(e.g., pipe wrenches) which can damage equipment, is not recommended, particularly

of
the correct size and rating for the unit.
F.
Protective Clothing and Personnel Protection
1.
OSHA
compliance - All applicable OSHA regulations covering personal protective
equipment shall be followed.
2.
Head protection - All operators shall be issued with suitable head protection which
shall be worn, where possible. This should also include a full face shield.
3.
Eye protection - Suitable eye protection (i.e., adequate for the purpose and of
adequate fit on the person) shall be provided
to
all operators
of
high pressure water
jetting equipment, and must be worn within the working area. Additionally, several
states have regulations governing eye protection which must be conformed with.
Caution:
Where liquids liable to cause eye damage are encountered,
it
may
be
necessary to use either a combination
of
visor
and
goggles
or
a full face
shield.
Where liquids liable to cause eye damage are encountered, it may be necessary to use
either a combination
of
visor and goggles or a full hood shield.
4.
Body protection - All operators should be supplied with suitable waterproof clothing
having regard
to
the type
of
work being undertaken. Garments should provide full
cover to the operator-including the arms. Liquid or chemical resistant suits shall be
worn when there is a reasonable probability
of
injury that can be prevented by such
equipment.
5.
Hand
protection - Adequate hand protection should be supplied
to
all operators and
shall be worn when there is a reasonable probability
of
injury that can be prevented by
such equipment.
6.
Foot protection - All operators should be supplied with waterproof boots with steel or
aluminum toe-caps. A metatarsal guard should also be used by water jetting lance/gun
operators.
7.
Hearing protection - Most high pressure water jetting operations produce noise levels
in excess
of
90 dB (A), consequently, suitable ear protection issued in accordance with
OSHA standards must be worn and provision should be made for its regular inspection
and maintenance. All personnel and operators should receive instruction in the correct
use of ear protectors so that noise exposure lies within the limits
as
specified by OSHA.
8.
Respiratory protection - A respiratory protection program shall be implemented
where there is a reasonable probability
of
injury that can be prevented by such a
program.
