Precautions must be taken to prevent physical injury. Pumpage must be han-
dled and disposed of in conformance with applicable environmental regula-
tions.

WARNING

Operator must be aware of pumpage and safety precautions to prevent physi-
cal injury.

WARNING

Lock out driver power to prevent accidental startup and physical injury.

CAUTION

Allow all system and pump components to cool before handling them to pre-
vent physical injury.

WARNING

Never apply heat to remove an impeller. The use of heat may cause an explo-
sion due to trapped fluid, resulting in severe physical injury and property dam-
age.

CAUTION

Wear heavy work gloves when handling impellers as sharp edges may cause
physical injury.

CAUTION

Wear insulated gloves when using a bearing heater. Bearings will get hot and
can cause physical injury.

WARNING

Noise:

Sound pressure levels may exceed 80 dbA in operating process plants. Clear
visual warnings or other indicators should be available to those entering an
area with unsafe noise levels. Personnel should wear appropriate hearing pro-
tection when working on or around any equipment, including pumps. Consider
limiting personnel’s exposure time to noise or, where possible, enclosing
equipment to reduce noise. Local law may provide specific guidance regard-
ing exposure of personnel to noise and when noise exposure reduction is re-
quired.

WARNING

Temperature:

Equipment and piping surfaces may exceed 130ºF (54ºC) in operating proc-
ess plants. Clear visual warnings or other indicators should alert personnel to
surfaces that may reach a potentially unsafe temperature. Do not touch hot
surfaces. Allow pumps operating at a high temperature to cool sufficiently be-
fore performing maintenance. If touching a hot surface cannot be avoided,
personnel should wear appropriate gloves, clothing, and other protective gear
as necessary. Local law may provide specific guidance regarding exposure of
personnel to unsafe temperatures.
