High Pressure Hazard
Fluids processed by a pump are under pressure. This creates a hazard to
personnel working in the area should a leak occur. Leaking high pressure
fluid may cause injury by startling personnel or from actual contact with the
leaking fluid.
To minimize the risk of this hazard:
1. All installation, maintenance, and service of piping, valves and other
controls must be performed by trained and authorized plumbers only. This
applies to process piping and cleaning/sanitizing piping.
2. All plumbing installation must comply with all applicable codes and
standards including those established by OSHA.
3. Never disconnect any lines or fittings (whether process or cleaning/
sanitizing) or disassemble the pump when lines are under pressure.
4. Should a leak occur, immediately find the cause and stop the leak.
Never operate the pump with both the inlet valve and the outlet valve in
closed positions. If the pump runs with liquid in it, while the valves controlling
the suction and discharge lines are both closed, the liquid in the pump will
heat up and turn into vapor, causing a risk of explosion.
To eliminate the risk of explosion, it is strongly recommended that the
following be included in the system:
1. A pressure relief device which relieves pressure and contains any
discharge, or
2. A thermal/pressure overload device to isolate the pump motor in the
event of excessive temperature/pressure.
Leaking Fluid Hazard
Fluid leaks or spills may occur in any pumping system. This creates a hazard
to personnel due to slippery floor conditions or contact with possibly
hazardous fluids.
To minimize the risk of this hazard:
1. Always clean up leaks and spills immediately.
2. Find and correct the cause of the leak immediately.
