When operating a pressure and flow directing
device, use only equipment which automatically
shuts off flow when an operator releases hand or
foot pressure on the pressurized flow trigger control
to prevent injury if the operator is overpowered or
becomes disabled.
Check to insure this automatic shut-off equipment is
operating properly before every use and
never
circumvent the automatic shut-off for any reason or
by any means when operating the equipment.
When operating any type of high pressure liquid
jetting, blasting or cleaning devices the operators
must always wear protective clothing including, but
not limited to, a hard hat with full face visor, heavy
duty rain coat and pants, boots with nonskid sole
and safety toe, rubber gloves with rough grip
surface and ear noise protection.
Full operator attention and alertness are required
when operating this equipment to avoid personal
injury, death and/or equipment damage. The
operators should take frequent rest breaks and
cease operations when they become tired or
distracted.
Before the equipment is started, the work area must
be inspected and properly prepared to avoid
personal injury, death and/or damage to equipment.
Make sure the work area is checked for hazardous
fumes, has adequate ventilation for engine exhaust
and sufficient drainage for released fluid. Check the
work area for electrical equipment, connections,
outlets, fixtures, or lines. If any are present they
must be made water tight and the electrical power
to these devices must be shut off to avoid electrical
shocks from fluid contact. The work area should be
clearly marked and roped off to keep unauthorized
people and vehicles from entering. Remove all
loose parts, tools and equipment from the work area
before beginning operation.
All pressure containing devices including wands,
nozzles, guns, hoses, connections, etc., should be
regularly checked for condition. These components
should all be tagged with their tested pressure
capabilities together with the date testing was
performed.
Always be aware of the pressure level in the
system and never connect any equipment to the
system which has a rated or tested pressure
capability below the system operating pressure
.
The equipment must be shut down and the system
pressure released before changing or disconnecting
wands, nozzles, guns, hoses, connections or any
other pressurized system components.
All pressure containing devices including wands,
nozzles, guns, connections, etc., plus all automatic
shut-off, pressure and control equipment should be
treated with care. Protect them from damage by
people, objects and vehicles.
Never
lay them in
dirt, mud, ice or other loose material which could
plug the fluid opening or interfere with their
operation.
Never
use the wand, nozzle, gun, etc. to
pry loose material off items being cleaned.
Before starting operation in a cold environment,
check to make sure there is no ice in the fluid
system and repeat this inspection each time before
operation is restarted.
Before purchasing wands, nozzles, guns,
connections, and hose, etc., manufacturers of these
components should be contacted for detailed
information on the design and safety features
incorporated in their products. After careful study of
various manufacturers products, we recommend
that
only
those wands, nozzles, guns, connections
and hose, etc., be considered for purchase that you
judge to offer the highest quality of design,
construction and safety, since these components
are among the most critical to the safe operation of
high pressure liquid jetting, blasting and cleaning
equipment.
After you have selected and purchased these
components, follow the manufacturer’s instructions
completely in their use.
In summary, high pressure jetting, blasting and
cleaning are inherently dangerous, as the
pressures and flow rates needed to remove
scale, clean, etc. are sufficient to cause
personal injury, death and/or equipment damage
resulting from, but not limited to, any of the
conditions described in the above Danger
