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 personnel

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 “Industry Best 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.

ANGER

Incorrect Use of High Pressure Waterblast

Equipment May Cause Serious Injury

Read these instructions in their entirety

before using any JETSTREAM products.

4PI-123May2017

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 metatarsal

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 potentially

dangerous waterblasting operation. Fully automated, semi-automated,

and/or mechanized methods should all be considered first. Contact the

applicable waterblasting manufacturers for assistance and recommenda-

tions.

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-123May 2017

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.

CAUTION

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

system 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 depressur-

ize 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 nozzle’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-123May2017

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 potentially

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.

ARNING

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 for

7PI-123May 2017

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 depressing

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 protec-

tion 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 trigger/

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-123May2017

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 potentially

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.

ARNING

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 throttling

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.

9PI-123May 2017

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-123 May 2017

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

sealant 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 connections.

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.

CAUTION

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 operat-

ing pressure 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.
