FLAMMABLE, HOT, COLD OR CORROSIVE
FLUID PUMPING
Never operate a pump which is pumping hot, cold,
or corrosive fluids when any part of the pump,
suction system or discharge system is leaking.
Stop the pump immediately if any leakage is
observed. Keep all flame, sparks, or hot objects
away from any part of the pump, suction system, or
discharge system. Shield the pump, suction system
and discharge system to prevent any flammable,
hot, cold or corrosive fluid leakage from dripping or
spraying on any components, flame, sparks, hot
objects or people. Inspect the gaskets and seals for
fluid leakage frequently and replace all worn or
leaking parts.
Selection of the proper gaskets and seals is even
more critical when, hot, cold or corrosive fluids are
being pumped than when other, inherently less
dangerous fluids are used. Contact a Gardner
Denver service representative for assistance in
selecting the proper gaskets and seals before
beginning operation.
Before beginning pumping operations or starting the
pump power source (whether an engine or electric
motor) check the atmosphere all around the
pumping site for the presence of flammable or
explosive vapors. Do not begin operation and stop
ongoing operation if flammable or explosive vapors
are detected. Hot surfaces, sparks, electric current
or engine exhaust could ignite flammable or
explosive vapors. Each engine used as a power
source on pumping units where flammable or
explosive vapors could form should be equipped
with an air inlet shut-off. If flammable or explosive
vapors are present in the pumping site atmosphere,
an engine could continue to run on these vapors
even after the engine fuel line is shut-off if an air
inlet shut-off is not used.
In addition, on pumping units used where flammable
or explosive vapors could form, all electric motors
used as power sources must be of explosion proof
construction and all electrical components and
wiring must meet the current National Electrical
Code for explosive atmospheres.
These precautions must be taken to avoid possible
personal injury, death and/or equipment damage
from explosion, fire or burns.
HIGH PRESSURE LIQUID JETTING, BLASTING
AND CLEANING
Pressure or flow directing devices often receive
pressurized flow through flexible hoses, which can
burst if they are kinked, cut, abraded or are
otherwise worn, damaged or pressured above their
rated capacity. Protect the hose and connections
from damage by people, objects and vehicles. A
broken, cut or otherwise burst hose can release
pressurized fluid which may cause personal injury,
death and/or equipment damage.
High pressure fluid from hand held or hand directed
pressure and flow directing devices may overpower
an operator’s ability to control or direct the device,
which could lead to personal injury, death and/or
equipment damage. The operator must brace
against the backward thrust of a hand held device.
In addition, a safety harness or safety net must be
used when working in an area where the operator
could be injured in a fall. Stand to the side of any
tubing or container being sprayed to avoid back
spray and never operate a hand held device above
shoulder level.
Never direct the pressurized fluid stream at yourself
or any other person, control valves, the pump, pump
drive, suction or discharge systems. The
pressurized stream can cause serious personal
injury or death and can also change valve or control
settings which could dangerously increase the
delivery pressure to the pressure and flow directing
device.
DANGER
Extreme caution must be exercised by
trained and experienced operators when
flammable, hot, cold or corrosive fluids
are being pumped in order to avoid
personal injury, death and/or equipment
damage due to explosion, fire, burn,
extreme cold or chemical attack.
DANGER
Extreme caution must be exercised if any
type of wand, gun, nozzle or any other
pressure and flow directing device is
attached to the pump discharge system
for use in jetting, blasting, cleaning, etc.
This type of equipment must be used with
utmost care by trained, experienced
operators. High pressure fluid streams
can either by direct contact or by
propelling loose objects, cause serious
personal injury or death to the operators
and/or other persons.
