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 visor, or goggles and
a visor, to guard against spray and
flying debris.
•
All eye protection shall meet ap
-
propriate 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 0.02-in. (5 mm) thick
(minimum) must be worn. The
toe cap must cover at least 30%
of the footwear length.
•
For some applications, footwear

Hearing protection
•
Operators and other personnel
exposed to noise levels of more
than 90 dBa for more than

Waterproof garments only protect
the operator from spray and flying
debris. They
DO NOT provide any
protection from direct jet impact.
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.
