteners.
Operation:
Do not operate below minimum rated flow, or with suction/discharge valves closed.
Do not open vent or drain valves, or remove plugs while system is pressurized.
Maintenance Safety:
Always lockout power.
Ensure pump is isolated from system and pressure is relieved before disassembling pump, removing plugs, or disconnecting piping.
Use proper lifting and supporting equipment to prevent serious injury.
Observe proper decontamination procedures.
Know and follow company safety regulations.
Never apply heat to remove impeller.
Observe all cautions and warnings highlighted in pump instruction manual.
