Section 1: Safety

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.

Incorrect Use of High Pressure Waterblast

Equipment May Cause Serious Injury

Read these instructions in their entirety

before using any JETSTREAM products.

4PI-19 8 December 2020

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-19 8December 2020

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

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-19 8 December 2020

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.

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.

7PI-19 8December 2020

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.

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 22,000 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.

2. Nozzle ﬂow ratings must be compatible with pump discharge and

pump pressure rating. (See Nozzle Flow Rating Chart on page 27.)

3. Use only nozzles with a manufacturer’s pressure rating of at least the

8PI-19 8 December 2020

operating pressure or a burst rating or no less than 3.0 times the desired

operating pressure.

4. Prior to installation, make sure the nozzle has no clogged oriﬁces.

5. Apply 3 - 4 wraps of Teﬂon tape to male connection threads on the

nozzle. 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.

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. 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 J-Force and clean immediately.

8. 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 22,000 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.

5. Do not use a lance which has damaged or missing threads.

6. Clearance between lance and tube deposits must be sufﬁcient to

allow unrestricted backﬂow of water and debris. With tubes containing

hard deposits this clearance should be 1/8” minimum on the diameter

(or 1/16” per side) of the lance. With tubes containing soft, pliable

deposits this clearance should be greater. Insufﬁcient side clearance

may cause lance to blow back toward operator.

7. Serious injury may occur should a lance with live nozzle

9PI-19 8December 2020

exit tube. Use anti-withdrawal device to prevent lance from exiting tube

unexpectedly.

8. The following JETSTREAM lance accessories are strongly

recommended for safer lance operation:

A. Lance Strain Relief - Helps prevent lance inlet end ﬁtting failure.

B. Lance Stinger - Affords the operator greater control of nozzle.

Establishes a “safety zone” so operator knows when nozzle is about to

exit tube; will eliminate possibility of nozzle and lance “double back”

toward operator within large diameter pipe.

C. Anti-withdrawal device prevents the lance from exiting the tube

or pipe. Contact JETSTREAM for additional information regarding these

products.

9. Use only nozzles designed for use with ﬂex lances (i.e. nozzle

drilled with sufﬁcient rearward oriﬁces so nozzle pulls lance through

tube.)

10. If lance end ﬁttings do not have wrench ﬂats, use properly adjusted

smooth jaw plier wrench (JS PN 64119) to connect lance to pressure

source and nozzle onto lance. Apply wrench on lance and ﬁtting directly

behind end ﬁtting thread (not on ﬁtting ferrule or collar) when

installing nozzle on lance. Do not clamp on the lance hose itself with vise

when installing nozzle.

11. Avoid rough handling, stretching or straining of lance.

12. Never attempt to “ramrod” ﬂex lance through blockages or to repair

or recouple lances.

13. After use, drain, coil and store lance properly. Be sure safety tags

remain intact.

RIGID TUBE CLEANING LANCES

1. Read General Safety section and Nozzle Safety Warnings prior to

connecting rigid lances.

2. Do not use a rigid lance with a burst rating less that 3.0 times the

pressure at which it will operate. 10,000 psi operating pressure rigid

lances must have a minimum 30,000 psi burst rating. Do not use a rigid

lance that has an unknown burst or unknown manufacturer’s operating

pressure rating.

3. Clearance between lance and tube must be sufﬁcient to permit the

unrestricted backﬂow of water and debris. With tubes containing hard

deposits this clearance should be 1/8” minimum on the diameter (or

1/16” per side) of the lance. With tubes containing soft, pliable deposits

10 PI-19 8 December 2020

this clearance should be greater. Insufﬁcient side clearance may cause

lance to blow back toward operator.

4. Be sure nozzle, lance and adapter thread sizes are compatible before

installing nozzle and adapter on lance. Do not use a rigid lance that has

damaged or missing threads.

5. Use wrench ﬂats (when available) or a properly adjusted smooth jaw

plier wrench (JS PN 64119) to connect lance. Do not use pipe wrench as

wrench marks will cause high pressure components to crack and fail.

6. A rigid lance over 4 ft long requires two men for support and safe

operation. Operator at tube should use a foot control gun so he can

instantly relieve system pressure in case of emergency.

7. When using and moving lance, support it in a manner to avoid stress

and possible breakage at inlet end connection.

8. Never ”ramrod” lance into tube blockage.

9. Transport and store lances in tubes or racks to avoid bending,

corrosion or other damage. Damaged lances (bends, mars) should be

removed from service.

HIGH PRESSURE FITTINGS

1. Read General Safety section prior to installing ﬁttings in system.

2. Use non-brass or non-cast iron ﬁttings which are made for high

pressure waterblast use.

3. Use only high pressure ﬁttings which are clearly marked with the

operating pressure.

4. High pressure ﬁttings should have a known burst rating of not less than

3.0 times system operating pressure. Never use a damaged or corroded

ﬁtting or one with damaged or missing threads.

5. Use only high pressure rated ﬁttings and hose in the waterblast

system. For 10,000 psi waterblast service all ﬁttings and hose should

have a minimum burst rating of 25,000 psi; for 15,000 psi service they

should have a minimum burst rating of 37,500 psi; for 20,000 psi service

they should have a minimum burst rating of 50,000 psi.

6. Use wrench ﬂats (when available) or a properly adjusted smooth jaw

plier wrench (JS PN 64119) to tighten ﬁttings. Avoid using pipe wrench as

wrench marks will cause high pressure ﬁttings to crack and fail.
