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 Notices.
