INTRODUCTION

Tyco Fire Protection Products (TFPP) hand portables, wheeledunits, and pre-engineered system tanks are designed, produced,and tested in accordance with standards judged by many to be themost rigid in the fire protection industry. The result is safe, effec-tive, first aid fire extinguishers.

To assure continued safe, effective operation, the pressure ves-sels must receive scheduled, periodic maintenance in strict com-pliance with procedures established by the Occupational Safetyand Health Act of 1970. Under the provisions of the Act, the ser-vicing of fire protection equipment must be conducted in accor-dance with the Standards of the National Fire ProtectionAssociation (NFPA) Pamphlets No. 10, 17, 17A, 30, 33, and 96.These standards are available on the NFPA website:www.nfpa.org.

The instructions for testing nitrogen cylinders are not in this man-ual as the test procedures require DOT certification. All ANSULnitrogen and carbon dioxide cartridges should be returned toTFPP for refilling and hydrostatic testing, unless you are a TFPPcontracted cartridge refiller.

TOOLS AND ACCESSORIES

The general use hand tools and accessories listed below are onlythose available from TFPP. For a more comprehensive guide totools, equipment, parts and lubricants used in hydrostatic testingservice operation, refer to the National Association of FireEquipment Distributors Incorporated (NAFED) “Service andRecharge Training Manual.”

HYDROTEST RECOMMENDATIONS

Parts below are taken from NFPA Pamphlet No. 10, 17, 17A, 30,33, and 96. They serve as a general guide to the rules and regu-lations of hydrostatic testing as required by law.

Extinguishers and agent tanks shall be hydrostatically tested atregular intervals as required in the NFPA Standards, or more fre-quently when inspection or maintenance indicates a specific need.Such tests are usually required on extinguisher shells, cylinders,some cartridges and some hose assemblies.

If, at any time, a pressure vessel or agent tank shows evidenceof corrosion or mechanical injury, it shall be subjected to a hydro-static pressure test, or replaced. Important: air or gas should notbe used for pressure testing as failure of a shell could be violentand dangerous. When extinguisher shells, cylinders, cartridgesor hose fail a hydrostatic pressure test, they shall be destroyed.

Table 1 on pages 2-5 is designed to show what TFPP understandsto be the current legal requirements for periodic retest, indicatingboth test intervals and pressures. These requirements are shownfor the two principal authorities having jurisdiction over this type ofproduct: the National Fire Protection Association (NFPA), and theCode of Federal Regulations (DOT, MSHA, and OSHA). It isimportant to understand the jurisdiction of these two authoritiesand how it may affect the product in question. You may wish torefer directly to these principal authorities to make your own inter-pretation of the current legal requirements.

NFPA standards have no force of law in and of themselves unlessadopted by a regulatory entity that is empowered by statute toenforce regulations. However, as consensus standards developedby teams of recognized experts, they represent sound fire safetyprinciples, practices, and procedures, and we recommend thatthey be observed in the case of hydrostatic retesting. Moreover,some states and municipalities have adopted NFPA standards asa part of their fire protection codes, including those parts dealingwith the maintenance and hydrostatic retesting of extinguishers.

OSHA has safety jurisdiction over most workplaces in the U.S.,and as such its regulations have the force of federal law. OSHAhas not adopted NFPA standards for hydrotesting per se, but itsrequirements follow NFPA standards closely.

DOT’s hydrostatic retest requirements apply only to charged pres-sure vessels which are transported in commerce in the U.S. or toforeign countries. Once the product reaches its original destina-tion, DOT rules apply only when the container is reshipped in acharged condition or being re-filled.

MSHA has safety jurisdiction over mines and generally referencesthe appropriate NFPA and DOT regulations for additional guide-lines on extinguisher hydrostatic testing.

It will be noted that there are some gaps and overlapping in thelegal requirements for periodic hydrostatic retesting of some ves-sels. However, appropriate retest intervals and test pressureshave been determined for such vessels through the NFPACommittee process and/or TFPP’s own research and experience.In many cases, compliance to the NFPA standards may put you incompliance with OSHA. (Refer to the National ConsensusStandards, Appendix B, Subpart L.) A TFPP recommendation isindicated for each of the pressure vessels in Table 1, pages 2-5.

In states where the OSHA regulations differ from local regulationsor statutes, the Office of the State Fire Marshal is available forcounsel.

At intervals not exceeding those specified in Table 1, extinguish-ers shall be hydrostatically tested. For those with a designated testinterval of five years, the first hydrostatic retest may be conductedbetween the fifth and sixth years.

MANUFACTURINg DATES

If the pressure vessel does not have a current hydrostatic testlabel attached to the shell with a recent test date, then the manu-facturing date is the correct date for the periodic testing of theshell. All pressure vessels with dates indicating a need for testingmust be tested to ensure the safety of the shell.

Manufacturing dates for RED LINE extinguishers are available onForm No. F-80193. Pressure vessels not listed on the form havethe date of manufacture on the nameplate; or steel stamped onthe base of the shell, under the elbow, above the elbow, on thebottom, on the collar of the shell, on the crown of the shell(wheeled dry chemical), on the bottom of the skirt (NM FE-36models), or on the hanger lug (K Class and water models).

SAFETY CONSIDERATIONS

The purpose of hydrostatic retest is to expose any weakness in apressure vessel that would make it unsafe for use. Accordingly,any pressure vessel under test must be placed in a protectivecage designed to permit visual observation of the extinguisher forevidence of distortion or leakage. When the pressure vessel is toolarge for a test cage (e.g., wheeled dry chemical extinguishers), asubstantial barrier (shield) must be placed between the pressurevessel and the service personnel.

Failure to observe these basic safety measures, and others, canresult in serious personal injury or even death.

Hydrostatic testing should only be performed by trained, qualifiedpersons with suitable testing equipment and facilities. For addi-tional guidance, refer to CFR-29, CFR-49, NFPA-10, and theCompressed Gas Association Pamphlets “C-6,” “C-6.1,” and “C-1”which cover visual inspection and hydrostatic test methods.

TFPP does not assume any liability in connection with the hydro-static testing of their pressure vessels by other than company per-sonnel. However, the following safety considerations are offeredas a guide to extinguisher service personnel.

1. Personnel performing hydrostatic testing services shouldhave practical knowledge of test equipment, testing proce-dures, and of testing safeguards as the result of “hands-on”training.

2. Service personnel should wear suitable eye protection, safetyshoes, and any other safety gear prescribed by their employ-er and/or the authority having jurisdiction.

3. A testing service company should maintain a reference libraryof procedures, standards or specifications for compressed andnon-compressed gas cylinders and cartridges, e.g.Compressed Gas Association’s Pamphlets C-1 and C-6;NFPA’s Pamphlets No. 10, 12, 12A, 17, 17A, 30, 33, and 96;OSHA’s Part 1910, Sub Part L – Fire Protection; Department ofTransportation’s Code of Federal Regulations No. 49Transportation, Parts 100-199; and where applicable theCanadian Transport Commissions counterpart regulations.

4. When disassembling components from a pressure vesselpreparatory to test, testing personnel should avoid placing anypart of their body over the pressure vessel.

5. Protective cages or barriers should not be anchored to thefloor during test operations.

6. Severely corroded or mechanically damaged pressure ves-sels should be destroyed, not subjected to pressure test tovalidate personal judgment.

7. Destruction of a pressure vessel should consist (minimal) ofdrilling a hole (1/2 in. (13 mm) diameter) in the shell throughthe UL manifest on the name plate and flattening or filing thefill opening threads to preclude further use of the vesselbeyond scrap material.

8. Service personnel should not under any circumstancesattempt to tighten a leaking connection while the pressurevessel and/or the testing apparatus is under pressure.

9. Test adaptors and fittings should be examined at periodicintervals to make certain the threads are not dangerouslynicked, cross-threaded, corroded or worn.

10. A permanent file should be maintained for each tested pres-sure vessel. This is especially true of a pressure vessel thatevidences a dent or factory made repair that was not severeenough to cause rejection under hydrostatic test.

! WARNINg

HYDROSTATIC TEST FOR PRESSURE VESSELS

The following general instructions are used with Table 2, pages8-15, which lists the specific adaptors required to test the differenttypes of extinguishers.

Always be alert for any indications of damage or inability to oper-ate the extinguisher. No manual can anticipate everything thatcould happen to an extinguisher. In the event that something notcovered in the manual is found, determine whether any potentialfor damage, effect on operation, or safety exists and repair orreplace, as necessary.

1. Carefully release any pressure from the extinguisher andremove external and internal parts from the shell. Install safe-ty shipping cap on gas cylinder or cartridge (if part of assem-bly) and place all parts in a safe location. (Refer to theOperation, Recharge, Inspection, and Maintenance Manualprovided with the extinguisher for proper procedures.)

Cartridge operated and wheeled unit extinguishers musthave gas tube removed prior to hydrostatic test (unlesswelded to the shell). Failure to remove will result in damageto the gas tube rubber.

2. Remove agent from shell and place in a labeled container.(Closed removal system recommended to limit exposure topersonnel.)

Note: Agent removed from Pre-engineered Systems shall bereplaced.

3. Remove all traces of dry chemical from the shell using dry airor nitrogen.

Restrain object being cleaned and wear proper protectiveclothing and eye protection.

4. Thoroughly examine the entire shell for signs of corrosion ormechanical damage. Refer to the “Standards for VisualInspection of Steel Compressed Gas Cylinders,” PamphletCGA C-6, from the Compressed Gas Association, Inc.

Do not perform hydrostatic test on shell in poor condition. Ifthe shell shows evidence of parent metal missing due tosevere corrosion or mechanical damage, it must bedestroyed and replaced. (See page 6, step 7.)

5. Connect the appropriate adaptors, fittings, and hose from thehydrostatic pump as indicated in Table 2, pages 8-15.

Note: If shell has a burst disk (safety release valve) replaceit with the appropriate plug.

6. Place shell in test cage or place shield between shell and allpersonnel.

7. Open vent valve and pump water into the shell. When waterstarts to flow freely from the valve, rock the shell gently torelease all air entrapped in the shell – then close vent valve.

Note: On the stationary and wheeled units remove fill capassembly and allow water to overflow fill opening. The ventvalve should not be closed until water flows freely from thevalve. Rock tank gently to make certain all air is removed;return fill cap assembly to the shell and hand tighten.

All air must be removed. Failure to comply may cause theshell to rupture resulting in severe personal injury or death.

8. Turn on hydrostatic pump and apply pressure at a rate-of-pressure rise to reach the designated test pressure within 1minute. (See Table 1, pages 2-5 for test pressure.)

9. Maintain the test pressure for 1 full minute observing shell forany distortion or leakage. If no distortion or leakage is notedand the test pressure has not dropped, the hydrostatic test issuccessful. Stop the hydrostatic pump and open the ventvalve to relieve the pressure in the shell.

Note: Any shell that fails this hydrostatic test must bedestroyed (see page 6, step 7) to prevent its further use as apressure vessel. Shells passing this hydrostatic test musthave all water and all traces of moisture completely removedbefore reassembly of components.

Relieve pressure through vent valve only. Do not attempt toremove adaptors, fittings, fill caps, etc., until pressure isreleased.

10. Disconnect all test fittings and remove water from the shell.Completely dry the shell (for all non-water type of extinguish-ers) using a commercial warm air dryer that does not exceeda temperature of 150 °F (65.5 °C). Do not place dry chemicalin shell until the shell and all attachments are completely dry.

11. Perform hose test (see page 16) on hose assemblies as des-ignated in Table 1, pages 2-5.

12. Examine all parts; replace worn or damaged parts with origi-nal factory ANSUL components. Reassemble and refill shellaccording to the Operation, Recharge, Inspection, andMaintenance Manual provided with the extinguisher.

13. Record hydrostatic test information (month, year, test pres-sure, name or initials of person performing the test, and nameof agency performing the test) on the hydrostatic test recordlabel (see Figure 1), Part No. 11790 (or equal) and attach it tothe shell. Update the permanent file on each tested extin-guisher.

HYDROSTATIC HOSE TEST

Extinguisher hose assemblies are to be hydrostatically tested asspecified in NFPA at a test interval equivalent to the extinguisheron which the hose is installed.

1. Remove the hose and nozzle assembly from the extinguishershell and disconnect the nozzle.

Note: The hydrostatic test is performed only on the hose withthe nozzle assembly removed.

2. Remove all traces of dry chemical from the hose using dry airor nitrogen.

Restrain object being cleaned and wear proper protectiveclothing and eye protection.

3. Examine the hose, hose couplings and “O” ring (when includ-ed). Replace any hose that has cuts, abrasions, cracks, or adeformed exterior. Replace couplings that appear corroded,cracked, cross-threaded or worn. Replace “O” ring if neces-sary.

4. Assemble the appropriate coupling/adaptor (see Table 3, col-umn A) to the vent valve and connect the assembly to oneend of the hose.

5. On the other hose end attach designated coupling/adaptor(see Table 3, column B) and connect to the hydrostatic pumphose (see Figure 2).

FIgURE 2

6. Place the fitted hose assembly in an appropriate test cage; orplace a substantial shield between the hose and all personsin the area.

Position the vent valve slightly higher than the balance ofthe assembly to make certain all air is removed before test.

7. Open vent valve and pump water into the hose. When waterstarts to flow freely and all entrapped air is bled off, close thevent valve.

8. Apply pressure at a rate-of-pressure rise to reach the testpressure listed in Table 1 on pages 2-5 within 1 minute. Thenmaintain the test pressure for another full minute, observingthe hose and couplings for any distortion or leakage. If no dis-tortion or leakage is noted and the test pressure has notdropped, the hydrostatic test is successful. Stop the hydro-static pump and open the vent valve to relieve the pressure inthe hose.

Note: Any hose assembly that fails this hydrostatic test mustbe destroyed to prevent its further use in connection with apressure generating device.

9. Disconnect all test fittings and pour the water from the hoseassembly.

! CAUTION

! CAUTION

10. Use a heated air stream (or suitable commercially availablehose dryer) that does not exceed a temperature of 150 °F(65 °C) for complete, effective drying of the hose (see Figure3).

11. Reconnect nozzle to hose and return the complete assembly,to its original extinguisher shell.
