Section 1: Safety
This section includes all the same information included in the yellow
JETSTREAM SAFETY WARNING pamphlet.
This information was prepared to aid in the identification of potentially
unsafe conditions when using high pressure waterblast equipment. It
should be noted that other potential hazards may exist which might have
not been mentioned in this brochure.
In all cases, JETSTREAM products are sold with the understanding that
the purchaser agrees to thoroughly train all operating and maintenance
personnel in the correct and safe installation, operation of maintenance
of waterblast equipment and to provide adequate supervision of person-
nel at all times.
Read the following in its entirety before connecting, operating or repair-
ing equipment. Purchasers and operators also should be familiar with
the current version of the “Recommended Practices for the Use of High
Pressure Waterjetting Equipment” published by the Waterjet Technology
Association, as well as any applicable OSHA regulations, standards and
guidelines.
Should any questions arise concerning safe and proper procedure,
contact JETSTREAM prior to the installation or use at (800) 231-8192 or
(832) 590-1300.
Incorrect Use of High Pressure Waterblast
Equipment May Cause Serious Injury
Read these instructions in their entirety
before using any JETSTREAM products.
4PI-078 June 2021
GENERAL WATERBLAST
1. Use only clear, clean water in high pressure system.
2. Place barricades with warning signs or barricade tape around work
area.
3. Outfit all operators with Personal Protective Equipment (PPE). Hard
hat with plastic face shield, rainsuit, non-skid knee boots with metatar-
sal protection, gloves, ear protection and body armor rated for operating
pressures are considered minimum safety equipment. Proper respiratory
protection is required where dangerous fumes or dust is present or
created by the waterblasting operation. Follow applicable OSHA
regulations, standards and guidelines regarding the use of respiratory
protection if harmful fumes or dust is present during, or created by the
waterblasting operation
4. Use products intended for high pressure waterblasting only.
5. No product should be altered without written consent of the
manufacturer.
6. Read and follow all manufacturer’s instructions prior to using any
waterblast product. Contact manufacturer.
7. Thoroughly review alternative methods before initiating any potential-
ly dangerous waterblasting operation. Fully automated, semi-automated,
and/or mechanized methods should all be considered first. Contact the
applicable waterblasting manufacturers for assistance and recommen-
dations.
8. The operator handling the cleaning device (with nozzle) must always
have control of water pressure. A surface cleaning operator should
operate a trigger style control gun capable of instantaneously stopping
pressure to nozzle. A tube cleaning lance operator should operate a foot
gun capable of instantaneously stopping pressure to the lance.
9. Inspect the condition of all components prior to use. Use no items
which are in questionable condition.
10.Check the condition of thread connections prior to the make-up of
any high pressure connection. Use Teflon tape and anti-seize on male
pipe (NPT) thread for sealing purposes. Do not let tape overlap the male
pipe thread end. Tape fragments may enter system water stream and
clog nozzle’s orifices.
Do Not use a component with missing or damaged threads on the
high pressure connections.
5PI-078June 2021
11.Properly tighten all high pressure connections. All NPT connections
must have a minimum engagement of four (4) threads. Pipe (NPT)
connections should be made up hand tight plus two (2) full wrenched
turns. Do not tighten NPT threads past two (2) wrenched turns.
Use wrench flats (when available) or a properly adjusted
smooth jaw plier wrench (JS PN 64119) for tightening components.
Avoid using pipe wrench as wrench marks will cause high pressure
components to crack and fail.
12.All high pressure hose connections require a hose restraint (whip
check), including connection at fluid end discharge.
13.Before attaching a nozzle to the control gun or tube cleaning lance,
operate the pump at low speed to purge dirt and debris from system.
Dirt and debris can clog nozzle orifice(s) and cause excessive sys-
tem pressure which could lead to a lance failure.
14.With nozzle installed, operate the pump at a low speed (low
pressure) for test. Should system repairs or adjustments be necessary,
stop pump and relieve all pressure before making required repairs or
adjustments. The pump operator should watch the nozzle operator at all
times in case any difficulty arises and it becomes necessary to depres-
surize system. If the pump operator does not have a clear line of sight
to the nozzle operator, it may be necessary to have another employee
available to communicate between the nozzle and pump operators.
15.With the system operating properly, increase pump speed slowly
until operating pressure is reached and adjusted. Pressure adjust-
ments should always be made slowly. The nozzle operator shall be
warned before any pressure adjustment is made by the pump operator.
A sudden change in reaction force may cause the nozzle operator to lose
balance.
16.Use minimum pressure required for cleaning. Do not exceed the
operating pressure of the system’s lowest pressure-rated component.
All equipment pressure rating markers and warning tags should be left
intact.
17.Waterblast operators must be made aware that the cleaning noz-
zle’s discharge jets(s) can inflict serious body wounds. Supervisors
should demonstrate the potential danger of discharge jet(s) by showing
all new operators the effect of a waterjet by cutting a scrap piece of
wood such as a 2” x 4”.
6PI-078 June 2021
18.If equipment malfunctions or a system malfunction is suspected,
immediately stop cleaning activity and relieve the pressure in the system
before attempting any repairs. Always follow the manufacturer’s repair
instructions.
19.Only trained persons should be authorized to perform any mainte-
nance or repair.
20.Following any repairs, the system should be operated at low pressure
for test. Bring equipment up to operating pressure slowly.
21.For shutdown in freezing conditions, even for brief periods, drain
water from all components. Prior to starting operations in freezing
conditions, the operation of all equipment components must be checked
carefully to make sure components are not frozen and can be operated.
22.Store components properly by protecting them from damage when
not in use. Be sure all safety warning tags and markers remain intact.
CONTROL GUNS AND DEVICES
1. Read General Safety section before connecting or using control guns
or control devices.
2. Thoroughly review alternative methods before initiating any poten-
tially dangerous shotgunning or hand lancing operation. Fully automated,
semi-automated, and/or mechanized methods should all be considered
first. Contact the applicable waterblasting manufacturers for assistance
and recommendations.
As described in the Industry Best Practices for the Use
of High Pressure Waterblasting Equipment published by the Waterjet
Technology Association, the standard shotgun barrel length shall be a
minimum length of 48” to minimize the risk of nozzle discharge
accidentally striking the operator’s feet, legs, or body. See Section
11.10.6. The WJTA has recognized that deviations or variances from
these best practices may be acceptable under certain circumstances.
See Section 2.7. If users believe deviation from this 48” standard is ac-
ceptable, they should follow procedures outlined in Section 2.7 to
minimize risk to the operator. Among other things, users should ensure
that other measures to perform the work have been considered and
exhausted, senior safety management and customers have considered
and approved the deviation, operators have been properly trained and
warned about any increased risk associated with the deviation, and
operators are wearing all appropriate PPE, including body armor rated
7PI-078June 2021
for the operating pressure.
3. Prior to use, thoroughly check control gun or control device for
smooth and proper operation. Control guns and control devices should
also be checked for proper operation before each operating shift. Do not
use any control gun or control device that has not been checked before
your operating shift.
4. A control gun operator using a hand-held gun should position and
brace his body for the gun’s rearward reaction force before depress-
ing gun trigger. Gun’s rearward reaction should be a maximum force of
40 to 50 lbs. (or 1/3 body weight of operator.) The control gun operator
should maintain firm, solid footing to counter gun’s rearward reaction.
5. The use of a Safety Shroud and a Safety Whip Hose with handheld
control guns is strongly recommended for additional operator protection
against a burst occurring in the high pressure hose connected to the
gun. Use of Hand Grip and Shoulder Stock in hand-held control guns will
provide greater operator comfort and safety.
6. Fall protection should be provided when blasting on scaffolding or
sloping surface per OSHA guidelines. Do not operate a hand-held gun
while standing on slippery surfaces.
7. The control gun operator should always start blasting with a low
system pressure and slowly increase blasting pressure. Depress and
release control gun trigger/pedal several times at operating pressure to
check the control gun’s operation before starting cleaning operations.
8. A dump type control gun should always open fully and reduce the
system pressure to near zero immediately when its trigger/pedal is
released. If this type of control gun does not relieve system pressure
immediately or system pressure does not fall below 200 psi when trig-
ger/pedal is released, do not use the control gun.
9. The control gun operator should never pass a control gun to another
operator without first stopping the pump and water flow to the control
gun. Passing off a control gun without first stopping system waterflow is
dangerous because of possible accidental trigger actuation.
10.Do not use a control gun or control device that has malfunctioned or
you suspect malfunctioned without having it repaired and/or thoroughly
checked for proper operation by a qualified high pressure maintenance
mechanic or your supervisor.
11.Do not use a control gun that does not have a trigger guard.
12.Never tie, wedge or clamp a control gun’s trigger in the closed
position.
8PI-078 June 2021
13.All electric throttle control cords should be rated for wet conditions.
All cord connections and switches should be kept out of water.
14.Any hose used for transporting dump water back to pump should
have a large enough diameter and short enough length so that poten-
tially dangerous back pressure is kept low. Protect hose from traffic.
15.Hand-operated control guns should never be used as foot-operated
devices.
PRESSURE RELIEF DEVICES
1. Read General Safety section prior to installing Relief Valve and/or
Pressure Relief Devices.
2. A waterblast system should include both primary and secondary
pressure relief protection:
A. For primary protection a primary rupture disc assembly or
spring-loaded relief set at 1.2 times, maximum operating pressure is
recommended (i.e. relief valve is set at 12,000 psi if maximum
operating pressure is 10,000 psi)
B. For secondary protection a rupture disc assembly containing a
manufacturer’s approved disc having a burst rating of 1.4 times
maximum operating pressure is recommended.
Only use a rupture disc holder which will NOT permit the
use of coins or other objects in place of discs.
3. Relief devices should never be mounted so the discharge could strike
personnel.
4. Never install a shut-off valve between the pump and relief device.
5. “Set pressure” must be prominently displayed on all relief devices.
Never install or use a relief device unless its “set pressure” is known.
6. Do not attempt to correct a leaking relief valve by increasing spring
tension as this will increase its set pressure.
7. Do not use a pressure relief valve as a combination relief and throt-
tling device.
8. Keep relief valve dry during freezing conditions.
NOTE: Pressure relief devices are imperative for the protection of both
operator and equipment from dangerous over-pressurization.

HIGH PRESSURE HOSE
1. Read General Safety section prior to connecting high pressure hose.
2. Do not use a high pressure hose with a burst rating less that 2.5 time
the pressure at which it will operate. 10,000 psi operating pressure high
pressure must have a minimum 25,000 psi burst rating. 8,000 psi
operating hose must have a minimum 22,500 psi burst rating.
3. Do not use a high pressure hose that has an unknown burst rating or
manufacturer’s operating pressure rating.
4. Use of a Safety Shroud is strongly recommended for added safety
where hose connects to control gun.
5. Use of hose restraint (whip check) is required at all hose connections,
including connections at fluid end.
6. Always apply wrench to wrench flats when making threaded
connections. Do not apply wrench on the end fitting ferrule (collar)
7. Remove hose from service if:
A. Cover is damaged and reinforcing wires are exposed to rust and
corrosion;
B. Cover is loose, has blisters or bulges;
C. Hose has been crushed or kinked;
D. End fitting shows evidence of damage, slippage, or leakage.
E. Hose has been exposed to pressures greater than 50% of burst
rating; or
F. Hose is three or more years old, regardless of condition.
8. Disconnect, drain, coil and store hose properly after use.
9. Never attempt to repair or recouple high pressure hoses in field. High
pressure hose end fittings are the permanently crimped type and can
only be properly installed with hydraulic crimping equipment.
NOZZLES
1. Read General Safety section. Read the appropriate Safety Warning
(i.e. Flexible Tube Cleaning Lances or Rigid Tube Cleaning Lances) prior
to installing nozzle on lance.
2. Nozzle flow ratings must be compatible with pump discharge and
pump pressure rating. A flow rating is stamped on the side of
JETSTREAM’S nozzles. (See Nozzle Flow Rating Chart in JETSTREAM
Catalog.)
3. Use only nozzles with a manufacturer’s pressure rating of at least the
operating pressure or a burst rating or no less than 3.0 times the desired
operating pressure.
10 PI-078 June 2021
4. Prior to installation, make sure the nozzle has no clogged orifices.
5. For 15,000 psi models - Apply 3 - 4 wraps of Teflon tape to male
connection thread on the barrel. Apply anti-seize compound over the seal-
ant tape for additional protection against galling in connection threads.
Wrench connection 1 1/2 - 2 turns past hand tight. A minimal thread
engagement of four (4) threads should exist on all Jetstream NPT pipe con-
nections.
For 22,500 psi models - Apply anti-gall compound to the gland threads
and male cone on control gun front barrel. DO NOT use Teflon tape. Check
blast nozzle size before installing the nozzle. Make sure the nozzle orifices
are not too small in order to prevent excessive system pressure when the
gun’s control valve trigger/pedal is depressed.
6. Use wrench flats (when available) or a properly adjusted
smooth jaw plier wrench (JS PN 64119) to tighten nozzle. Avoid using pipe
wrench as wrench marks will cause nozzles to crack and fail.
7. Special nozzles requiring a thread locking pin must have the pin
installed prior to use or the nozzle may unscrew from the lance while in
service and cause the lance to blow back toward the operator.
8. With nozzles requiring adjustment, always read applicable instructions.
9. Blocked orifice(s) can cause excessive system pressure and failure. If
orifice(s) appear clogged or partially blocked with dirt or debris, remove
nozzle from control gun or lance and clean immediately.
10.Remove nozzle from service if:
A. Nozzle is split or damaged;
B. Nozzle sidewall is worn by more than 25% at any point;
C. Nozzle’s ability to hold pressure is questionable
D. Threads are missing or damaged
FLEXIBLE TUBE CLEANING LANCES
1. Read General Safety section and Nozzle Safety Warnings prior to
connecting flex lances.
2. Do not use a flex lance with a burst rating less than 2.25 times the
pressure at which it will operate. 10,000 psi operating pressure flex lances
must have a minimum 22,500 psi burst rating. 8,000 psi operating pres-
sure flex lances must have a minimum 18,000 psi burst rating.
3. Do not use a flex lance that has an unknown burst or unknown
manufacturer’s operating pressure rating.
4. Never use a lance which is kinked, worn, frayed or whose abilities
to hold pressure is questionable.
