Safety tips
•
Do not allow the waterjet stream to touch any part
of your body—it will cause serious injury. Do not
point the waterjet at anyone.
•
During equipment maintenance, take the system out
of service. The controls must be properly locked and
marked with a warning sign.
•
All personnel required to perform any system oper
-
ating or service function must pay particular atten
-
tion to all warning signs and notices posted in the
plant and on the equipment.
•
All protective guards, shields, and covers must be in
place on the equipment at all times.
•
First aid facilities shall be provided in convenient lo
-
cations throughout the plant. These locations must
be known by all personnel.
•
Always keep the work area around the equipment
clean and free of debris. Oil spillage results in slip
-
pery floors and must be cleaned up immediately.
•
Any unfavorable conditions that may result in inju-
ries shall be reported to the plant supervisor
immediately.
• As a general practice, it is recommended that safety
shoes, glasses, and hearing protection be worn by all
personnel working around the equipment. Do not
wear rings, watches, or necklaces when working
around any equipment that has moving parts.
Mechanical system
•
Don’t start the system unless you know how to stop
it.
•
Never maintain, service, or clean around the equip
-
ment while it is operating.
•
Do not use incorrect tools—it can cause injury or
costly damage to equipment.
•
Never climb on or around the equipment on make
-
shift devices. Use only approved catwalks, ladders,
or platforms.
•
Do not exceed specified pressure setting limits for
pneumatic or hydraulic components. Exceeding
these limits may result in serious injury to personnel
or damage to the equipment.
•
Shield and bundle equipment hoses and cables so
they do not obstruct the operator’s freedom of
movement.
•
Always be alert when working around the
equipment.
•
Clear all tools, parts, and rags from moving parts af
-
ter servicing the equipment.
Electrical system
•
Only a certified electrician shall perform electrical
and/or electronic troubleshooting and servicing of
electrical devices.
•
Always assume that power is ON in all electrical sys
-
tems. Always check and lock out the main power
switches before servicing the equipment. Post a sign,
“Maintenance in Progress—Do Not Energize.”
•
Be aware that live electrical circuits are present in
the control console whenever the master disconnect
is on, regardless of whether the E-Stop is engaged.
•
Disconnect circuit breakers and lock them in the
OFF position before servicing the electrical system. If
this isn’t possible, have someone stand by to prevent
someone from powering up the system.
•
Take extra precautions when servicing the power sys-
tem in a damp environment.
•
Never alter or bypass protective interlocks or devices
unless specifically instructed to do so, and only if all
precautions are followed.
•
You must give capacitors sufficient time for dis-
charge. If this is not possible, discharging should be
done manually and with care.
•
Do not use jumper wires across fuses, fuse holders,
or breakers.
•
Make sure all tools are properly insulated for the job.
Use only proper test apparatus; check regularly to
make sure it is working correctly. Use caution when
connecting a test probe to test points.
•
All replacement wires shall conform to the manufac
-
turer’s specifications, including color coding, wire
numbers, and size.
•
Close the control panel doors or junction box covers
after servicing.
Waterjet system
•
High-pressure water can remain in the system for an
extended time after shutting down the water source.
Always bleed-down system pressure before servicing
any part of the system.
•
Do not touch weep holes with your bare hands or
try to stop water by plugging the holes.
•
Remember that the waterjet stream is a knife. Do
not introduce anything into its path that you do not
intend to cut.
