•
Wear a face shield when required by operating
instructions.
•
Do not remove protective shields from high-pressure
tubing. If shields are removed for servicing, they
must be replaced before starting the system.
•
Torque all fittings to the manufacturer’s torque
specifications.
•
Stepping or leaning on high-pressure tubing can
break connections, causing leakage.
•
Use only high-pressure fittings, valves, and tubing
certified for 60,000 psi (4138 bar) when making al
-
terations or additions to the high-pressure water sys
-
tem.
•
Do not alter or eliminate stress relief tubing coils.
•
Follow the tubing manufacturer’s recommendations
for high-pressure tube bending radii.
•
Do not exceed specified operating pressures for
high-pressure water system components.
•
Do not over-torque fittings or bend swivels
excessively.
•
Follow the manufacturer’s recommendations for ser-
vicing the equipment, and use only original manu-
facturer replacement parts.
•
Follow the manufacturer’s system startup procedure
to ensure safe operation.
•
Use care when lifting equipment covers during
operation.
WARNING
NEVER point a waterjet cutting or cleaning tool
at yourself or at any person. Do not aim any
waterjet tool at anything you do not want to cut.
Protective clothing
Personnel operating hand-held, high-pressure water cut
-
ting or cleaning equipment and those working nearby
should wear the protective clothing and safety devices
described in this chapter.
FLOW recommends that work-site safety personnel ap
-
prove all safety equipment and clothing for everyone
working around waterjet equipment.
Eye protection
•
At a minimum, operators must wear
safety glasses with side shields and a vi
-
sor, or goggles and a visor, to gaurd
against spray and flying debris.
•
All eye protection shall meet
appropriate ANSI requirements for that
type of eye protection.
•
Some states and countries have their
own eye protection rules that must be
followed.
Head protection
•
Helmets must be worn at all times by all
personnel within the work area. Helmet
material must withstand mechanical
shock to 10 G in 8 ms without
fracturing.
Hand protection
•
The operator must wear gloves at all
times. Leather gloves are preferred.
Foot protection
•
Safety footwear with steel toe-caps at
least 0.02 in. (5 mm) thick must be
worn. The toe cap must cover at least
30% of the footwear length.
•
For some applications, footwear must
be equipped with metatarsal guards to
provide instep protection.
Hearing protection
•
Operators and other personnel exposed
to noise levels of more than 90 dBa for
more than 1 hour must wear suitable
ear protection. Ear plugs and muffs are
usually adequate.
Body protection
•
Waterproof garments only protect the
operator from spray and flying debris.
They do NOT deflect direct jet
impact.
